These earthly godfathers of Heaven's lights, that give a name to every fixed star, have no more profit of their shining nights than those that walk and know not what they are.

I Am Artemis: Mat Bevill

Significant events in history keep finding Mat Bevill. As the associate chief engineer for NASA’s SLS (Space Launch System) Program, Bevill assists the program chief engineer by interfacing with each of the element chief engineers and helping make critical decisions for the development and flight of the SLS mega rocket that will power NASA’s Artemis campaign. With the launch of Artemis II, the first crewed test flight of SLS and the Orion spacecraft, Bevill’s technical leadership and support for the SLS Chief Engineer’s Office will place him, once again, at a notable moment in time.

“Think of me as the assistant coach. While the head coach is on the front line leading the team, I’m on the sidelines providing feedback and advising those efforts,” said Bevill. As a jack-of-all-trades, he enables progress in any way that he can, something he’s familiar with after 37 years with NASA. And, on Nov. 16, 2022, as the SLS rocket roared to life for the first time with the Artemis I test flight, Bevill couldn’t help but reflect on a lifetime of experiences and lessons that led to that moment.

Bevill began his NASA career while he was still attending the University of Tennessee at Chattanooga. During his sophomore year as a mechanical engineer student, he applied for the agency’s internship program at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Just a few months before Bevill began his journey with NASA, the Challenger accident occurred, taking the lives of all seven crewmembers in January 1986. Bevill joined the Solid Motor Branch at Marshall as teams across the agency worked to understand the cause of the accident. It was a fast-paced environment, and Bevill had to learn quickly about the solid rocket boosters.

“It was a surreal experience, but I was privileged to work with those people. We were figuring out tough lessons together and working toward a common goal,” Bevill recalls.

Those tough lessons provided Bevill with tremendous hands-on experience related to the solid rocket booster hardware that would not only shape his career, but, later, the SLS rocket. The five-segment solid rocket boosters that provide more than 75% of thrust for SLS to go to the Moon are based on the same four-segment design that powered 135 shuttle missions to low Earth orbit. His experience from his time with the shuttle led him to deputy chief engineer for the SLS Boosters Office.

Just as for Artemis I, Bevill will be standing by and serving as the “assistant coach” for Artemis II as the SLS rocket, once again, takes flight and sends the first crewed Artemis mission around the Moon. “SLS has been the crowning jewel of my career, and I consider myself blessed to be a part of NASA’s history,” Bevill said.

SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

Mariner 7 Goes to Mars

Thu, 03/28/2024 - 12:52pm
NASA

55 years ago, on March 27, 1969, an Atlas-Centaur rocket launched from NASA’s Kennedy Space Center in Florida, sending Mariner 7 on its way to study Mars. Mariner 7 was the second Mars probe; Mariner 6 launched Feb. 24, 1969, to investigate Mars’ equator. Mariner 7 made a close flyby of Mars just five days after Mariner 6. Scientists were able to instruct it to take additional pictures of the south pole, which had piqued their interest during Mariner 6’s flyby.

The Mariner program launched 10 missions to explore Mercury, Venus, and Mars through flybys or orbits. These missions proved that interplanetary exploration was workable with small, low-cost spacecraft, laying the groundwork for all the deep space exploration missions that followed.

College students attend the 2023 Mission Concept kickoff event at Kennedy Space Center in Florida in May 2023. At the event students work with officials from NASA and branches of the U.S. military to learn more about creating CubeSat mission launch proposals.NASA EDGE

Eight university teams have been selected to work with NASA and the U.S. military to improve their small satellite proposals, ultimately increasing the possibility of flying their technology in space, and potentially launching their own careers in the space industry.

NASA’s CSLI (CubeSat Launch Initiative) is partnering with the U.S. Air Force and U.S. Space Force for the 2024 Mission Concept Program. Running from May through August, the program will provide students with systems engineering training for spacecraft development. The partnership aims to prepare students to work in the space industry while simultaneously enhancing small satellite expertise among faculty at U.S. universities.

A total of 34 universities applied for the 2024 session. A mix of NASA, Air Force, and contractor personnel reviewed the proposals, selecting universities based on the educational impact, university program impact and development, minority outreach and support, and relevance to NASA or the Department of Defense. Three of this year’s awardees – University of Central Florida, Florida Atlantic University, and Tarleton State University – are Minority Serving Institutions. This year’s selections are:

  • University of Central Florida, Orlando
  • University of Mississippi, Oxford
  • Florida Atlantic University, Boca Raton
  • University of North Dakota, Grand Forks
  • Valparaiso University, Valparaiso, Indiana
  • Northeastern University, Boston
  • West Virginia University, Morgantown
  • Tarleton State University, Stephenville, Texas

The teams will meet at NASA’s Kennedy Space Center in Florida for a four-day kickoff meeting in May, followed by seven weeks at the Air Force’s University Nanosatellite Program facilities in Albuquerque, New Mexico, where three students will serve as interns with the Space Dynamics Laboratory.

During the program, the students will work with small satellite experts for continuous feedback and guidance to help improve university proposals and increase those teams’ potential of being selected to fly to space as part of NASA’s CSLI or the Air Force’s nanosatellite opportunities.

Final presentations will take place in Albuquerque and, although not required, participants are encouraged to attend the Small Satellite Conference in Logan, Utah, in August. Both programs will make final selections for future flights in 2025.

The 2024 Mission Concept Program provides funding for all travel, including kickoff, final event, and in-person reviews, allowing faculty and students to formulate teams without straining university resources.

NASA uses CSLI as one if its ways to attract retain students in science, technology, engineering, and mathematics disciplines. This strengthens NASA’s and the nation’s future workforce. The initiative promotes and develops innovative technology partnerships among NASA, U.S. industry, and other sectors for the benefit of all.

Don’t Make Me Wait for April 8!

Thu, 03/28/2024 - 12:13pm

Don’t Make Me Wait for April 8!

Can’t wait to see the Moon block the Sun on April 8? Neither can we. But we have good news – if you want to see an incredible cosmic alignment, you can catch one right now! Exoplanets, asteroids, and other objects regularly pass in front of stars and block their light. Observing these events is easier than you might think – and it can be a fantastic way to contribute to NASA science.

The Baily’s Beads – the bright spots of light on the lower left of the Moon – seen here are the last rays of sunlight that shone through the low spots or valleys on the Moon’s rugged surface as the Moon made its final move over the Sun during the total solar eclipse on Aug. 21, 2017, above Madras, Oregon. Baily’s Beads will appear on the opposite side of the Moon as it begins to move away from the Sun following totality. NASA/Aubrey Gemignani

There are three main kinds of cosmic alignments that temporarily block our view of a star. Each one can help us pick out fine details about astronomical objects that can’t be observed any other way.

Eclipse – when one object blocks another that’s apparently similar in size.

Occultation – when a relatively big object completely blocks an apparently smaller object.

Transit – when an apparently small object passes in front of a larger star, blocking some but not all of its light.

You’ll notice that we use the word “apparently” in each of those definitions. That’s because what matters is how big the object looks from our perspective, not how big it actually is.

Now let’s look at some science projects you can get involved in that observe these phenomena.

