Hubble Captures New View of Colorful Veil
In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous — and frequently photographed — supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the Sun that exploded about 10,000 years ago, the Veil Nebula is situated about 2,400 light-years away in the constellation Cygnus. Hubble images of this photogenic nebula were first taken in 1994 and 1997, and again in 2015.
This view combines images taken in three different filters by Hubble’s Wide Field Camera 3, highlighting emission from hydrogen, sulfur, and oxygen atoms. The image shows just a small fraction of the Veil Nebula; if you could see the entire nebula without the aid of a telescope, it would be as wide as six full Moons placed side-by-side.
Although this image captures the Veil Nebula at a single point in time, it helps researchers understand how the supernova remnant evolves over decades. Combining this snapshot with Hubble observations from 1994 will reveal the motion of individual knots and filaments of gas over that span of time, enhancing our understanding of this stunning nebula.
NASA’s SpaceX Crew-10 to Explore Deep Space Exercise, Health
During NASA’s SpaceX Crew-10 mission to the International Space Station, which is scheduled to launch in March, select members of the four-person crew will participate in exercise and medical research aimed at keeping astronauts fit on future long-duration missions.
Crew members living and working aboard the space station have access to a designated training area outfitted with a weight-lifting system, a stationary bike, and a specialized treadmill called T2. The space station is expansive enough for bulky exercise equipment that helps preserve the health and performance of astronauts in space and when they return to Earth.
However, as NASA looks to explore beyond low Earth orbit, the agency anticipates future spacecraft will not have room for large exercise equipment, like treadmills. Since walking and running are essential parts of workouts aboard the space station, NASA does not fully understand how long-duration spaceflights without a treadmill will impact crews’ health and motor functions. Consequently, NASA researchers are adjusting astronauts’ training regimens, including eliminating the use of the treadmill in some cases, to study ways that maintain crews’ strength, fitness, bone health, and balance.
In an ongoing study called Zero T2, expedition crews are divided into three groups with different workout regimens. One group continues exercising normally, using all the available equipment aboard the orbiting complex. A second group forgoes using the treadmill, relying solely on the other available equipment. While a third group will only exercise using a new, experimental, less bulky workout machine. NASA compares the groups’ health data collected before, during, and after flight to determine if the lack of treadmill use negatively impacts the crews’ fitness, muscle performance, and recovery after return to Earth.
“A treadmill takes up a lot of mass, space, and energy. This is not great for missions to Mars where every kilogram counts,” explained NASA astronaut Matthew Dominick, who participated in the same study while serving as commander of NASA’s SpaceX Crew-8 mission in 2024. “The Zero T2 experiment is helping us figure out if we can go without a treadmill and still be healthy.”
Results of the Zero T2 study will help researchers determine how treadmill-free workouts may affect crew health, which will, in turn, help NASA build realistic exercise protocols for future deep space missions. Additionally, this investigation could support design improvements for exercise devices used to prevent or treat bone, muscle, and cardiovascular health on Earth.
Beyond the Zero T2 study, select NASA crew members will perform additional studies supported by the agency’s Human Research Program during their mission. Participating crew will conduct medical exams, provide biological samples, and document spaceflight-related injuries, among other tasks.
“Astronauts choose which studies to participate in based on their interests,” explained Cherie Oubre, a NASA scientist at the agency’s Johnson Space Center in Houston, who helps oversee human research studies carried out aboard the space station. “The experiments address important risks and gaps associated with human spaceflight.”
One set of experiments, called CIPHER (Complement of Integrated Protocols for Human Exploration Research), will help researchers understand how multiple systems within the human body adjust to varying mission durations. CIPHER study members will complete vision assessments, cognitive tests, and MRI scans to help provide a clearer picture of how the entire body is affected by space.
“The CIPHER experiment tracks changes in the eyes, bones, heart, muscles, immune system, and more,” Oubre said. “The investigation provides the most comprehensive overview of how long-duration spaceflight affects the entire human body ever conducted, helping us advance human expeditions to the Moon, Mars, and elsewhere.”
Some crew members also will contribute to a core set of measurements called Spaceflight Standard Measures. The measurements represent how the human body and mind adapt to space travel over time and serve as a basis for other spaceflight studies like CIPHER. Additionally, crew members may provide biological samples for Omics Archive, a separate study analyzing how the body reacts to long-duration spaceflight at the molecular level.
In another study, select crew members will test a potential treatment for spaceflight-associated neuro-ocular syndrome, a condition associated with brain changes and swelling of the back of the eye. Researchers are unsure what causes the syndrome or why only certain astronauts develop it, but the shift of bodily fluids toward the head in weightlessness may play a role. Some scientists believe genetics related to how the body processes B vitamins may affect how astronauts respond to those fluid shifts. Participating crew will test whether a daily B vitamin supplement can ease or prevent the development of symptoms. They also will investigate if cuffs worn on astronauts’ thighs to keep fluids in the legs could be an effective intervention.
Upon return, the select crew members will complete surveys that record any discomfort or injuries associated with landing, such as scrapes and bruises. Results of the surveys ̶ when combined with data retrieved by sensors in the vehicle ̶ will help researchers catalog these injuries and improve the design of spacecraft.
Crew members began participating in the studies about a year before their mission, learning about the work and offering baseline health data. They will continue to provide data for the experiments for up to two years after returning home.

2025 Aviation Weather Mission: Civil Air Patrol Cadets Help Scientists Study the Atmosphere with GLOBE Clouds
2 min read
2025 Aviation Weather Mission: Civil Air Patrol Cadets Help Scientists Study the Atmosphere with GLOBE CloudsThe Science Activation Program’s NASA Earth Science Education Collaborative (NESEC) is working alongside the Civil Air Patrol (CAP) to launch the 2025 Aviation Weather Mission. The mission will engage cadets (students ages 11-20) and senior members to collect aviation-relevant observations including airport conditions, Global Learning and Observations to Benefit the Environment (GLOBE) Cloud observations, commercial aircraft information (including registration number and altitude), and satellite collocations provided by the NASA GLOBE Clouds team at NASA Langley Research Center. This mission results from a highly successful collaboration between NESEC and CAP as cadets and senior members collected cloud, air temperature, and land cover observations during the partial and total solar eclipses in 2023 and 2024, engaging over 400 teams with over 3,000 cadets and over 1,000 senior members in every state, Washington DC, and Puerto Rico.
The 2025 Aviation Weather Mission will take place from April through July 2025, collecting observations over two 4-hour periods while practicing additional skills, such as flight tracking, orienteering, and data management. So far, over 3,000 cadets in 46 wings (states) have signed up to participate.
Science Activation recently showed support for this mission through a letter of collaboration sent to CAP Major General Regena Aye in early February. NASA GLOBE Clouds and GLOBE Observer are part of the NASA Earth Science Education Collaborative (NESEC), which is led by the Institute for Global Environmental Strategies (IGES) and supported by NASA under cooperative agreement award number NNX16AE28A. NESEC is part of NASA’s Science Activation Portfolio.

NASA Awards Launch Service for Mission to Study Storm Formation
NASA has selected Firefly Aerospace Inc. of Cedar Park, Texas, to provide the launch service for the agency’s Investigation of Convective Updrafts (INCUS) mission, which aims to understand why, when, and where tropical convective storms form, and why some storms produce extreme weather. The mission will launch on the company’s Alpha rocket from NASA’s Wallops Flight Facility in Virginia.
The selection is part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. This contract allows the agency to make fixed-price indefinite-delivery/indefinite-quantity awards during VADR’s five-year ordering period, with a maximum total value of $300 million across all contracts.
The INCUS mission, comprised of three SmallSats flying in tight coordination, will investigate the evolution of the vertical transport of air and water by convective storms. These storms form when rapidly rising water vapor and air create towering clouds capable of producing rain, hail, and lightning. The more air and water that rise, the greater the risk of extreme weather. Convective storms are a primary source of precipitation and cause of the most severe weather on Earth.
Each satellite will have a high frequency precipitation radar that observes rapid changes in convective cloud depth and intensities. One of the three satellites also will carry a microwave radiometer to provide the spatial content of the larger scale weather observed by the radars. By flying so closely together, the satellites will use the slight differences in when they make observations to apply a novel time-differencing approach to estimate the vertical transport of convective mass.
NASA selected the INCUS mission through the agency’s Earth Venture Mission-3 solicitation and Earth System Science Pathfinder program. The principal investigator for INCUS is Susan van den Heever at Colorado State University in Fort Collins. Several NASA centers support the mission, including Langley Research Center in Hampton, Virginia, the Jet Propulsion Laboratory in Southern California, Goddard Space Flight Center in Greenbelt, Maryland, and Marshall Space Flight Center in Huntsville, Alabama. Key satellite system components will be provided by Blue Canyon Technologies and Tendeg LLC, both in Colorado. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contract.

