A total solar eclipse creates stunning celestial views for people within the path of the Moon’s shadow. This astronomical event is a unique opportunity for scientists to study the Sun and its influence on Earth, but it’s also a perfect opportunity to capture unforgettable images. Whether you’re an amateur photographer or a selfie master, try out these tips for photographing the eclipse.  

A total solar eclipse is a unique opportunity for scientists studying in the shadow of the Moon, but it’s also a perfect opportunity to capture unforgettable images. Whether you’re an amateur photographer or a selfie master, try out these tips for photographing the eclipse.

#1 – Safety First

Looking directly at the Sun is dangerous to your eyes and your camera. To take images when the Sun is partially eclipsed, you’ll need to use a special solar filter to protect your camera, just as you’ll need a pair of solar viewing glasses (also called eclipse glasses) to protect your eyes. However, at totality, when the Moon completely blocks the Sun, make sure to remove the filter so you can see the Sun’s outer atmosphere – the corona.

#2 – Any Camera Is a Good Camera

Taking a stunning photo has more to do with the photographer than the camera. Whether you have a high-end DLSR or a camera phone, you can take great photos during the eclipse; after all, the best piece of equipment you can have is a good eye and a vision for the image you want to create. If you don’t have a telephoto zoom lens, focus on taking landscape shots and capture the changing environment.

Having a few other pieces of equipment can also come in handy during the eclipse. Using a tripod can help you stabilize the camera and avoid taking blurry images when there is low lighting. Additionally, using a delayed shutter release timer will allow you to snap shots without jiggling the camera.

#3 – Look Up, Down, All Around

While the Sun is the most commanding element of a solar eclipse, remember to look around you. As the Moon slips in front of the Sun, the landscape will be bathed in eerie lighting and shadows. As light filters through the overlapping leaves of trees, it creates natural pinholes that project miniature eclipse replicas on the ground. Anywhere you can point your camera can yield exceptional imagery, so be sure to compose some wide-angle photos that can capture your eclipse experience.

NASA photographer Bill Ingalls recommends focusing on the human experience of watching the eclipse. “The real pictures are going to be of the people around you pointing, gawking, and watching it,” Ingalls noted. “Those are going to be some great moments to capture to show the emotion of the whole thing.”

#4 – Practice

Be sure you know the capabilities of your camera before eclipse day. Most cameras, and even some camera phones, have adjustable exposures, which can help you darken or lighten your image during the tricky eclipse lighting. Make sure you know how to manually focus the camera for crisp shots.

For DSLR cameras, the best way to determine the correct exposure is to test settings on the uneclipsed Sun beforehand. Using a fixed aperture of f/8 to f/16, try shutter speeds between 1/1000 to 1/4 second to find the optimal setting, which you can then use to take images during the partial stages of the eclipse. During totality, the corona has a wide range of brightness, so it’s best to use a fixed aperture and a range of exposures from approximately 1/1000 to 1 second.

#5 – Share!

Share your eclipse experience with friends and family afterwards. Tag @NASA to connect your photos on social media to those taken around the country and share them with NASA.

While you’re snapping those eclipse photos, don’t forget to stop and look at the eclipse with your own eyes. Just remember to wear your solar viewing glasses (also called eclipse glasses) for all stages of the eclipse before and after totality!

NASA’s Hubble Finds that Aging Brown Dwarfs Grow Lonely

NASA’s Hubble Finds that Aging Brown Dwarfs Grow Lonely

It takes two to tango, but in the case of brown dwarfs that were once paired as binary systems, that relationship doesn’t last for very long, according to a recent survey from NASA’s Hubble Space Telescope.

Brown dwarfs are interstellar objects larger than Jupiter but smaller than the lowest-mass stars. They are born like stars – out of a cloud of gas and dust that collapses – but do not have enough mass to sustain the fusion of hydrogen like a normal star.

This is an artist’s concept of a brown dwarf. This class of object is too large to be a planet (and did not form in the same way), but is too small to be a star because it cannot sustain nuclear fusion, since it is less massive than even the smallest stars. A brown dwarf is marked by wind-driven horizontal bands of thick clouds that may alternate with relatively cloud-free bands, giving the object a striped appearance. Whirling storm systems as big as terrestrial continents, or even small planets, might exist.

The name “brown dwarf” is a misnomer because the object would typically appear red to the naked eye. It is brightest in infrared light. Many brown dwarfs have binary companions. But as they age, the binary system gravitationally falls apart, and each dwarf goes its separate way, according to a recent Hubble Space Telescope study.

The background stars in this illustration are a science visualization assembled from the Gaia spacecraft star catalog. The synthesized stars are accurate in terms of position, brightness, and color. Because this is not an image of the Milky Way, missing are glowing nebulae and dark dust clouds.

NASA, ESA, Joseph Olmsted (STScI)

Astronomers using Hubble confirm that companions are extremely rare around the lowest-mass and coldest brown dwarfs. Hubble can detect binaries as close to each other as a 300-million-mile separation – the approximate separation between our Sun and the asteroid belt. But they didn’t find any binary pairs in a sample of  brown dwarfs in the solar neighborhood. This implies that a binary pair of dwarfs is so weakly linked by gravity that they drift apart over a few hundred million years due to the pull of bypassing stars.

“Our survey confirms that widely separated companions are extremely rare among the lowest-mass and coldest isolated brown dwarfs, even though binary brown dwarfs are observed at younger ages. This suggests that such systems do not survive over time,” said lead author Clémence Fontanive of the Trottier Institute for Research on Exoplanets, Université de Montréal, Canada.

In a similar survey Fontanive conducted a couple of years ago, Hubble looked at extremely young brown dwarfs and some had binary companions, confirming that star-forming mechanisms do produce binary pairs among low-mass brown dwarfs. The lack of binary companions for older brown dwarfs suggests that some may have started out as binaries, but parted ways over time.

The new Hubble findings, published in The Monthly Notices of the Royal Astronomical Society, further support the theory that brown dwarfs are born the same way as stars, through the gravitational collapse of a cloud of molecular hydrogen. The difference being that they do not have enough mass to sustain nuclear fusion of hydrogen for generating energy, whereas stars do. More than half of the stars in our galaxy have a companion star that resulted from these formation processes, with more massive stars more commonly found in binary systems. “The motivation for the study was really to see how low in mass the trends seen among multiple stars systems hold up,” said Fontanive.

“Our Hubble survey offers direct evidence that these binaries that we observe when they’re young are unlikely to survive to old ages, they’re likely going to get disrupted. When they’re young, they’re part of a molecular cloud, and then as they age the cloud disperses. As that happens, things start moving around and stars pass by each other. Because brown dwarfs are so light, the gravitational hold tying wide binary pairs is very weak, and bypassing stars can easily tear these binaries apart,” said Fontanive.

The team selected a sample of brown dwarfs previously identified by NASA’s Wide-Field Infrared Survey Explorer. It sampled some of the coldest and lowest-mass old brown dwarfs in the solar neighborhood. These old brown dwarfs are so cool (a few hundred degrees warmer than Jupiter in most cases) that their atmospheres contain water vapor that condensed out.

To find the coolest companions, the team used two different near-infrared filters, one in which cold brown dwarfs are bright, and another covering specific wavelengths where they appear very faint due to water absorption in their atmospheres.  

“This is the best observational evidence to date that brown dwarf pairs drift apart over time,” said Fontanive. “We could not have done this kind of survey and confirmed earlier models without Hubble’s sharp vision and sensitivity.”

The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. Goddard also conducts mission operations with Lockheed Martin Space based in Denver, Colorado. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

The Marshall Star for March 20, 2024

NASA - Breaking News - Wed, 03/20/2024 - 3:59pm
22 Min Read The Marshall Star for March 20, 2024 Marshall Technologist Talks Solar Sail Technology in Rocket Center Exhibit

By Jessica Barnett

Space enthusiasts at the U.S. Space & Rocket Center were treated to a special exhibit featuring technologist Les Johnson of NASA’s Marshall Space Flight Center and a look at the future of solar sail technology.