Eclipses help scientists see faint objects next to bright objects. Just like you might raise your hand to block light from your car’s headlight while you search the ground for your keys, eclipses block the overpowering light from a star so objects around it can be viewed more easily. This is what the Eclipse Megamovie project, the Dynamic Eclipse Broadcast Initiative, and Citizen CATE 2024 are doing: taking advantage of the Moon blocking the fierce sunlight so they can see what’s happening right around the Sun. These projects invite you to help them use this method to study the Sun’s faint corona. Eclipses and occultations can also tell us about the relative sizes and shapes of objects. This is how Sunsketcher will harness the April 8 eclipse. With your help, they will use our precise knowledge of the size and topography of the Moon to vastly improve estimates of the shape of the Sun. At the very beginning and end of totality, viewers will see Baily’s Beads – bright spots of light around the Moon’s edge where rays of sunlight slip through the valleys between the mountains on the Moon’s surface just before and after totality. The SunSketcher app will capture images of these beads along with precise time and location data of each observation. Following the eclipse, the SunSketcher team will use the collected observations to calculate the shape of the Sun.

When a planet passes directly between a star and its observer – what astronomers call a transit – the planet dims the star’s light by a measurable amount. The graph in the lower left shows a real time visualization of the strength of the light signal from the star.
NASA

When an object transits – or passes in front of – a star, the star’s light dims. Measuring changes in starlight to search for these transits has revealed thousands of exoplanets (planets orbiting other stars) in recent years. You can join the search today! Three NASA citizen science projects are focused on investigating exoplanets using transits.

  • Planet Hunters TESS invites everyone to look for traces of transiting planets in the changing light of distant stars. The most promising of these signals indicate “exoplanet candidates” to be confirmed through additional observations. This project, hosted on the Zooniverse platform, can be done on a smartphone or a computer.
  • Exoplanet Watch is a community of people who use their own telescopes or a shared community robotic telescope to observe exoplanet candidates to better predict the next time the objects will transit. This project requires an internet-connected computer.
  • UNITE, like Exoplanet Watch, is a community of folks using their telescopes to observe exoplanet candidates. This community uses Unistellar telescopes, which operate on a standard, user-friendly system. The UNITE and Exoplanet Watch teams often share data and collaborate!

Whichever events you observe, or whichever projects you choose to contribute to, we’re sure you’ll find yourself marveling at our presence on this wonderful planet in this mysterious universe. You don’t have to wait until April 8!

Three-Year Study of Young Stars with NASA’s Hubble Enters New Chapter

Three-Year Study of Young Stars with NASA’s Hubble Enters New Chapter

In the largest and one of the most ambitious Hubble Space Telescope programs ever executed, a team of scientists and engineers collected information on almost 500 stars over a three-year period. This effort offers new insights into the stars’ formation, evolution, and impact on their surroundings. 

This comprehensive survey, called ULLYSES (Ultraviolet Legacy Library of Young Stars as Essential Standards), was completed in December 2023, and provides a rich spectroscopic dataset obtained in ultraviolet light that astronomers will be mining for decades to come. Because ultraviolet light can only be observed from space, Hubble is the only active telescope that can accomplish this research. 

The ULLYSES program studied two types of young stars: super-hot, massive, blue stars and cooler, redder, less massive stars than our Sun. The top panel is a Hubble Space Telescope image of a star-forming region containing massive, young, blue stars in 30 Doradus, the Tarantula Nebula. Located within the Large Magellanic Cloud, this is one of the regions observed by ULLYSES. The bottom panel shows an artist’s concept of a cooler, redder, young star that is less massive than our Sun. This type of star is still gathering material from its surrounding, planet-forming disk.

“I believe the ULLYSES project will be transformative, impacting overall astrophysics – from exoplanets, to the effects of massive stars on galaxy evolution, to understanding the earliest stages of the evolving universe,” said Julia Roman-Duval, Implementation Team Lead for ULLYSES at the Space Telescope Science Institute (STScI) in Baltimore, Maryland. “Aside from the specific goals of the program, the stellar data can also be used in fields of astrophysics in ways we can’t yet imagine.”

The ULLYSES team studied 220 stars, then combined those observations with information from the Hubble archive on 275 additional stars. The program also included data from some of the world’s largest, most powerful ground-based telescopes and X-ray space telescopes. The ULLYSES dataset is made up of stellar spectra, which carry information about each star’s temperature, chemical composition, and rotation. 

One type of stars studied under ULLYSES is super-hot, massive, blue stars. They are a million times brighter than the Sun and glow fiercely in ultraviolet light that can easily be detected by Hubble. Their spectra include key diagnostics of the speed of their powerful winds. The winds drive galaxy evolution and seed galaxies with the elements needed for life. Those elements are cooked up inside the stars’ nuclear fusion ovens and then injected into space as a star dies. ULLYSES targeted blue stars in nearby galaxies that are deficient in elements heavier than helium and hydrogen. This type of galaxy was common in the very early universe. “ULLYSES observations are a stepping stone to understanding those first stars and their winds in the universe, and how they impact the evolution of their young host galaxy,” said Roman-Duval.  

The other star category in the ULLYSES program is young stars less massive than our Sun. Though cooler and redder than our Sun, in their formative years they unleash a torrent of high-energy radiation, including blasts of ultraviolet light and X-rays. Because they are still growing, they are gathering material from their surrounding planet-forming disks of dust and gas. The Hubble spectra include key diagnostics of the process by which they acquire their mass, including how much energy this process releases into the surrounding planet-forming disk and nearby environment. The blistering ultraviolet light from young stars affects the evolution of these disks as they form planets, as well as the chances of habitability for newborn planets. The target stars are located in nearby star-forming regions in our Milky Way galaxy.

The ULLYSES concept was designed by a committee of experts with the goal of using Hubble to provide a legacy set of stellar observations. “ULLYSES was originally conceived as an observing program utilizing Hubble’s sensitive spectrographs. However, the program was tremendously enhanced by community-led coordinated and ancillary observations with other ground- and space-based observatories,” said Roman-Duval. “Such broad coverage allows astronomers to investigate the lives of stars in unprecedented detail and paint a more comprehensive picture of the properties of these stars and how they impact their environment.”

To that end, STScI hosted a ULLYSES workshop March 11–14 to celebrate the beginning of a new era of research on young stars. The goal was to allow members of the astronomical community to collaborate on the data, so that they could gain momentum in the ongoing analyses, or kickstart new ideas for analysis. The workshop was one important step in exploiting this legacy spectral library to its fullest potential, fulfilling the promise of ULLYSES.

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 and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. 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.

NASA Astronaut Loral O’Hara, Expedition 70 Science Highlights

Thu, 03/28/2024 - 10:00am

4 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA astronaut Loral O’Hara is returning home after six months aboard the International Space Station. During her time on the orbiting laboratory, O’Hara contributed to dozens of scientific investigations and technology demonstrations to prepare for future space exploration missions and generate innovations and benefits for humanity on Earth.

Here is a look at some of the scientific activities O’Hara conducted during her mission:

Biking for Better Health NASA

NASA astronaut Loral O’Hara is among the first astronauts participating in the CIPHER (Complement of Integrated Protocols for Human Exploration Research on Varying Mission Durations) investigation. CIPHER examines physiological and psychological changes that humans undergo during spaceflight. One of the protocols measures changes in cardiorespiratory and muscle fitness during exercise. Collecting data from crew members on missions of different durations supports development of ways to protect crew member health on a long mission such as a trip to Mars.

Tending the Space Garden NASA

NASA astronaut Loral O’Hara works with tomato plants grown for Plant Habitat-06, an investigation using genetic analysis to examine how spaceflight affects plant immune function and production. Results could support development of crops to provide food and other services on future space missions. On Earth, pathogens are responsible for up to 40% of global crop loss, and insight into the interaction between gravity and how plants respond to pathogens could inform strategies to enhance crop growth and productivity.

