Crew-9 will be the first human spaceflight mission to launch from Space Launch Complex-40 at Cape Canaveral Space Force Station. This is the ninth crew rotation mission with SpaceX to the orbiting laboratory under NASA’s Commercial Crew Program (CCP). The crew will spend approximately five months at the station, conducting more than 200 science and research demonstrations before returning in February 2025.

Once aboard the space station, Hague and Gorbunov will become members of the Expedition 72 crew and perform research, technology demonstrations, and maintenance activities. The pair will join NASA astronauts Don Petitt, Butch Wilmore, Suni Williams, as well as Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. Wilmore and Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.

The flag raising has been a tradition for missions supported at Marshall’s Huntsville Operations Support Center (HOSC), as well as a tradition within the CCP to celebrate the successful conclusion of NASA’s Agency Flight Readiness Review prior to launch. The HOSC provides engineering and mission operations support for the space station, the CCP, and Artemis missions, as well as science and technology demonstration missions. The Payload Operations Integration Center within HOSC operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day.

The CCP support team at Marshall provides crucial programmatic, engineering, and safety and mission assurance expertise for launch vehicles, spacecraft propulsion, and integrated vehicle performance. Marshall’s role within the CCP is to support certification that the spacecraft and launch vehicle are ready for launch. The support team performs engineering expertise, particularly for propulsion, as well as program management, safety and mission assurance, and spacecraft support.

The flag-raising ceremony was a joint effort between the Payload and Mission Operations Division (PMOD) and CCP team. Dave Gwaltney, technical assistant, specialty systems, and Commercial Crew Program representative, gave the introductions. He recognized Brady Doepke, structural analyst for liquid propulsion systems, for his significant contributions in preparation for Crew-9 mission success. Gwaltney said Doepke exemplified leadership and innovation through his guidance of Marshall’s CCP engineering team, which resulted in a successful risk assessment of the updated SpaceX turbine wheel fleet leader acceptance criteria.

Payload and Mission Operations Division Manager Nicole Pelfrey also recognized Thomas “Reid” Lawrence as the division’s Crew-9 honoree.

“Reid serves dutifully in the HOSC as part of the HOSC’s Data Operations Control Room Operations Engineers,” Pelfrey said. “Reid has a number of technical specialties, including his expertise in the Backup Control Center activation procedures. This expertise has been vital over the past year as JSC has worked through power upgrades. He also diligently ensures our ISS payload users receive their data and is a key engineer for the testing, verification, and operation of our HOSC interfaces that support commercial crew communications.”

Whitfield is an intern supporting the Marshall Office of Communications.

Take 5 with Shannon Segovia

By Wayne Smith

Talk with Shannon Segovia for any length of time and you’ll quickly discover the care and enthusiasm she has for her position as director of the Office of Communications at NASA’s Marshall Space Flight Center. And that care and enthusiasm extends to those she works with across the center to share news about Marshall missions and team members.

In her role, Segovia oversees a team responsible for media relations and public affairs, digital and social media, stakeholder relations and engagement, internal and employee communications, and executive communications for the center.

“We manage these activities for the entire center of about 7,000 people, so it is a definitely a very busy job!” said Segovia, a native of Athens, Alabama, who was named as permanent communications director this summer after more than 12 years at Marshall.

She was the deputy director of communications starting in June 2023 after working as Marshall’s news chief and public affairs team lead starting in 2019. From 2012 to 2019, Segovia was a public affairs officer at the center. Prior to joining NASA, she was the communications manager for the Tennessee Valley Authority’s Sequoyah Nuclear Plant near Chattanooga, Tennessee.

 At Marshall, she said it’s the people who continue to be her biggest motivators.

“As a public servant, I want the people I serve – the people who follow our channels, listen to the news stories we create, and attend our events – to know why NASA’s missions are important and critical to the world we live in,” Segovia said. “I am so fortunate to have such a brilliant team, and they motivate me daily with their hard work.”

“I’m also motivated by my husband and family because I want to make them proud. I want my nieces and nephews to have a bright future, and I truly believe the work we are doing at NASA will help them do that.”

