‘Be King’: Team Redstone Invites All to Honor Civil Rights Icon’s Legacy

By Jessica Barnett

Several accomplished speakers took to the stage Jan. 11 at NASA’s Marshall Space Flight Center to share how Martin Luther King Jr.’s life and legacy helped shape their lives.

The event was hosted by Marshall’s ODEO (Office of Diversity and Equal Opportunity), along with the FBI and U.S. Army, in the center’s Activities Building 4316 as a way of honoring King, a minister and activist from Atlanta who rose to national prominence as a key figure in the civil rights movement of the 1950s and 1960s. King would have been 95 on Jan. 15.

National Mentor Month: Navigating Mentorship with Michoud’s Cynthia Spraul and Marie Allain

By Celine Smith

As a mentor at NASA’s MAF (Michoud Assembly Facility), Cynthia Spraul says her goal is the success of her mentee, Marie Allain.

“It feels really good to pass on my experience to somebody who can get there faster and go beyond,” Spraul said.

For some, a mentorship may seem daunting. A mentee looking for a mentor in a new environment can find it difficult to find someone they trust to guide their career and personal growth. Meanwhile, mentors may feel discouraged, thinking they might not have enough knowledge to be in their role.

Hoping their experience can help others during National Mentor Month, Spraul and Allain shared their insight about finding and starting a mentorship.

Spraul worked for Lockheed Martin at Michoud on the Space Shuttle Program’s External Tank for 20 years. For the past 17 years, she has worked for NASA at Michoud, where she is currently the integrations lead.

“I work on strategic site management, resource management, and contract management,” Spraul said.

Allain graduated with a bachelor’s degree in mechanical engineering from LSU (Louisiana State University) in 2021. “I got involved with the American Institute of Aeronautics and Astronautics at LSU, an aerospace professional society, which is how I really got into aerospace,” she said.

Allain now works as a project coordinator on Spraul’s integrations team. She performs project management in the Michoud Directorate and contract administration along with Component Processing Facility management.

Spraul was asked to coordinate the summer internship program at Michoud, which is how she got started as a mentor. Spraul was the program’s first mentor at MAF. So, when Allain approached her requesting mentorship, she gladly took her on.

Question: What does mentorship mean to you?

Spraul: Seeing someone’s interest in what you do, like Marie taking an interest in my past experience, reinvigorates my love for my job and my desire to work. Mentoring makes work fun for me again. I might be doing the same things, but since I’m teaching somebody while I’m doing it, I get to listen to myself when I talk. It makes me go, ‘Oh, wow, I really get to do this.’ I get excited about my work all over again.

Allain: My mentor makes me feel like I’m starting my career with the insight a person at the peak of their career wishes they had when they started. This mentorship gives me an opportunity to start on the right foot. I get to start out with tools that will help me later down the line. It gives me the opportunity to glean a lot of insight from people who have been at Michoud for a long time. They know the history of the place firsthand. A lot of people in this office are getting near retirement, and before too long, we’re going to have a lot of information, a lot of our history, that’s lost. I get the opportunity to retain some of that history from somebody who experienced it firsthand.

Question: What impact has mentorship had on you and your career?

Spraul: Someone having an interest in what I’m doing is a catalyst for me and my own career growth. The more I get reinterested in what I’m doing, the more I ask myself, ‘What’s my next step and how do I get there?’ Especially because Allain’s watching me. It’s always better to perform when someone’s watching you. There’s a reason to do better and grow because young people are watching. I also tend to turn my focus on the coming generations, because they’re going to be here when I’m gone.

Allain: Before going into this mentorship, I struggled visualizing what my career could look like. Especially coming right out of college, nobody knows what jobs actually exist. Spraul knows what our organization is and what exists in it, and what it’s like to work in different roles in the organization. The kind of insight she provided completely changed how I feel about my career. I have an actual vision of where I’m headed. Beforehand, I felt I was somewhat free floating in space.

Question: How did you find and connect with your mentor/mentee?

Spraul: After mentoring college interns over the years, I’m always excited when I learn something new from them. When Marie came to me requesting mentorship, she had already taught me so many things that I thought it was a great idea to expand our dialogue.

Allain: It was natural for us.After the first few months of working together on projects, we would have lunch together. We’d spend some time together and talk. I started to realize she and I have a lot in common.

Question: What steps did you take to approach your mentor/mentee to initiate the partnership?

Allain: I started asking her for insight about her experience and her career. The mentorship relationship developed from there. It started with discussions during lunch and developed into conversations about everything from work stories to life experience.

Spraul: Allain asked introspective questions that would lead us on a good tangent while we worked together as well. We also started staying after work so I could have longer conversations with Allain about a path for her future.

Question: What advice do you have for someone else considering finding or being a mentor?

Allain: For mentees, find somebody you look up to in your organization and just ask. Most potential mentors see it as a huge compliment. The worst thing that can happen is being told no. I think most people at NASA would say yes. Don’t feel like you’re putting somebody out by asking them to mentor you. Also, don’t sit around assuming mentors are going to come to you.

Spraul: I would suggest that mentees observe other people above them. Mentees should watch how potential mentors conduct themselves to see who they would like to model themselves after. For mentors, a lot of work goes into being mentor. It’s more than showing up. Be prepared by knowing what you’re going to have your mentee do and try. Being a mentor does take some work, but you receive tenfold in your own career and the enjoyment of your day. Don’t be afraid is my best advice. Even showing up is valuable to the mentee. You’ll get results from anything else you put into it.

Editor’s note: This is the first in a Marshall Star series during National Mentor Month in January. Marshall team members can learn more about the benefits of mentoring on Inside Marshall.

NASA Shares Progress Toward Early Artemis Moon Missions with Crew

NASA announced Jan. 9 updates to its Artemis campaign that will establish the foundation for long-term scientific exploration at the Moon, land the first woman and first person of color on the lunar surface, and prepare for human expeditions to Mars for the benefit of all. To safely carry out these missions, agency leaders are adjusting the schedules for Artemis II and Artemis III to allow teams to work through challenges associated with first-time developments, operations, and integration.

NASA will now target September 2025 for Artemis II, the first crewed Artemis mission around the Moon, and September 2026 for Artemis III, which is planned to land the first astronauts near the lunar South Pole. Artemis IV, the first mission to the Gateway lunar space station, remains on track for 2028.