Reading Radiation Exposure NASA

Crew members pose with active dosimeters: left to right, Andreas Mogensen of ESA (European Space Agency), NASA astronauts Loral O’Hara and Jasmin Moghbeli, and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency). These devices monitor individual radiation exposure for the International Space Station Internal Radiation Monitoring investigation, which aims to keep ionizing radiation exposure at levels acceptable for maintaining crew member health and safety and ensuring the success of their missions.

Understanding Bone Loss NASA

Bone loss is a major problem of aging on Earth and a serious health concern for astronauts. MABL-A (Microgravity Associated Bone Loss-A) examines the effect of microgravity on bone marrow mesenchymal stem cells, which produce bone-forming cells and play a role in making and repairing skeletal tissues. NASA astronaut Loral O’Hara works inside the Life Science Glovebox for the investigation, which could improve understanding of the mechanisms behind bone loss and support development of ways to better protect crew members and people on Earth from its effects.

Bringing in the Cold NASA

NASA astronauts Jasmin Moghbeli and Loral O’Hara pose in front of the Cold Atom Lab. The lab produces clouds of atoms so cold that they have almost no motion, allowing researchers to observe their fundamental behaviors and quantum characteristics. Physicists have long pursued ever colder temperatures, and microgravity may make it possible to achieve those temperatures for longer periods of time. The Cold Atom Lab research could facilitate the development of new quantum technology.

Taking Out the Heat NASA

NASA astronaut Loral O’Hara works on MaRVIn-PCIM (Microgravity Research for Versatile Investigations-Phase Change in Mixtures), which examines the dynamics of liquid and vapor flow inside a wickless heat pipe. These devices, used to dissipate heat to cool satellites and electronics, operate differently in microgravity than on Earth. Results could support development of lighter and more efficient cooling devices for future space exploration.

Preparing for a Walk in Space NASA

NASA astronaut Loral O’Hara tests components of her spacesuit in preparation for a spacewalk. O’Hara and NASA astronaut Jasmin Moghbeli conducted a spacewalk together on Nov 1, 2023. It took the duo six hours and 42 minutes to complete tasks that included working on hardware that enables the space station’s solar arrays to track the Sun, helping to provide power for scientific operations on the orbiting lab.

Creating Cardiac Tissues NASA

NASA astronaut Loral O’Hara works on the Redwire Cardiac Bioprinting Investigation (BFF Cardiac), which studies bio-printed cardiac tissues. Higher-quality 3D tissues can be printed in microgravity, where density layers, settling, and other effects of gravity are absent. This technology supports development of ways to print food and medicine on demand on future missions, reducing mass and cost at launch and improving crew health and safety. Results also could advance technologies to create replacement organs and tissues for transplant on Earth, helping to alleviate shortages.

Rep. Weldon Statement on the Space Shuttle Columbia Accident

Kennedy Space Center, FL —U.S. Congressman Dave Weldon (FL-15) released the following statement in the wake of the Space Shuttle Columbia accident.

I mourn the loss of 7 brave men and women today. These dedicated pioneers — Commander -Rick Husband, Pilot-William McCool, Payload Commander – Michael Anderson, Specialist – Kalpana Chawla, Specialist – David Brown, Specialist – Laurel Clark and Specialist – Ilan Ramon — gave their lives in the name of science and exploration. This is a tragic day for America, for Israel, and for the world and we will forever be in their debt.

While we must learn the cause of this tragedy, and I know NASA will be working diligently to do so, we must not let this deter our exploration efforts. We should never retreat from our progress in space exploration.

We will reevaluate, however, how we conduct our human space flight operations, we will reexamine our processes, and we will learn how to make space flight safer. Then we will return to space. I believe the crew of Columbia would expect nothing less.

“I would ask all Americans, and, indeed, everyone around the world, to keep the families, friends, and colleagues of these heroic astronauts in your thoughts and prayers. Their contribution to opening the frontier will not be forgotten,” said Rep. Weldon.

During his fourth mission to the International Space Station, NASA astronaut Don Pettit will serve as a flight engineer and member of the Expedition 71/72 crew. After blasting off to space, Pettit will conduct scientific investigations and technology demonstrations to help prepare crew for future space missions.

Pettit will launch on the Roscosmos Soyuz MS-26 spacecraft in September 2024, accompanied by Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. The trio will spend approximately six months aboard the orbital laboratory.

NASA selected Pettit as an astronaut in 1996. A veteran of three spaceflights, he made integral advancements in technology and demonstrations for human exploration. He served as a science officer for Expedition 6 in 2003, operated the robotic arm for STS-126 space shuttle Endeavour in 2008, and served as a flight engineer for Expedition 30/31 in 2012. Pettit has logged 370 days in space and conducted two spacewalks totaling 13 hours and 17 minutes.

The Expedition 6 crew launched on STS-113 space shuttle Endeavour expecting to return on STS-114 space shuttle Discovery after a two and a half month mission. Following the space shuttle Columbia accident that grounded the shuttle fleet, the crew returned on the Soyuz TMA-1 spacecraft after five and a half months, landing in Kazakhstan. On his next 16-day mission, STS-126, Pettit helped expand the living quarters of the space station and installed a regenerative life support system to reclaim potable water from urine. During Expedition 30/31, Pettit also captured the first commercial cargo spacecraft, the SpaceX Dragon, using the robotic arm.

A native from Silverton, Oregon, Pettit holds a bachelor’s degree in chemical engineering from Oregon State University, Corvallis, and a doctorate in chemical engineering from the University of Arizona, Tucson. Prior to his career with NASA, Pettit worked as a staff scientist at the Los Alamos National Laboratory in New Mexico.

For more than two decades, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to focus more of its resources on deep space missions to the Moon and Mars.

Take 5 with Mitzi Adams

By Wayne Smith

Mitzi Adams watched several astronauts walk on the Moon when she was a teenager during NASA’s Apollo missions. That’s when Adams realized she wanted to be a NASA scientist. She also envisioned having an office on the lunar surface by 2000.

Today, Adams is a NASA scientist at the agency’s Marshall Space Flight Center. She is the assistant manager of the Heliophysics and Planetary Science branch of the Science and Technology Office. And while she doesn’t have an office on the Moon, she does see a path for future scientists and explorers to reach that destination.

“We are on the cusp of landing another human on the Moon for the first time in more than 50 years,” said Adams, who has worked at NASA for 35 years. “This time, however, there is a desire for a sustained presence, as well as a renewed interest in scientific research and discovery. If I were a high school student today, I feel that there would be a high probability that at least one of my offices would be located on the Moon in the not-too-distant future. There are many possibilities for this generation of students to be heavily involved in human space exploration. This is truly exciting.”

Heliophysics encompasses the study of the Sun and its effects on Earth, the solar system, and space itself. With the focus on the upcoming total solar eclipse April 8, Adams said participating and organizing NASA outreach events for the 2017 eclipse is one of the proudest moments of her career.

“We partnered with the city of Hopkinsville, Kentucky, Austin Peay State University, the U.S. Space & Rocket Center, and The INSPIRE Project to involve high school students and the public in observations and science experiments surrounding the 2017 solar eclipse,” said Adams, who is from Atlanta, Georgia. “We presented science topics to the students and allowed them to choose their observation site, based on their interests. In the intervening years since the eclipse, those INSPIRE Project students have been extremely successful, both in academics and in the business world. One of those students graduated from the Air Force Academy in 2022. That student is currently in flight school and expects to earn her wings in the next couple of months. We like to think that we were a positive influence on her and that the eclipse inspired her to obtain a STEM degree.”         

Question: What excites you most about the future of human space exploration, or your NASA work, and your team’s role it?