NASA technologist Les Johnson, on stage, discusses how the solar sail can use solar propulsion to travel farther in space than anyone has traveled before during an exhibit held March 12 at the U.S. Space & Rocket Center. NASA/Charles Beason

Johnson shared the latest updates on the solar sail technology through brief presentations onstage in the Rocket Center’s atrium as well as one-on-one interactions with museum guests at the various displays set up near the stage. He discussed how the technology will work, showed a video of the solar sail team testing one of the sail’s four quadrants, and discussed what it could mean for the future of space exploration.

“I’m excited about this type of propulsion, because it’s free, it doesn’t run out of fuel, and you can use it to do amazing things in the future,” Johnson said. “We could build really big sails – 10 to 100 times bigger than the Solar Cruiser sail – and instead of using sunlight, we could shine lasers on it and go out in the solar system, literally where we’ve never been before.”

NASA continues to unfurl plans for solar sail technology as a promising method of deep space transportation. The agency cleared a key technology milestone in January with one of four identical solar sail quadrants successfully deploying. Together, the solar sail quadrants will make up the 17,800-square-foot sail.

Marshall leads the solar sail team, which includes Florida-based Redwire Corporation as prime contractor and Huntsville-based NeXolve as subcontractor.

Barnett, a Media Fusion employee, supports the Marshall Office of Communications.

NASA Lights ‘Beacon’ on Moon with Autonomous Navigation System Test

By Rick Smith

For 30 total minutes in February, NASA lit a beacon on the Moon – successfully testing a sophisticated positioning system that will make it safer for Artemis-era explorers to visit and establish a permanent human presence on the lunar surface.

Evan Anzalone, at lower left, principal investigator for the Lunar Node-1 demonstrator payload, monitors the LN-1 mission from the Lunar Utilization Control Area in the Huntsville Operations Support Center at NASA’s Marshall Space Flight Center. LN-1 successfully tested an autonomous navigation and geo-positioning system that will make Artemis-era lunar explorers safer as they work to establish a permanent human presence on the lunar surface.NASA

The Lunar Node 1 demonstrator, or LN-1, is an autonomous navigation system intended to provide a real-time, point-to-point communications network on the Moon. The system – tested during Intuitive Machines’ IM-1 mission as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative – could link orbiters, landers, and even individual astronauts on the surface, digitally verifying each explorer’s position relative to other networked spacecraft, ground stations, or rovers on the move.

That system would be a marked improvement over conventional, Earth-based radio data relays, NASA researchers said – even more so compared to Apollo-era astronauts trying to “eyeball” distance and direction on the vast, mostly grey lunar surface.

“We’ve lit a temporary beacon on the lunar shore,” said Evan Anzalone, LN-1 principal investigator at NASA’s Marshall Space Flight Center. “Now, we seek to deliver a sustainable local network – a series of lighthouses that point the way for spacecraft and ground crews to safely, confidently spread out and explore.”

The experiment was launched Feb. 15 as a payload on the IM-1 mission. The Nova-C lander, named Odysseus, successfully touched down Feb. 22 near Malapert A, a lunar impact crater near the Moon’s South Pole region, executing the first American commercial uncrewed landing on the Moon. The lander spent its subsequent days on the surface conducting six science and technology demonstrations, among them LN-1, before it officially powered down on Feb. 29.

“This feat from Intuitive Machines, SpaceX, and NASA demonstrates the promise of American leadership in space and the power of commercial partnerships under NASA’s CLPS initiative,” NASA Administrator Bill Nelson said in a statement after the landing. “Further, this success opens the door for new voyages under Artemis to send astronauts to the Moon, then on to Mars.” 

During IM-1’s translunar journey, the Marshall team conducted daily tests of the LN-1 beacon. The original plan was for the payload to transmit its beacon around the clock upon landing. NASA’s Deep Space Networkthe international giant radio antenna array, would have received that signal for, on average, 10 hours daily.

Instead, due to the lander’s touchdown orientation, LN-1 conducted two 15-minute transmissions from the surface. DSN assets successfully locked on the signal, feeding telemetry, navigation measurements, and other data to researchers at Marshall, NASA’s Jet Propulsion Laboratory, and Morehead State University in Morehead, Kentucky. The team continues to evaluate the data.

LN-1 even provided critical backup to IM-1’s onboard navigation system, noted Dr. Susan Lederer, CLPS project scientist at NASA’s Johnson Space Center. The LN-1 team “really stepped up to the task,” she said, by relaying spacecraft positioning data during translunar flight to NASA’s Deep Space Network satellites at the Goldstone and Madrid Deep Space Communications Complexes in Fort Irwin, California, and Robledo de Chavela, Spain, respectively.

Taken on Feb. 27, Odysseus captured an image using its narrow-field-of-view camera.Intuitive Machines

In time, navigation aids such as Lunar Node-1 could be used to augment navigation and communication relays and surface nodes, providing increased robustness and capability to a variety of users in orbit and on the surface.

As the lunar infrastructure expands, Anzalone envisions LN-1 evolving into something akin to a network that monitors and maintains a busy metropolitan subway system, tracking every “train” in real time, and operating as one part of a larger, LunaNet-compatible architecture, augmenting other NASA and international investments, including the Japanese Aerospace Exploration Agency’s Lunar Navigation Satellite System.

And the technology promises even greater value to NASA’s Moon to Mars efforts, he said. LN-1 may improve data delivery to lunar explorers by just a matter of seconds over conventional relays – but real-time navigation and positioning becomes much more vital on Mars, where transmission delays from Earth can take up to 20 minutes.

“That’s a very long time to wait for a spacecraft pilot making a precision orbital adjustment, or humans traversing uncharted Martian landscapes,” Anzalone said. “LN-1 can make lighthouse beacons of every explorer, vehicle, temporary or long-term camp, and site of interest we send to the Moon and to Mars.”

Marshall engineers designed, developed, integrated, and tested LN-1 as part of the NPLP (NASA-Provided Lunar Payloads) project funded by the agency’s Science Mission Directorate. Marshall also developed MAPS (Multi-spacecraft Autonomous Positioning System), the underlying networked computer navigation software. MAPS previously was tested on the International Space Station in 2018, using NASA’s Space Communications and Navigations (SCaN) Testbed.

NASA Artemis Mission Progresses with SpaceX Starship Test Flight

As part of NASA’s Artemis campaign to return humans to the Moon for the benefit of all, the agency is working with SpaceX to develop the company’s Starship human landing system (HLS), which will land astronauts near the Moon’s South Pole during the Artemis III and Artemis IV missions. On March 14, SpaceX launched the third integrated flight test of its Super Heavy booster and Starship upper stage, an important milestone toward providing NASA with a Starship HLS for its Artemis missions.

SpaceX launched the third integrated flight test of its Super Heavy booster and Starship upper stage from the company’s Starbase orbital launch pad at 8:25 a.m. CT on March 14. This flight test is an important milestone toward providing NASA with a Starship HLS for its Artemis missions.SpaceX

A complement of 33 Raptor engines, fueled by super-cooled liquid methane and liquid oxygen, powered the Super Heavy booster with Starship stacked on top, from the company’s Starbase orbital launch pad at 8:25 a.m. CDT. Starship, using six Raptor engines, separated from the Super Heavy booster employing a hot-staging technique to fire the engines before separation at approximately three minutes into the flight, in accordance with the flight plan. This was the third flight test of the integrated Super Heavy-Starship system.

“With each flight test, SpaceX attempts increasingly ambitious objectives for Starship to learn as much as possible for future mission systems development. The ability to test key systems and processes in flight scenarios like these integrated tests allows both NASA and SpaceX to gather crucial data needed for the continued development of Starship HLS,” said Lisa Watson-Morgan, HLS Program Manager at NASA’s Marshall Space Flight Center.

This test accomplished several important firsts that will contribute to the development of Starship for Artemis lunar landing missions. The spacecraft reached its expected orbit and Starship completed the full-duration ascent burn.

One objective closely tied to future Artemis operations is the transfer of thousands of pounds of cryogenic propellant between internal tanks during the spacecraft’s coast phase as part of NASA’s Space Technology Missions Directorate 2020 Tipping Point awards. The propellant transfer demonstration operations were completed, and the NASA-SpaceX team is currently reviewing the flight data that was received. This Tipping Point technology demonstration is one of more than 20 development activities NASA is undertaking to solve the challenges of using cryogenic fluids during future missions.