NASA

“We are returning to the Moon in a way we never have before, and the safety of our astronauts is NASA’s top priority as we prepare for future Artemis missions,” said NASA Administrator Bill Nelson. “We’ve learned a lot since Artemis I, and the success of these early missions relies on our commercial and international partnerships to further our reach and understanding of humanity’s place in our solar system. Artemis represents what we can accomplish as a nation – and as a global coalition. When we set our sights on what is hard, together, we can achieve what is great.”

Ensuring crew safety is the primary driver for the Artemis II schedule changes. As the first Artemis flight test with crew aboard the Orion spacecraft, the mission will test critical environmental control and life support systems required to support astronauts. NASA’s testing to qualify components to keep the crew safe and ensure mission success has uncovered issues that require additional time to resolve. Teams are troubleshooting a battery issue and addressing challenges with a circuitry component responsible for air ventilation and temperature control.

NASA’s investigation into unexpected loss of char layer pieces from the spacecraft’s heat shield during Artemis I is expected to conclude this spring. Teams have taken a methodical approach to understand the issue, including extensive sampling of the heat shield, testing, and review of data from sensors and imagery.

The new timeline for Artemis III aligns with the updated schedule for Artemis II, ensures the agency can incorporate lessons learned from Artemis II into the next mission, and acknowledges development challenges experienced by NASA’s industry partners. As each crewed Artemis mission increases complexity and adds flight tests for new systems, the adjusted schedule will give the providers developing new capabilities – SpaceX for the HLS (human landing system) and Axiom Space for the next-generation spacesuits – additional time for testing and any refinements ahead of the mission.

“We are letting the hardware talk to us so that crew safety drives our decision-making. We will use the Artemis II flight test, and each flight that follows, to reduce risk for future Moon missions,” said Catherine Koerner, associate administrator, Exploration Systems Development Mission Directorate at NASA Headquarters. “We are resolving challenges associated with first-time capabilities and operations, and we are closer than ever to establishing sustained exploration of Earth’s nearest neighbor under Artemis.”

In addition to the schedule updates for Artemis II and III, NASA is reviewing the schedule for launching the first integrated elements of Gateway, previously planned for October 2025, to provide additional development time and better align that launch with the Artemis IV mission in 2028.

NASA also shared that it has asked both Artemis human landing system providers – SpaceX and Blue Origin – to begin applying knowledge gained in developing their systems as part of their existing contracts toward future variations to potentially deliver large cargo on later missions.

“Artemis is a long-term exploration campaign to conduct science at the Moon with astronauts and prepare for future human missions to Mars. That means we must get it right as we develop and fly our foundational systems so that we can safely carry out these missions,” said Amit Kshatriya, deputy associate administrator of Exploration Systems Development, and manager of NASA’s Moon to Mars Program Office at headquarters. “Crew safety is and will remain our number one priority.”

NASA leaders emphasized the importance of all partners delivering on time so the agency can maximize the flight objectives with available hardware on a given mission. NASA regularly assesses progress and timelines and as a part of integrated programmatic planning to ensure the agency and its partners can successfully accomplish its Moon to Mars exploration goals.

With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

NASA’s Marshall Space Flight Center manages the SLS and HLS programs. NASA’s Michoud Assembly Facility, which is managed by Marshall, manufactures several Artemis components, including the SLS core stage.

IXPE Helps Researchers Maximize ‘Microquasar’ Findings

By Rick Smith

The powerful gravity fields of black holes can devour whole planets’ worth of matter – often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand that these high-speed jets can accelerate these particles, called cosmic rays, but little is definitively known about that process.

Recent findings by researchers using data from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) spacecraft give scientists new clues as to how particle acceleration happens in this extreme environment. The observations came from a “microquasar,” a system comprised of a black hole siphoning off material from a companion star.

The microquasar in question – Stephenson and Sanduleak 433, or SS 433 – sits in the center of the supernova remnant W50 in the constellation Aquila, some 18,000 light-years from Earth. SS 433’s powerful jets, which distort the remnant’s shape and earned it the nickname the “Manatee Nebula,” have been clocked at roughly 26% of the speed of light, or more than 48,000 miles per second. Identified in the late 1970s, SS 433 is the first microquasar ever discovered.

IXPE’s three onboard telescopes measure a special property of X-ray light called polarization, which tells scientists about the organization and alignment of electromagnetic waves at X-ray frequencies. X-ray polarization helps researchers understand the physical processes taking place within extreme regions of our universe – such as the environment around black holes – and how particles get accelerated in these regions.

IXPE spent 18 days in April and May of 2023 studying one such acceleration site in the eastern lobe of SS 433, where emissions are made by energetic electrons spiraling in a magnetic field – a process called synchrotron radiation.

“The IXPE data show that the magnetic field near the acceleration region points in the direction the jets are moving,” said astrophysicist Philip Kaaret of NASA’s Marshall Space Flight Center, and principal investigator of the IXPE mission, along with lead author of a new paper about the findings at SS 433.

“The high level of polarization seen with IXPE shows that the magnetic field is well ordered, with at least half of the field aligned in the same direction,” Kaaret said.

That finding was unexpected, he said. Researchers have long theorized that the interaction between the jet and the interstellar medium – the environment of gas and dust between stars – likely creates a shock, leading to disordered magnetic fields.

The data suggests a new possibility, Kaaret said – that the magnetic fields within the powerful jets may be “trapped” and stretched when they collide with interstellar matter, directly impacting their alignment in the region of particle acceleration.

Since the 1980s, researchers have surmised that SS 433’s jets act as particle accelerators. In 2018, observers at the High-Altitude Water Cherenkov Observatory in Puebla, Mexico, verified the jets’ acceleration effect, and scientists used NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) and the European Space Agency’s XMM-Newton observatories to pinpoint the region of acceleration.

As researchers continue to assess IXPE findings and study new targets in space, its data also could help determine whether the same mechanism acts to align magnetic fields in outflows expelled by a variety of phenomena – from black hole jets streaming away from supernova remnants to debris ejected from exploded stars such as blazars.