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

Segovia: NASA’s missions depend on public and stakeholder support, and that is what our office does – ensures people know what we are doing at NASA and specifically at Marshall, why it is important, and how our missions are benefiting humanity. From social media posts to events like the South Star music festival to interviews with media outlets and stakeholder tours, we use every channel we can to tell others about the work we are doing at Marshall and NASA. Our office touches every organization at the center, and it is so exciting to have a front seat to everything we are doing to get humans back to the Moon and on to Mars.

Question: What has been the proudest moment of your career and why?

Segovia: I helped take a team of 12 Marshall female engineers to The Today Show in 2019 for a segment about International Women’s Day. As a public affairs specialist, one of our job duties is to prepare subject matter experts for interviews, making sure they have messages, talking points, and anything else they need. I have never been more proud to be a woman and to work for Marshall than I was that day, seeing how well these women represented NASA and the extraordinary achievements they have made possible. It also made me even more thankful for the job I have – preparing them to make sure they felt confident and could talk about their work was a wonderful experience. The other moment in my career I will never forget is the Artemis I launch in November 2022. I’ve supported the Space Launch System since I started working at NASA, and seeing that rocket fly was one of the best moments of my career. It was the culmination of so much hard work and sacrifice from so many people and was truly an overwhelming and amazing experience.

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

Segovia: My parents have always been my No. 1 fans, encouragers, and supporters. They instilled in me a strong work ethic and the belief I could do anything I wanted to do if I worked hard. They made education a priority for my brothers and I and would do anything to help us succeed. I am so fortunate to have such a wonderful family. My mom always wanted me to do something in the medical field, but a biology course in college changed my mind quickly on that. I wasn’t sure what I wanted to do but had been at school for two years and needed to declare a major. I liked to write and read but didn’t know how to make a career out of that until I went to a journalism class taught by Ms. Bobbie Hurt at the University of North Alabama, and I was hooked. She became my mentor and really taught me how to be a good writer, which has been the foundation for my entire career. I ended up with a double major in journalism and public relations, and it was one of the best decisions I ever made.

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

Segovia: Find people to whom you can go to for advice, who have your back, and can help you accomplish your goals. I’ve had some amazing mentors, teammates, and bosses who have not only supported me but pushed me to do things I wasn’t sure I could do and helped me even when I messed up. I would not be here without them, and I think it is so important to have those people in your entire career, but especially when you are new. Ask for help when you need it. Time flies, so enjoy the season and job you are in. You will know when it is time to move on, but being present and learning from where you are will help you succeed.

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

Segovia: I love the water – ocean, river, pool, lake – I like being outside and water activities. I love to read and travel, and also to spend time with family and friends. I have three nieces and two nephews, and I like to go to their games and activities. I have a 4-year-old terrier mix named Ted and I enjoy taking him on walks and to the park.

NASA Awards $1.5 Million at Watts on the Moon Challenge Finale

NASA has awarded a total of $1.5 million to two U.S. teams for their novel technology solutions addressing energy distribution, management, and storage as part of the agency’s Watts on the Moon Challenge. The innovations from this challenge aim to support NASA’s Artemis missions, which will establish long-term human presence on the Moon.

Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from The University of California, Santa Barbara won the $1 million grand prize in NASA’s Watts on the Moon Challenge. Their team developed a low-mass, high efficiency cable and featured energy storage batteries on both ends of their power transmission and energy storage system. NASA/GRC/Sara Lowthian-Hanna

This two-phase competition has challenged U.S. innovators to develop breakthrough power transmission and energy storage technologies that could enable long-duration Moon missions to advance the nation’s lunar exploration goals. The final phase of the challenge concluded with a technology showcase and winners’ announcement ceremony Sept. 20 at Great Lakes Science Center in Cleveland, Ohio, home of the visitor center for NASA’s Glenn Research Center.

“Congratulations to the finalist teams for developing impactful power solutions in support of NASA’s goal to sustain human presence on the Moon,” said Kim Krome-Sieja, acting program manager for Centennial Challenges at NASA’s Marshall Space Flight Center. “These technologies seek to improve our ability to explore and make discoveries in space and could have implications for improving power systems on Earth.”