As a key step toward understanding how super-cooled propellant sloshes within the tanks when the engines shut down, and how that movement affects Starship’s stability while in orbit, engineers will study flight test data to assess the performance of thrusters that control Starship’s orientation in space. They are also interested to learn more about how the fluid’s movement within the tanks can be settled to maximize propellant transfer efficiency and ensure Raptor engines receive needed propellant conditions to support restart in orbit.

“Storing and transferring cryogenic propellant in orbit has never been attempted on this scale before,” said Jeremy Kenny, project manager, NASA’s Cryogenic Fluid Management Portfolio at Marshall. “But this is a game-changing technology that must be developed and matured for science and exploration missions at the Moon, Mars, and those that will venture even deeper into our solar system.”

Under NASA’s Artemis campaign, the agency will land the first woman, first person of color, and its first international partner astronaut on the lunar surface and prepare for human expeditions to Mars. Commercial human landing systems are critical to deep space exploration, along with the Space Launch System rocket, Orion spacecraft, advanced spacesuits and rovers, exploration ground systems, and the Gateway space station.

Evolved Adapter for Future NASA SLS Flights Readied for Testing

A test article of the universal stage adapter for NASA’s more powerful version of its SLS (Space Launch System) rocket arrived to Building 4619 at NASA’s Marshall Space Flight Center on Feb. 22 from Leidos in Decatur, Alabama.

The universal stage adapter will connect the rocket’s upgraded in-space propulsion stage, called the exploration upper stage, to NASA’s Orion spacecraft as part of the evolved Block 1B configuration of the SLS rocket. It will also serve as a compartment capable of accommodating large payloads, such as modules or other exploration spacecraft. The SLS Block 1B variant will debut on Artemis IV and will increase SLS’s payload capability to send more than 84,000 pounds to the Moon in a single launch.

In Building 4619’s Load Test Annex High Bay at Marshall, the development test article will first undergo modal testing that will shake the hardware to validate dynamic models. Later, during ultimate load testing, force will be applied vertically and to the sides of the hardware. Unlike the flight hardware, the development test article has flaws intentionally included in its design, which will help engineers verify that the adapter can withstand the extreme forces it will face during launch and flight.

The test article joins an already-rich history of rocket hardware that has undergone high-and-low pressure, acoustic, and extreme temperature testing in the multipurpose, high-bay test facility; it will be tested in the same location that once bent, compressed, and torqued the core stage intertank test article for SLS rocket’s Block 1 configuration. Leidos, the prime contractor for the universal stage adapter, manufactured the full-scale prototype at its Aerospace Structures Complex in Decatur.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA Study: Asteroid’s Orbit, Shape Changed After DART Impact

When NASA’s DART (Double Asteroid Redirection Test) deliberately smashed into a 560-foot-wide asteroid on Sept. 26, 2022, it made its mark in more ways than one. The demonstration showed that a kinetic impactor could deflect a hazardous asteroid should one ever be on a collision course with Earth. Now a new study published in the Planetary Science Journal shows the impact changed not only the motion of the asteroid, but also its shape.

The asteroid Dimorphos was captured by NASA’s DART mission just two seconds before the spacecraft struck its surface on Sept. 26, 2022. Observations of the asteroid before and after impact suggest it is a loosely packed “rubble pile” object.NASA/Johns Hopkins APL

DART’s target, the asteroid Dimorphos, orbits a larger near-Earth asteroid called Didymos. Before the impact, Dimorphos had a roughly symmetrical “oblate spheroid” shape – like a squashed ball that is wider than it is tall. With a well-defined, circular orbit at a distance of about 3,900 feet from Didymos, Dimorphos took 11 hours and 55 minutes to complete one loop around Didymos.

“When DART made impact, things got very interesting,” said Shantanu Naidu, a navigation engineer at NASA’s Jet Propulsion Laboratory in Southern California, who led the study. “Dimorphos’ orbit is no longer circular: Its orbital period” – the time it takes to complete a single orbit – “is now 33 minutes and 15 seconds shorter. And the entire shape of the asteroid has changed, from a relatively symmetrical object to a ‘triaxial ellipsoid’ – something more like an oblong watermelon.”

Naidu’s team used three data sources in their computer models to deduce what had happened to the asteroid after impact. The first source was aboard DART: The spacecraft captured images as it approached the asteroid and sent them back to Earth via NASA’s Deep Space Network (DSN). These images provided close-up measurements of the gap between Didymos and Dimorphos while also gauging the dimensions of both asteroids just prior to impact.

The second data source was the DSN’s Goldstone Solar System Radar, located near Barstow, California, which bounced radio waves off both asteroids to precisely measure the position and velocity of Dimorphos relative to Didymos after impact. Radar observations quickly helped NASA conclude that DART’s effect on the asteroid greatly exceeded the minimum expectations.

The third and most significant source of data: ground telescopes around the world that measured both asteroids’ “light curve,” or how the sunlight reflecting off the asteroids’ surfaces changed over time. By comparing the light curves before and after impact, the researchers could learn how DART altered Dimorphos’ motion.

As Dimorphos orbits, it periodically passes in front of and then behind Didymos. In these so-called “mutual events,” one asteroid can cast a shadow on the other, or block our view from Earth. In either case, a temporary dimming – a dip in the light curve – will be recorded by telescopes.

See the DART impact with NASA’s Eyes on the Solar System.

“We used the timing of this precise series of light-curve dips to deduce the shape of the orbit, and because our models were so sensitive, we could also figure out the shape of the asteroid,” said Steve Chesley, a senior research scientist at JPL and study co-author. The team found Dimorphos’ orbit is now slightly elongated, or eccentric. “Before impact,” Chesley continued, “the times of the events occurred regularly, showing a circular orbit. After impact, there were very slight timing differences, showing something was askew. We never expected to get this kind of accuracy.”

This illustration shows the approximate shape change that the asteroid Dimorphos experienced after DART hit it. Before impact, left, the asteroid was shaped like a squashed ball; after impact it took on a more elongated shape, like a watermelon.NASA/JPL-Caltech

The models are so precise, they even show that Dimorphos rocks back and forth as it orbits Didymos, Naidu said.

The team’s models also calculated how Dimorphos’ orbital period evolved. Immediately after impact, DART reduced the average distance between the two asteroids, shortening Dimorphos’ orbital period by 32 minutes and 42 seconds, to 11 hours, 22 minutes, and 37 seconds.

Over the following weeks, the asteroid’s orbital period continued to shorten as Dimorphos lost more rocky material to space, finally settling at 11 hours, 22 minutes, and 3 seconds per orbit – 33 minutes and 15 seconds less time than before impact. This calculation is accurate to within 1 ½ seconds, Naidu said. Dimorphos now has a mean orbital distance from Didymos of about 3,780 feet – about 120 feet closer than before impact.

“The results of this study agree with others that are being published,” said Tom Statler, lead scientist for solar system small bodies at NASA Headquarters. “Seeing separate groups analyze the data and independently come to the same conclusions is a hallmark of a solid scientific result. DART is not only showing us the pathway to an asteroid-deflection technology, it’s revealing new fundamental understanding of what asteroids are and how they behave.”

These results and observations of the debris left after impact indicate that Dimorphos is a loosely packed “rubble pile” object, similar to asteroid Bennu. ESA’s (European Space Agency) Hera mission, planned to launch in October 2024, will travel to the asteroid pair to carry out a detailed survey and confirm how DART reshaped Dimorphos.

DART was designed, built, and operated by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Planetary Defense Coordination Office, which oversees the agency’s ongoing efforts in planetary defense. The mission is a project of the agency’s Planetary Mission Program Office, which is at NASA’s Marshall Space Flight Center. DART was humanity’s first mission to intentionally move a celestial object.

Meet the Women Launching, Recovering Artemis Missions 

NASA - Breaking News - Wed, 03/20/2024 - 12:11pm
NASA/Kim Shiflett and Isaac Watson

In celebration of Women’s History Month, NASA highlights the multifaceted group of women behind the launch and recovery efforts for Artemis missions. They are a driving force in preparing and planning for crewed missions and are helping inspire the next generation of space explorers – the Artemis Generation. 