“This very delicate measurement was made possible by the imaging capabilities of IXPE’s X-ray polarimeters, making possible the detection of the tenuous signal in a small region of the jet 95 light-years from the central black hole,” said Paolo Soffitta, Italian principal investigator for the IXPE mission.

The new paper, detailing IXPE’s observations at SS 433, is available in the latest edition of The Astrophysical Journal.

IXPE is a collaboration between NASA and the Italian Space Agency with partners and science collaborators in 12 countries. IXPE is led by Marshall.

NASA Shares Lessons Learned in Low Earth Orbit Through Payload Workshop

By Jessica Barnett

NASA welcomed commercial partners from around the globe to Marshall Space Flight Center for a three-day workshop last fall, highlighting what the agency has learned during its more than 20 years in Low Earth orbit.

Through tours, panels, and one-on-one discussions, the workshop provided an overview and best practices of what NASA does to prepare International Space Station payloads for operations, so commercial partners can leverage NASA’s knowledge and experience as they build their own space stations and presence in Low Earth orbit.

“We have so much history and knowledge, and we want to impart on them what we know so they can think about it, and see what applies to them and what doesn’t,” said Eleasa Kim, who serves as the Payload Operations Lead for NASA’s Commercial Low Earth Orbit Development Program, also known as CLDP, supporting Marshall’s Human Exploration Development and Operations Division.

NASA’s CLDP is supporting the development of commercially owned and operated Low Earth orbit destinations from which NASA, along with other customers, can purchase services and stimulate the growth of commercial activities. As commercial Low Earth orbit destinations become available, NASA intends to implement an orderly transition from current space station operations to these new commercial destinations.

More than 70 people joined the workshop in person and online. Attendees were able to listen to experts discuss a litany of topics, from a general overview of the payload life cycle to safety reviews and flight readiness checks to real-time support and anomaly response.

Among the attendees, was John Selmarten, senior manager, Payload Project Management at Axiom Space. Selmarten said the workshop offered invaluable help to the company.

“The CLDP workshop offered industry access to, and an overview of, NASA’s wide variety of subject matter experts, tools, and facilities currently utilized to operate payloads on the ISS,” Selmarten said. “This information is invaluable to Axiom Space as we begin the transformation of low-Earth orbit into a global marketplace through research, in-space manufacturing, and tech demos.”

For Alex Stuetz and Denis Healy of Los Angeles-based aerospace company Vast, it was an amazing opportunity to hear from people with decades of experience.

“I certainly benefited from the breadth of topics covered,” said Healy, who serves as Vast’s mission operations engineer II. “It wasn’t three or four very specific, niche areas, but there was a good scope of subjects covered, and the details and nuance as it relates to each.”

The pair also took part in the tours and one-on-one discussions made available through the workshop.

“It’s incredibly helpful to be able to have face-to-face conversations and get a tour of the facilities, to see the hardware,” said Stuetz, Vast’s mission manager. “It’s these types of events that really push everything forward rapidly and in a collaborative manner.”

Marshall team members were equally excited to share their knowledge with NASA’s commercial partners.

“It’s a chance to share and build something new, to continue the Low Earth orbit presence,” said Joe Kitchen, operations discipline lead for the Planning and Analysis Branch of the Payload Mission Operations Division at Marshall. “Commercializing is really the only way to enable it, so it’s cool to be part of this.”

Marty O’Toole, the Starlab payloads lead on the Voyager team, also shared his appreciation for the MSFC Payload Ops team and the workshop.

“It was a very informative briefing on all aspects of ISS payload operations, from early integration activities through planning, certification, real-time ops and return,” said O’Toole. “The presentation format with a group of experienced individuals assuming their CADRE (Cooperative Autonomous Distributed Robotic Exploration) roles helped to demonstrate and emphasize the detailed coordination needed across all the ops functions. This exercise stimulated lots of discussion and thinking about how Starlab can implement and streamline its operations program going forward.”

Kim explained that the workshop is the first of its kind for her team, which spent three months preparing, including dry runs on each Friday of the final month leading up to the workshop. In addition to preparing tours and panels, they arranged social events, networking opportunities, case studies with filmed simulations, and more for the commercial partners.

Brr, It’s Cold in Here! NASA’s Cryo Efforts Beyond the Atmosphere

Establishing sustained operations at the Moon and Mars presents a multitude of opportunities and challenges NASA has yet to encounter. Many of these activities require new technologies and processes to ensure the agency is prepared for its ambitious Artemis missions and those beyond.

One of those challenges is working with cryogenic fluids, meaning fluids existing in a liquid state between minus 238 degrees Fahrenheit and absolute zero (minus 460 F). These fluids – liquid hydrogen (the most difficult to work with), methane, and oxygen – are vital to spacecraft propulsion and life support systems. The fluids may also be produced in the future on the lunar and Martian surfaces via ISRU (in-situ resource utilization).

Human exploration in deep space requires storing large amounts of cryogenic fluids for weeks, months, or longer, as well as transferring between spacecraft or fuel depots in orbit and on the surface. Each aspect is challenging, and, to date, large amounts of cryogenic fluids have only been stored for hours in space. Engineers working in NASA’s Cryogenic Fluid Management, or CFM, Portfolio – led by Technology Demonstration Missions within the Space Technology Mission Directorate and managed at the agency’s Glenn Research Center and Marshall Space Flight Center – are solving those issues ahead of future missions.

“This is a task neither NASA, nor our partners, have ever done before,” said Lauren Ameen, deputy CFM Portfolio manager. “Our future mission concepts rely on massive amounts of cryogenic fluids, and we have to figure out how to efficiently use them over long durations, which requires a series of new technologies far exceeding today’s capabilities.”

For a cryogenic fluid to be useable, it must remain in a frigid, liquid state. However, the physics of space travel – moving in and out of sunlight and long stays in low gravity – make keeping those fluids in a liquid state and knowing how much is in the tank complicated.  

The heat sources in space ­– like the Sun and the spacecraft’s exhaust – create a hot environment inside and around storage tanks causing evaporation or “boiloff.” When fluid evaporates, it can no longer efficiently fuel a rocket engine. It also increases the risk of leakage or, even worse, a tank rupture.

Being unsure of how much gas is left in the tank isn’t how our explorers want to fly to Mars. Low gravity is challenging because the fuel wants to float around – also known as “slosh” – which makes accurately gauging the amount of liquid and transferring it very difficult.