The winning teams are:

  • First prize ($1 million): H.E.L.P.S. (High Efficiency Long-Range Power Solution) of Santa Barbara, California
  • Second prize ($500,000): Orbital Mining Corporation of Golden, Colorado

Four teams were invited to refine their hardware and deliver full system prototypes in the final stage of the competition, and three finalist teams completed their technology solutions for demonstration and assessment at Glenn. The technologies were the first power transmission and energy storage prototypes to be tested by NASA in a vacuum chamber mimicking the freezing temperature and absence of pressure found at the permanently shadowed regions of the Lunar South Pole. The simulation required the teams’ power systems to demonstrate operability over six hours of solar daylight and 18 hours of darkness with the user three kilometers (nearly two miles) away from the power source.

During this competition stage, judges scored the finalists’ solutions based on a Total Effective System Mass (TESM) calculation, which measures the effectiveness of the system relative to its size and weight – or mass – and the total energy provided by the power source. The highest-performing solution was identified based on having the lowest TESM value – imitating the challenges that space missions face when attempting to reduce mass while meeting the mission’s electrical power needs.

His team’s power transmission and energy storage technology took home the second-place prize in the four-year, $5 million challenge, winning a cash prize of $500,000. NASA/Sara Hanna-Lowthian

Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from University of California, Santa Barbara, won the grand prize for their hardware solution, which had the lowest mass and highest efficiency of all competitors. The technology also featured a special cable operating at 800 volts and an innovative use of energy storage batteries on both ends of the transmission system. They also employed a variable radiation shield to switch between conserving heat during cold periods and disposing of excess heat during high power modes. The final 48-hour test proved their system design effectively met the power transmission, energy storage, and thermal challenges in the final phase of competition.

Orbital Mining Corporation, a space technology startup, received the second prize for its hardware solution that also successfully completed the 48-hour test with high performance. They employed a high-voltage converter system coupled with a low-mass cable and a lithium-ion battery.

“The energy solutions developed by the challenge teams are poised to address NASA’s space technology priorities,” said Amy Kaminski, program executive for Prizes, Challenges, and Crowdsourcing in NASA’s Space Technology Mission Directorate at NASA Headquarters. “These solutions support NASA’s recently ranked civil space shortfalls, including in the top category of surviving and operating through the lunar night.”

Watch the finale of NASA’s Watts on the Moon challenge, a $5 million, two-phase competition designed to develop breakthrough power transmission and energy storage technologies.

During the technology showcase and winners’ announcement ceremony, NASA experts, media, and members of the public gathered to see the finalist teams’ technologies and hear perspectives from the teams’ participation in the challenge. After the winners were announced, event attendees were also welcome to meet NASA astronaut Stephen Bowen.

The Watts on the Moon Challenge is a NASA Centennial Challenge led by Glenn. Marshall manages Centennial Challenges, which are part of the agency’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate. NASA contracted HeroX to support the administration of this challenge.

Michoud Continues Work on Evolved Stage of SLS Rocket for Future Artemis Missions

Manufacturing equipment that will be used to build components for NASA’s SLS (Space Launch System) rocket for future Artemis missions is being installed at the agency’s Michoud Assembly Facility.

The novel tooling will be used to produce the SLS rocket’s advanced exploration upper stage, or EUS, in the factory’s new manufacturing area. The EUS will serve as the upper, or in-space, stage for all Block 1B and Block 2 SLS flights in both crew and cargo configurations.

In tandem, NASA and Boeing, the SLS lead contractor for the core stage and exploration upper stage, are producing structural test articles and flight hardware structures for the upper stage at Michoud and the agency’s Marshall Space Flight Center. Early manufacturing is already underway at Michoud while preparations for an engine-firing test series for the upper stage are in progress at nearby Stennis Space Center.

“The newly modified manufacturing space for the exploration upper stage signifies the start of production for the next evolution of SLS Moon rockets at Michoud,” said Hansel Gill, director at Michoud. “With Orion spacecraft manufacturing and SLS core stage assembly in flow at Michoud for the past several years, standing up a new production line and enhanced capability at Michoud for EUS is a significant achievement and a reason for anticipation and enthusiasm for Michoud and the SLS Program.”

The advanced upper stage for SLS is planned to make its first flight with Artemis IV and replaces the single-engine Interim Cryogenic Propulsion Stage (ICPS) that serves as the in-space stage on the initial SLS Block 1 configuration of the rocket. With its larger liquid hydrogen and liquid oxygen propellant tanks feeding four L3 Harris Technologies- built RL10C-3 engines, the EUS generates nearly four times the thrust of the ICPS, providing unrivaled lift capability to the SLS Block 1B and Block 2 rockets and making a new generation of crewed lunar missions possible.

This upgraded and more powerful rocket will increase the SLS rocket’s payload to the Moon by 40%, from 27 metric tons (59,525 lbs.) with Block 1 to 38 metric tons (83,776 lbs.) in the crew configuration. Launching crewed missions along with other large payloads enables multiple large-scale objectives to be accomplished in a single mission.

Through the Artemis campaign, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon. The rocket is part of NASA’s deep space exploration plans, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, Gateway in orbit around the Moon, and commercial human landing systems. NASA’s SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

I am Artemis: Chris Pereira

Chris Pereira can personally attest to the immense gravitational attraction of black holes. He’s been in love with space ever since he saw a video on the topic in a high school science class.

But it wasn’t just any science class. It was one specially designed for English learners.

As RS-25’s operations integrator, Chris Pereira is responsible for ensuring that the many pieces of the program – from tracking on-time procurement of supplies and labor loads to coordinating priorities on various in-demand machine centers – come together to deliver a quality product.Mike Labbe, L3Harris Technologies

“I was born and raised in Guatemala,” Pereira said. “I came here at 14 unable to speak any English.”

Pereira did not know how to navigate the U.S. educational system either, but after that class, he was certain he wanted a career in space.

Thus began a journey that ultimately landed him at L3Harris Technologies, where he works in the Aerojet Rocketdyne segment as an engineer and operations integrator on the RS-25 engine – used to power the core stage of NASA’s SLS (Space Launch System) rocket that will launch astronauts to the Moon under NASA’s Artemis campaign.

Pereira’s first step was to stay after class and ask to borrow a copy of the video on black holes. His teacher not only obliged but took him across the street to the local library to get his first library card.

Pereira quickly recognized that the pathway to his desired career in space was through higher education. It was equally clear, however, that he was not yet on that pathway. English as a Second Language classes, including that science class, did not count toward college admissions. His guidance counselor, meanwhile, was nudging him toward the trades.

But with the help of teachers and a new guidance counselor, he got himself on the college-bound track.

“I came to understand there were multiple career pathways to explore my interest in space,” Pereira said. “One was engineering.”

There was a lot of catching up to do, so Pereira took eight classes per day, including honors courses. He also worked every day after school cleaning a gymnasium from 6 to 11 p.m. to help his family make ends meet.

Pereira earned his mechanical engineering degree at California State University at Los Angeles while also working as a senior educator at the California Science Center to cover the cost of his college tuition and living expenses.

Pereira’s first career experience was as an intern in manufacturing engineering at Aerojet Rocketdyne. “I learned that making 100% mission-success engines requires a strong culture of attention to detail, teamwork and solid work ethics.” Pereira said. His first full-fledged engineering job was with Honeywell Aerospace working on aircraft programs.

Eventually, space came calling – literally. “My mentor at Aerojet Rocketdyne called me up and said, ‘Chris, I have a job for you,’” Pereira said.

He began his new job working on rocket engine programs including the AR1 and RS-68 but shifted to the RS-25 after NASA awarded Aerojet Rocketdyne a contract for newly manufactured versions of the engine. Initial versions of the SLS are using refurbished engines from the Space Shuttle Program. Evolved versions of the RS-25 recently concluded a critical test series and will debut with the fifth Artemis flight.

As RS-25’s operations integrator, Pereira is responsible for ensuring that the many pieces of the program – from tracking on-time procurement of supplies and labor loads to coordinating priorities on various in-demand machine centers – come together to deliver a quality product.

Playing a key role in the nation’s effort to return astronauts to the Moon feels a bit like coming home again, Pereira said. “You develop your first love, work really hard, take different pathways and encounter new passions,” he said. “It’s almost funny how the world and life work out – it’s like I’ve taken a big circle back to my first love.”

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, supporting ground systems, 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.

‘Legacy of the Invisible’ Event Celebrates Mural, Marshall’s Astrophysics Missions

Renee Weber, chief scientist at NASA’s Marshall Space Flight Center, talks during the “Legacy of the Invisible” event in downtown Huntsville on Sept. 20. About 300 people attended the event, which coincided with the 25th anniversary of the launch of the Chandra X-ray Observatory. The celebration featured “No Straight Lines,” a new mural at the corner of Clinton Avenue and Washington Street by local artist Float. The mural honors Huntsville’s rich scientific legacy in astrophysics and highlights the groundbreaking discoveries made possible by Marshall scientists and engineers. Other speakers included Collen Wilson-Hodge, principal investigator of the Fermi Gamma-ray Space Telescope. The event also offered members of the community the opportunity to meet the scientists who worked on some of NASA’s most revolutionary astrophysics missions. Featured exhibits from Marshall included the Apollo Telescope mount, the main science instrument on Skylab; the High Energy Astrophysics Program (HEAO); the BATSE instrument on the Compton Gamma-ray Observatory; Chandra X-ray Observatory; Fermi; IXPE (Imaging X-ray Polarimetry Explorer); and Marshall’s X-Ray and Cryogenic Facility. “I had a really nice time at the event,” Weber said. “It’s always great to see such interest and enthusiasm in our science work from the public.” Wilson-Hodge said the mural is an artistic depiction of the historic event detected with the Fermi Gamma-ray Burst Monitor and the Laser Interferometer Gravitational-wave Observatory on Aug. 17, 2017. “On that day, for the first time ever, we observed both a gamma-ray burst and gravitational waves from two very dense neutron stars merging to form a black hole,” she said.

Chandra Finds Galaxy Cluster that Crosses the Streams

Astronomers using NASA’s Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure.

Researchers have discovered an enormous, comet-like tail of hot gas – spanning over 1.6 million light-years long – trailing behind a galaxy within the galaxy cluster called Zwicky 8338, or Z8338.X-ray: NASA/CXC/Xiamen Univ./C. Ge; Optical: DESI collaboration; Image Processing: NASA/CXC/SAO/N. Wolk

Researchers have discovered an enormous, comet-like tail of hot gas – spanning over 1.6 million light-years long – trailing behind a galaxy within the galaxy cluster called Zwicky 8338 (Z8338 for short). This tail, spawned as the galaxy had some of its gas stripped off by the hot gas it is hurtling through, has split into two streams.

This is the second pair of tails trailing behind a galaxy in this system. Previously, astronomers discovered a shorter pair of tails from a different galaxy near this latest one. This newer and longer set of tails was only seen because of a deeper observation with Chandra that revealed the fainter X-rays.

Astronomers now have evidence that these streams trailing behind the speeding galaxies have crossed one another. Z8338 is a chaotic landscape of galaxies, superheated gas, and shock waves (akin to sonic booms created by supersonic jets) in one relatively small region of space. These galaxies are in motion because they were part of two galaxy clusters that collided with each other to create Z8338.

This new composite image shows this spectacle. X-rays from Chandra (represented in purple) outline the multimillion-degree gas that outweighs all of the galaxies in the cluster. The Chandra data also shows where this gas has been jettisoned behind the moving galaxies. Meanwhile an optical image from the Dark Energy Survey from the Cerro Tololo Inter-American Observatory in Chile shows the individual galaxies peppered throughout the same field of view.

The original gas tail discovered in Z8338 is about 800,000 light-years long and is seen as vertical in this image. The researchers think the gas in this tail is being stripped away from a large galaxy as it travels through the galaxy cluster. The head of the tail is a cloud of relatively cool gas about 100,000 light-years away from the galaxy it was stripped from. This tail is also separated into two parts.

A labeled version of the galaxy cluster Zwicky 8338.X-ray: NASA/CXC/Xiamen Univ./C. Ge; Optical: DESI collaboration; Image Processing: NASA/CXC/SAO/N. Wolk

The team proposes that the detachment of the tail from the large galaxy may have been caused by the passage of the other, longer tail. Under this scenario, the tail detached from the galaxy because of the crossing of the streams.

The results give useful information about the detachment and destruction of clouds of cooler gas like those seen in the head of the detached tail. This work shows that the cloud can survive for at least 30 million years after it is detached. During that time, a new generation of stars and planets may form within it.

The Z8338 galaxy cluster and its jumble of galactic streams are located about 670 million light-years from Earth. A paper describing these results appeared in the Aug. 8, 2023, issue of the Monthly Notices of the Royal Astronomical Society and is available here.

New Video Series Spotlights Engineers on NASA’s Europa Clipper Mission

What does it take to build a massive spacecraft that will seek to determine if a mysterious moon has the right ingredients for life? Find out in a new video series called “Behind the Spacecraft,” which offers behind-the-scenes glimpses into the roles of five engineers working on NASA’s Europa Clipper mission, from building the spacecraft’s communications systems to putting it through rigorous tests so the orbiter can meet its science goals in space.

With its launch period opening Oct. 10, Europa Clipper is the agency’s first mission dedicated to exploring an ocean world beyond Earth. The spacecraft will travel 1.8 billion miles to the Jupiter system, where it will investigate the gas giant’s moon Europa, which scientists believe contains a global saltwater ocean beneath its icy shell.

The videos are being released here weekly. The first two are already out.

Meet the team:

  • Dipak Srinivasan, lead communications systems engineer at the Johns Hopkins Applied Physics Laboratory, makes sure the Europa Clipper team can communicate with the spacecraft. Learn more about his work in the video above.
  • Sarah Elizabeth McCandless, navigation engineer at NASA’s Jet Propulsion Laboratory, helped plan Europa Clipper’s trajectory, ensuring the spacecraft arrives at Jupiter safely and has a path to fly by Europa dozens of times. Learn more about Sarah’s work here.
  • Jenny Kampmeier, a science systems engineer at JPL, acts as an interface between mission scientists and engineers.
  • Andres Rivera, a systems engineer at JPL and first-generation American, works on Europa Clipper’s cruise phase — the journey from Earth to Jupiter.
  • Valeria Salazar, an integration and test engineer at JPL who spent her childhood in Mexico, helped test the Europa Clipper spacecraft to ensure its launch readiness.

Europa Clipper experts will answer questions about the mission in a NASA Science Live show airing in English on Oct. 1, and in Spanish on Oct. 3. The broadcasts will appear on NASA+, YouTubeFacebook, and X. The Spanish broadcast will be streamed on the NASA en Español YouTube channel. Viewers can submit questions on social media using the hashtag #askNASA or by leaving a comment in the chat section of the Facebook or YouTube stream.

Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission and will fly through the most punishing radiation environment of any planet in the solar system. The spacecraft will orbit Jupiter and, during multiple flybys of Europa, will collect a wealth of scientific data with nine science instruments and an experiment that uses its telecommunications system to gather gravity data.

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. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft.

Space Travel Weakens the Heart, New Study Finds

Universe Today - Wed, 09/25/2024 - 2:37pm

It’s no secret that spending extended periods in space takes a toll on the human body. For years, NASA and other space agencies have been researching the effects of microgravity on humans, animals, and plants aboard the International Space Station (ISS). So far, the research has shown that being in space for long periods leads to muscle atrophy, bone density loss, changes in vision, gene expression, and psychological issues. Knowing these effects and how to mitigate them is essential given our future space exploration goals, which include long-duration missions to the Moon, Mars, and beyond.

However, according to a recent experiment led by researchers at Johns Hopkins University and supported by NASA’s Johnson Space Center, it appears that heart tissues “really don’t fare well in space” either. The experiment consisted of 48 samples of human bioengineered heart tissue being sent to the ISS for 30 days. As they indicate in their paper, the experiment demonstrates that exposure to microgravity weakens heart tissue and weakens its ability to maintain rhythmic beats. These results indicate that additional measures must be taken to ensure humans can maintain their cardiovascular health in space.

The study was led by Deok-Ho Kim and his colleagues from the Department of Biomedical Engineering at Johns Hopkins University (BME-JHU) and the JHU Center for Microphysiological Systems. They were joined by researchers from UC Boulder’s Ann and HJ Smead Department of Aerospace Engineering Sciences, the Institute for Stem Cell & Regenerative Medicine (ISCRM) and the Center for Cardiovascular Biology at the University of Washington, the Stanford Institute for Stem Cell & Regenerative Medicine, BioServe Space Technologies, and NASA’s Johnson Space Center. The paper that details their findings was published yesterday (September 23rd) in the Proceedings of the National Academy of Sciences.

Previous research has shown that astronauts returning to Earth from the ISS suffer from a myriad of health effects consistent with certain age-related conditions, including reduced heart muscle function and irregular heartbeats (arrhythmias), most of which will dissipate over time. However, none of this research has addressed what happens at the cellular and molecular level. To learn more about these effects and how to mitigate them, Kim and his colleagues sent an automated “heart-on-a-chip” platform to the ISS for study.

To create this payload, the team relied on human-induced pluripotent stem cells (iPSCs), which can become many types of cells, to produce cardiomyocytes (heart muscle cells). These resulting tissues were placed in a miniaturized bioengineered tissue chip designed to mimic the environment of an adult human heart. The chips would then collect data on how the tissues would rhythmically contract, imitating how the heart beats. One set of biochips was launched aboard the SpaceX CRS-20 mission to the ISS in March 2020, while another was kept on Earth as a control group.

Once on the ISS, astronaut Jessica Meir tended the experiment, changing the liquid nutrients surrounding the tissues once each week while preserving tissue samples at specific intervals so gene readout and imaging analyses could be conducted upon their return to Earth. Meanwhile, the experiment sent real-time data back to Earth every 30 minutes (for 10 seconds at a time) on the tissue samples’ contractions and any irregular beating patterns (arrhythmias).

“An incredible amount of cutting-edge technology in the areas of stem cell and tissue engineering, biosensors and bioelectronics, and microfabrication went into ensuring the viability of these tissues in space,” said Kim in a recent Hub news release.

When the tissue chambers returned to Earth, he and his colleagues continued to maintain and collect data from the samples to see if there was any change in their abilities to contract. In addition to losing strength, the muscle tissues developed arrhythmias, consistent with age-related heart conditions. In a healthy human heart, the time between beats is about a second, whereas the tissue samples lasted nearly five times as long – though they returned to nearly normal once returned to Earth.

The team further found that the tissue cell’s protein bundles that help them contract (sarcomeres) were shorter and more disordered than those of the control group, another symptom of heart disease. What’s more, the mitochondria in the tissue samples grew larger and rounder and lost the characteristic folds that help them produce and use energy. Lastly, the gene readout in the tissues showed increased gene production related to inflammation and an imbalance of free radicals and antioxidants (oxidative stress).

This is not only consistent with age-related heart disease but also consistently demonstrated in astronauts’ post-flight checks. The team says these findings expand our scientific knowledge of microgravity’s potential effects on human health in space and could also advance the study of heart muscle aging and therapeutics on Earth. In 2023, Kim’s lab followed up on this experiment by sending a second batch of tissue samples to the ISS to test drugs that could help protect heart muscles from the effects of microgravity and help people maintain heart function as they age.

Meanwhile, the team continues to improve its tissue-on-a-chip system and has teamed up with NASA’s Space Radiation Laboratory to study the effects of space radiation on heart muscles. These tests will assess the threat solar and cosmic rays pose to cardiovascular health beyond Low Earth Orbit (LEO), where Earth’s magnetic field protects against most space radiation.

NASA’s Art Program is Back

NASA - Breaking News - Wed, 09/25/2024 - 2:20pm
NASA/Joel Kowsky

NASA launched its reimagined art program by unveiling two murals on Sept. 23, 2024. The murals, titled “To the Moon, and Back,” were created by New York-based artist team Geraluz and WERC and use geometrical patterns to invite deeper reflection on the exploration, creativity, and connection with the cosmos. The vision of this next phase is to inspire and engage the Artemis Generation with community murals and other art projects for the benefit of humanity.

NASA has long used art to tell the story of its awe-inspiring missions. Soon after its inception, the agency started a formal program commissioning artists to develop inspiring pieces like portraits and paintings that highlighted an unexpected side of the agency. In 1962, NASA’s then Administrator James Webb tasked staffer and artist James Dean with implementing the new program, and with the help of the National Gallery of Art, Dean laid the framework to artistically capture the inspiration of NASA’s Apollo program. As the NASA Art Program continues to evolve, the agency remains focused on inspiring and engaging the next generation of explorers – the Artemis Generation – in new and unexpected ways, including through art.