On the left is Artemis Launch Director Charlie Blackwell-Thompson and some of the women of the launch team wearing green to symbolize they are “go” for launch. As the agency prepares to return to the Moon under Artemis, the teams in the launch control center at NASA’s Kennedy Space Center in Florida are responsible for launching the SLS (Space Launch System) rocket and Orion spacecraft. The team consists of about 30% women, in contrast to when there was only one woman sitting on launch console during the Apollo 11 Moon landing mission.  

On the right is Artemis Landing and Recovery Director Lili Villarreal during Underway Recovery Test-11. This most recent recovery test marked the first time teams and the Artemis II astronauts practiced the procedures and operations they will undergo after Orion splashes down in the Pacific Ocean at the end of the Artemis II test flight.

55 Years Ago: Four Months Until the Moon Landing

NASA - Breaking News - Wed, 03/20/2024 - 11:27am

The road to the Moon landing cleared a major hurdle in March 1969 with the flight of Apollo 9 that tested all components of the spacecraft in low Earth orbit. Astronauts James A. McDivitt and Russell L. Schweickart flew the Lunar Module (LM) Spider while David R. Scott awaited their return in the Command Module (CM) Gumdrop. The success of Apollo 9 paved the way for Apollo 10, the next mission planned for May, to test the combined spacecraft in lunar orbit. Preparations for Apollo 10 continued with the rollout of the Saturn V to its launch pad. And if that dress rehearsal mission completed all its objectives, Apollo 11 could achieve the first Moon landing in July. The astronauts for that mission continued their training as engineers tested the spacecraft and assembled the rocket.

At 11 a.m. on March 3, 1969, Apollo 9 lifted off from Launch Pad 39A at NASA’s Kennedy Space Center (KSC) in Florida. For only the second time, the giant Saturn V lifted three astronauts into space. Although planned for Feb. 28, managers delayed the liftoff by three days to give the astronauts time to recover from upper respiratory infections. The incident prompted NASA to institute a preflight medical quarantine for astronauts on future missions to minimize their risk of contracting infectious diseases.

Right: In Mission Control at the Manned Spacecraft Center, now NASA’s Johnson Space Center in Houston, Apollo 9 Lead Flight Director Eugene F. Kranz, seated, monitors the flight’s progress.

Controllers in Firing Room 2 of the Launch Control Center (LCC) monitored Apollo 9’s smooth countdown. Vice President Spiro T. Agnew, who chaired the National Aeronautics and Space Council, attended the launch, escorted by NASA Acting Administrator Thomas O. Paine and KSC Director Kurt H. Debus. As soon as the Saturn V cleared the launch tower, control of the flight switched from the LCC to Mission Control at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Apollo 9 Lead Flight Director Eugene F. Kranz and his team of controllers monitored the launch. Eleven minutes after liftoff, the Saturn V’s three stages placed Apollo 9 in orbit around the Earth. During the 10-day mission, Flight Directors Gerald D. Griffin and M.P. “Pete” Frank took their turns along with Kranz leading their teams to monitor the flight.

Schweickart on Spider’s front porch during the mission’s dual spacewalk – note fellow astronaut David R. Scott reflected in Schweickart’s visor. Right: Scott in the open hatch of the Command Module Gumdrop.

Two hours and 41 minutes after launch, the Command and Service Module (CSM) separated from the S-IVB third stage and pulled a safe distance away to begin the Transposition and Docking maneuver. Scott turned Gumdrop around to face Spider, still attached to the S-IVB, and slowly closed the gap between the two spacecraft, completing the first successful docking of the Apollo program. About an hour later, springs ejected the docked spacecraft from the S-IVB. Over the next few hours, ground controllers twice restarted the S-IVB’s engine to simulate a Trans Lunar Injection, eventually sending the spent rocket stage into solar orbit. Meanwhile, the astronauts pressurized the tunnel between Gumdrop and Spider and connected umbilicals to power the LM while the two spacecraft remained docked. The astronauts next performed the first of eight planned burns of the Service Module’s (SM) Service Propulsion System (SPS) engine, a five-second maneuver that raised the spacecraft’s orbit. The burn validated that the docking mechanism between the two vehicles and that the LM itself could withstand the firing of the large SPS engine. The crew settled down for their first night’s sleep in space – for the first time in the Apollo Program, all crew members slept at the same time and not in shifts as on previous missions. The next day, the crew conducted three SPS engine burns of varying durations to demonstrate the controllability of the docked vehicles using the spacecraft’s digital autopilot.

The third day saw the initial activation of the LM Spider. Schweickart first and then McDivitt floated through the tunnel from Gumdrop. They closed the hatch, brought the LM’s systems to life, and extended the vehicle’s four landing legs. McDivitt informed Mission Control that Schweickart had experienced symptoms of space motion sickness, including vomiting twice, but that he now felt better.  Mission Control, in consultation with flight surgeons and the crew, agreed that the mission could continue as planned, but out of an abundance of caution they curtailed the spacewalk scheduled for the next day. Instead of translating to Gumdrop and back as originally planned, Schweickart would remain on Spider’s front porch to evaluate the spacesuit and the Portable Life Support System (PLSS) backpack. Schweickart and McDivitt then began the first TV transmission of the mission, a seven-minute broadcast showing the duo in the confined space of the LM.

McDivitt and Schweickart moved on to perform the first test of the Descent Propulsion System (DPS) engine, the rocket used to land the LM on the Moon. Although successfully tested during the uncrewed Apollo 5 mission in January 1968, this test included a CSM docked to the LM. The burn evaluated if the LM’s engine could serve as a backup in case of a problem with the SPS – in retrospect a very useful test given Apollo 13 relied on the method just over a year later. After the 372-second burn, capsule communicator (capcom) Stuart A. Roosa called up to the crew, “Spider, that was a beautiful burn, man, you were right down the tube,” generating this response from McDivitt, “Looked pretty neat from here, too.” McDivitt and Schweickart deactivated Spider for the night and transferred back to Gumdrop. The crew conducted the 43-second fifth burn of the SPS to circularize the spacecraft’s orbit.

The Apollo 9 astronauts began their fourth day in space by donning their spacesuits and Schweicakrt and McDivitt once again transferred to Spider. In the LM, Schweickart, fully recovered from his earlier illness, donned the PLSS that provided him with oxygen during his spacewalk. Scott received his life support via umbilicals connected to the CM and McDivitt similarly used the LM’s life support system.  McDivitt depressurized Spider, and minutes later Scott did the same with Gumdrop. Schweickart floated out through the LM’s side hatch onto the front porch, exclaiming “Hey, this is like spectacular.” He placed his feet into specialized gold-painted foot restraints dubbed the “golden slippers.” Scott then opened the CM side hatch and floated partway out of the spacecraft. Mission Control now communicated with three different parties, with Schweickart picking up the callsign Red Rover, a nod to his red hair. Scott retrieved thermal samples from the outside of Gumdrop. Schweickart did the same from the outside of Spider and tested out the handrails near the hatch and found them to be easy for maneuvering. Scott and Schweickart reentered their respective vehicles, having each spent about 37 minutes outside. Mission Control considered this first, and the only one before the Moon landing, test of the spacesuits and PLSS a complete success. After a 15-minute TV broadcast, McDivitt and Schweickart returned to Gumdrop to rejoin Scott for the night.

Middle: McDivitt and Schweickart aboard Spider’s ascent stage have returned to Gumdrop. Right: View of Gumdrop from Spider.

For their fifth day in space, the Apollo 9 crew had a full plate – undocking of Spider from Gumdrop, testing the LM’s Descent and Ascent Stage engines by conducting separation maneuvers followed by a rendezvous and docking with the CM. This marked the first time astronauts flew in a spacecraft not designed to reenter the Earth’s atmosphere, making redocking with Gumdrop essential. Spider backed away from Gumdrop to about 50 feet and began a slow turn so Scott in the CM could inspect it. He commented about Spider, “That’s a nice looking machine.” A small 10-second burn by the SM’s Reaction Control System (RCS) thrusters increased the separation distance to about three miles. About 45 minutes after undocking, McDivitt fired Spider’s DPS engine for 19 seconds, first at 10% thrust then throttling it up to 40% thrust, to begin the separation maneuver that placed it about 50 miles from Gumdrop before orbital mechanics brought the two spacecraft closer again. The next maneuver in the separation sequence, a 22-second DPS burn, opened the distance to about 100 miles. 