Adams: For the safety of astronauts who will remain on the surface of a world devoid of a protective atmosphere, as well as when traveling between the Earth and the Moon (or Mars), it is imperative that we understand better the Sun and space weather. To date, through a fleet of spacecraft studying the Sun, we have made great strides in nowcasting solar events, such as flares and coronal-mass ejections. In addition, through a sounding-rocket program, our scientists have contributed to basic knowledge of solar physics and are beginning to unravel the puzzle surrounding magnetic-reconnection events in the solar atmosphere that may be causing flares and coronal-mass ejections.

Question: Who or what drives/motivates you?

Adams: Many things. As a teenager, I was inspired by Edgar Mitchell, lunar-module pilot on Apollo 14, whom I met and pestered throughout his life. He never discouraged me from my goals and always encouraged. I have always been a science fiction fan. I think my first science fiction book as a third-grade student was “Have Space Suit – Will Travel,” by Robert Heinlein. So, it was only natural that I became a Star Trek fan. From Star Trek, I was inspired by Nichelle Nichols, who played Lt. Uhura, and Leonard Nimoy, who played Mr. Spock, a science officer. 

When I speak to students, I ask what they think is the most important attribute of a scientist. The answer I seek from them is curiosity – puzzles and mysteries drive and motivate me. Observing the Sun, I have seen eruptions and phenomena that I want to understand, which drives me to access those data and do the analysis! 

Question: Who or what inspired you to pursue an education/career that led you to NASA and Marshall?

Adams: I’ve always wanted to be a scientist and I could have studied geology or astronomy. Since becoming an astronaut also was a goal, I decided that astronomy would be the best path. Specifically, as I was about to obtain my undergraduate degree from Georgia State University, I thought I needed internship experience. Since one of my caving friends, Joe Dabbs, worked at Marshall, I asked if he knew anyone who might need a summer student. Joe put me in touch with Ron Moore with NASA and Gordon Emslie of the University of Alabama in Huntsville (UAH), who hired me for the summer. They apparently were pleased with my work because they suggested I apply to UAH for graduate school and to the graduate co-op program. I was accepted by both and earned a master’s degree in physics from UAH, after which I was hired by Marshall as a research scientist in solar physics.  

Question: What advice do you have for employees early in their NASA career or those in new leadership roles?

Adams: Networking is important. Engage with colleagues at meetings and seek out collaborations. Read research papers and contact those scientists who are included in the references list. Don’t be intimidated by scientists who have a lot of experience. If a problem/question in your research world is appealing, find ways you can contribute to finding solutions and ask the first or second author scientist if you can help.      

Question: What do you enjoy doing with your time while away from work?

Adams: Believe it or not, I enjoy reading Latin in small doses and have read two of the Harry Potter books in Latin, with help from two friends. I also enjoy hiking on trails, playing with my 3-year-old white Shepherd named Albus, which means white in Latin, and reading and watching science fiction.

Shuttle, Family Inspire NASA’s Cryogenic Technology Manager

By Daniel Boyette

Jeremy Kenny squinted his eyes as he looked toward the brilliant light. Then came the deafening sound waves that vibrated his body. This was the moment he’d dreamed about since childhood.

It was Nov. 16, 2009, at NASA’s Kennedy Space Center, and Kenny and his wife were watching space shuttle Atlantis embark on a mission to the International Space Station. Kenny, who was less than two years into his NASA career, had the opportunity to see the liftoff from Launch Pad 39A as part of receiving the Space Flight Awareness Award for supporting the Space Shuttle Program’s solid rocket booster flight program.

Jeremy Kenny, manager of NASA’s Cryogenic Fluid Management Portfolio Project, holds a model spacecraft for the proposed large cryogenic demonstration mission. The mission aims to demonstrate liquid hydrogen management, including near-zero propellant boil off and highly efficient propellant transfer, needed to achieve long-duration transit to/from Mars and spacecraft loitering during on-surface campaigns.Credit: NASA/Danielle Burleson

“That was the first launch I ever witnessed in person,” said Kenny, whose inspiration for working at NASA came from watching televised shuttle launches as a youth. “It was amazing and made me appreciate how such a powerful system could be designed and flown so successfully.”

With the final shuttle mission two years later, NASA set its sights on designing and building its future Artemis rocket: SLS (Space Launch System). Kenny was selected to lead the SLS Modal Acoustic Test program, which helped engineers understand how loud the rocket would be during liftoff. He later joined another key Artemis effort, the human landing system program, as a technical manager, overseeing the development of lander systems that will transport astronauts to the Moon’s surface.

“Artemis is an inspiring campaign for future human spaceflight exploration,” Kenny said. “I worked with SLS, Orion, and Exploration Ground Systems, and it was very fulfilling to see all the pieces come together for the successful Artemis I launch.”

In January, Kenny was named manager of NASA’s Cryogenic Fluid Management (CFM) Portfolio project, where he oversees a cross-agency team based at NASA’s Marshall Space Flight Center and Glenn Research Center. The CFM portfolio includes innovative technologies to store, transfer, and measure ultra-cold fluids – such as liquid hydrogen, liquid oxygen, and liquid methane. These cryogens are the most common propellants in space exploration, making CFM integral to NASA’s future exploration and science efforts.

“We must mature CFM technologies to support future flight mission architectures,” said Kenny. “The strong partnership between Marshall and Glenn in CFM maturation continues to produce excellent results, enabling in-space cryogenic systems vital to NASA’s Moon to Mars vision.”

Kenny’s choice of profession comes as little surprise, given his family background. He had a grandfather and an uncle who worked with the U.S. Army Corps of Engineers in the family’s hometown of Vicksburg, Mississippi. From them, Kenny learned how math and physics could be implemented in real-world applications. He earned three degrees in mechanical engineering: a bachelor’s from Mississippi State University in Starkville, a master’s from Georgia Tech in Atlanta, and a doctorate from the University of Alabama in Huntsville.

“My grandfather showed me various engineering software programs he worked on to simulate ground terrains for military transportation systems,” Kenny said. “My uncle worked on engineering developments for various military systems; he was a key influence for me to pursue graduate degrees in mechanical engineering.”

When Kenny’s not working to evolve technology for NASA’s future deep space exploration missions, he’s spending time with his wife and their two daughters, who are involved in choir and dance.

“Watching them practice and perform inspires me,” Kenny said with a smile. “My biggest challenge is balancing my professional work, which I love, and spending time with my family, who I love. With work comes many exciting opportunities, and solving hard problems is fun. But that excitement should not detract from keeping your personal relationships healthy. One day, I’ll retire and spend all my free time with family.”

The CFM Portfolio Project’s work is under NASA’s Technology Demonstration Missions Program, part of NASA’s Space Technology Mission Directorate, which oversees a broad portfolio of technology development and demonstration projects across NASA centers and American industry partners.

NASA Continues Artemis Moon Rocket Engine Tests

NASA continued a key RS-25 engine test series for future Artemis flights of the agency’s powerful SLS (Space Launch System) rocket March 22 and March 27 with hot fires on the Fred Haise Test Stand at NASA’s Stennis Space Center.

The tests marked the 10th and 11th hot fire in a 12-test series to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3 Harris Technologies company.

On March 22, the Stennis test team fired the certification engine for 500 seconds, or the same amount of time engines must fire to help launch the SLS rocket to space with astronauts aboard the Orion spacecraft. Operators powered the engine up to a level of 113%, which is beyond the 111% power level new RS-25 engines use to provide additional thrust. Testing up to the 113% power level provides a margin of operational safety.