FARMing with Data: OpenET Launches new Tool for Farmers and Ranchers
6 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Dwane Roth (right), a fourth generation grain farmer in Finney County, Kansas, stands with nephew Zion (left) in one of their corn fields. Roth’s farm became one of the first Water Technology Farms in Kansas around 2016, and he has been using OpenET data for the past few years to track evapotranspiration rates and conserve water. Photo courtesy of Dwane RothA NASA and U.S. Geological Survey (USGS)-supported research and development team is making it easier for farmers and ranchers to manage their water resources.
The team, called OpenET, created the Farm and Ranch Management Support (FARMS) tool, which puts timely, high-resolution water data directly in the hands of individuals and small farm operators. By making the information more accessible, the platform can better support decision-making around agricultural planning, water conservation, and water efficiency. The OpenET team hopes this will help farmers who are working to build greater resiliency in local and regional agriculture communities.
“It’s all about finding new ways to make satellite data easier to access and use for as many people as possible,” said Forrest Melton, the OpenET project scientist at NASA’s Ames Research Center in Silicon Valley. “The goal is to empower users with actionable, science-based data to support decisions about water management across the West.”

OpenET Project Scientist
OpenET Data Explorer Tool: The Road to FARMSThe OpenET data explorer tool centers on providing evapotranspiration data. Evapotranspiration (ET) refers to the amount of water leaving Earth’s surface and returning to the atmosphere through evaporation (from soil and surface water) and transpiration (water vapor released by crops and other plants). Evapotranspiration is an important factor in agriculture, water resource management, irrigation planning, drought monitoring, and fire risk evaluation.
The FARMS resource is the third phase of OpenET’s Data Explorer tool, launched in 2021, which uses satellite data to quantify evapotranspiration across the western U.S.
It starts with using Landsat data to measure patterns in land surface temperature and key indicators of vegetation conditions. The satellite data is combined with agricultural data, such as field boundaries, and weather data, such as air temperature, humidity, solar radiation, wind speed, and precipitation. All of these factors feed into a model, which calculates the final evapotranspiration data.
The new FARMS interface was designed to make that data easier to access, with features that meet specific needs identified by users.
“This amount of data can be complicated to use, so user input helped us shape FARMS,” said Jordan Harding, app developer and interface design leader from HabitatSeven. “It provides a mobile-friendly, map-based web interface designed to make it as easy as possible to get automated, regular reports.”
Top: A section of the 2024 annual report Roth submits to the Farm Service Agency, with hand-written annotations marking which crop will be grown that year. Bottom: Those same fields in the new OpenET FARMS interface, with a dashboard on the left displaying evapotranspiration data over the course of 2024 at monthly intervals. Each color line corresponds to the same color field on the map, showcasing how much evapotranspiration rates can differ between different crops in the same vicinity. The unique shape of the purple field (forage sorghum), is an example of a case where FARMS’ custom shape feature is helpful. Once the initial report is set up, Roth can re-run reports for the same fields at any time. NASA/OpenET“The FARMS tool is designed to help farmers optimize irrigation timing and amounts, simplify planning for the upcoming irrigation season, and automate ET and water use reporting,” said Sara Larsen, CEO of OpenET. “All of this reduces waste, lowers costs, and informs crop planning.”
Although FARMS is geared towards agriculture, the tool has value for other audiences in the western U.S. Land managers who evaluate the impacts of wildfire can use it to evaluate burn scars and changes to local hydrology. Similarly, resource managers can track evapotranspiration changes over time to evaluate the effectiveness of different forest management plans.
New Features in FARMSTo develop FARMS, the OpenET team held listening sessions with farmers, ranchers, and resource managers. One requested function was support for field-to-field comparisons; a feature for planning irrigation needs and identifying problem areas, like where pests or weeds may be impacting crop yields.
The tool includes numerous options for drawing or selecting field boundaries, generating custom reports based on selected models and variables, and automatically re-running reports at daily or monthly intervals.
The fine spatial resolution and long OpenET data record behind FARMS make these features more effective. Many existing global ET data products have a pixel size of over half a mile, which is too big to be practical for most farmers and ranchers. The FARMS interface provides insights at the scale of a quarter-acre per pixel, which offers multiple data points within an individual field.
“If I had told my father about this 15 years ago, he would have called me crazy,” said Dwane Roth, a fourth-generation farmer in Kansas. “Thanks to OpenET, I can now monitor water loss from my crops in real-time. By combining it with data from our soil moisture probes, this tool is enabling us to produce more food with less water. It’s revolutionizing agriculture.”
The FARMS mobile interface displays a six-year evapotranspiration report of a pear orchard owned by sixth-generation California farmer Brett Baker. The purple line in the dashboard report (left) corresponds with the field selected in purple on the map view (right), which users can toggle between using the green buttons in the top right corners. Running multi-year reports allows farmers to review historical trends.NASA/OpenETFor those like sixth-generation California pear farmer Brett Baker, the 25-year span of ET data is part of what makes the tool so valuable. “My family has been farming the same crop on the same piece of ground for over 150 years,” Baker said. “Using FARMS gives us the ability to review historical trends and changes to understand what worked and what didn’t year to year: maybe I need to apply more fertilizer to that field, or better weed control to another. Farmers know their land, and FARMS provides a new tool that will allow us to make better use of land and resources.”
According to Roth, the best feature of the tool is intangible. “Being a farmer is stressful,” Roth said. “OpenET is beneficial for the farm and the agronomic decisions, but I think the best thing it gives me is peace of mind.”

Fourth-Generation Kansas Grain Farmer
Continuing Evolution of FARMSOver the coming months, the OpenET team plans to present the new tool at agricultural conferences and conventions in order to gather feedback from as many users as possible. “We know that there is already a demand for a seven-day forecast of ET, and I’m sure there will be requests about the interface itself,” said OpenET senior software engineer Will Carrara. “We’re definitely looking to the community to help us further refine that platform.”
“I think there are many applications we haven’t even thought of yet,” Baker added. “The FARMS interface isn’t just a tool; it’s an entirely new toolbox itself. I’m excited to see what people do with it.”
FARMS was developed through a public-private collaboration led by NASA, USGS, USDA, the non-profit OpenET, Inc., Desert Research Institute, Environmental Defense Fund, Google Earth Engine, HabitatSeven, California State University Monterey Bay, Chapman University, Cornell University, University of Nebraska-Lincoln, UC Berkeley and other universities, with input from more than 100 stakeholders.

March’s Night Sky Notes: Messier Madness
NASA, ESA and the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration; Acknowledgment: Davide De Martin and Robert Gendler
by Kat Troche of the Astronomical Society of the Pacific
What Are Messier Objects?During the 18th century, astronomer and comet hunter Charles Messier wanted to distinguish the ‘faint fuzzies’ he observed from any potential new comets. As a result, Messier cataloged 110 objects in the night sky, ranging from star clusters to galaxies to nebulae. These items are designated by the letter ‘M’ and a number. For example, the Orion Nebula is Messier 42 or M42, and the Pleiades are Messier 45 or M45. These are among the brightest ‘faint fuzzies’ we can see with modest backyard telescopes and some even with our eyes.
Stargazers can catalog these items on evenings closest to the new moon. Some even go as far as having “Messier Marathons,” setting up their telescopes and binoculars in the darkest skies available to them, from sundown to sunrise, to catch as many as possible. Here are some items to look for this season:
M44 in Cancer and M65 and 66 in Leo can be seen high in the evening sky 60 minutes after sunset. Stellarium WebMessier 44 in Cancer: The Beehive Cluster, also known as Praesepe, is an open star cluster in the heart of the Cancer constellation. Use Pollux in Gemini and Regulus in Leo as guide stars. A pair of binoculars is enough to view this and other open star clusters. If you have a telescope handy, pay a visit two of the three galaxies that form the Leo Triplet – M65 and M66. These items can be seen one hour after sunset in dark skies.
Locate M3 and M87 rising in the east after midnight. Stellarium WebMessier 3 Canes Venatici: M3 is a globular cluster of 500,000 stars. Through a telescope, this object looks like a fuzzy sparkly ball. You can resolve this cluster in an 8-inch telescope in moderate dark skies. You can find this star cluster by using the star Arcturus in the Boötes constellation as a guide.
Messier 87 in Virgo: Located just outside of Markarian’s Chain, M87 is an elliptical galaxy that can be spotted during the late evening hours. While it is not possible to view the supermassive black hole at the core of this galaxy, you can see M87 and several other Messier-labeled galaxies in the Virgo Cluster using a medium-sized telescope.
Locate M76 and M31 setting in the west, 60 minutes after sunset. Stellarium Web Plan AheadWhen gearing up for a long stargazing session, there are several things to remember, such as equipment, location, and provisions:
- Do you have enough layers to be outdoors for several hours? You would be surprised how cold it can get when sitting or standing still behind a telescope!
- Are your batteries fully charged? If your telescope runs on power, be sure to charge everything before you leave home and pack any additional batteries for your cell phone. Most people use their mobile devices for astronomy apps, so their batteries may deplete faster. Cold weather can also impact battery life.
- Determine the apparent magnitude of what you are trying to see and the limiting magnitude of your night sky. You can learn more about apparent and limiting magnitudes with our Check Your Sky Quality with Orion article.
- When choosing a location to observe from, select an area you are familiar with and bring some friends! You can also connect with your local astronomy club to see if they are hosting any Messier Marathons. It’s always great to share the stars!