To begin the rendezvous back to Gumdrop, McDivitt first fired Spider’s Ascent Stage RCS thrusters for 32 seconds, at the same time jettisoning the Descent Stage. It remained in orbit until March 22, burning up on reentry over the Indian Ocean. The next rendezvous maneuver, lasting three seconds, tested the Ascent Propulsion System (APS) engine for the first time, followed by a second APS burn lasting 38 seconds, putting Spider on an intercept course with Gumdrop. Two small course corrections refined the trajectory and Spider stopped about 100 feet from Gumdrop to begin a pitchover maneuver, allowing Scott to inspect the ascent stage including its engine, commenting, “You’re the biggest, friendliest, funniest looking Spider I’ve ever seen.” The two craft docked, having flown separately for six hours 23 minutes. Two hours after docking, McDivitt and Schweickart rejoined Scott in Gumdrop, and then they jettisoned Spider. Mission Control commanded Spider’s APS to fire for six minutes, placing it into a highly elliptical Earth orbit from which it did not decay until Oct. 23, 1981. The Apollo 9 astronauts had met their mission’s primary objectives, and they still had five more days in space.

The first major task of flight day six involved the sixth SPS engine. This brief one and a half second burn lowered the low point of Gumdrop’s orbit, to enhance a backup capability to use the RCS thrusters for the deorbit burn at the end of the mission, should a problem arise with the SPS. Shortly after this burn, the crew set up the one formal scientific investigation of their mission – Experiment S065 Multispectral Terrain Photography, a cluster of four Hasselblad 70 mm cameras mounted in Gumdrop’s round hatch window. The experiment provided photographs taken simultaneously in four specific portions of the visible and near infrared spectrum. The experiment served as a precursor for the Earth Resources Technology Satellite (ERTS), later renamed Landsat, and for multispectral photography conducted aboard the Skylab space station in the early 1970s. Over the next four days, the astronauts continued observations with the S065 camera system, exposing 127 complete four-frame sets.

On flight day eight, the crew completed the seventh SPS burn, a 25-second firing to establish the proper trajectory for the deorbit burn. On Mar. 13, 1969, after 151 revolutions around the Earth and while passing over Hawaii, the crew fired the SPS engine for the eighth and final time. Lasting just under 12 seconds, the burn brought Apollo 9 out of orbit. Gumdrop separated from its SM and pointed its heat shield in the direction of flight. During reentry, a sheath of ionized gas formed around the capsule by the rapid deceleration led to a 4-minute radio blackout, after which the drogue parachutes deployed. The three main parachutes opened at 10,000 feet altitude, slowing the spacecraft to about 22 miles per hour at splashdown.

The splashdown occurred in the Atlantic Ocean about 670 miles south-southwest of Bermuda, and about 3 miles from the prime recovery ship the U.S.S. Guadalcanal (LPH-7). McDivitt, Scott, and Schweickart had spent 241 hours and 54 seconds in space. Forty-nine minutes after splashdown, recovery teams had the crew aboard the recovery ship. The next day, a helicopter flew them to Eleuthera in the Bahamas, where they boarded a plane to KSC for a brief ceremony, and then back to Houston for a large welcome home reception and a reunion with their families at Ellington Air Force Base. The successful Apollo 9 mission, the most complex crewed space mission flown to that time, brought the Moon landing one step closer.

Workers offloaded Gumdrop from the Guadalcanal in Norfolk, Virginia, for transport aboard a U.S. Air Force cargo jet to Long Beach, California, from where they trucked it to the North American Rockwell plant in Downey for postflight inspection. NASA transferred Gumdrop to the Smithsonian Institution in 1973. In 1977, it went on display at the Michigan Space and Science Center in Jackson, Michigan, McDivitt’s hometown. When that facility closed in 2004, Gumdrop transferred to the San Diego Air & Space Museum, where visitors can view it today.

On March 11, as the Apollo 9 astronauts neared the end of their mission, workers at KSC rolled the Apollo 10 Saturn V vehicle from the Vehicle Assembly Building (VAB) to its launch pad. Apollo 10’s assembly marked the first use of the VAB’s High Bay 2, requiring the stack to exit the VAB’s rear and make a sweeping loop around the building to reach the crawlerway to the launch pads. Apollo 10 also marked the first use of Pad 39B. On March 17, NASA managers formally set Apollo 10’s launch date as May 18. Apollo 10 astronauts Thomas P. Stafford, John W. Young, and Eugene A. Cernan and their backups L. Gordon Cooper, Donn F. Eisele, and Edgar D. Mitchell continued training in spacecraft simulators and testing their spacesuits in vacuum chambers. On March 27, the prime crew conducted a walk-through of Pad 39B and trained on emergency escape procedures. The next day, the backup crew practiced water egress training in the Water Immersion Facility in MSC’s Building 260, and repeated the training in the Gulf of Mexico the following week.

Workers in the VAB’s High Bay 3 stacked the Apollo 11 Saturn V’s S-IC first stage on Feb. 21. They added the S-II second stage and S-IVB third stage on March 4 and 5, respectively. The spacecraft for Apollo 11 continued testing in KSC’s Manned Spacecraft Operations Building (MSOB). With their historic mission only five months away, the Apollo 11 prime crew of Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin and their backups James A. Lovell, William A. Anders, and Fred W. Haise busied themselves training for the Moon landing, spending time in spacecraft simulators. The prime and backup crews participated in altitude chamber tests of both their CM and LM.

Mobile Quarantine Facility, Lunar Receiving Laboratory, and Lunar Module Drop Tests

Right: Workers at Norfolk Naval Air Station in Virginia lift the MQF off the Guadalcanal onto a truck for its return to Houston.

Preparations for ground support facilities for the first lunar landing mission continued. In conjunction with the Apollo 9 splashdown and recovery operations aboard the Guadalcanal, NASA conducted a simulation of recovery operations of astronauts returning from a lunar mission. NASA Flight Surgeon Dr. William R. Carpentier, project engineer John K. Hirasaki, and three astronaut stand-ins, Paul H. Kruppenbacher, Michael T. “Tex” Ward, and Arthur E. Lizza, spent 10 days inside a Mobile Quarantine Facility (MQF), a modified Airstream trailer designed to temporarily house astronauts returning from the Moon. The three astronaut surrogates began the simulation by entering a mockup CM that sailors placed in the ocean and recovered as if returning from a space mission. The trio donned Biological Isolation Garments (BIG), meant to prevent contamination of Earth by any possible lunar organisms. Once on board the Guadalcanal, the three accompanied by Carpentier and Hirasaki entered the MQF for four days, where the just-recovered Apollo 9 crew visited them through the window of the trailer. The five stayed inside the MQF except for the short time it was transferred from the Guadalcanal to a waiting transport aircraft at Norfolk Naval Air Station and flown back to Houston. After offloading, the MQF and its five inhabitants transferred to the Lunar Receiving Laboratory (LRL) in MSC’s Building 37 to begin a simulated quarantine. Overall, the exercise tested the procedures for the activities after the first lunar landing mission, with many lessons learned.

Middle: The Vibration and Acoustics Test Facility (VATF) at MSC. Right: The Lunar Module during drop testing in the VATF.

Managers, scientists, technicians, and engineers conducted a 30-day simulation in the LRL, the most complex test of the facility to verify that all its components would be ready to support crewmembers and their samples returning from the Moon, possibly by July 1969. A separate seven-day simulation of the astronaut quarantine capabilities in the LRL’s Crew Reception Area began on March 25. Fifteen NASA and contractor employees, most of whom would participate in the activities following the actual lunar landing mission, demonstrated the logistics of maintaining astronauts and support staff in isolation. All biological barriers operated during the simulation, and the only contact test personnel had with the outside world was via telephone or through glass walls.  The first part of the test included the simulated arrival of lunar materials and film, followed the next day by the arrival of the stand-in crew. The last part of the test included the process for releasing the crew and personnel from quarantine.

The Structures and Mechanics Division at MSC conducted a series of drop tests in the Vibration and Acoustic Test Facility (VATF) to verify that the LM’s systems would operate following a lunar landing. The LM’s manufacturer, the Grumman Aircraft Engineering Corporation, located in Bethpage, New York, provided technical support for the tests using LM-2, a flight qualified  vehicle with all subsystems installed. To simulate the LM’s configuration at landing, workers filled the tanks in the ascent stage with inert fluid to mimic a full load of fuel, while keeping the descent stage tanks mostly empty as they would be following the powered descent from orbit. The series of five tests began on March 21, 1969, and finished on May 7. Engineers dropped LM-2 from heights ranging from eight to 24 inches onto artificial slopes and obstructions to simulate landings on rough lunar terrain. Successful completion of the drop tests removed a constraint from carrying out the first lunar landing. Visitors can view LM-2 on display at the Smithsonian Institution’s National Air and Space Museum in Washington, D.C.

In case Apollo 11 could not achieve the Moon landing in July, NASA planned to try again with Apollo 12 in September. To protect for that launch date, components of the rocket and spacecraft began arriving at KSC. The Saturn V’s S-IVB third stage arrived on March 10 and workers placed it in storage in the VAB until the other two stages arrived in April and May. The Apollo 12 LM’s two stages arrived on March 24, and workers transported them to the MSOB. The CM and SM arrived four days later, and they shared space in the MSOB with the Apollo 11 spacecraft undergoing testing.

Key Test Drive of Orion on NASA’s Artemis II to Aid Future Missions

NASA - Breaking News - Wed, 03/20/2024 - 10:58am

Astronauts will test drive NASA’s Orion spacecraft for the first time during the agency’s Artemis II test flight next year. While many of the spacecraft’s maneuvers like big propulsive burns are automated, a key test called the proximity operations demonstration will evaluate the manual handling qualities of Orion.

During the approximately 70-minute demonstration set to begin about three hours into the mission, the crew will command Orion through a series of moves using the detached upper stage of the SLS (Space Launch System) rocket as a mark. The in-space propulsion stage, called the ICPS (interim cryogenic propulsion stage), includes an approximately two-foot target that will be used to evaluate how Orion flies with astronauts at the controls.

“There are always differences between a ground simulation and what an actual spacecraft will fly like in space,” said Brian Anderson, Orion rendezvous, proximity operations, and docking manager within the Orion Program at NASA’s Johnson Space Center in Houston. “The demonstration is a flight test objective that helps us reduce risk for future missions that involve rendezvous and docking with other spacecraft.”

After NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen are safely in space, the Moon rocket’s upper stage will fire twice to put Orion on a high Earth orbit trajectory. Then, the spacecraft will automatically separate from the rocket stage, firing several separation bolts before springs push Orion a safe distance away.

As the spacecraft and its crew move away, Orion will perform an automated backflip to turn around and face the stage. At approximately 300 feet away, Orion will stop its relative motion. The crew will take control and use the translational and rotational hand controllers and display system to make very small movements to ensure Orion is responding as expected.

Next, the crew will very slowly pilot Orion to within approximately 30 feet of the stage. A two-foot auxiliary target mounted inside the top of the stage, similar to the docking target used by spacecraft visiting the International Space Station, will guide their aim.

“The crew will view the target by using a docking camera mounted inside the docking hatch window on the top of the crew module to see how well aligned they are with the docking target mounted to the ICPS,” Anderson said.

“It’s a good stand in for what crews will see when they dock with Starship on Artemis III and to the Gateway on future missions.”

About 30 feet from the stage, Orion will stop and the crew will checkout the spacecraft’s fine handling qualities to evaluate how it performs in close proximity to another spacecraft. Small maneuvers performed very close to the ICPS will be done using the reaction control system thrusters on Orion’s European Service Module.

Orion will then back away and allow the stage to turn to protect its thermal properties. The crew will follow the stage, initiate a second round of manual maneuvers using another target mounted on the side of the stage, approach within approximately 30 feet, perform another fine handling quality check out, then back away.

At the end of the demonstration, Orion will perform an automated departure burn to move away from the ICPS before the stage then fires to re-enter Earth’s atmosphere over a remote location in the Pacific Ocean. During Orion’s departure burn, engineers will use the spacecraft’s docking camera to gather precise positioning measurements, which will help inform navigation during rendezvous activities on future missions in the lunar environment, where there is no GPS system. 

Because the Artemis II Orion is not docking with another spacecraft, it is not equipped with a docking module containing lights and therefore is reliant on the ICPS to be lit enough by the Sun to allow the crew to see the targets.

“As with many of our tests, it’s possible the proximity operations demonstration won’t go exactly as expected,” said Anderson. “Even if we don’t accomplish every part of the demonstration, we’ll continue on with the test flight as planned to accomplish our primary objectives, including evaluating Orion’s systems with crew aboard in the deep space environment and keeping the crew safe during the mission.”

The approximately 10-day Artemis II flight will test NASA’s foundational human deep space exploration capabilities, the SLS rocket and Orion spacecraft, for the first time with astronauts and will pave the way for lunar surface missions, including landing the first woman, first person of color, and first international partner astronaut on the Moon.

NASA Sees Progress on Blue Origin’s Orbital Reef Life Support System

NASA - Breaking News - Wed, 03/20/2024 - 9:00am

A NASA-funded commercial space station, Blue Origin’s Orbital Reef, recently completed testing milestones for its critical life support system as part of the agency’s efforts for new destinations in low Earth orbit.

The four milestones are part of a NASA Space Act Agreement originally awarded to Blue Origin in 2021 and focused on the materials and designs for systems to clean, reclaim, and store the air and water critical for human spaceflight.

NASA is working closely with commercial companies to develop new space stations capable of providing services to NASA and others, which will ensure that the U.S. maintains a continuous human presence in low Earth orbit and provides direct benefits for people on Earth.

“These milestones are critical to ensuring that a commercial destination can support human life so NASA astronauts can continue to have access to low Earth orbit to conduct important scientific research in the unique microgravity environment,” said Angela Hart, manager of NASA’s Commercial Low Earth Orbit Development Program. “Additionally, each milestone that is completed allows NASA to gain insight into our partner’s progress on station design and development.”

Humans living and working in space do so in a closed environment that must be monitored and controlled. On the International Space Station, components for the environmental control and life support system maintain clean air and water for astronauts. The regenerative system recycles and reclaims most of the water and oxygen produced by normal human activities. This significantly reduces the amount of mass that would have to be launched to the orbiting laboratory for these functions.

Orbital Reef will have a similar system in place. All four milestones tested different parts of the system, including a trace contaminant control test, water contaminant oxidation test, urine water recovery test, and water tank test.

The trace contaminant control test screened materials to remove harmful impurities from the air. The water containment oxidation test, urine water recovery test, and water tank test all focused on potential cleaning, reclaiming, and storing technologies.

NASA is supporting the design and development of multiple commercial space stations, including Blue Origin’s Orbital Reef, through funded and unfunded agreements. The current design and development phase will be followed by the procurement of services from one or more companies, where NASA aims to be one of many customers for low Earth orbit destinations.

NASA’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost and enable the agency to focus on Artemis missions to the Moon in preparation for Mars, while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

NASA, Industry Improve Lidars for Exploration, Science

NASA - Breaking News - Tue, 03/19/2024 - 2:07pm

5 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA engineers will test a suite of new laser technologies from an aircraft this summer for Earth science remote sensing. Called lidar, the instruments could also be used to improve models of the Moon’s shape and aid the search for Artemis landing sites.

Similar to sonar, but using light instead of sound, lidars calculate distances by timing how long a laser beam takes to reflect off a surface and return to an instrument. Multiple pings from the laser can provide the relative speed and even 3D image of a target. They increasingly help NASA scientists and explorers navigate, map, and collect scientific data.

Engineers and scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, continue to refine lidars into smaller, lighter, more versatile tools for science and exploration, with help from hardware provided by small business and academic partners.

“Existing 3D-imaging lidars struggle to provide the 2-inch resolution needed by guidance, navigation and control technologies to ensure precise and safe landings essential for future robotic and human exploration missions,” team engineer Jeffrey Chen said. “Such a system requires 3D hazard-detection lidar and a navigation doppler lidar, and no existing system can perform both functions.”

Engineer Jeffrey Chen tests a CASALS lidar prototype on the roof of Goddard’s Building 33.NASA

Enter CASALS, the Concurrent Artificially intelligent Spectrometry and Adaptive Lidar System. Developed through Goddard’s IRAD, Internal Research and Development program, CASALS shines a tunable laser through a prism-like grating to spread the beam based on its changing wavelengths. Traditional lidars pulse a fixed-wavelength laser which is split into multiple beams by bulky mirrors and lenses to split it into multiple beams. One CASALS instrument could cover more of a planet’s surface in each pass than lidars used for decades to measure Earth, the Moon, and Mars.

CASALS’s smaller size, weight, and lower power requirements enable small satellite applications as well as handheld or portable lidars for use on the Moon’s surface, Goddard engineer and CASALS development lead Guangning Yang said.

The CASALS team received funding from NASA’s Earth Science Technology Office to test their improvements by airplane in 2024, bringing their system closer to spaceflight readiness.

What Color is Your Lidar?

As lidars become more specialized, CASALS can incorporate different wavelengths, or colors of laser light for applications like Earth science, exploring other planets and objects in space, and navigation and rendezvous operations.

The CASALS Team used Goddard IRAD and NASA SBIR (Small Business Innovation Research Program) funding along with commercial partners Axsun Technologies and Freedom Photonics to develop new fast-tuning lasers in the 1-micron portion of the infrared spectrum for Earth science and planetary exploration. By comparison, commonly available lidars used for self-driving vehicle development typically use 1.5-micron lasers for range and speed calculations.

On Earth, wavelengths near 1 micron pass readily through the atmosphere and are good at differentiating vegetation from bare ground, said Ian Adams, Goddard’s chief technologist for Earth sciences. Wavelengths near 0.97 and 1.45 microns offer valuable information about water vapor in Earth’s atmosphere but do not travel as efficiently to the surface.

In a related project, the team partnered with Left Hand Design Corporation to develop a steering mirror to extend CASALS’s 3D-imaging coverage and improve resolution. He said the lidar’s higher pulse rate can build up signal sensitivity to provide range and velocity measurements at up to 60 miles.

Artemis-related missions seeking to land near the Moon’s South Pole could also use CASALS’s sharper imaging to help assess the safety of potential landing sites.

Bringing the Moon into Focus

More detailed 3D models of the Moon drove Goddard planetary scientist Erwan Mazarico’s IRAD effort to refine CASALS’s ability to measure surface details smaller than 3 feet. He said this will help understand the Moon’s sub-surface structures and changes over time.

Every month, Earth’s path across the lunar sky moves within 10 or 20 degrees of the center of the side facing Earth.

“We’ve predicted based on our understanding of its inner structure that Earth’s shifting pull could change the tidal bulge or shape of the Moon,” Mazarico said. “High-resolution measurements of that deformation could tell us more about potential variations within the Moon. Is it responding like a fully uniform body in the interior?”

Lunar Reconnaissance Orbiter’s Lunar Orbiting Laser Altimeter has produced detailed maps of the Lunar South Pole, including where water ice appears to fill the bottoms of permanently shadowed craters.NASA / LRO

NASA’s Lunar Reconnaissance Orbiter (LRO) has measured Earth’s natural satellite since 2009, modeling the Moon’s terrain and providing a wealth of discoveries with the help of LOLA, its Lunar Orbiting Lidar Altimeter. LOLA fires 28 laser pulses per second, split into five beams touching the surface 65 feet to 100 feet apart. Scientists use LRO images to estimate smaller surface features between laser measurements.

CASALS’s laser, however, allows the equivalent of several hundred thousand pulses per second, reducing the distance between surface measurements.

“A denser and more accurate data set would allow us to study much smaller features,” Mazarico said, including those from impacts, volcanic activity, and tectonics. “We’re talking orders of magnitude more measurements. That could be quite a big game changer in terms of the type of data we get from lidar.”

Sketch the Shape of the Sun for Science During the Solar Eclipse

Calling all eclipse admirers!

The SunSketcher team is looking for one million volunteers to capture photos on their cell phones during the April 8 total solar eclipse. These images will help scientists learn about the size, shape, and inner structure of the Sun.

This NASA-funded citizen science project invites anyone who will be within the path of totality in the U.S. to take photos of the Baily’s Beads effect, which occurs when little points of sunlight pass through the valleys in between the mountains on the edge of the Moon. It’s the last piece of the Sun seen before totality and the first to appear after totality. For a few seconds, these glimmers of light look like beads along the Moon’s edge.

The Baily’s Beads effect is seen as the Moon makes its final move over the Sun during the total solar eclipse on Aug. 21, 2017, above Madras, Oregon. This effect occurs when gaps in the Moon’s rugged terrain allow sunlight to pass through in some places just before the total phase of the eclipse. NASA/Aubrey Gemignani

The SunSketcher app will use smartphones to automatically take a sequence of images as Baily’s Beads appear. Volunteers will simply download a free app, activate it just before totality, set the phone down with the rear camera pointed at the Sun, and leave it alone. The app will use the phone’s GPS location to calculate when Baily’s Beads will be visible.

“All you need is a cell phone,” says Gordon Emslie, SunSketcher’s project lead and professor of physics and astronomy at Western Kentucky University. “How many science projects can you do with the equipment you already have in your pocket?”

Emslie says the cell phone images of Baily’s Beads will look fairly simple, but the tiny dots of light will provide crucial data about our star.

“It’s the precise timing of when these flashes appear and disappear that can tell you how big the Sun is and what shape it is,” Emslie says.

Citizen scientists will activate the Sunsketcher app before the eclipse and then prop their phone against a steady surface with the rear (back-facing) camera pointed at the Sun. The app will automatically take images of Baily’s Beads at the correct times. SunSketcher/Tabby Cline

The SunSketcher team will merge the images collected from various viewpoints on the eclipse path to create an evolving pattern of beads. This pattern will be compared with 3D maps that show the exact locations and distances between lunar craters, mountains, and valleys on the surface of the Moon from NASA’s Lunar Reconnaissance Orbiter. The combined measurements will allow researchers to calculate the precise size and shape of the Sun based on the timing of the images captured over 90 minutes of eclipse observations.

“The fascinating thing about this is you can really only do this by having observers stretched over the whole eclipse path,” Emslie explains. “No one observer can monitor an eclipse for more than about four or five minutes.”

The Sun is round but not a perfect sphere. It bulges out slightly along the equator with a diameter of about 865,000 miles. Scientists suspect the shape of the Sun changes slightly as it goes through 11-year cycles of fluctuating solar activity. The Sun is a rotating ball of gas and plasma with complicated internal flows of material, energy, and magnetic fields beneath the surface that vary over that cycle and impact its overall shape.

“All of these flows connect to the surface somehow, and so the shape of the surface is determined by the details of the flows,” Emslie says. “If we can understand the subsurface flows, we can better understand the Sun’s internal structure.”

The Sun’s shape also determines its gravitational field, which affects the motions of the planets, so measuring the Sun’s precise shape will help scientists test theories of gravity.

Participants in the SunSketcher project can be located anywhere in the eclipse’s path of totality in the U.S., which stretches from Texas to Maine, on April 8. Emslie says the more people involved, the more worthwhile the project will be. “Literally, we’re looking for a million people to play.”

  • Download the free app from your phone’s app store (available now on iOS and coming soon on Android).
  • Initiate the app around five minutes before totality. No internet connection is required.
  • If possible, turn on “Do Not Disturb” in your phone’s settings to prevent vibrations that could disturb the image sequence.
  • Prop the phone against a steady surface (such as a rock, book, phone stand, or tripod) with the rear (back-facing) camera pointed at the Sun.
  • Let it be! The app will automatically take images of Baily’s Beads at the correct times.
  • Enjoy the eclipse! Remember to use specialized eye protection for solar viewing except during the brief total phase of a total solar eclipse, when the Moon completely blocks the Sun.
After the Eclipse
  • The app will show a directory of images taken and will request user permission to share them. Only time and location data will be recorded with the images. No personally identifiable or private information will be collected.
  • Once an internet connection is established, the images will be automatically uploaded to a central server and a screen will appear with a thank-you message.