Newly produced engines will power NASA’s SLS rocket on Artemis missions to the Moon and beyond, beginning with Artemis V. For Artemis missions I-IV, NASA and Aerojet Rocketdyne modified 16 former space shuttle engines for use on the SLS rocket. Four RS-25 engines fire simultaneously to help launch each SLS rocket, producing up to 2 million pounds of combined thrust.

Payload Adapter Testing: A Key Step for Artemis IV Rocket’s Success

A test article of the SLS (Space Launch System) rocket’s payload adapter is ready for evaluation, marking a critical milestone on the journey to the hardware’s debut on NASA’s Artemis IV mission.

Comprised of two metal rings and eight composite panels, the cone-shaped payload adapter will be part of the SLS Block 1B configuration and housed inside the universal stage adapter atop the rocket’s more powerful in-space stage, called the exploration upper stage. The payload adapter is an evolution from the Orion stage adapter used in the Block 1 configuration of the first three Artemis missions that sits at the topmost portion of the rocket and helps connect the rocket and spacecraft.

Key adapters for the first crewed Artemis missions are manufactured at NASA’s Marshall Space Flight Center. The cone-shaped payload adapter, left, will debut on the Block 1B configuration of the SLS rocket beginning with Artemis IV, while the Orion stage adapters, right, will be used for Artemis II and Artemis III.NASA/Sam Lott

“Like the Orion stage adapter and the launch vehicle stage adapter used for the first three SLS flights, the payload adapter for the evolved SLS Block 1B configuration is fully manufactured and tested at NASA’s Marshall Space Flight Center,” said Casey Wolfe, assistant branch chief for the advanced manufacturing branch at Marshall. “Marshall’s automated fiber placement and large-scale integration facilities provide our teams the ability to build composite hardware elements for multiple Artemis missions in parallel, allowing for cost and schedule savings.”

At about 8.5 feet tall, the payload adapter’s eight composite sandwich panels, which measure about 12 feet each in length, contain a metallic honeycomb-style structure at their thickest point but taper to a single carbon fiber layer at each end. The panels are pieced together using a high-precision process called determinant assembly, in which each component is designed to fit securely in a specific place, like puzzle pieces.

Teams at Marshall manufactured, prepared, and moved the payload adapter test article. The payload adapter will undergo testing in the same test stand that once housed the SLS liquid oxygen tank structure test article.NASA

After manufacturing, the payload adapter will also be structurally tested at Marshall, which manages the SLS Program. The first structural test series begins this spring. Test teams will use the engineering development unit – an exact replica of the flight version of the hardware – to check the structure’s strength and durability by twisting, shaking, and applying extreme pressure.

While every Block 1B configuration of the SLS rocket will use a payload adapter, each will be customized to fit the mission’s needs. The determinant assembly method and digital tooling ensure a more efficient and uniform manufacturing process, regardless of the mission profile, to ensure hardware remains on schedule. Data from this test series will further inform design and manufacturing processes as teams begin manufacturing the qualification and flight hardware for Artemis IV.

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.

Chandra Identifies an Underachieving Black Hole

A new image shows a quasar, a rapidly growing supermassive black hole, which is not achieving what astronomers would expect from it, as reported in a press release. Data from NASA’s Chandra X-ray Observatory (blue) and radio data from the NSF’s Karl G. Jansky’s Very Large Array (red) reveal some of the evidence for this quasar’s disappointing impact on its host galaxy.

Known as H1821+643, this quasar is about 3.4 billion light-years from Earth. Quasars are a rare and extreme class of supermassive black holes that are furiously pulling material inwards, producing intense radiation and sometimes powerful jets. H1821+643 is the closest quasar to Earth in a cluster of galaxies.

This composite image shows a quasar, a rare and extreme class of supermassive black hole. Known as H1821+643, this quasar is about 3.4 billion light-years from Earth.X-ray: NASA/CXC/Univ. of Nottingham/H. Russell et al.; Radio: NSF/NRAO/VLA; Image Processing: NASA/CXC/SAO/N. Wolk

Quasars are different than other supermassive black holes in the centers of galaxy clusters in that they are pulling in more material at a higher rate. Astronomers have found that non-quasar black holes growing at moderate rates influence their surroundings by preventing the intergalactic hot gas from cooling down too much. This regulates the growth of stars around the black hole.

The influence of quasars, however, is not as well known. This new study of H1821+643 that quasars – despite being so active – may be less important in driving the fate of their host galaxy and cluster than some scientists might expect.

To reach this conclusion the team used Chandra to study the hot gas that H1821+643 and its host galaxy are shrouded in. The bright X-rays from the quasar, however, made it difficult to study the weaker X-rays from the hot gas. The researchers carefully removed the X-ray glare to reveal what the black hole’s influence is, which is reflected in the new composite image showing X-rays from hot gas in the cluster surrounding the quasar. This allowed them to see that the quasar is actually having little effect on its surroundings.

Using Chandra, the team found that the density of gas near the black hole in the center of the galaxy is much higher, and the gas temperatures much lower, than in regions farther away. Scientists expect the hot gas to behave like this when there is little or no energy input (which would typically come from outbursts from a black hole) to prevent the hot gas from cooling down and flowing towards the center of the cluster.

A paper describing these results has been accepted into the Monthly Notices of the Royal Astronomical Society and is available online. The authors are Helen Russell (University of Nottingham, UK), Paul Nulsen (Center for Astrophysics | Harvard & Smithsonian), Andy Fabian (University of Cambridge, UK), Thomas Braben (University of Nottingham), Niel Brandt (Penn State University), Lucy Clews (University of Nottingham), Michael McDonald (Massachusetts Institute of Technology), Christopher Reynolds (University of Maryland), Jeremy Saunders (Max Planck Institute for Extraterrestrial Research), and Sylvain Veilleux (University of Maryland).

OSIRIS-REx Mission Awarded Robert Goddard Memorial Trophy

NASA’s OSIRIS-REx team was selected as the winner of the National Space Club and Foundation’s 2024 Dr. Robert H. Goddard Memorial Trophy for their tremendous work on the first U.S. mission to bring an asteroid sample to Earth. The winning team received the award at the 67th Annual Robert H. Goddard Memorial Dinner at the Washington Hilton Hotel on March 22.

The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) team includes NASA’s Goddard Space Flight Center, Maryland; Lockheed Martin in Littleton, Colorado; University of Arizona, Tucson and KinetX in Tempe, Arizona.

The sample return capsule from NASA’s OSIRIS-REx mission is seen shortly after touching down in the desert Sept. 24, 2023, at the Department of Defense’s Utah Test and Training Range. The sample was collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft.NASA/Keegan Barber

The trophy is National Space Club’s highest honor and presented annually to the individual or group who has made a substantial contribution to U.S. leadership in astronautics or rocketry.

“The OSIRIS-REx team’s successful delivery of the asteroid Bennu sample to Earth will enable important scientific discoveries for generations to come,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters. “I’m so pleased to see the mission team recognized with the Robert H. Goddard Memorial Trophy for their accomplishments.”

Following its launch in 2016, the OSIRIS-REx mission made U.S. space history when it became the first U.S. spacecraft to touch an asteroid and capture a sample on Oct. 20, 2020, and again when it successfully returned with the sample to Earth on Sept. 24, 2023.

The sample, which is the largest asteroid sample ever delivered to Earth, is from the ancient asteroid Bennu and will give researchers worldwide a glimpse into the earliest days of our solar system, offering insights into planet formation and the origin of organics that led to life on Earth. Data collected by the spacecraft combined with future analysis of the Bennu sample will also aid our understanding of asteroids that can impact Earth.