NASA Successfully Acquires GPS Signals on Moon
NASA and the Italian Space Agency made history on March 3, when the Lunar GNSS Receiver Experiment (LuGRE) became the first technology demonstration to acquire and track Earth-based navigation signals on the Moon’s surface.
The LuGRE payload’s success in lunar orbit and on the surface indicates that signals from the GNSS (Global Navigation Satellite System) can be received and tracked at the Moon. These results mean NASA’s Artemis missions, or other exploration missions, could benefit from these signals to accurately and autonomously determine their position, velocity, and time. This represents a steppingstone to advanced navigation systems and services for the Moon and Mars.

This is a very exciting discovery for lunar navigation, and we hope to leverage this capability for future missions.”

The road to the historic milestone began on March 2 when the Firefly Aerospace’s Blue Ghost lunar lander touched down on the Moon and delivered LuGRE, one of 10 NASA payloads intended to advance lunar science. Soon after landing, LuGRE payload operators at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, began conducting their first science operation on the lunar surface.
Members from NASA and Italian Space Agency watching the Blue Ghost lunar lander touch down on the Moon. NASAWith the receiver data flowing in, anticipation mounted. Could a Moon-based mission acquire and track signals from two GNSS constellations, GPS and Galileo, and use those signals for navigation on the lunar surface?
Then, at 2 a.m. EST on March 3, it was official: LuGRE acquired and tracked signals on the lunar surface for the first time ever and achieved a navigation fix — approximately 225,000 miles away from Earth.
Now that Blue Ghost is on the Moon, the mission will operate for 14 days providing NASA and the Italian Space Agency the opportunity to collect data in a near-continuous mode, leading to additional GNSS milestones. In addition to this record-setting achievement, LuGRE is the first Italian Space Agency developed hardware on the Moon, a milestone for the organization.
The LuGRE payload also broke GNSS records on its journey to the Moon. On Jan. 21, LuGRE surpassed the highest altitude GNSS signal acquisition ever recorded at 209,900 miles from Earth, a record formerly held by NASA’s Magnetospheric Multiscale Mission. Its altitude record continued to climb as LuGRE reached lunar orbit on Feb. 20 — 243,000 miles from Earth. This means that missions in cislunar space, the area of space between Earth and the Moon, could also rely on GNSS signals for navigation fixes.
Firefly’s Blue Ghost lander captured its first sunrise on the Moon, marking the beginning of the lunar day and the start of surface operations in its new home. Firefly AerospaceTraditionally, NASA engineers track spacecraft by using a combination of measurements, including onboard sensors and signals from Earth-based tracking stations. The LuGRE payload demonstrates that using GNSS signals for navigation can reduce reliance on human operators because these signals can be picked up and used autonomously by the spacecraft, even as far away as the Moon.
The LuGRE payload is a collaborative effort between NASA’s Goddard Space Flight Center in Greenbelt, Maryland and the Italian Space Agency. Funding and oversight for the LuGRE payload comes from NASA’s SCaN Program office. It was chosen by NASA as one of 10 funded research and technology demonstrations for delivery to the lunar surface by Firefly Aerospace Inc., a flight under the agency’s Commercial Lunar Payload Services initiative.

On March 2, 1995, space shuttle Endeavour launched from NASA’s Kennedy Space Center in Florida on its eighth trip into space, on the STS-67 Astro-2 mission. The crew included Commander Stephen Oswald, Pilot William Gregory, Mission Specialists John Grunsfeld, Wendy Lawrence, and Tamara Jernigan – who served as payload commander on the mission – and Payload Specialists Samuel Durrance and Ronald Parise. During their then record setting 17-day mission, the astronauts used the three ultraviolet telescopes of the Astro-2 payload to observe hundreds of celestial objects. The mission ended with a landing at Edwards Air Force Base in California.

NASA The STS-67 crew patch. NASA The Astro-2 payload patch.NASAIn August 1993, NASA assigned Jernigan as the payload commander for Astro-2, for a weeklong flight aboard Columbia then targeted for late 1994. Jernigan, selected by NASA in 1985, had previously flown aboard STS-40 and STS-52. Two months later, NASA assigned Grunsfeld, a space rookie from the class of 1992, as a mission specialist. In January 1994, NASA rounded out the crew by assigning Oswald, Gregory, Lawrence, Durrance, and Parise. Oswald, from the class of 1985, had flown previously as pilot on STS-42 and STS-56, while STS-67 represented the first spaceflight for Gregory, selected in 1990, and Lawrence, chosen in 1992. Durrance and Parise, selected as payload specialists in 1984, had flown on STS-35, the Astro-1 mission.

NASA The STS-67 astronauts walk out for their ride to the launch pad. NASAThe Astro-2 science payload consisted of three ultraviolet telescopes mounted on a Spacelab instrument pointing system in the shuttle’s cargo bay. The trio of telescopes flew previously on STS-35, the Astro-1 mission, in December 1990. That mission, originally planned to fly on STS-61E in March 1986, remained grounded following the Challenger accident. Due to equipment malfunctions, the Astro-1 mission only achieved 80% of its objectives, leading to the reflight of the instruments on Astro-2, originally planned as a seven-day mission aboard Discovery. A switch to Columbia enabled a mission twice as long, with significantly more observation time. A scheduled maintenance period for Columbia resulted in Astro-2 switching to Endeavour, with a new flight duration of more than 15 days, but a launch delay to February 1995. The three telescopes supported 23 different studies, observing more than 250 celestial objects including joint observations with the Hubble Space Telescope of the planet Jupiter.

NASAEndeavour returned to Kennedy following its previous flight, STS-68, in October 1994. After servicing the orbiter, workers rolled it to the vehicle assembly building on Feb. 3, 1995, for mating with its external tank and solid rocket boosters, and then out to Launch Pad 39A on Feb. 8. At 1:38 a.m. EST on March 2, Endeavour thundered into the night sky to begin the STS-67 mission. Eight and a half minutes later, the shuttle and its crew had reached space.
Shortly after reaching orbit, the crew opened the payload bay doors and deployed the shuttle’s radiators. Jernigan and Durrance activated the Spacelab pallet and its pointing system and the telescopes. The crew split into two shifts to enable data collection around the clock during the mission. Oswald, Gregory, Grunsfeld, and Parise made up the red shift while Lawrence, Jernigan, and Durrance comprised the blue shift.

The Middeck Active Control Experiment studied the active control of flexible structures in space. Five years later, a newer version flew as one of the first experiments on the International Space Station.

With three other cosmonauts already aboard Mir, the total number of humans in orbit grew to a then-record of 13. Two days later, Oswald and Thagard, who had flown together on STS-42, talked to each other via ship-to-ship radio.
Inclement weather at Kennedy thwarted the planned reentry on March 17, and the astronauts spent an extra day in space. On March 18, they again waved off a Kennedy landing and one orbit later, Oswald and Gregory piloted Endeavour to a smooth landing at Edwards Air Force Base in California. The crew had flown 262 orbits around the Earth in 16 days, 15 hours, and 9 minutes, at the time the longest space shuttle mission. A few hours later, a large crowd greeted the astronauts upon their return to Houston’s Ellington Field. Endeavour began its ferry flight back to Kennedy on March 26, arriving there the next day. Workers towed Endeavour to the processing facility to prepare it for its next flight, STS-73, then planned for September 1995.