“Previous missions using cryogenic propellants were in space for only a few days due to boiloff or venting losses,” Ameen noted. “Those spacecraft used thrust and other maneuvers to apply force to settle propellant tanks and enable fuel transfers. During Artemis, spacecraft will dwell in low gravity for much longer and need to transfer liquid hydrogen in space for the first time, so we must mitigate boiloff and find innovative ways to transfer and measure cryogenic propellants.”

NASA’s CFM portfolio encompasses 24 development activities and investments to reduce boiloff, improve gauging, and advance fluid transfer techniques for in-space propulsion, landers, and ISRU. There are four near-term efforts taking place on the ground, in near-Earth orbit, and soon on the lunar surface.  

Flight Demos

In 2020, NASA awarded four CFM-focused Tipping Point contracts to American industry – Eta Space, Lockheed Martin, SpaceX, and United Launch Alliance – to assist in developing and demonstrating CFM technologies in space. Each company is scheduled to launch its respective demonstration in either 2024 or 2025, performing multiple tests using liquid hydrogen to validate technologies and processes.

Radio Frequency Mass Gauge

To improve gauging, NASA has developed RFMG (Radio Frequency Mass Gauges) to allow for more accurate fluid measurement in low-gravity or low-thrust conditions. Engineers do this by measuring the electromagnetic spectrum, or radio waves, within a spacecraft’s tank throughout the mission, comparing them to fluid simulations to accurately gauge remaining fuel.

The RFMG has been proven in ground tests, sub-orbital parabolic flight, and on the International Space Station, and it will soon be tested on the Moon during an upcoming Commercial Lunar Payload Services flight with Intuitive Machines. Once demonstrated in the lunar environment, NASA will continue to develop and scale the technology to enable improved spacecraft and lander operations.

Cryocoolers

Cryocoolers act like heat exchangers for large propellant tanks to mitigate boiloff when combined with innovative tank insulation systems. With industry partners, like Creare, NASA has begun testing high-capacity cryocooler systems that pump the “working” fluid through a network of tubes installed on the tank to keep it cool. NASA plans to increase tank size and capabilities to meet mission requirements before conducting future flight demonstrations.

CryoFill

NASA is also developing a liquefaction system to turn gaseous oxygen into liquid oxygen on the surface of the Moon or Mars to refuel landers using propellant produced in situ. This approach uses various methods to cool oxygen down to critical temperature (at least minus 297 degrees Fahrenheit), where it condenses, turning from a gas to a liquid. Initial development and testing have proven NASA can do this efficiently, and the team continues to scale the technology to relevant tank sizes and quantities for future operations.

Ultimately, NASA efforts to develop and test CFM systems that are energy-, mass-, and cost-efficient are critical to the success of the agency’s ambitious missions to the Moon, Mars, and beyond.

Astronomers Find Spark of Star Birth Across Billions of Years

Four images from NASA’s Chandra X-ray Observatory and other telescopes represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe’s biggest galaxies, as described in a press release.

This research showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years.

This release includes composite images of four galaxy clusters, presented in a two-by-two grid. Each image features a hazy, purple cloud representing X-rays from hot gas observed by Chandra. The distant galaxies in and around the clouds of hot gas have been captured in optical data, and are shown in golden yellows with hints of vibrant cyan blue.
These images represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe’s biggest galaxies. Clusters of galaxies are the largest objects in the universe held together by gravity and contain huge amounts of hot gas seen in X-rays. This research, made using Chandra and other telescopes, showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years. In these images, X-rays from Chandra are shown along with optical data from Hubble.

Galaxy clusters are the largest objects in the universe held together by gravity and contain huge amounts of hot gas seen in X-rays. This hot gas weighs several times the total mass of all the stars in all the hundreds of galaxies typically found in galaxy clusters. In the four galaxy cluster images in this graphic, X-rays from hot gas detected by Chandra are in purple and optical data from NASA’s Hubble Space Telescope, mostly showing galaxies in the clusters, are yellow and cyan.

In this study, researchers looked at the brightest and most massive class of galaxies in the universe, called BCGs (brightest cluster galaxies), in the centers of 95 clusters of galaxies. The galaxy clusters chosen are themselves an extreme sample – the most massive clusters in a large survey using the SPT (South Pole Telescope), with funding support from the National Science Foundation and Department of Energy – and are located between 3.4 and 9.9 billion light-years from Earth.

The four galaxy clusters shown here at located at distances of 3.9 billion (SPT-CLJ0106-5943), 5.6 billion (SPT-CLJ0307-6225), 6.4 billion (SPT-CLJ0310-4647) and 7.7 billion (SPT-CLJ0615-5746) light-years from Earth, and the images are 1.7 million, 2 million, 2.4 million and 2.2 million light-years across, respectively. By comparison our galaxy is only about 100,000 light-years across.

In SPT-CLJ0307-6225 the BCG is near the bottom right of the image and in the other images they are near the centers. Some of the long, narrow features are caused by gravitational lensing, where mass in the clusters is warping the light from galaxies behind the clusters. The images have been rotated from standard astronomer’s configuration of North up by 20 degrees clockwise (SPT-CLJ0106-5943), 6.2 degrees counterclockwise (SPT-CLJ0307-6225), 29,2 degrees counterclockwise (SPT-CLJ0310-4647) and 24.2 degrees clockwise (SPT-CLJ0615-5746).

The team found that the precise trigger for stars to form in the galaxies that they studied is when the amount of disordered motion in the hot gas – a physical concept called “entropy” – falls below a critical threshold. Below this threshold, the hot gas inevitably cools to form new stars.

In addition to the X-ray data from Chandra X-ray Observatory and radio data from the SPT already mentioned, this result also used radio data from the Australia Telescope Compact Array, and the Australian SKA Pathfinder Telescope, infrared data from NASA’s WISE satellite, and several optical telescopes. The optical telescopes used in this study were the Magellan 6.5-m Telescopes, the Gemini South Telescope, the Blanco 4-m Telescope (DECam, MOSAIC-II) and the Swope 1m Telescope. A total of almost 50 days of Chandra observing time was used for this result.