The OSIRIS-REx mission conducted unprecedented centimeter-scale mapping of Bennu, surpassing precision levels achieved for any other planetary body and setting three Guinness World Records for: smallest object orbited by a spacecraft, closest orbit of an asteroid and highest resolution satellite map of any planetary body.

“The OSIRIS-REx mission rewrote U.S. space exploration history,” said Joe Vealencis, president, NSCF. “The data the spacecraft collected, plus all that we have yet to uncover from the sample it brought back, means scientists and engineers will be reaping the benefits of this mission for years to come.”

Following its successful sample return, the OSIRIS-REx spacecraft was renamed OSIRIS-APEX and will now enter an extended mission to visit and study near-Earth asteroid Apophis in 2029.

OSIRIS-REx’s success was made possible by the unique contributions of over 1,000 individuals from government and mission partners like the science lead at the University of Arizona, the project team at NASA’s Goddard Space Flight Center, the curation team at NASA’s Johnson Space Center, spacecraft design, operations, and recovery by Lockheed Martin, guidance and navigation at KinetX, and the launch provider at United Launch Alliance.

OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center for the Science Mission Directorate at NASA Headquarters.

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

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 interim cryogenic propulsion stage (ICPS), 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. “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.

Eclipse Citizen Science for Educators

“Citizen” here refers to citizens of Planet Earth. These projects are open to everyone, regardless of country of birth or legal citizenship status.

If you are not already familiar with NASA’s citizen science opportunities or specific projects related to the April 8 solar eclipse, we encourage you to read Contribute to NASA Research on Eclipse Day – and Every Day.

Jeffrey Bouwman at work in his classroom. Mr. Bouwman has long used citizen science projects in his classroom. Learn more about Mr. Bouwman in his NASA citizen scientist profile. Jeffrey Bouwman

Citizen science projects – research projects that need lots of people and are designed for participation by anyone – are a great way for formal and informal students and enthusiasts to learn science by doing it. There are a number of these participatory projects addressing a wide variety of research questions. These projects have a range of difficulty, training requirements, time requirements, and equipment – in short, there really is a project for everyone!

Finding Your First Project

Choosing a project that’s right for your students or informal learners begins with choosing a project that works for you. Use the tables here to identify some projects that have the appropriate timing, challenge level, and equipment (or lack thereof!) that are right for you and your learners. If you have never contributed to a participatory or citizen science project, it’s a great idea to start with a simple project that doesn’t require a lot of equipment.

Here are a few suggestions for getting started:

  1. Review the project descriptions to help choose the best one for you. Whittle your choice down to 1 or 2 projects. If you need a day-of-eclipse project, pick a second one that you can do anytime as a practice project for yourself.
  2. Do the project yourself. If you want to do a day-of eclipse project that is not yet available, pick another project to practice with. It will give you a sense of how these opportunities are structured and what it might feel like for your learners to participate. Read the project website, complete the preparation or training materials, and do the task enough to get a feel for what’s involved, what’s tricky, and what’s fun or satisfying about it. You don’t need to master the project or solve all problems that might arise. Do it until you have a sense for what participation feels like and what learning opportunities the project or task includes.
  3. When you introduce the project to your learners, emphasize that this is a real chance to do scientific research alongside other interested people around the world and with the professional team leading the project. Don’t hesitate to remind them that this is a NASA project working with NASA scientists!
  4. Are you an informal educator? Incorporate a citizen science project into an existing program with a small and/or familiar audience, or recruit a small group of volunteers or docents to try it with you. Set clear expectations (“we’ll be learning this together!”) and go for it. You will learn more about how to lead others through a project by trying it than any other way. Adjust your approach as you learn.
  5. Are you a formal educator? Start small by asking for volunteers to try the project out with you after school or during a study hall. Or pick a class and just go for it. You will learn the most about how to use and facilitate citizen science projects in your classroom by simply doing one. Adjust your approach as you and your students learn.

And thank you for participating!

Diez maneras en que los estudiantes pueden prepararse para ser astronautas

Wed, 03/27/2024 - 2:07pm

¿Quieres ser astronauta, pero no sabes por dónde empezar? ¡Estas son algunas maneras en las que puedes comenzar tu viaje! Incluso si no aún no reúnes los requisitos para ser astronauta, mediante la Oficina de Participación STEM (ciencia, tecnología, ingeniería y matemáticas) de la NASA, u OSTEM, hay formas de participar en las misiones de la NASA. Echa un vistazo a las 10 mejores maneras de ser astronauta:

1. Solicita una pasantía en la NASA.

Convertirse en pasante es la manera perfecta de comenzar con la NASA. ¡Varios astronautas comenzaron como pasantes! La astronauta recién estrenada Jessica Watkins fue seleccionada como pasante de la NASA mientras era estudiante de pregrado y posgrado. “Esas experiencias fueron realmente las que me ayudaron a formarme como científica y exploradora”, dijo Watkins, atribuyéndolo a las experiencias prácticas de las que tuvo la oportunidad de ser parte durante sus pasantías. ¿Te interesa participar? Puedes encontrar más información en: intern.nasa.gov

2. Participa en los desafíos estudiantiles de Artemis.

¿Sabías que los Desafíos estudiantiles de Artemis (en inglés) contribuyen directamente a la misión de la NASA? El Reto estudiantil para lanzamientos suborbitales, el Desafío del rover de exploración humana, la Tecnología de interfaz del usuario de trajes espaciales para estudiantes (SUITS, por sus siglas en inglés), los Lunabotics, los Equipos de diseño experimental de flotación neutra microgravedad (Micro-G NExT, por sus siglas en inglés), El Reto de sistemas de lanzamiento para las Naciones Originarias y el Reto estudiantil Big Idea (Gran Idea) varían según la misión y el nivel académico (desde la escuela intermedia a la universidad) y abarcan muchos elementos del programa Artemis. Los desafíos estudiantiles de Artemis te permiten ser creativo, tomar lo que has aprendido en el aula y aplicarlo a los desafíos existentes para la exploración espacial.

3. Suscríbete a NASA EXPRESS.

¡Mantente informado sobre lo que sucede dentro de la NASA! NASA EXPRESS es un boletín semanal (en inglés) que ofrece novedades y oportunidades de la NASA y de la comunidad de Participación en STEM. NASA EXPRESS es un gran recurso para que los estudiantes exploren diversas oportunidades en STEM más allá de las paredes del aula. ¡Suscríbete hoy!

4. Asiste al ASTRO CAMP® o al Campamento Espacial.

¿Eres un joven explorador? Mejora tus destrezas en el ASTRO CAMP® en el Centro Espacial Stennis de la NASA. La astronauta de la NASA Kate Rubins viajó a la Estación Espacial Internacional en 2016, pero antes de eso asistió al Campamento Espacial cuando cursaba séptimo grado, después de ahorrar el dinero que le pagaban por hacer tareas domésticas para poder asistir. Rubins soñaba con convertirse en astronauta cuando era niña y dejó el campamento sabiendo que tenía que tomar tantos cursos de matemáticas y ciencias como pudiera para hacer realidad su sueño.

5. ¡Aprende lo que realmente se necesita para convertirte en astronauta!

Existen muchos mitos y conceptos erróneos sobre lo que se necesita para ser astronauta. Infórmate sobre los hechos y los requisitos, y prepárate para una experiencia fuera de este mundo, literalmente.

6. Una gran variedad de carreras profesionales pueden llevarte al espacio: ¡Encuentra una que te guste!

¡Mantén una mentalidad abierta! No tienes que ser ingeniero o seguir un camino específico para ser astronauta. Los astronautas de la NASA provienen de todos los ámbitos de la vida: maestros, médicos, biólogos, geólogos, militares… ¡y más! La cohorte de astronautas más reciente refleja este nivel de diversidad. Por encima de todo, asegúrate de que amas lo que haces.

