Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA marked a key milestone Feb. 18 with installation of RS-25 engine No. E20001, the first new production engine to help power the SLS (Space Launch System) rocket on future Artemis missions to the Moon.
The engine, built by lead SLS engines contractor L3Harris (formerly Aerojet Rocketdyne), was installed on the Fred Haise Test Stand in preparation for acceptance testing next month. It represents the first of 24 new flight engines being built for missions, beginning with Artemis V.

During missions to the Moon, RS-25 engines fire for about 500 seconds and up to the 111% power level to help launch SLS, with the Orion spacecraft, into orbit.
The engine arrived at the test stand from the L3Harris Engine Assembly Facility on the engine transport trailer before being lifted onto the vertical engine installer (VEI) on the west side deck. After rolling the engine into the stand, the team used the VEI to raise and secure it in place.
The upcoming acceptance test follows two certification test series that helped verify the new engine production process and components meet all performance requirements. Four RS-25 engines help launch SLS, producing up to 2 million pounds of combined thrust.
All RS-25 engines for Artemis missions are tested and proven flightworthy at NASA Stennis prior to use. RS-25 tests are conducted by a team of operators from NASA, L3Harris, and Syncom Space Services, prime contractor for site facilities and operations.

“We’re trying to tap into the community college talent pool to bring new students to the table for aeronautics,” said Steven Holz, who manages the USRC award process. “Innovation comes from everywhere, and people with different viewpoints, educational backgrounds, and experiences like those in our community colleges are also interested in aeronautics and looking to make a difference.”
Real World Research Awards
Through USRC, students interact with real-world aspects of the research ecosystem both in and out of the laboratory. They will manage their own research projects, utilize state-of-the-art technology, and work alongside accomplished aeronautical researchers. Students are expected to make unique contributions to NASA’s research priorities.
USRC provides more than just experience in technical research.
Each team of students selected receives a USRC grant from NASA – and is tasked with the additional challenge of raising funds from the public through student-led crowdfunding. The process helps students develop skills in entrepreneurship and public communication.
The new university teams and research topics are:
Cerritos Community College
“Project F.I.R.E. (Fire Intervention Retardant Expeller)” will explore how to mitigate wildfires by using environmentally friendly fire-retardant pellets dropped from drones. Cerritos Community College’s team includes lead Angel Ortega Barrera as well as Larisa Mayoral, Paola Mayoral Jimenez, Jenny Rodriguez, Logan Stahl, and Juan Villa, with faculty mentor Janet McLarty-Schroeder. This team also successfully participated with the same research topic in in NASA’s Gateway to Blue Skies competition, which aims to expand engagement between the NASA’s University Innovation project and universities, industry, and government partners.
Colorado School of Mines
The project “Design and Prototyping of a 9-phase Dual-Rotor Motor for Supersonic Electric Turbofan” will work on a scaled-down prototype for an electric turbofan for supersonic aircraft. The Colorado School of Mines team includes lead Mahzad Gholamian as well as Garret Reader, Mykola Mazur, and Mirali Seyedrezaei, with faculty mentor Omid Beik.
Complete details on USRC awardees and solicitations, such as what to include in a proposal and how to submit it, are available on the NASA Aeronautics Research Mission Directorate solicitation page.

“I’m hopeful anyone, regardless of their scientific background, could read a Hubble post and understand the gist of it and be interested in it,” said Elizabeth Tammi, social media lead for the Hubble Space Telescope. “I also read our stories with the eye of the potential audience member: What are they going to care about? What is going to bring them into this story? What is going to make them want to read more?”Credits: Courtesy of Elizabeth Tammi Name: Elizabeth Tammi
Title: Hubble Space Telescope Social Media Lead
Formal Job Classification: Communications Specialist
Organization: Hubble Space Telescope Operations (Code 441)
What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
I am the social media lead for the Hubble Space Telescope mission at Goddard. In short, Hubble is an orbiting observatory that’s been in low-Earth orbit for more than 30 years. It’s one of NASA’s flagship missions, probably one of its most iconic missions. Hubble has shaped our understanding of how we imagine the universe — visually how we think about it.
I run Hubble’s Twitter, Facebook, Instagram, and Flickr, along with various other multimedia and communications tasks. We’re a very close-knit team, so we collaborate a lot, both within our team, and with other missions across the agency as well.
I’m primarily focused on social media and figuring out how are we going to share our news. On any given day, I might also be working on a script, editing news releases, or working with other accounts on social media campaigns. It’s different every day, which I really like.
What is your educational background?
I went to Mercer University, which is in Macon, Georgia. I graduated in 2020 with a degree in journalism and creative writing. There, they have a great program called the Center for Collaborative Journalism, which allowed us to work in newsrooms for academic credit. That was really useful, especially in this field, getting that hands-on experience and getting published from my freshman year on. I was eventually able to intern at Goddard the summer before my senior year. I really don’t think that would have been possible if I hadn’t had the audio production experience that Mercer allowed me to get, along with just all aspects of journalism, media, and communications.
“Hubble is one of NASA’s flagship missions, probably one of its most iconic missions,” said Elizabeth Tammi, social media lead for the Hubble Space Telescope. “Hubble has shaped our understanding of how we imagine the universe — visually how we think about it.”Credits: Courtesy of Elizabeth Tammi How does your writing experience contribute to your role with Hubble?
I know how to write accessibly and in a straightforward manner. I’m hopeful anyone, regardless of their scientific background, could read a post and understand the gist of it and be interested in it. That’s the goal. I try to come up with interesting turns of phrase when I can. I also read our stories with the eye of the potential audience member: What are they going to care about? What is going to bring them into this story? What is going to make them want to read more?
Outside work, you’ve written and published books. What inspired you to decide to write?
There’s not a day I can remember where I wasn’t absolutely infatuated with books. I think my parents read to me long before I could even understand them. It was just always such a huge part of my life — and I loved, loved, loved reading. When I realized that actual people wrote books, then I knew I wanted to write. To be clear, I didn’t take real steps toward that until I was about 15, 16-ish years old, because I guess in my mind, I still had this idea that authors were more than human.
I’ve since had two novels published. Both are in the fantasy genre and earned complimentary reviews; my second novel even earned a Moonbeam Children’s Book Award.
“I know it can be intimidating, to think about NASA as a place to intern,” said Hubble Space Telescope social media lead Elizabeth Tammi. “If you have any interest in space, I think that’s the most important part: People who are passionate and interested in our space program.”Credits: Courtesy of Elizabeth Tammi What do you most enjoy about sharing the Hubble story?
I think my favorite part is reading the comments that we get from the public, just because everyone has been so supportive of the telescope. Social media can put on display the best and worst aspects of humanity. It’s very nice to see this supportive corner of the Internet.
So far, what I’ve really enjoyed was our “Deep Field Week” social media campaign, which was around the 25th anniversary of the Hubble Deep Field image . To the unaided eye, this was a seemingly empty patch of sky. Hubble revealed it has countless galaxies. It was a really staggering finding and definitely was a huge cultural shift in how we think about our universe.
Previously, you were a NASA intern from the Summer of 2019 to May 2020. How has that experience shaped your current role?
It was absolutely vital. I don’t think I would be here in this position without that internship experience. It was the summer before my senior year of college. I got to go up to Goddard for summer 2019 and I was working primarily as an audio production intern, though the internship afforded me the opportunity to contribute to the newsroom’s work overall.
I worked with Katie Atkinson, who I also went to college with, and we got to work on the 50th anniversary of the Apollo 11 mission. One of my primary tasks that summer was working on an oral history campaign tied to Apollo 11’s 50th anniversary . We encouraged people from all over to send in audio accounts of what they remember experiencing when Apollo 11 landed on the Moon in 1969. Or, if they didn’t remember seeing it as it happened, how did the landing affect them and their view of the world, or their career aspirations, or if they have family stories tied to Apollo.
If I could describe my NASA experience with a book title, it would be the term “Galaxy Brain.” It’s when you have a normal thought but then you think harder, and it gets bigger. From the idea of constantly feeling mind-blown by the work that’s going on around me to being part of it makes me feel, “Oh my gosh!” This “Galaxy Brain” imagery symbolizes the enormous magnitude of everything that is interesting and mysterious. It’s just something that’s constantly engaging.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The G-IV aircraft flies overhead in the Mojave Desert near NASA’s Armstrong Flight Research Center in Edwards, California. Baseline flights like this one occurred in June 2024, and future flights in service of science research will benefit from the installment of the Soxnav navigational system, developed in collaboration with NASA’s Jet Propulsion Laboratory in Southern California and the Bay Area Environmental Research Institute in California’s Silicon Valley. This navigational system provides precise, economical aircraft guidance for a variety of aircraft types moving at high speeds.NASA/Carla Thomas NASA and its partners recently tested an aircraft guidance system that could help planes maintain a precise course even while flying at high speeds up to 500 mph. The instrument is Soxnav, the culmination of more than 30 years of development of aircraft navigation systems.
NASA’s G-IV aircraft flew its first mission to test this navigational system from NASA’s Armstrong Flight Research Center in Edwards, California, in December 2024. The team was composed of engineers from NASA Armstrong, NASA’s Jet Propulsion Laboratory in Southern California, and the Bay Area Environmental Research Institute (BAERI) in California’s Silicon Valley.
“The objective was to demonstrate this new system can keep a high-speed aircraft within just a few feet of its target track, and to keep it there better than 90% of the time,” said John Sonntag, BAERI independent consultant co-developer of Soxnav.
With 3D automated steering guidance, Soxnav provides pilots with a precision approach aid for landing in poor visibility. Previous generations of navigational systems laid the technical baseline for Soxnav’s modern, compact, and automated iteration.
“The G-IV is currently equipped with a standard autopilot system,” said Joe Piotrowski Jr., operations engineer for the G-IV. “But Soxnav will be able to create the exact level flight required for Next Generation Airborne Synthetic Aperture Radar (AirSAR-NG) mission success.”
Jose “Manny” Rodriguez adjusts the Soxnav instrument onboard the G-IV aircraft in December 2024. As part of the team of experts, Rodriguez ensures that the electronic components of this instrument are installed efficiently. His expertise will help bring the innovative navigational guidance of the Soxnav system to the G-IV and the wider airborne science fleet at NASA. Precision guidance provided by the Soxnav enables research aircraft like the G-IV to collect more accurate, more reliable Earth science data to scientists on the ground.NASA/Steve Freeman Guided by Soxnav, the G-IV may be able to deliver better, more abundant, and less expensive scientific information. For instance, the navigation tool optimizes observations by AirSAR-NG, an instrument that uses three radars simultaneously to observe subtle changes in the Earth’s surface. Together with the Soxnav system, these three radars provide enhanced and more accurate data about Earth science.
“With the data that can be collected from science flights equipped with the Soxnav instrument, NASA can provide the general public with better support for natural disasters, tracking of food and water supplies, as well as general Earth data about how the environment is changing,” Piotrowski said.
Ultimately, this economical flight guidance system is intended to be used by a variety of aircraft types and support a variety of present and future airborne sensors. “The Soxnav system is important for all of NASA’s Airborne Science platforms,” said Fran Becker, project manager for the G-IV AirSAR-NG project at NASA Armstrong. “The intent is for the system to be utilized by any airborne science platform and satisfy each mission’s goals for data collection.”
In conjunction with the other instruments outfitting the fleet of airborne science aircraft, Soxnav facilitates the generation of more abundant and higher quality scientific data about planet Earth. With extreme weather events becoming increasingly common, quality Earth science data can improve our understanding of our home planet to address the challenges we face today, and to prepare for future weather events.
“Soxnav enables better data collection for people who can use that information to safeguard and improve the lives of future generations,” Sonntag said.