X-ray Signal Points to Destroyed Planet, Chandra Finds
A planet may have been destroyed by a white dwarf at the center of a planetary nebula — the first time this has been seen. As described in our latest press release, this would explain a mysterious X-ray signal that astronomers have detected from the Helix Nebula for over 40 years. The Helix is a planetary nebula, a late-stage star like our Sun that has shed its outer layers leaving a small dim star at its center called a white dwarf.
This composite image contains X-rays from Chandra (magenta), optical light data from Hubble (orange, light blue), infrared data from ESO (gold, dark blue), and ultraviolet data from GALEX (purple) of the Helix Nebula. Data from Chandra indicates that this white dwarf has destroyed a very closely orbiting planet.
This artist’s impression shows a planet (left) that has approached too close to a white dwarf (right) and been torn apart by tidal forces from the star. The white dwarf is in the center of a planetary nebula depicted by the blue gas in the background. The planet is part of a planetary system, which includes one planet in the upper left and another in the lower right. The besieged planet could have initially been a considerable distance from the white dwarf but then migrated inwards by interacting with the gravity of other planets in the system.CXC/SAO/M.WeissAn artist’s concept shows a planet (left) that has approached too close to a white dwarf (right) and is being torn apart by tidal forces from the star. The white dwarf is in the center of a planetary nebula depicted by the blue gas in the background. The planet is part of a planetary system, which includes one planet in the upper left and another in the lower right. The besieged planet could have initially been a considerable distance from the white dwarf but then migrated inwards by interacting with the gravity of the other planets in the system.
Eventually debris from the planet will form a disk around the white dwarf and fall onto the star’s surface, creating the mysterious signal in X-rays that astronomers have detected for decades.
Dating back to 1980, X-ray missions, such as the Einstein Observatory and ROSAT telescope, have picked up an unusual reading from the center of the Helix Nebula. They detected highly energetic X-rays coming from the white dwarf at the center of the Helix Nebula named WD 2226-210, located only 650 light-years from Earth. White dwarfs like WD 2226-210 do not typically give off strong X-rays.
In about 5 billion years, our Sun will run out of fuel and expand, possibly engulfing Earth. These end stages of a star’s life can be utterly beautiful as is the case with this planetary nebula called the Helix Nebula.X-ray: NASA/CXC/SAO/Univ Mexico/S. Estrada-Dorado et al.; Ultraviolet: NASA/JPL; Optical: NASA/ESA/STScI (M. Meixner)/NRAO (T.A. Rector); Infrared: ESO/VISTA/J. Emerson; Image Processing: NASA/CXC/SAO/K. Arcand;A new study featuring the data from Chandra and XMM-Newton may finally have settled the question of what is causing these X-rays from WD 2226-210: this X-ray signal could be the debris from a destroyed planet being pulled onto the white dwarf. If confirmed, this would be the first case of a planet seen to be destroyed by the central star in a planetary nebula.
Observations by ROSAT, Chandra, and XMM-Newton between 1992 and 2002 show that the X-ray signal from the white dwarf has remained approximately constant in brightness during that time. The data, however, suggest there may be a subtle, regular change in the X-ray signal every 2.9 hours, providing evidence for the remains of a planet exceptionally close to the white dwarf.
Previously scientists determined that a Neptune-sized planet is in a very close orbit around the white dwarf — completing one revolution in less than three days. The researchers in this latest study conclude that there could have been a planet like Jupiter even closer to the star. The besieged planet could have initially been a considerable distance from the white dwarf but then migrated inwards by interacting with the gravity of other planets in the system. Once it approached close enough to the white dwarf the gravity of the star would have partially or completely torn the planet apart.
WD 2226-210 has some similarities in X-ray behavior to two other white dwarfs that are not inside planetary nebulas. One is possibly pulling material away from a planet companion, but in a more sedate fashion without the planet being quickly destroyed. The other white dwarf is likely dragging material from the vestiges of a planet onto its surface. These three white dwarfs may constitute a new class of variable, or changing, object.
A paper describing these results appears in The Monthly Notices of the Royal Astronomical Society and is available online. The authors of the paper are Sandino Estrada-Dorado (National Autonomous University of Mexico), Martin Guerrero (The Institute of Astrophysics of Andalusia in Spain), Jesús Toala (National Autonomous University of Mexico), Ricardo Maldonado (National Autonomous University of Mexico), Veronica Lora (National Autonomous University of Mexico), Diego Alejandro Vasquez-Torres (National Autonomous University of Mexico), and You-Hua Chu (Academia Sinica in Taiwan).

Visual Description
This release features two images; a composite image of the Helix Nebula, and an artist’s rendering of a planet’s destruction, which may be occurring in the nebula’s core.
The Helix Nebula is a cloud of gas ejected by a dying star, known as a white dwarf. In the composite image, the cloud of gas strongly resembles a creature’s eye. Here, a hazy blue cloud is surrounded by misty, concentric rings of pale yellow, rose pink, and blood orange. Each ring appears dusted with flecks of gold, particularly the outer edges of the eye-shape.
The entire image is speckled with glowing dots in blues, whites, yellows, and purples. At the center of the hazy blue gas cloud, a box has been drawn around some of these dots including a bright white dot with a pink outer ring, and a smaller white dot. The scene which may be unfolding inside this box has been magnified in the artist’s rendering.
The artist’s digital rendering shows a possible cause of the large white dot with the pink outer ring. A brilliant white circle near our upper right shows a white dwarf, the ember of a dying star. At our lower left, in the relative foreground of the rendering, is what remains of a planet. Here, the planet resembles a giant boulder shedding thousands of smaller rocks. These rocks flow off the planet’s surface, pulled back toward the white dwarf in a long, swooping tail. Glowing orange fault lines mar the surface of the crumbling planet. In our upper left and lower right, inside the hazy blue clouds which blanket the rendering, are two other, more distant planets. After the rocks from the planet start striking the surface of the white dwarf, X-rays should be produced.

Sols 4468-4470: A Wintry Mix of Mars Science NASA’s Mars rover Curiosity captured this image showing its wheel awkwardly perched atop one of the rocks in this location, as well as the textures of the layered sulfate unit bedrock blocks. The rover used its Left Navigation Camera (Navcam), one of a pair of stereo cameras on either side of the rover’s masthead, to record the image on Feb. 28, 2025, on sol 4466, or Martian day 4,466 of the Mars Science Laboratory mission, at 00:34:10 UTC. NASA/JPL-CaltechWritten by Lucy Lim, Planetary Scientist at NASA’s Goddard Space Flight Center
Earth planning date: Friday, Feb. 28, 2025
Curiosity continues to climb roughly southward through the layered sulfate strata toward the “boxwork” features. Although the previous plan’s drive successfully advanced the rover roughly 21 meters southward (about 69 feet), the drive had ended with an awkwardly perched wheel. Because of this, unfortunately it was considered too risky to unstow the arm for contact science in this plan.
Nevertheless the team made the most of the imaging and LIBS observations available from the rover’s current location. A large Mastcam mosaic was planned on the nearby Texoli butte to capture its sedimentary structures from the rover’s new perspective. Toward the west, the boxwork strata exposed on “Gould Mesa” were observed using the ChemCam long-distance imaging capability, with Mastcam providing color context.
Several near-field Mastcam mosaics also captured some bedding and diagenetic structure in the nearby blocks as well as some modern aeolian troughs in the finer-grained material around them.
On the nearby blocks, two representative local blocks (“Gabrelino Trail” and “Sespe Creek”) are to be “zapped” with the ChemCam laser to give us LIBS (laser-induced breakdown spectroscopy) compositional measurements. The original Gabrelino Trail on Earth near the JPL campus is currently closed due to damage from the recent wildfires.
Meanwhile, the season on Mars (L_s ~ 50, or a solar longitude of about 50 degrees, heading into southern winter) has brought with it the opportunity to observe some recurring atmospheric phenomena: It’s aphelion cloud belt season, as well as Hadley cell transition season, during which a more southerly air mass crosses over Gale Crater.
This plan includes an APXS atmospheric observation (no arm movement required!) to measure argon and a ChemCam passive-sky observation to measure O2, which is a small (less than 1%) but measurable component in the Martian atmosphere. Dedicated cloud altitude observations, a phase function sky survey, and zenith and suprahorizon movies have also been included in the plan to characterize the clouds. As usual, the rover also continues to monitor the modern environment with measurements of atmospheric opacity via imaging, temperature, and humidity with REMS, and the local neutron environment with DAN.

Interview with Sean Colgan
I’m really pleased that you agreed to take advantage of this opportunity. I don’t recall if I have actually met you personally, but if so, then I apologize for not remembering.
I don’t think so, although you’ve certainly signed things for me.
Well, I guess I have because I do remember seeing your name from time to time on various things. You’ve been at Ames a long time and we’ll have you talk about that in a little bit. The focus of these interviews is not specifically on your work. In fact, it was intended to broaden people’s understanding of who you are and what you do when you’re not at work, because we get compartmentalized and mostly get to know people through our work interactions, so we’ll be touching on your other interests. As you’ve seen if you’ve read some of these, we generally start with your childhood. I try to look up bios and things like that ahead of time to see what I can glean before these interviews but you don’t have a very substantial presence on the web.
I’m not a very public person.
I did find that out (laughs).
I did not volunteer for these and I tried to lay low until you hunted me down! (laughs)
Well, I think you’ll be pleased and as I said, you can stay as private as you want during this whole interview.
Sounds good.
We like to start with where you were born, your family at the time, what your parents did, if you have siblings, and then we ask when became aware of or developed an interest in what you have pursued as a career.
OK, and I’m going to be looking sideways at my notes because I printed out your list of questions and thought about them. Hopefully I won’t mess it up too much. I’m a big believer in the written word. I was born in Oakland, just up the Bay.
So was I, so we have a connection right there!
Up through my preteen years I grew up split between Oakland and North Lake Tahoe. My dad was a masonry contractor. When school got out in June we would go up to Tahoe where there was lots of work for him, building foundations for homes and so forth. When Christmas break came in school, we came back down to Oakland. We had a home in both places and dad could get work in the winter in the Bay Area. In the middle of every year during my preteen years, I switched between two schools. It was usually a bit of a jolt because the Oakland schools were ahead of the Tahoe schools, so there were a couple weeks of flailing about in January trying to catch up. They all used the same textbooks, but we were a couple of chapters behind at that point and had to catch up.
When I was 12, Dad had established his business well enough at Tahoe that my parents sold both of the houses, built a somewhat bigger one, and we moved to Tahoe permanently. So from seventh grade through high school it was all at the northern end of Lake Tahoe.
I have one sibling, a brother.
And when did I start thinking about becoming an astronomer? I can’t remember exactly, to be perfectly honest. I do remember my parents showing me the constellations. I can remember specifically which constellations my dad showed me and which ones my mom showed me. I can’t remember a time when I wasn’t interested primarily in being an astronomer, but I probably went through an astronaut phase because it was the ‘60’s! I got an astronomy book for my birthday one year and I know it was before I could really read and understand it. I remember looking at the pictures. In thinking about this interview, I went back and looked. That book was published when I was five, so probably by the time I was five I was talking about it enough that I got this book for my birthday. I don’t have any similar books on other topics from that time. All the other books I have from back then are astronomy books for kids.
Well, you were living in Lake Tahoe, which by the elevation and the clarity and lack of ambient lights around you would have had a really good view of the stars and constellations.
Right. It was great. Although before we moved up there full time we were mostly there in the summer, so it didn’t get dark until after my bedtime. When we moved up there full time, then I could go out in the winter and yeah, we had a spectacular view of the southern sky. There were woods but we could see over the trees. We could see the center of the Milky Way, and so forth. I had binoculars and a couple of small telescopes that I’d use, along with a star atlas to point me toward interesting things to look at.
Did you say what your mother did? Did she work outside the home?
Mom was a writer. We traveled each year when we were growing up. She would write travelogues of those trips and try to get them published. She also wrote haiku poetry, and she tried her hand at writing other things. She was published a bit, but not a whole lot. Mom did get one of her travelogues published in the Christian Science Monitor. That was a highlight for her.
And was your brother older or younger?
My brother is two years younger, and we had somewhat similar trajectories. We’ll get to education later but he majored in physics as well. He followed me in similar universities, but ended up going into material sciences. He is now on the East Coast working for IBM.
That’s great.
He was named a Master Inventor in 2018.
A what?
A Master Inventor. He has over 200 patents, so IBM honored him with this title.
That’s quite an honor! Your education was interesting because of the split between the two schools. But then at some point, when you went to college, you had to declare a major. You said you had already developed an interest in astronomy, so did you pursue that science discipline right off the bat?
I went to UC Riverside for two years, and then I transferred to Caltech. My freshman year I really nailed down my choice for astronomy. I remember going to the Career Center and taking an interest survey, which has nothing to do with what you’re able to do. It just asks what you’re interested in doing, and it came up as physicist or musician. I have no musical skills so that pointed me in the other direction. I thought briefly about geology, since my dad had been a geology major, but I really settled on astronomy at that point, which is why I transferred. Riverside didn’t have an astronomy major, they only had a physics major. I really wanted to get an astronomy background and start on it early.
My time at Caltech was probably the toughest two years I’ve ever had. I was behind because I had gone to Riverside for two years and the Caltech student body was extremely competitive. Caltech was not generous with their transfer credits. I ended up taking a very heavy course load, but I did make it out in two years. From there I applied to a number of grad schools. I settled on Cornell for a couple reasons: First of all because they had groups working in the areas of astronomy I thought I was interested in, which were radio and infrared. Second of all, after four years in southern California I really wanted to go to a more rural setting to continue my education.
I have to ask this because when we’ve interviewed others who have gone to Cornell, most of them have mentioned the influence of Carl Sagan and I just wondered if that figured into your choice, or was he gone by the time you went there?
Well, I did meet Carl, at a second year reception he threw for the grad students. He was gone most of my first year working on Cosmos the television show. He had taken a leave of absence and wasn’t around. When he came back he threw a reception for all of us, and I got to shake his hand. He was a planetary scientist, of course, and that was not where I was aiming my trajectory. I didn’t see him a whole lot other than that one reception. Although from time to time the kind of people you really don’t want wandering around the halls would come around the building looking for Carl Sagan. Security would chase them down and get them out. These are really my most distinct memories of Carl.
And your PhD was in astronomy, not physics?
It was in astronomy and my dissertation was on radio astronomy. I did it almost exclusively at Arecibo (Arecibo Observatory, National Astronomy and Ionosphere Center, Arecibo, Puerto Rico) with a little bit at the VLA (Very Large Array Radio Telescope facility, near Socorro, New Mexico). I got to work with some really smart people at Cornell, observational and theoretical.
At this point we usually inquire about the connection or the influence, that brought you from your PhD to NASA Ames.
My degree was in radio astronomy but the other interest I always had along the way, which I hadn’t been able to look into, was infrared astronomy. Getting post docs is very competitive, back then we called them NRC’s. The NRC offer from Ed Erickson’s group at Ames was the best offer, so I came out for that. It wasn’t a sure thing, there was back and forth and the highest rated candidate had to turn down the job before they would make me an offer. But fortunately for me the highest rated candidate was my office mate at Cornell. I knew he was going to turn down the offer as soon as he got another one he wanted, so I was aware a little bit in advance of getting the call from Ed that things had worked out.
And Ed was your advisor?
Ed was my advisor. So I came and did two years as an NRC and then continued working with the group. I had made myself sufficiently useful that when I was ready to apply for other jobs, Ed offered me a raise if I’d stay with the group and continue working. That was a really good time. We flew on the KAO (Kuiper Airborne Observatory). They didn’t really have facility instruments, so we had our own instrument, but we did support observers from outside our group. We probably had more flights than any other instrument on the KAO during that period. It was a lot of flights. We had to operate it ourselves. All of us had our own particular jobs on flights. We did everything from prepping for the observations, writing proposals, all the way through to seeing them published. We were a small team: Ed Erickson, Mike Haas; Jan Simpson, and Bob Rubin on the science side helped out. We had a shop guy, Gene Beckstrom, and others after him. We had a lab technician, Jim Baltz. Dave Hollenbach would also work with us, and that was very rewarding. He was a very sharp guy in terms of theory, ideas and projects to do. Here is a photo of some of us with our instrument rack getting ready for a KAO flight:
Sean Colgan with his team on the KAO (Kuiper Airborne Observatory).So you came in on an NRC postdoctoral fellowship in the mid-‘80’s?
Yes, I started on October 6th, 1986.
And your first work was on the KAO and then probably a decade later you continued on SOFIA (Stratospheric Observatory for Infrared Astronomy)?
It was ‘95 or ‘96 when they shut down the KAO to use the funding for SOFIA development. I remember the meeting still. It was in the upstairs auditorium and they came in and announced they were shutting the KAO down. I think it was Dave Morrison, who was the division chief, who told us not to whine about shutting it down because planetary missions sometimes had years when they didn’t have their facilities. In this case it was only going to be two years and we would be up and flying in 1997. Of course, as we know, it was more like ten years after that before we were even close to flying.
Yes, I thought the same thing, that it was not going to be two years. It always takes longer than that.
Well, I don’t think anybody thought it was going to be as many years as it was.
But you flew on both the KAO and SOFIA?
I had ninety nine flights on the Kuiper (KAO) because I kept track of them, and on SOFIA I had two flights, so I was not a flyer on SOFIA. It was more of a facility observatory, and the people who flew a lot were really part of the observatory. They were operating the telescope or operating a science instrument. My flights on SOFIA were because I had written some software for the GREAT Instrument (German Receiver for Astronomy at Terahertz Frequencies, a modular dual-color heterodyne instrument for high-resolution far-infrared spectroscopy) to help them interface with SOFIA. I was along on those commissioning flights for GREAT in case my software broke. They wanted me on board. Interestingly by the rules at the time, I wouldn’t be allowed to actually fix the software in flight because it was flight software and had to go through all the reviews. None of the people who could do the reviews were on the airplane, but I could see how it broke and maybe I could suggest workarounds. It was not nearly as much fun for me as the KAO. I didn’t really have a job. The software had issues from time to time, but it basically worked. Everybody else had jobs, so for me it was less interesting, which is why I didn’t make a huge effort to keep flying on SOFIA.
Did you stay on the SOFIA project as a somewhat non flying support person?
Yes, from when the Kuiper stopped flying until about, well now, my primary work on SOFIA has been first with the project science team during development – trying to make sure they met our requirements, helping everybody understand our requirements, trying to make sure they weren’t making any huge mistakes. They made them anyway, especially when they didn’t listen to us, but we did our best. During the early years of SOFIA, I was also on the Ames team developing AIRES – a facility Science Instrument for SOFIA. I led the software effort, but the development was canceled in 2001. I then got involved with the software that people would use to propose to SOFIA, the proposal software, the software to estimate how long you should be asking for time, the sensitivity of the instruments, pieces of software like that. I worked with Dave Goorvich. We got software from other observatories as starting points and then modified them for SOFIA, software “re-use” they called it. And that was basically my main job throughout SOFIA’s lifetime. Once we developed those, the USRA (Universities Space Research Association) folks built their team around maintaining them and I joined that team because I’d been working on this software for so long. I also got into the package I mentioned to help GREAT interface to SOFIA. It basically made SOFIA look like the telescope that the GREAT team had been using for years, an observatory called KOSMA. We called it the translator and it translated KOSMA commands into SOFIA commands; then SOFIA housekeeping back into KOSMA housekeeping, so they didn’t need to change their software to work with SOFIA. As the aircraft started flying, it became quite clear that I was oversubscribed. I was not meeting my deadlines for either of those two efforts, so I gave up the translator. They hired another fellow to maintain that, although I stayed in touch with it for some years, helping him when he had questions and so forth. I then focused my main effort over on SOFIA’s DCS (Data Cycle System) side.
What has been your most interesting work here at Ames?
I’d say it was flying on the KAO, but very specifically it was Supernova 1987A which occurred after I had been here for only a couple of months. It went off in February of 1987. Nobody really knew what it would look like in the infrared to an instrument on an observatory like the KAO, so it was obviously a huge deal since it was the closest supernova for hundreds of years. Our team just completely redirected to carry out observations of the supernova. Dave Hollenbach and I worked together to try and figure out what we would see. We wrote up the science portion of the proposal,. For these observations, our instrument – the CGS (Cooled-Grating-Spectrometer) – had to be fairly substantially reworked in the sense that the grating needed to be changed to go to lower resolution and the detectors needed to be changed to get wider bandwidth and go to shorter wavelengths. Ed and Mike worked long days, weeks, and months to make all of those changes happen. In our proposal we made some predictions about which lines we could see, mostly iron lines, and which ionization states. We put that in the proposal, which was accepted. We then wrote up the proposal as a separate paper. When we went down and did the observations, we actually got some of it right. Surprisingly, iron was indeed bright. We thought we’d be seeing all different ionized states of iron, from singly, doubly, triply ionized iron, when in fact it was very much concentrated in singly ionized iron with a little bit of doubly ionized iron, there was a faint line there. We had gotten the temperatures right, but we didn’t quite get the ionization right. We were in the ballpark, so I think this was really the most interesting work in that when we started nobody had really seen anything like it before. We were starting from very basic principles, and we followed that all the way through to a nice series of papers. We went down for three different epochs because the lines were changing with time as the supernova ejecta expanded. We obtained three sets of measurements, which resulted in three papers.
What I’m currently working on? Well, SOFIA is, of course, shut down and I am working as part of the shutdown process. We’re trying to reprocess a lot of the data to bring it up to standard, especially the older data. We learned more about the instruments as time went on, so we can now do a better job of reducing the data. I’m helping out with reducing the data, getting it into the archive as we shut down, and of course, writing proposals.
What comes next? So far I’ve collaborated mainly with Naseem, whom you have spoken to, Sarah Nickerson, whom you also have spoken to, and Doug Hoffman (whom we’ve also spoken to). So that’s proposals.
How is your work relevant to Ames and the NASA mission?
Well, I’ve worked on NASA missions almost my entire career, so I think that’s the closest to relevance as you can get.
What is a typical day like for you?
I mostly work, well before the pandemic in my office, but now it’s back and forth. I do like to come into the office although this week is a little different. That’s why we’re doing this interview from home. My wife is out of town and I like to work at home on those weeks just to keep the dog out of trouble. So I’m at a computer. I’m a software guy and a data analysis guy, not a lab guy, so I work at the computer. I actually have several computers on my desk. I look like a real developer (laughs). If you see my desk, I’ve got a couple of big screens and couple of computers underneath hooked up to different things and I can switch them around. So that’s a typical day, but at home it’s a little tougher. I don’t have a desk that can really manage the big screens, so I’ve just got one little laptop screen to work with.
Is home close enough that the pandemic shut down of the Center didn’t really save you a whole lot of commute time?
I live across the Bay in Newark, which physically is not far, but traffic wise is not good. I typically come in later and stay later because that works with my wife’s schedule and also works with the traffic. We’re not so close that it’s easy. I hated during the pandemic having to work at home all the time because of the small screen and with no room to spread out piles of paper or stay organized. That was definitely a challenge. I was very glad to get back on site.
What do you like most and least about your job?
Most would be doing science, but I also enjoy coding. Least is probably the standard sorts of things that most people whine about when given any opportunity. All the stuff that goes with the job that isn’t science or coding, like IT security and paperwork. Right now I’m in the midst of training, taking courses I’ve taken every year for the last ten years, which gets a little old after a while, things like that. But somebody thinks you need to do it, and I hope it makes us a better organization for everybody doing it.
Do you have a favorite memory from your career? Or perhaps a research finding or breakthrough, or an unexpected research result?
My favorite memory would be the Supernova 1987A work in general. We found some unexpected things there and we got some things right.
If you could have a dream job, what would it be?
My dream job is pretty close to what I have. Pretty close without all the extra stuff.
What advice would you give to someone who wants a career like yours?
Of course you’ve got to work hard, and you need to have an aptitude for it. It’s a very competitive field, so you’ve also got to realize that luck, or being in the right place at the right time, can be a factor in whether you continue or not. I’ve had colleagues who were very good at what they do, but they just weren’t in the right place at the right time. They ended up leaving the field or doing something less than what they hoped. Some things are just out of your control.
I did get lucky. I was in the right place at the right time. I flew on the Kuiper, and I developed skills. When SOFIA started, those skills were very much in demand. That was my right place, right time moment, which is when I joined the civil service. I had been a contractor after my NRC ended through 1997. I became a civil servant then because there was so much work on SOFIA. I don’t know if that’s helpful advice, but it’s just my take on things.
Well, you’re right. There’s something to being in the right place, at the right time and being prepared, but there’s always the serendipity aspect, which is just part of life. You could have wound up somewhere else and been just as happy, you know.
Oh yes, It doesn’t necessarily relate to happiness, but you’ve got to make the best with what you have. I do feel lucky about that.
Would you like to share anything about your family? Kids, pets, activities? You mentioned a dog?
I’m going to mix the order up a little bit.
Sure, go ahead.
The accomplishment I’m most proud of that’s not science related would be 40 years of marriage to my fabulous wife. We just celebrated our 40th anniversary about a week and a half ago.
Congratulations! That is indeed an accomplishment.
So, no children but we do have a dog, a little Welsh Corgi. She’s our second corgi and she is just great. We do enjoy traveling. Typically, we’ll go on vacation in August. often to Europe. We’ve visited the UK five or six times, France a couple of times, Italy a couple of times. My father-in-law was born in Hungary, so we’ve gone there a couple times. Here is a photo of us at Lake Louise in 2019, with our Corgi.
Sean Colgan with his wife and Corgi at Lake Louise in 2019What do we do for fun the rest of the time? Besides leisure travel, I enjoy gardening. We also enjoy musical events. We have season tickets to the San Jose Opera, for example, and we’ll go up to San Francisco for concerts a couple of times a year. We probably have an event every other month. During the pandemic, the restaurants and movie theaters were closed, but wineries with outdoor spaces were open. They started serving food during the pandemic, and they allowed dogs, so we got in the habit of doing a lot of wine tasting on weekends just to get out. We still do some of that. To celebrate our 40th, we went up to Napa and tasted a lot of great wines. (laughs)
You mentioned that you’re not particularly musical, so you don’t play an instrument or anything, but you enjoy music and opera.
I enjoy listening to music. I played instruments as a child but had no particular talent for it, so. . . .
Do you like to read? And if so, any particular genre?
I read a fair bit, and it’s sort of divided. For entertainment, I’ll read fantasy and science fiction, but when we go on our trips, I’m always buying books about what we’re doing. For example, if we go to France and visit cathedrals, I’ll buy books about how they built cathedrals; or in England I’ll read about old Stone Age tombs. Everybody’s heard about Stonehenge, but there are stone circles and other stacks of stones, big ones, all over the landscape, so I will buy books and read about them. I have books about Roman battle tactics, etc. Oh yes, and I also have a lot of geology books, depending on where we go. When we went to the Canadian Rockies, I got a lot of geology books about that locale. I bring those home, stack them up, and read them, hopefully before the next trip. So yes, a lot of reading. When my wife travels, sometimes I’ll go hiking. She’s gone up to 15-20 weekends a year She’s a textile artist.She teaches lacemaking, which is the way they used to make lace by hand, before machines. There are groups around the country that enjoy lacemaking, so she travels to teach workshops for them on weekends.
Wow, that’s fascinating!
This week, she’s actually up in Sparks, next to Reno, where the National Convention is going on. It moves around every year, but this year it’s relatively close. She travels a lot for that, which keeps her busy. When she’s away, our dog and I will sometimes go for hikes, if we don’t have too much other stuff to do. Interestingly, we are not the only astronomer-lacemaker couple in the world (laughs). There’s an Australian couple – Ron and Jay Ekers – with Jay a lacemaker and Ron an astronomer. We had dinner with them once when they were visiting in the Bay Area because our wives knew each other. My wife had once traveled down to teach in Australia. Normally she just travels around the U.S., but she has done some international trips.
Now, is this manual lacemaking with needles and thread or . . . ?
There can be needles and thread. That’s one form of it. What my wife teaches is “bobbin lace”, which is made on a pillow usually stuffed with straw. Two bobbins are connected by a thread with many of these pairs used to weave threads together to create the pattern. Photos of Louise’s designs are on her website – https://colganlacestudio.com/. Here’s a photo of what a lace pillow looks like.
“Bobbin lace”, which is made on a pillow usually stuffed with straw. Two bobbins are connected by a thread with many of these pairs used to weave threads together to create the patternInteresting. And when did she get interested in this? Was it something she learned as a child, from her mother or grandmother?
No, it was at Cornell. She was in grad school there, which is where we met.
And what was her course of study?
She was in a Master’s program for historic preservation, basically how to preserve old buildings, of which there are many in upstate New York and few in the Bay Area. She had finished her class work, and I still had several years to go on my dissertation. She looked around for something to fill her time, and one of her friends – a colleague in her department – had already taken this up, and brought her to a meeting. She started taking classes from a local teacher, and by the time we moved west, she was well-versed. Not many people out here knew how to do it, so she started taking on students.
So I’m calculating back, since I’m a numbers guy, that if you just celebrated your 40th anniversary, then you must have married her while you were still in grad school?
Yes, about halfway through grad school, in 1983.
Interesting. So you’re a little bit responsible for her developing this interest in lacemaking?
I wouldn’t claim any of that.
But you’re responsible for giving her the time to develop this interest in lacemaking that she has done so well in.
It was all her effort. If anything, I made conditions difficult for her, and she found her way out (laughs). That’s probably the way I would phrase it.
Fair enough. But it’s very interesting. I like when we can poke around a little bit and find out interesting things, because then people who read this will say, “Well, I didn’t know that he went there or that his wife does lacemaking or the other things that you’ve talked about. That’s part of the purpose of these interviews. Who or what inspires you?
That was a real easy one for me: the night sky. It’s not so great in the Bay Area most times, but there’s so much going on up there. I mean, it’s really all laid out for you. Since I studied and read about a lot about the sky as a kid, I know my way around it. a I also know fun little facts, so that’s entertaining to recall as well. When you get up in the mountains, of course it’s just beautiful.
I feel the same way. I don’t see how anyone can look up at and ponder the night sky and not be just fascinated by it. The questions that come up about what it is, how it came to be, what its purpose is, if there is one, and all of that is just fascinating.
Yes, I agree.
Do you have a favorite image, of space or anything that is particularly meaningful to you?
You know I don’t have one now. I mean, there are a lot of very nice ones out there. A big favorite I remember as a kid was a photo of H and Chi Persei, which is a double cluster of stars, not globular clusters but open clusters. It’s very colorful, with red stars and white stars and blue stars in the image – and just imagining it so far away, but these particular stars are so close together. I don’t know much about it, but something about it just impressed me. A photo like what I remember is at https://www.astrobin.com/337742/.
The reason we ask about images is because we like to include them in the post, especially about things you’ve talked about. You mentioned for example, the Supernova 1987A. If a picture from SOFIA came out of that it would be a great addition to this interview. And then maybe you have a picture of you and the corgi on a hike, or your wife doing lace work, anything like that would be great.
Well, we’ll work on that.
[Photo thoughts: The three of us from Lake Louise, link to H & Chi Persei photo on the web, Lace Pillow showing bobbins]
That would be for when you return it after editing. By the way the transcript is a living document so you can make changes right on it and that’s how it will go in. It isn’t all that formal, we’re not tracking edits or anything like that. We’ll add your pictures and get to a point where it’s set up as it would be when it gets posted and then we’ll send it to you for a final check. We’re also several months out in terms of the queue of those that are going to be posted, so it won’t be immediate.
Good.
We’ve posted about 50 of these, but we’ve done another 20 that are in various stages of being made ready. We’ve sent them out but haven’t gotten them back yet because everybody’s so busy. We do have a last question and that is do you have a favorite quote? One that you find meaningful, or witty, or clever, that kind of thing?
I did think about it. Sometimes you asked the question in the online ones about inspirational quotes and this is definitely not inspirational.
It doesn’t have to be.
I was hoping that because you didn’t say it here. My favorite quote is one my mom said a lot when I was growing up. She always attributed it to her father. I actually looked it up on the web, because I would have thought Mark Twain perhaps said it. It doesn’t seem that anybody famous has said it though. The reference is in a book from just ten years ago. The quote is: “The reward for good work is more work.”
Ah, I like that. That’s clever and witty and seems to be true.
Right.
One of my favorite quotes which I don’t think I put into my post because there’s so many of them is from Mike Griffin, former NASA Administrator. He was talking with the press, I think about risk management and why we do things that don’t always work out. He was explaining that there’s always a risk, and if you don’t accept the risk, then you don’t make progress, but they kept questioning him and pushing back on that idea. And he said, “I can explain it to you, but I can’t understand it for you.” And I thought, that’s a good line!
Anyway, you ran the table here on the questions and I appreciate that you prepared ahead of time and wrote some notes down, which made the interview go very well.
As I said, I prefer the written word. I’m not as good at thinking on my feet.
Is there something that you wish we had asked or had put down as a topic that we didn’t, that you would like to add here? And you can certainly add or change anything when we send this back. There’s a note on the transcript that you have full creative control. So if you wanted to say something but didn’t, you can type in an entire extra paragraph or extra question, or remove and cut out an entire section.
And with that, I’ll take the recording and start putting it on a paper and within a couple of weeks, I’ll send you the initial draft and then you can do with it as you wish and send any pictures or anything that relate to things that you talked about and then we’ll get it ready and put it in the queue and eventually you’ll get perhaps a few of your entitled 15 minutes of fame when this goes up. I will add that it goes up on the public side of the of the website so that your family or your friends, anybody can access it and read it.
So if somebody googles names of interviews you’ve done, the links to the interviews come up.
Well, I hope that doesn’t cause you heartburn.
I’ve thought about that as I was phrasing my answers, and changed some passwords so I can include names in the photo captions
I hadn’t thought of that aspect of it, but you’re probably right.
Yeah.
I never know what’s going to touch someone’s concerns.
Well, just to be careful.
(Mark) There’s another thing that even after we publish, we can still edit them years into the future. Everything on the main sites can be changed at any given moment. Also, Fred, just to note, our interviews rank pretty high on the Google rankings. Usually when you Google someone’s name and then NASA, our interviews are near the top of their results, like on the first screen that comes up.
(Fred) Oh, really? I didn’t know that.
(Mark) Yeah. This is a pretty good series, people check it out a lot.
Which means that people googling names are clicking on the interviews and reading them.
(Mark) People read these a lot.
(Fred) The other series I do for the website is “Interesting Fact of the Month”. Steve Howell suggested that would be a nice addition as we try to attract traffic to the website, and I heard a year or so ago that it was the top item on the code ST website, it got the most hits.
(Mark) Yes, you’ve got spots one and two on your side projects!
(Fred) Well, Sean, I appreciate that you were able to overcome your initial hesitation and take the time to work with us on this and I think you’ll be pleased with how it comes out. Thank you very much for being so organized.
Thank you for your time.

University High Knows the Answers at NASA JPL Regional Science Bowl
3 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) A team from University High School of Irvine, California, won the 2025 regional Science Bowl at NASA’s Jet Propulsion Laboratory on March 1. From left, co-coach Nick Brighton, sophomores Shloke Kamat and Timothy Chen, juniors Feodor Yevtushenko and Angelina Yan, senior Sara Yu, and coach David Knight.NASA/JPL-CaltechIn a fast-paced competition, students showcased their knowledge across a wide range of science and math topics.
What is the molecular geometry of sulfur tetrafluoride? Which layer of the Sun is thickest? What is the average of the first 10 prime numbers? If you answered “see-saw,” “radiation zone,” and “12.9,” respectively, then you know a tiny fraction of what high school students must learn to compete successfully in the National Science Bowl.
On Saturday, March 1, students from University High School in Irvine answered enough of these kind of challenging questions correctly to earn the points to defeat 19 other high school teams, winning a regional Science Bowl competition hosted by NASA’s Jet Propulsion Laboratory in Southern California. Troy High, from Fullerton, won second place, while Arcadia High placed third.
Some 100 students gathered at JPL for the fast-paced event, which drew schools from across Los Angeles, Orange, and San Bernardino counties. Teams are composed of four students and one alternate, with a teacher serving as coach. Two teams at a time face off in a round robin tournament, followed by tie-breaker and double-elimination rounds, then final matches.
Students, coaches, and volunteers gathered on March 1 for the annual regional Science Bowl competition held at JPL, which has hosted the event since 1993.NASA/JPL-CaltechThe questions — in biology, chemistry, Earth and space science, energy, mathematics, and physics — are at a college first-year level. Students spend months preparing, studying, quizzing each other, and practicing with “Jeopardy!”-style buzzers.
It was the third year in a row for a University victory at the JPL-hosted event, and the championship round with Troy was a nail-biter until the very last question. The University team only had one returning student from the previous year’s team, junior Feodor Yevtushenko. Both he and longtime team coach and science teacher David Knight said the key to success is specialization — with each student focusing on particular topic areas.
“I wake up and grind math before school,” Feodor said. “Being a jack-of-all-trades means you’re a jack-of-no-trades. You need ruthless precision and ruthless speed.”
University also won for four years in row from 2018 to 2021. The school’s victory this year enables its team to travel to Washington in late April and vie for ultimate dominance alongside other regional event winners in the national finals.
More than 10,000 students compete in some 115 regional events held across the country. Managed by the U.S. Department of Energy, the National Science Bowl was created in 1991 to make math and science fun for students, and to encourage them to pursue careers in those fields. It’s one of the largest academic competitions in the United States.
JPL’s Public Services Office coordinates the regional contest with the help of volunteers from laboratory staff and former Science Bowl participants in the local community. This year marked JPL’s 33rd hosting the event.

NACA Test Pilot Poses with Plane
In this 1957 photo, George Cooper, a test pilot for the National Advisory Committee for Aeronautics, or NACA, stands next to a North American F-100, a supersonic fighter tested by the NACA. Cooper served as a pilot in World War II before being hired at the NACA’s Ames Aeronautical Laboratory in 1945. Between 1945 and his retirement in 1973, Cooper tested over 135 aircraft, routinely pushing them to their limits.
On March 3, 1915, the NACA was established by Congress to “supervise and direct the scientific study of the problems of flight, with a view to their practical solution.” Over the course of its 43 years, the NACA became home to many of the nation’s best and brightest aeronautical engineers and world-class facilities. America’s flight capabilities for military and commercial uses were advanced through its cutting-edge research. It was upon this foundation that America’s civilian space agency was built. With the passing of the Space Act in 1958, the NACA was transformed into NASA and tasked with researching problems of flight in both the air and in space.
Celebrate the 110th anniversary of the founding of the NACA with a new video series.

For more than 24 years, astronauts have continuously lived and worked aboard the space station, testing technologies, performing science, and developing skills needed to explore farther from Earth. Astronauts aboard the orbiting laboratory communicate with NASA’s Mission Control Center in Houston 24 hours a day through SCaN’s (Space Communications and Navigation) Near Space Network.
Important research and technology investigations taking place aboard the space station benefit people on Earth and lays the groundwork for other agency missions. As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars, inspiring Artemis Generation explorers and ensuring the United States continues to lead in space exploration and discovery.

Preventing biofilm formation in space
Ashley Keeley, University of Idaho, holds an anti-bacterial coating sample.University of Idaho Student Payload Opportunity with Citizen Science TeamTwo anti-microbial coatings reduced formation of biofilms in microgravity and have potential for use in space. Controlling biofilms could help protect human health and prevent corrosion and degradation of equipment on future long-duration space missions.
Biofilms, communities of microorganisms that attach to a surface, can damage mechanical systems and present a risk of disease transmission. Bacteria Resistant Polymers in Space examined how microgravity affects polymer materials designed to prevent or reduce biofilm formation. Better anti-fouling coatings also could reduce disease transmission on Earth.
Evaluating organ changes in lunar gravity
Set up for the Mouse Epigenetics experiment aboard the International Space Station. NASAResearchers found different changes in gene expression and other responses to simulated lunar gravity levels in specific organs. This finding could help determine safe gravity thresholds and support development of ways to maintain skeletal and immune function on future space journeys.
Spaceflight can affect skeletal and immune system function, but the molecular mechanisms of these changes are not clear. Mouse Epigenetics, a JAXA (Japan Aerospace Exploration Agency) investigation, studied gene expression changes in mice that spent a month in space and in the DNA of their offspring. Results could help determine spaceflight’s long-term effects on genetic activity, including changes within individual organs and those that can be inherited later.
Performance report for cosmic ray observatory
The CALorimetric Electron Telescope instrument is visible on the far left of the space station’s Kibo laboratory module. JAXA (Japanese Aerospace Exploration Agency)/Norishige KanaiResearchers report on-orbit performance from the first 8 years of operation of the International Space Station’s cosmic ray observatory, CALET. The instrument has provided valuable data on cosmic ray, proton, and helium spectra; produced a gamma-ray sky map; observed gamma-ray bursts; and searched for gravitational wave counterparts and solar effects.
The JAXA CALorimetric Electron Telescope or CALET helps address questions such as the origin and acceleration of cosmic rays and the existence of dark matter and nearby cosmic-ray sources. The instrument also could help characterize risks from the radiation environment that humans and electronics experience in space.