7. Mantente activo.

La aptitud física es una gran parte del entrenamiento de los astronautas y de la vida diaria en el espacio. A bordo de la Estación Espacial Internacional, los astronautas se ejercitan dos horas al día para mantener sus huesos fuertes en el entorno de microgravedad. Mantén un estilo de vida saludable y un régimen de ejercicios, ¡o prueba un nuevo deporte! Encuentra más información (en inglés) sobre cómo los astronautas se mantienen en forma aquí.

8. Participa en ferias de ciencias e ingeniería.

Tómate el tiempo para mostrar tu arduo trabajo e ingenio fuera del aula. Las ferias de ciencias e ingeniería son una excelente manera no solo de mostrar tu trabajo, sino también de inspirarte en las personas que te rodean.

9. Postúlate a escuelas de posgrado y de capacitación profesional, o a un programa de entrenamiento para pilotos.

Planifica tu futuro. Si quieres ser astronauta, es imprescindible obtener un título académico avanzado. Los astronautas deben completar una maestría en un campo de STEM, trabajar para obtener un doctorado o tener un doctorado en medicina o una licenciatura en medicina osteopráctica. Postúlate para una escuela de posgrado y da un paso adelante en tu educación, preparándote para la vida en el espacio. Otra forma de calificar es mediante la realización de un programa como piloto de pruebas en una institución acreditada.

10. Inscríbete en clases y clubes de STEM.

¿No estás todavía a nivel universitario o de posgrado? Nunca es demasiado pronto para involucrarte en áreas de STEM y dar los primeros pasos hacia una carrera fuera de este mundo. Elige clases de ciencias, matemáticas y programación que se alineen con tus objetivos y únete a clubes y actividades relacionadas con STEM fuera del aula. Si tu escuela o comunidad no ofrece un club para lo que te interesa, ¡crea uno!

Mientras la NASA continúa avanzando con el programa Artemis y el reclutamiento de astronautas, tú, la futura fuerza laboral de STEM que podría algún día llevarnos a mundos distantes, eres una parte importante de eso. A través de la variedad de recursos de OSTEM, puedes unirte a nosotros en este viaje mientras avanzamos hacia la Luna… y más allá.

NASA’s Europa Clipper Survives and Thrives in ‘Outer Space’ on Earth

Wed, 03/27/2024 - 11:59am

5 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) Europa Clipper is seen in the 25-Foot Space Simulator at JPL in February, before the start of thermal vacuum testing. A battery of tests ensures that the NASA spacecraft can withstand the extreme hot, cold, and airless environment of space. NASA/JPL-Caltech

A gantlet of tests prepared the spacecraft for its challenging trip to the Jupiter system, where it will explore the icy moon Europa and its subsurface ocean.

In less than six months, NASA is set to launch Europa Clipper on a 1.6-billion-mile (2.6-billion-kilometer) voyage to Jupiter’s ocean moon Europa. From the wild vibrations of the rocket ride to the intense heat and cold of space to the punishing radiation of Jupiter, it will be a journey of extremes. The spacecraft was recently put through a series of hard-core tests at the agency’s Jet Propulsion Laboratory in Southern California to ensure it’s up to the challenge.

Called environmental testing, the battery of trials simulates the environment that the spacecraft will face, subjecting it to shaking, chilling, airlessness, electromagnetic fields, and more.

NASA’s Europa Clipper is seen being lifted into the Space Simulator at JPL in February. Thermal vacuum testing, which lasted 16 days, ensures that the spacecraft will withstand the harsh conditions of space. NASA/JPL-Caltech NASA’s Europa Clipper is visible in the clean room of High Bay 1 within JPL’s Spacecraft Assembly Facility in January. The tent around the spacecraft was erected to support electromagnetic testing, which was part of a regimen of environmental tests. NASA/JPL-Caltech

“These were the last big tests to find any flaws,” said JPL’s Jordan Evans, the mission’s project manager. “Our engineers executed a well-designed and challenging set of tests that put the system through its paces. What we found is that the spacecraft can handle the environments that it will see during and after launch. The system performed very well and operates as expected.”

The Gantlet

The most recent environmental test for Europa Clipper was also one of the most elaborate, requiring 16 days to complete. The spacecraft is the largest NASA has ever built for a planetary mission and one of the largest ever to squeeze into JPL’s historic 85-foot-tall, 25-foot-wide (26-meter-by-8-meter) thermal vacuum chamber (TVAC). Known as the 25-foot Space Simulator, the chamber creates a near-perfect vacuum inside to mimic the airless environment of space.

At the same time, engineers subjected the hardware to the high temperatures it will experience on the side of Europa Clipper that faces the Sun while the spacecraft is close to Earth. Beams from powerful lamps at the base of the Space Simulator bounced off a massive mirror at its top to mimic the heat the spacecraft will endure.

To simulate the journey away from the Sun, the lamps were dimmed and liquid nitrogen filled tubes in the chamber walls to chill them to temperatures replicating space. The team then gauged whether the spacecraft could warm itself, monitoring it with about 500 temperature sensors, each of which had been attached by hand.

TVAC marked the culmination of environmental testing, which included a regimen of tests to ensure the electrical and magnetic components that make up the spacecraft don’t interfere with one another.

The orbiter also underwent vibration, shock, and acoustics testing. During vibration testing, the spacecraft was shaken repeatedly – up and down and side to side – the same way it will be jostled aboard the SpaceX Falcon Heavy rocket during liftoff. Shock testing involved pyrotechnics to mimic the explosive jolt the spacecraft will get when it separates from the rocket to fly its mission. Finally, acoustic testing ensured that Europa Clipper can withstand the noise of launch, when the rumbling of the rocket is so loud it can damage the spacecraft if it’s not sturdy enough.

“There still is work to be done, but we’re on track for an on-time launch,” Evans said. “And the fact that this testing was so successful is a huge positive and helps us rest more easily.”

Looking to Launch

Later this spring, the spacecraft will be shipped to NASA’s Kennedy Space Center in Florida. There, teams of engineers and technicians will carry out final preparations with eyes on the clock. Europa Clipper’s launch period opens Oct. 10.

After liftoff, the spacecraft will zip toward Mars, and in late February 2025, it will be close enough to use the Red Planet’s gravitational force for added momentum. From there, the solar-powered spacecraft will swing back toward Earth to get another slingshot boost – from our own planet’s gravitational field – in December 2026.

Then it’s on to the outer solar system, where Europa Clipper is set to arrive at Jupiter in 2030. The spacecraft will orbit the gas giant while it flies by Europa 49 times, dipping as close as 16 miles (25 kilometers) from the moon’s surface to gather data with its powerful suite of science instruments. The information gathered will tell scientists more about the moon’s watery interior.

More About the Mission

Europa Clipper’s main science goal is to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life. The mission’s three main science objectives are to determine the thickness of the moon’s icy shell and its surface interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.

Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission.

NASA Data Shows How Drought Changes Wildfire Recovery in the West

Wed, 03/27/2024 - 11:49am

NASA Data Shows How Drought Changes Wildfire Recovery in the West California’s 2017 Thomas Fire (shown) was included in a new analysis of more than 1,500 wildland fires teasing out how drought and fire combine to affect western U.S. lands.USDA Forest Service/ Stuart Palley

A new study using NASA satellite data reveals how drought affects the recovery of western ecosystems from fire, a result that could provide meaningful information for conservation efforts.