Casey Honniball: Finding Her Space in Lunar Science

NASA - Breaking News - Tue, 03/19/2024 - 1:16pm

Lunar scientist Casey Honniball conducts lunar observations and field work near volcanoes to investigate how astronauts could use instruments during moonwalks.

Name: Casey Honniball
Title: Lunar scientist
Organization: Planetary Geology, Geophysics, and Geochemistry Laboratory, Science Directorate (Code 698)

Casey Honniball is a lunar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Courtesy of Casey Honniball

What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?

I study the Moon using Earth-based telescopes to understand the lunar volatile cycle. I also conduct field work at volcanic sites to investigate how astronauts can utilize instruments during moonwalks.

Why did you want to be a lunar scientist?

When I was 6 years old and in first grade, I was diagnosed with dyslexia. I was tutored and had help with homework and tests, which continued until I was a junior in high school. At that point, I learned to manage my dyslexia.

Because I was not good at reading and writing, I turned to more physical things such as things I could touch and build. I discovered physics in high school, which turned me on to other sciences.

I went to college for physics, but learned that I preferred astronomy. In graduate school I realized I wanted to be a lunar scientist.

I have a B.S. in astronomy from the University of Arizona, a master’s in geology and geophysics from the University of Hawaiʻi at Manoa, and a Ph.D. in Earth and planetary science also from the University of Hawaiʻi at Manoa.

While doing my master’s, one of my advisers introduced me to Earth-based lunar observation to look at hydration on the surface of the Moon. I found that I really liked the Moon and found my place in science.

What brought you to Goddard?

During graduate school, I worked with Goddard’s Dr. Kelsey Young on a field deployment testing instruments for astronauts. In 2020, I became a post-doctoral fellow for her at Goddard.

In January 2023, I became a visiting assistant research scientist in the Planetary Geology, Geophysics, and Geochemistry Laboratory through CRESSTII, and Kelsey is still my mentor.

As your mentor, what is the most important advice Kelsey Young has given you?

Kelsey helps me stay passionate about the work I am doing. She does this by providing new and exciting opportunities and being supportive about work-life balance.

I admire Kelsey’s spirit of adventure and her passion for field work. I appreciate all she has done for me and am grateful for the opportunities she and our lab have provided.

What sorts of instruments do you test for use on the Moon?

I test the use of mid- to long-wave infrared instruments for reconnaissance of a location prior to astronauts setting foot outside a vehicle. For example, an instrument on a rover can scan the area to characterize the minerology and volatiles including water, carbon dioxide, sulfur, methane, and similar chemicals. This then allows astronauts and scientists to select locations to collect samples.

I test this procedure on Earth by doing field work.

What is the most exciting field work you have done to test those instruments?

In 2015, I went to the Atacama Desert in Chile to install a radio camera on an existing telescope. I spent about a month installing the camera and observing on the telescope. There were only about 15 people I interacted with during that time. The area is very Martian-like; it is very red, dry, and barren, although we saw wild donkeys.

During Christmas of 2015 and again in 2016, one month each time, I went to Antarctica to launch a high-altitude balloon radio telescope. I lived at McMurdo Station and worked at their balloon facility near the airstrip. Antarctica is a completely different experience than you could imagine. You are so cut off from civilization. You have only the people who are there, although, I was there during Antarctica’s summer when McMurdo had many people. You are in a completely barren landscape that is so magnificently beautiful.

In 2018, I deployed an instrument I built to the Kīlauea Lava Lake on the Big Island of Hawaii. This is a National Park with thousands of visitors yearly. The lava lake was active at the time. We could see lava spewing out at different vent locations in the lake. It was very exciting and kind of scary. We had special permits allowing us into restricted areas closer to the lake. We were told not to get any closer to the cliff edge of the lake than our height so that if we tripped, we would not fall into the active lava.

I’d love to do field work in Iceland. Iceland is a great location for planetary field analog research as it has a similar landscape and geologic context to the Moon and Mars.

What outreach do you do that inspires others with dyslexia?

I like to talk to elementary through high school students about life as a scientist and how I got to where I am. I like to tell my story about learning to manage dyslexia to hopefully inspire others.

What do you do for fun?

I am a deep-sea scuba certified diver. I mainly dove in Hawaii because I was living there. I also enjoy working out, hiking, baking sourdough bread, and being with my family.

Where do you see yourself in five years?

I hope to be supporting Artemis science operations on the surface of Moon and continuing to studying the Moon’s surface remotely and conducting research through field deployments.

What is your “six-word memoir”? A six-word memoir describes something in just six words.

Fear is a state of mind.

Tech Today: NASA Helps Find Where the Wildfires Are

NASA - Breaking News - Tue, 03/19/2024 - 11:20am

2 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) In 2022, nearly 100 large wildland fires burned in the U.S. West. Almost two dozen of those burned Washington and Oregon alone, filling the air with smoke. Plumes from the fires often could easily be seen from space.Credit: NASA

Globally, nearly all wildfires start with a human ignition source – not lightning strikes or wildlife encountering power equipment. Knowing humans can be a primary cause is an example of the sort of knowledge that helps predict and prevent wildfires, a challenge that NASA and the firefighting industry are undertaking together. 

As wildfires become more common in rarely experienced countries like Ireland and are more intense in other areas impacted by climate change, governments and businesses are turning to space for help.

Landsat satellite Earth-observation data, artificial intelligence, and machine learning now predict and monitor fires and support post-fire recovery. San Diego-based Technosylva Inc. provides firefighters with a wildfire monitoring service that combines all these technologies. The company also uses other NASA fire data resources compiled by the agency’s Ames Research Center in Silicon Valley to assist during the fire season and beyond.

Satellite imagery helps Technosylva’s Wildfire Analyst identify areas previously burned by wildfire to eliminate those areas without fuel like leaves or grasses (black circles) and pinpoint areas different types of available fuel (colored circles).Credit: Technosylva Inc.

Technosylva uses data fusion, which integrates multiple data sources from climate, weather, landscapes, and human infrastructure, to develop a complete picture of current fire risks. Before fire season begins, these efforts help develop more resilient landscapes to make communities safer. During the fire season, models predict how fires will spread, and provide real-time equipment and personnel tracking across vast tracts of land.

During the 2017 Las Máquinas wildfire in Chile – a fire so large the only way to view the perimeter was from space – Technosylva assisted in firefighting efforts by providing satellite data to help identify new hot spots and guided containment efforts.

Expedition 69 Astronauts Tour NASA Goddard, Speak With Employees

NASA - Breaking News - Tue, 03/19/2024 - 11:17am

A trio of astronauts visited with employees at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, on March 18, 2024, to share their spaceflight experiences aboard the International Space Station.

NASA astronauts Stephen Bowen and Warren “Woody” Hoburg, and United Arab Emirates astronaut Sultan Alneyadi all served as flight engineers on the Expedition 69 crew aboard the International Space Station last year.

Over 40 employees at NASA’s Goddard Space Flight Center in Greenbelt, Md., participated in a meet and greet with visiting astronauts on March 18, 2024.

The astronauts engaged with over 40 center employees during a meet and greet at the beginning of their visit. Employees viewed a 20-minute video that highlighted the astronauts’ preparation for the mission and their time in space. Afterward, they answered questions about daily life aboard the International Space Station.

“These are people that you see growing up, and you hear about them, but to actually be in person with them is beyond words,” said Emily Wilson, an intern at Goddard. “It’s really awesome to hear their stories.”

During their time in space, the Expedition 69 crew studied how materials burn in microgravity to understand spacecraft fire hazards, and they worked with technology to monitor how spaceflight stressors like microgravity and radiation impact the immune system. Bowen, Hoburg, and Alneyadi also completed spacewalks during the mission.

After their presentation to employees, the astronauts toured Goddard and heard from researchers about the exciting science and missions in work at the center. They listened to a presentation from Dr. Antti Pulkkinen, director of Goddard’s Heliophysics Science Division, and they visited the clean room where engineers are building the Nancy Grace Roman Space Telescope. Their time at Goddard concluded at the Hubble Space Telescope Operations Control Center.

“The long history is really amazing, of all the contributions Goddard has made,” Hoburg said. “We’re truly going after those big fundamental questions about the origins of the universe, and all the kind of inspiring big scientific questions that drive us as humans, and it’s cool to see the contribution Goddard makes to all those big questions.”