Michael Caldazilla of MIT (Massachusetts Institute of Technology) presented these results at the 243rd meeting of the American Astronomical Society in New Orleans, Louisana. In addition, there is a paper submitted to The Astrophysical Journal led by Caldazilla on this result.

      Rocket Hardware for Future Artemis Flights Moved to Barge for Delivery to Kennedy
      NASA is making strides with the Artemis campaign as key components for the SLS (Space Launch System) rocket continue to make their way to NASA’s Kennedy Space Center. Teams with NASA and Boeing loaded the core stage boat-tail for Artemis III and the core stage engine section for Artemis IV onto the agency’s Pegasus barge at Michoud Assembly Facility on Aug. 28.
      The core stage engine section of the SLS (Space Launch System) rocket for Artemis IV is loaded onto the agency’s Pegasus barge at Michoud Assembly Facility on Aug. 28. The core stage hardware will be moved Kennedy’s Space Systems Processing Facility for outfitting.NASA/Justin Robert The core stage hardware joins the launch vehicle stage adapter for Artemis II, which was moved onto the barge at NASA’s Marshall Space Flight Center on Aug. 21. Pegasus will ferry the multi-mission rocket hardware more than 900 miles to the Space Coast of Florida. Teams with the NASA’s Exploration Ground Systems Program will prepare the launch vehicle stage adapter for Artemis II stacking operations inside the Vehicle Assembly Building, while the core stage hardware will be moved to Kennedy’s Space Systems Processing Facility for outfitting. Beginning with Artemis III, core stages will undergo final assembly at Kennedy.
      The launch vehicle stage adapter is essential for connecting the rocket’s core stage to the upper stage. It also shields sensitive avionics and electrical components in the rocket’s interim cryogenic propulsion stage from the intense vibrations and noise of launch.
      The boat-tail and engine section are crucial for the rocket’s functionality. The boat-tail extends from the engine section, fitting snugly to protect the rocket’s engines during launch. The engine section itself houses more than 500 sensors, 18 miles of cables, and key systems for fuel management and engine control, all packed into the bottom of the towering 212-foot core stage.
      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.

      25 Years Strong: NASA’s Student Launch Competition Accepting 2025 Proposals
      By Wayne Smith
      NASA’s Student Launch competition kicks off its 25th year with the release of the 2025 handbook, detailing how teams can submit proposals by Sept. 11 for the event scheduled next spring near NASA’s Marshall Space Flight Center.
      Student Launch is an annual competition challenging middle school, high school, and college students to design, build, test, and launch a high-powered amateur rocket with a scientific or engineering payload. After a team is selected, they must meet documentation milestones and undergo detailed reviews throughout the school year.
      NASA’s Student Launch, a STEM competition, officially kicks off its 25th anniversary with the 2025 handbook.NASA Each year, NASA updates the university payload challenge to reflect current scientific and exploration missions. For the 2025 season, the payload challenge will again take inspiration from the Artemis missions, which seek to land the first woman and first person of color on the Moon.
      As Student Launch celebrates its 25th anniversary, the payload challenge will include “reports” from STEMnauts, non-living objects representing astronauts. The 2024 challenge tasked teams with safely deploying a lander mid-air for a group of four STEMnauts using metrics to support a survivable landing. The lander had to be deployed without a parachute and had a minimum weight limit of five pounds.
      “This year, we’re shifting the focus to communications for the payload challenge,” said John Eckhart, technical coordinator for Student Launch at Marshall. “The STEMnaut ‘crew’ must relay real-time data to the student team’s mission control. This helps connect Student Launch with the Artemis missions when NASA lands astronauts on the Moon.”
      Thousands of students participated in the 2024 Student Launch competition – making up 70 teams representing 24 states and Puerto Rico. Teams launched their rockets to an altitude between 4,000 and 6,000 feet, while attempting to make a successful landing and executing the payload mission. The University of Notre Dame was the overall winner of the 2024 event, which culminated with a launch day open to the public.
      Student Launch began in 2000 when former Marshall Director Art Stephenson started a student rocket competition at the center. It started with just two universities in Huntsville competing – Alabama A&M University and the University of Alabama in Huntsville – but has continued to soar. Since its inception, thousands of students have participated in the agency’s STEM competition, with many going on to a career with NASA.
      “This remarkable journey, spanning a quarter of a century, has been a testament to the dedication, ingenuity, and passion of countless students, educators, and mentors who have contributed to the program’s success,” Eckhart said. “NASA Student Launch has been at the forefront of experiential education, providing students from middle school through university with unparalleled opportunities to engage in real-world engineering and scientific research. The program’s core mission – to inspire and cultivate the next generation of aerospace professionals and space explorers – has not only been met but exceeded in ways we could have only dreamed of.”
      To encourage students to pursue degrees and careers in STEM (science, technology, engineering, and math), Marshall’s Office of STEM Engagement hosts Student Launch, providing them with real-world experiences. Student Launch is one of NASA’s nine Artemis Student Challenges – a variety of activities that expose students to the knowledge and technology required to achieve the goals of Artemis. 
      In addition to the NASA Office of STEM Engagement’s Next Generation STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition. 
      “These bright students rise to a nine-month challenge for Student Launch that tests their skills in engineering, design, and teamwork,” said Kevin McGhaw, director of NASA’s Office of STEM Engagement Southeast Region. “They are the Artemis Generation, the future scientists, engineers, and innovators who will lead us into the future of space exploration.”

      NASA Expands Human Exploration Rover Challenge to Middle Schools
      By Wayne Smith
      Following a 2024 competition that garnered international attention, NASA is expanding its Human Exploration Rover Challenge (HERC) to include a remote control division and inviting middle school students to participate.
      The 31st annual competition is scheduled for April 11-12, 2025, at the U.S. Space & Rocket Center, near NASA’s Marshall Space Flight Center. HERC is managed by NASA’s Southeast Regional Office of STEM Engagement at Marshall. The HERC 2025 Handbook has been released, with guidelines for the new remote control (RC) division – ROVR (Remote-Operated Vehicular Research) – and detailing updates for the human-powered division.
      The cover of the HERC 2025 handbook, which is now available online.NASA “Our RC division significantly lowers the barrier to entry for schools who don’t have access to manufacturing facilities, have less funding, or who are motivated to compete but don’t have the technical mentorship required to design and manufacture a safe human-powered rover,” said Chris Joren, HERC technical coordinator. “We are also opening up HERC to middle school students for the first time. The RC division is inherently safer and less physically intensive, so we invite middle school teams and organizations to submit a proposal to be a part of HERC 2025.”
      Another change for 2025 is the removal of task sites on the course for the human-powered rover division, allowing teams to focus on their rover’s design. Recognized as NASA’s leading international student challenge, the 2025 challenge aims to put competitors in the mindset of the Artemis campaign as they pitch an engineering design for a lunar terrain vehicle – they are astronauts piloting a vehicle, exploring the lunar surface while overcoming various obstacles.
      “The HERC team wanted to put together a challenge that allows students to gain 21st century skills, workforce readiness skills, and skills that are transferable,” said Vemitra Alexander, HERC activity lead. “The students have opportunities to learn and apply the engineering design process model, gain public speaking skills, participate in community outreach, and learn the art of collaborating with their peers. I am very excited about HERC’s growth and the impact it has on the students we serve nationally and internationally.”
      Students interested in designing, developing, building, and testing rovers for Moon and Mars exploration are invited to submit their proposals to NASA through Sept. 19.
      More than 1,000 students with 72 teams from around the world participated in the 2024 challenge as HERC celebrated its 30th anniversary as a NASA competition. Participating teams represented 42 colleges and universities and 30 high schools from 24 states, the District of Columbia, Puerto Rico, and 13 other nations from around the world.
      “We saw a massive jump in recognition, not only from within the agency as NASA Chief Technologist A.C. Charania attended the event, but with several of our international teams meeting dignitaries and ambassadors from their home countries to cheer them on,” Joren said. “The most impressive thing will always be the dedication and resilience of the students and their mentors. No matter what gets thrown at these students, they still roll up to the start line singing songs and waving flags.”
      HERC is one of NASA’s eight Artemis Student Challenges reflecting the goals of the Artemis campaign, which seeks to land the first woman and first person of color on the Moon while establishing a long-term presence for science and exploration. NASA uses such challenges to encourage students to pursue degrees and careers in the STEM fields of science, technology, engineering, and mathematics. 
      Since its inception in 1994, more than 15,000 students have participated in HERC – with many former students now working at NASA, or within the aerospace industry.

      New NASA Sonifications Listen to the Universe’s Past
      A quarter of a century ago, NASA released the “first light” images from the agency’s Chandra X-ray Observatory. This introduction to the world of Chandra’s high-resolution X-ray imaging capabilities included an unprecedented view of Cassiopeia A, the remains of an exploded star located about 11,000 light-years from Earth. Over the years, Chandra’s views of Cassiopeia A have become some of the telescope’s best-known images.
      To mark the anniversary of this milestone, new sonifications of three images – including Cassiopeia A (Cas A) – are being released. Sonification is a process that translates astronomical data into sound, similar to how digital data are more routinely turned into images. This translation process preserves the science of the data from its original digital state but provides an alternative pathway to experiencing the data.
      Sonifications of three images have been released to mark the 25th anniversary of Chandra’s “First Light” image. For Cassiopeia A, which was one of the first objects observed by Chandra, X-ray data from Chandra and infrared data from Webb have been translated into sounds, along with some Hubble data. The second image in the sonification trio, 30 Doradus, also contains Chandra and Webb data. NGC 6872 contains data from Chandra as well as an optical image from Hubble. Each of these datasets have been mapped to notes and sounds based on properties observed by these telescopes.NASA/CXC/SAO/K.Arcand, SYSTEM Sounds (M. Russo, A. Santaguida) This sonification of Cas A features data from Chandra as well as NASA’s James Webb, Hubble, and retired Spitzer space telescopes. The scan starts at the neutron star at the center of the remnant, marked by a triangle sound, and moves outward. Astronomers first saw this neutron star when Chandra’s inaugural observations were released 25 years ago this week. Chandra’s X-rays also reveal debris from the exploded star that is expanding outward into space. The brighter parts of the image are conveyed through louder volume and higher pitched sounds. X-ray data from Chandra are mapped to modified piano sounds, while infrared data from Webb and Spitzer, which detect warmed dust embedded in the hot gas, have been assigned to various string and brass instruments. Stars that Hubble detects are played with crotales, or small cymbals.
      Another new sonification features the spectacular cosmic vista of 30 Doradus, one of the largest and brightest regions of star formation close to the Milky Way. This sonification again combines X-rays from Chandra with infrared data from Webb. As the scan moves from left to right across the image, the volume heard again corresponds to the brightness seen. Light toward the top of the image is mapped to higher pitched notes. X-rays from Chandra, which reveal gas that has been superheated by shock waves generated by the winds from massive stars, are heard as airy synthesizer sounds. Meanwhile, Webb’s infrared data show cooler gas that provides the raw ingredients for future stars. These data are mapped to a range of sounds including soft, low musical pitches (red regions), a wind-like sound (white regions), piano-like synthesizer notes indicating very bright stars, and a rain-stick sound for stars in a central cluster.
      The final member of this new sonification triumvirate is NGC 6872, a large spiral galaxy that has two elongated arms stretching to the upper right and lower left, which is seen in an optical light view from Hubble. Just to the upper left of NGC 6872 appears another smaller spiral galaxy. These two galaxies, each of which likely has a supermassive black hole at the center, are being drawn toward one another. As the scan sweeps clockwise from 12 o’clock, the brightness controls the volume and light farther from the center of the image is mapped to higher-pitched notes. Chandra’s X-rays, represented in sound by a wind-like sound, show multimillion-degree gas that permeates the galaxies. Compact X-ray sources from background galaxies create bird-like chirps. In the Hubble data, the core of NGC 6872 is heard as a dark low drone, and the blue spiral arms (indicating active star formation) are audible as brighter, more highly pitched tones. The background galaxies are played as a soft pluck sound while the bright foreground star is accompanied by a crash cymbal.
      More information about the NASA sonification project through Chandra, which is made in partnership with NASA’s Universe of Learning, can be found here. The collaboration was driven by visualization scientist Kimberly Arcand (CXC), astrophysicist Matt Russo, and musician Andrew Santaguida, (both of the SYSTEM Sounds project), along with consultant Christine Malec.
      NASA’s Universe of Learning materials are based upon work supported by NASA under cooperative agreement award number NNX16AC65A to the Space Telescope Science Institute, working in partnership with Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and the Jet Propulsion Laboratory.
      Chandra, managed for NASA by the agency’s Marshall Space Flight Center in partnership with the CXC, is one of NASA’s Great Observatories, along with the Hubble Space Telescope and the now-retired Spitzer Space Telescope and Compton Gamma Ray Observatory. It was first proposed to NASA in 1976 by Riccardo Giacconi, recipient of the 2002 Nobel Prize for Physics based on his contributions to X-ray astronomy, and Harvey Tananbaum, who would later become the first director of the Chandra X-ray Center. Chandra was named in honor of the late Nobel laureate Subrahmanyan Chandrasekhar, who earned the Nobel Prize in Physics in 1983 for his work explaining the structure and evolution of stars.

      Europa Clipper Gets Set of Super-Size Solar Arrays
      NASA’s Europa Clipper spacecraft recently got outfitted with a set of enormous solar arrays at the agency’s Kennedy Space Center. Each measuring about 46½ feet long and about 13½ feet high, the arrays are the biggest NASA has ever developed for a planetary mission. They must be large so they can soak up as much sunlight as possible during the spacecraft’s investigation of Jupiter’s moon Europa, which is five times farther from the Sun than Earth is.
      NASA’s Europa Clipper is seen Aug. 21 at the agency’s Kennedy Space Center. Engineers and technicians deployed and tested the giant solar arrays to be sure they will operate in flight.NASA/Frank Michaux The arrays have been folded up and secured against the spacecraft’s main body for launch, but when they’re deployed in space, Europa Clipper will span more than 100 feet – a few feet longer than a professional basketball court. The “wings,” as the engineers call them, are so big that they could only be opened one at a time in the clean room of Kennedy’s Payload Hazardous Servicing Facility, where teams are readying the spacecraft for its launch period, which opens Oct. 10. 
      Meanwhile, engineers continue to assess tests conducted on the radiation hardiness of transistors on the spacecraft. Longevity is key, because the spacecraft will journey more than five years to arrive at the Jupiter system in 2030. As it orbits the gas giant, the probe will fly by Europa multiple times, using a suite of science instruments to find out whether the ocean underneath its ice shell has conditions that could support life.
      Powering those flybys in a region of the solar system that receives only 3% to 4% of the sunlight Earth gets, each solar array is composed of five panels. Designed and built at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Airbus in Leiden, Netherlands, they are much more sensitive than the type of solar arrays used on homes, and the highly efficient spacecraft will make the most of the power they generate.
      NASA’s Europa Clipper is seen in a clean room at Kennedy Space Center after engineers and technicians tested and stowed the spacecraft’s giant solar arrays.NASA/Frank Michaux At Jupiter, Europa Clipper’s arrays will together provide roughly 700 watts of electricity, about what a small microwave oven or a coffee maker needs to operate. On the spacecraft, batteries will store the power to run all of the electronics, a full payload of science instruments, communications equipment, the computer, and an entire propulsion system that includes 24 engines.
      While doing all of that, the arrays must operate in extreme cold. The hardware’s temperature will plunge to minus 400 degrees Fahrenheit when in Jupiter’s shadow. To ensure that the panels can operate in those extremes, engineers tested them in a specialized cryogenic chamber at Liège Space Center in Belgium.
      “The spacecraft is cozy. It has heaters and an active thermal loop, which keep it in a much more normal temperature range,” said APL’s Taejoo Lee, the solar array product delivery manager. “But the solar arrays are exposed to the vacuum of space without any heaters. They’re completely passive, so whatever the environment is, those are the temperatures they get.”
      About 90 minutes after launch, the arrays will unfurl from their folded position over the course of about 40 minutes. About two weeks later, six antennas affixed to the arrays will also deploy to their full size. The antennas belong to the radar instrument, which will search for water within and beneath the moon’s thick ice shell, and they are enormous, unfolding to a length of 57.7 feet, perpendicular to the arrays.
      “At the beginning of the project, we really thought it would be nearly impossible to develop a solar array strong enough to hold these gigantic antennas,” Lee said. “It was difficult, but the team brought a lot of creativity to the challenge, and we figured it out.”
      Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its 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, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with APL for NASA’s Science Mission Directorate. APL designed the main spacecraft body 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, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.

      Work is Underway on NASA’s Next-Generation Asteroid Hunter
      NASA’s new asteroid-hunting spacecraft is taking shape at NASA’s Jet Propulsion Laboratory. Called NEO Surveyor (Near-Earth Object Surveyor), this cutting-edge infrared space telescope will seek out the hardest-to-find asteroids and comets that might pose a hazard to our planet. In fact, it is the agency’s first space telescope designed specifically for planetary defense.
      Targeting launch in late 2027, the spacecraft will travel a million miles to a region of gravitational stability – called the L1 Lagrange point – between Earth and the Sun. From there, its large sunshade will block the glare and heat of sunlight, allowing the mission to discover and track near-Earth objects as they approach Earth from the direction of the Sun, which is difficult for other observatories to do. The space telescope also may reveal asteroids called Earth Trojans, which lead and trail our planet’s orbit and are difficult to see from the ground or from Earth orbit.
      A mirror that was later installed inside NASA’s Near-Earth Object Surveyor shows a reflection of principal optical engineer Brian Monacelli during an inspection of the mirror’s surface at the agency’s Jet Propulsion Laboratory on July 17.NASA/JPL-Caltech NEO Surveyor relies on cutting-edge detectors that observe two bands of infrared light, which is invisible to the human eye. Near-Earth objects, no matter how dark, glow brightly in infrared as the Sun heats them. Because of this, the telescope will be able to find dark asteroids and comets, which don’t reflect much visible light. It also will measure those objects, a challenging task for visible-light telescopes that have a hard time distinguishing between small, highly reflective objects and large, dark ones.
      “NEO Surveyor is optimized to help us to do one specific thing: enable humanity to find the most hazardous asteroids and comets far enough in advance so we can do something about them,” said Amy Mainzer, survey director for NEO Surveyor and a professor at the University of California, Los Angeles. “We aim to build a spacecraft that can find, track, and characterize the objects with the greatest chance of hitting Earth. In the process, we will learn a lot about their origins and evolution.”
      The spacecraft’s only instrument is its telescope. About the size of a washer-and-dryer set, the telescope’s blocky aluminum body, called the optical bench, was built in a JPL clean room. Known as a three-mirror anastigmat telescope, it will rely on curved mirrors to focus light onto its infrared detectors in such a way that minimizes optical aberrations.
      “We have been carefully managing the fabrication of the spacecraft’s telescope mirrors, all of which were received in the JPL clean room by July,” said Brian Monacelli, principal optical engineer at JPL. “Its mirrors were shaped and polished from solid aluminum using a diamond-turning machine. Each exceeds the mission’s performance requirements.”
      Monacelli inspected the mirror surfaces for debris and damage, then JPL’s team of optomechanical technicians and engineers attached the mirrors to the telescope’s optical bench in August. Next, they will measure the telescope’s performance and align its mirrors.
      Complementing the mirror assembly are the telescope’s mercury-cadmium-telluride detectors, which are similar to the detectors used by NASA’s recently retired NEOWISE (short for Near-Earth Object Wide-field Infrared Survey Explorer) mission. An advantage of these detectors is that they don’t necessarily require cryogenic coolers or cryogens to lower their operational temperatures in order to detect infrared wavelengths. Cryocoolers and cryogens can limit the lifespan of a spacecraft. NEO Surveyor will instead keep its cool by using its large sunshade to block sunlight from heating the telescope and by occupying an orbit beyond that of the Moon, minimizing heating from Earth.
      A technician operates articulating equipment to rotate NEO Surveyor’s aluminum optical bench – part of the spacecraft’s telescope – in a clean room at NASA’s Jet Propulsion Laboratory.NASA/JPL-Caltech The telescope will eventually be installed inside the spacecraft’s instrument enclosure, which is being assembled in JPL’s historic High Bay 1 clean room where NASA missions such as Voyager, Cassini, and Perseverance were constructed. Fabricated from dark composite material that allows heat to escape, the enclosure will help keep the telescope cool and prevent its own heat from obscuring observations.
      Once it is completed in coming weeks, the enclosure will be tested to make sure it can withstand the rigors of space exploration. Then it will be mounted on the back of the sunshade and atop the electronic systems that will power and control the spacecraft.
      “The entire team has been working hard for a long time to get to this point, and we are excited to see the hardware coming together with contributions from our institutional and industrial collaborators from across the country,” said Tom Hoffman, NEO Surveyor’s project manager at JPL. “From the panels and cables for the instrument enclosure to the detectors and mirrors for the telescope — as well as components to build the spacecraft — hardware is being fabricated, delivered, and assembled to build this incredible observatory.”
      Assembly of NEO Surveyor can be viewed 24 hours a day, seven days a week, via JPL’s live cam.
      The NEO Surveyor mission marks a major step for NASA toward reaching its U.S. Congress-mandated goal to discover and characterize at least 90% of the near-Earth objects more than 460 feet across that come within 30 million miles of our planet’s orbit. Objects of this size can cause significant regional damage, or worse, should they impact the Earth.
      The mission is tasked by NASA’s Planetary Science Division within the Science Mission Directorate; program oversight is provided by the Planetary Defense Coordination Office, which was established in 2016 to manage the agency’s ongoing efforts in planetary defense. NASA’s Planetary Missions Program Office at the agency’s Marshall Space Flight Center provides program management for NEO Surveyor.
      The project is being developed by JPL and is led by survey director Amy Mainzer at UCLA. Established aerospace and engineering companies have been contracted to build the spacecraft and its instrumentation, including BAE Systems, Space Dynamics Laboratory, and Teledyne. The Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder will support operations, and IPAC-Caltech in Pasadena, California, is responsible for processing survey data and producing the mission’s data products. Caltech manages JPL for NASA.

Learn how to stream NASA programming through a variety of platforms including social media.
      NASA astronauts Butch Wilmore and Suni Williams launched aboard Boeing’s Starliner spacecraft on June 5 for its first crewed flight, arriving at the space station on June 6. As Starliner approached the orbiting laboratory, NASA and Boeing identified helium leaks and experienced issues with the spacecraft reaction control thrusters. For the safety of the astronauts, NASA announced on Aug. 24 that Starliner will return to Earth from the station without a crew. Wilmore and Williams will remain aboard the station and return home in February 2025 aboard the SpaceX Dragon spacecraft with two other crew members assigned to NASA’s SpaceX Crew-9 mission.

      Gator Speaks
      NASA’s Stennis Space Center keeps writing new history, and the front office announcement in August delights this ‘ol Gator!
      The news delights me because the south Mississippi NASA center will continue to be in good hands with Christine Powell serving as the new deputy director. And talk about perfect timing – announcement of the selection came just a few weeks before the celebration of Women’s Equality Day on Aug. 26.
      Gator SpeaksNASA/Stennis In her new role, Powell now is responsible, along with NASA Stennis Director John Bailey, for coordinating all the rocket propulsion test capabilities onsite, along with managing the overall NASA center.
      As the nation’s largest – and premier – propulsion test site, NASA Stennis supports test operations for both government and commercial aerospace companies. Powell’s depth of knowledge positions her perfectly for this new challenge.
      Her record shows that she knows the ins-and-outs of NASA Stennis and is very-well versed on propulsion testing. Her career is also a testament to NASA developing its skilled workforce. Powell started as an intern at NASA Stennis in 1991. Following the internship, she worked as an instrumentation engineer and systems integration engineer before moving into leadership positions in 2004.
      All in all, Powell illustrates perfectly the important role women play at NASA Stennis – in positions and roles all across the center. Women are a vital part of the NASA Stennis team, contributing to every area of the center’s work and mission.
      NASA Stennis’ aim in the future is to operate as a multi-user propulsion testing enterprise that accelerates the development of aerospace systems and services by government and industry.
      This Gator has witnessed many successful endeavors at NASA Stennis, and I am confident that Powell’s new role will have her adding value to this endeavor.
      Just as the focus was on women’s equality last month, September provides a time to celebrate the hard work of all with Labor Day on the first Monday of the month. As we move forward, the newest deputy director’s journey at NASA Stennis proves that work is not merely a means to an end, but also a journey to realize one’s full potential.