The West has been witnessing a trend of increasing number and intensity of wildland fires. Historically a natural part of the region’s ecology, fires have been exacerbated by climate change—including more frequent and intense droughts—and past efforts to suppress fires, which can lead to the accumulation of combustible material like fallen branches and leaves. But quantifying how fire and drought jointly affect ecosystems has proven difficult.

In the new study, researchers analyzed over 1,500 fires from 2014 to 2020 across the West, and also gathered data on drought conditions dating back to 1984. They found that droughts make it harder for grasslands and shrublands, such as those in Nevada and Utah, to recover after fires—even the less severe blazes. Forests, if not burned too badly, rebound better than grasslands and shrublands because some forest roots can tap into water deeper in the ground. The team reported its findings in the February 2024 issue of Nature Ecology & Environment.

“Many of the West’s grasslands experience low-severity fires,” said Shahryar Ahmad, lead author of the study and a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This study shows that even those blazes can trigger a slow recovery in these ecosystems if accompanied by a preceding drought.”

If ecosystems don’t have enough time to bounce back before another drought or fire, that could lead to permanent changes in the types of plants growing there. That, in turn, can increase the risk of soil erosion and landslides, and alter the usual patterns of water running off into streams and lakes.

“Once a fire is contained, that’s when the remediation efforts happen,” said Everett Hinkley, the national remote sensing program manager for the U.S. Forest Service, who wasn’t involved in the new research. “Understanding how a particular ecosystem and land cover type is going to respond after the fire informs what actions you need to take to restore the landscape.”

Without such restoration, changes in land cover can cascade to potentially affect agriculture, tourism, and other community livelihoods. To track the recovery of the different ecosystems, the researchers examined changes in evapotranspiration (ET)—the transfer of water to the atmosphere through evaporation from soil and open water and transpiration from plants—before and after the fires. Monitoring evapotranspiration helped the team identify whether different ecosystems, such as forests and grasslands, completely recovered after a fire, or if the recovery was delayed or disrupted.

That evapotranspiration data came from OpenET, a tool that calculates evapotranspiration at the scale of a quarter-acre across the western United States. It does so using models that harness publicly available data from the Landsat program, a partnership between NASA and the U.S. Geological Survey, along with other NASA and NOAA satellites.

“This study highlights the dominant control of drought on altering resilience of vegetation to fires in the West,” said Erin Urquhart, the water resources program manager at NASA Headquarters in Washington. “With ongoing climate change, it is imperative that land managers, policymakers, and communities work together, informed by such research, to adapt to these changes, mitigating risks and ensuring the sustainable use of water and other natural resources.”

The research also showed that forests, grasslands, and shrublands all struggle to recover from droughts that occur close in time with high-severity fires, which are becoming more common in the West. That can lead to potentially lasting changes not only in the plant communities but also in local and regional water dynamics.

Severe fires damage plants to such an extent that evapotranspiration is greatly reduced in the following years, the researchers found. So instead of evaporating into the atmosphere, more water sinks into the ground as recharge or becomes runoff.

Using a subset of nearly 800 fires from 2016 to 2018, the researchers calculated that across all the ecoregions in the study, an average of about 528 billion gallons (two cubic kilometers) of water was diverted as runoff or recharge during the first year after a fire. That’s equivalent to North Dakota’s annual water demand, or one quarter of Shasta Lake, California’s largest humanmade lake.

When more water becomes runoff, it means less could be available for ecosystem recovery or agriculture. As Earth’s climate continues to warm, understanding these shifts is crucial for developing strategies to manage water resources more effectively and ensure water security for future generations.

ESA, NASA Solar Observatory Discovers Its 5,000th Comet

ESA, NASA Solar Observatory Discovers Its 5,000th Comet

On March 25, 2024, a citizen scientist in the Czech Republic spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data. SOHO has achieved this milestone over 28 years in space, even though it was never designed to be a comet hunter.

The 5,000th comet discovered with the Solar and Heliospheric Observatory (SOHO) spacecraft is noted by a small white box in the upper left portion of this image. A zoomed-in inset shows the comet as a faint dot between the white vertical lines. The image was taken on March 25, 2024, by SOHO’s Large Angle and Spectrometric Coronagraph (LASCO), which uses a disk to block the bright Sun and reveal faint features around it.NASA/ESA/SOHO

The comet is a small body made of ice and rock that takes only a few years to orbit the Sun. It belongs to the “Marsden group” of comets. This group is thought to be related to comet 96P/Machholz (which SOHO observes when Machholz passes near the Sun every 5.3 years) and is named for the late scientist Brian Marsden who first recognized the group using SOHO observations. Only about 75 of the 5,000 comets discovered with SOHO belong to the Marsden group.

A joint mission of ESA (European Space Agency) and NASA, SOHO launched in December 1995 to study the Sun and the dynamics in its outer atmosphere, called the corona. A science instrument on SOHO, called the Large Angle and Spectrometric Coronagraph (LASCO), uses an artificial disk to block the blinding light of the Sun so scientists can study the corona and environment immediately around the Sun.

This also allows SOHO to do something many other spacecraft cannot – see comets flying close to the Sun, known as “sungrazing” comets or “sungrazers.” Many of these comets only brighten when they’re too close to the Sun for other observatories to see and would otherwise go undetected, lost in the bright glare of our star. While scientists expected SOHO to serendipitously find some comets during its mission, the spacecraft’s ability to spot them has made it the most prolific comet-finder in history – discovering more than half of the comets known today.

In fact, soon after SOHO launched, people around the world began spotting so many comets in its images that mission scientists needed a way to keep track of them all. In the early 2000s, they launched the NASA-funded Sungrazer Project that allows anyone to report comets they find in SOHO images.

SOHO’s 5,000th comet was found by Hanjie Tan, a Sungrazer Project participant who is originally from Guangzhou, China, and is currently pursuing a doctoral degree in astronomy in Prague, Czech Republic. Tan has been participating in the Sungrazer Project since he was 13 years old and is one of the project’s youngest comet discoverers.

“Since 2009, I’ve discovered over 200 comets,” Tan said. “I got into the Sungrazer Project because I love looking for comets. It’s really exciting to be the first to see comets get bright near the Sun after they’ve been traveling through space for thousands of years.”

Most of the 5,000 comets discovered using SOHO have been found with the help of an international cadre of volunteer comet hunters – many with no formal scientific training – participating in the Sungrazer Project.

“Prior to the launch of the SOHO mission and the Sungrazer Project, there were only a couple dozen sungrazing comets on record – that’s all we knew existed,” said Karl Battams, a space scientist at the U.S. Naval Research Lab in Washington, D.C., and the principal investigator for the Sungrazer Project. “The fact that we’ve finally reached this milestone – 5,000 comets – is just unbelievable to me.”

The vast number of comets discovered using SOHO has allowed scientists to learn more about sungrazing comets and groups of comets that orbit the Sun. Comets discovered by the Sungrazer Project have also helped scientists learn more about the Sun, by watching the comets plunge through our star’s atmosphere like small solar probes.

“The statistics of 5,000 comets, and looking at their orbits and trajectories through space, is a super unique dataset – it’s really valuable science,” Battams said. “It’s a testament to the countless hours the project participants have put into this. We absolutely would never had reached this milestone if it wasn’t for what the project volunteers have done.”

The Sungrazer Project is one of many opportunities that anyone can get involved with to help make discoveries with NASA during the Heliophysics Big Year, which extends through the end of 2024. Learn more about SOHO, the Sungrazer Project, and other NASA science projects you can participate in:
