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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA / Getty Images NASA has selected two new university student teams to participate in real-world aviation research challenges meant to transform the skies above our communities.
The research awards were made through NASA’s University Student Research Challenge (USRC), which provides students with opportunities to contribute to NASA’s flight research goals.
This round is notable for including USRC’s first-ever award to a community college: Cerritos Community College.
We’re trying to tap into the community college talent pool to bring new students to the table for aeronautics.

NASA Project Manager
“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.

Eclipses to Auroras: Eclipse Ambassadors Experience Winter Field School in Alaska
In 2023 and 2024, two eclipses crossed the United States, and the NASA Science Activation program’s Eclipse Ambassadors Off the Path project invited undergraduate students and amateur astronomers to join them as “NASA Partner Eclipse Ambassadors”. This opportunity to partner with NASA, provide solar viewing glasses, and share eclipse knowledge with underserved communities off the central paths involved:
Partnering with an undergraduate/amateur astronomer Taking a 3-week cooperative course (~12 hours coursework) Engaging their communities with eclipse resources by reaching 200+ people These Eclipse Ambassador partnerships allowed participants to grow together as they learned new tools and techniques for explaining eclipses and engaging with the public, and Eclipse Ambassadors are recognized for their commitment to public engagement.
In January 2025, the Eclipse Ambassadors Off the Path project held a week-long Heliophysics Winter Field School (WFS), a culminating Heliophysics Big Year experience for nine undergraduate and graduate Eclipse Ambassadors. The WFS exposed participants to career opportunities and field experience in heliophysics, citizen science, and space physics. The program included expert lectures on space physics, aurora, citizen science, and instrumentation, as well as hands-on learning opportunities with Poker Flat Rocket Range, the Museum of the North, aurora chases, and more. Students not only learned about heliophysics, they also actively participated in citizen science data collection using a variety of instruments, as well as the Aurorasaurus citizen science project app. Interactive panels on career paths helped prepare them to pursue relevant careers.
One participant, Sophia, said, “This experience has only deepened my passion for heliophysics, science communication, and community engagement.” Another participant, Feras, reflected, “Nine brilliant students from across the country joined a week-long program at the University of Alaska Fairbanks’ (UAF) Geophysical Institute, where we attended multiple panels on solar and space physics, spoke to Athabaskan elders on their connection to the auroras, and visited the Poker Flat Research Range to observe the stunning northern lights.”
This undertaking would not have been possible without the coordination, planning, leadership of many. Principal Investigators included Vivian White (Eclipse Ambassadors, Astronomical Society of the Pacific, ASP) and Dr. Elizabeth McDonald (Aurorasaurus, NASA GSFC). Other partners included Lynda McGilvary (Geophysical Institute at UAF), Jen Arseneau (UAF), Shanil Virani (ASP), Andréa Hughes (NASA), and Lindsay Glesener (University of Minnesota), as well as knowledge holders, students, and scientists.
The Eclipse Ambassadors Off the Path project is supported by NASA under cooperative agreement award number 80NSS22M0007 and is part of NASA’s Science Activation Portfolio. To learn more, visit: www.eclipseambassadors.org.
