Preparations for Next Moonwalk Simulations Underway (and Underwater)
This artist concept shows a NASA-developed small-core jet engine installed in General Electric Aerospace’s CFM RISE jet engine design. The more fuel-efficient small core powers a large open turbofan, which also helps increase efficiency. The effort is part of NASA’s Sustainable Flight National Partnership to help inform the next generation of ultra-efficient airliners.GE Aerospace Hybrid-electric cars have been a staple of the road for many years now.
Soon that same idea of a part-electric-, part-gas-powered engine may find its way into the skies propelling a future jet airliner.
NASA is working in tandem with industry partner GE Aerospace on designing and building just such an engine, one that burns much less fuel by including new components to help electrically power the engine.
In this hybrid jet engine, a fuel-burning core powers the engine and is assisted by electric motors. The motors produce electric power, which is fed back into the engine itself—therefore reducing how much fuel is needed to power the engine in the first place.
It really opens the door for more sustainable aviation even beyond the 2030s.

High Tech Hybrid-Electric
The work is happening as part of NASA’s Hybrid Thermally Efficient Core (HyTEC) project. This work intends to demonstrate this engine concept by the end of 2028 to enable its use on airliners as soon as the 2030s.
It represents a major step forward in jet engine technology.
This jet engine would be the first ever mild hybrid-electric jet engine. A “mild hybrid” engine can be powered partially by electrical machines operating both as motors and generators.
“This will be the first mild hybrid-electric engine and could lead to the first production engine for narrow-body airliners that’s hybrid electric,” said Anthony Nerone, who leads the HyTEC project from NASA’s Glenn Research Center in Cleveland. “It really opens the door for more sustainable aviation even beyond the 2030s.”
The hybrid-electric technology envisioned by NASA and GE Aerospace also could be powered by a new small jet engine core.
A major HyTEC project goal is to design and demonstrate a jet engine that has a smaller core but produces about the same amount of thrust as engines being flown today on single-aisle aircraft.
At the same time, the smaller core technology aims to reduce fuel burn and emissions by an estimated 5 to 10%.

A GE Aerospace Passport engine is being modified with hybrid electric components for testing.
“Today’s jet engines are not really hybrid electric,” Nerone said. “They have generators powering things like lights, radios, TV screens, and that kind of stuff. But not anything that can power the engines.”
The challenge is figuring out the best times to use the electric motors.
“Later this year, we are doing some testing with GE Aerospace to research which phases of flight we can get the most fuel savings,” Nerone said.
Embedded electric motor-generators will optimize engine performance by creating a system that can work with or without energy storage like batteries. This could help accelerate the introduction of hybrid-electric technologies for commercial aviation prior to energy storage solutions being fully matured.
“Together with NASA, GE Aerospace is doing critical research and development that could help make hybrid-electric commercial flight possible,” said Arjan Hegeman, general manager of future of flight technologies at GE Aerospace.
The technologies related to HyTEC are among those GE Aerospace is working to mature and advance under CFM International’s Revolutionary Innovation for Sustainable Engines (RISE) program. CFM is a joint venture between GE Aerospace and Safran Aircraft Engines. CFM RISE, which debuted in 2021, encompasses a suite of technologies including advanced engine architectures and hybrid electric systems aimed at being compatible with 100% Sustainable Aviation Fuel.
HyTEC, part of NASA’s Advanced Air Vehicles Program, is a key area of NASA’s Sustainable Flight National Partnership, which is collaborating with government, industry, and academic partners to address the U.S. goal of net-zero greenhouse gas emissions in aviation by the year 2050.

For 25 years, the Office of STEM Engagement (OSTEM) at NASA’s Johnson Space Center has inspired and provided high school students across the state of Texas with NASA-focused learning experiences through the High School Aerospace Scholars (HAS) program. The OSTEM team celebrated the milestone on Monday, July 29 at Johnson’s Gilruth Center with poster sessions, special presentations, and a networking reception.
Fifty-one students who participated in the 2024 High School Aerospace Scholars program were invited to NASA’s Johnson Space Center in Houston to participate in an on-site experience. NASA/James Blair An authentic STEM learning experience for Texas high school juniors, HAS provides opportunities for students to engage with NASA’s missions and become the next generation of explorers. The year-long program begins in the fall with an online, state-aligned STEM learning experience focused on Earth science, technology, aeronautics, the solar system, the International Space Station, and NASA’s Moon to Mars exploration approach. Students engage in approximately four months of virtual learning through curriculum including interactive lessons, rubric-based activities, and quizzes.
Students who complete the online courses with an overall average of 70% or greater receive an invitation to a five-day virtual summer experience called Moonshot. While actively mentored by NASA scientists and engineers, students work with a team to complete an Artemis-themed Moon to Mars mission and design challenge. The summer session also includes numerous gamified activities and guidance towards pathways to STEM careers.
High School Aerospace Scholars collaborated on an engineering design challenge during their on-site experience at Johnson Space Center. NASA/Bill Stafford The top performing Moonshot teams are then invited to a four-day residential experience at Johnson, with lodging, meals, and transportation provided at no cost to the students. During the on-site session, students participate in NASA facility tours, complete engineering design challenges, and meet with NASA scientists and engineers who offer guidance on STEM careers. At the completion of the program, students can earn up to one full science elective credit for school.
The HAS 25th anniversary celebration coincided with this year’s on-site experience. During the 2023-2024 school year, 798 students participated in the HAS online course, with 359 advancing to the summer Moonshot experience. The top six Moonshot teams (51 students) were invited to Johnson.
High School Aerospace Scholars presented their Moonshot projects to Johnson Space Center team members during a poster session. NASA/James Blair The 51 selected students kicked off the anniversary celebration with a poster session to present their Moonshot projects. Following the session, students heard from Johnson Center Director Vanessa Wyche and Deputy Director Steve Koerner during a fireside chat. Speakers included Pam Melroy, NASA Deputy Administrator; Arturo Sanchez, Johnson External Relations Office Director; Mike Kincaid, NASA OSTEM Associate Administrator; Greg Bonnen, member of the Texas House of Representatives; Brian Freedman, Bay Area Houston Economic Partnership President; and Shelly Tornquist, director of Texas A&M University College of Engineering’s education outreach program, Spark!

NASA/Josh Valcarcel Additionally, the HAS team activated a mobile exhibit at two different on-site locations throughout the week. Over 150 guests stopped by the exhibit, which featured a HAS video montage and the opportunity to touch a lunar sample. Several of the visitors communicated their appreciation for HAS, noting the program has made significant impact on their children’s motivation, school performance, and career paths. Many alumni have gone on to pursue careers within STEM, including nearly 30 HAS participants who have been employed by NASA within the past five years.
2024 High School Aerospace Scholars connected with program alumni and HAS mentors during the Alumni Social held onsite at Johnson Space Center. NASA/Helen Arase Vargas For alumni who wish to continue their experience beyond the year-long program, HAS recently launched a mentorship course, for high school seniors. The course contains modules about leadership and STEM career opportunities and was designed to continue to engage the students as they prepare for the next step in their education or to launch their careers. Alumni also act as an additional layer of support for the junior scholars as they navigate their HAS experience.
HAS is made possible through collaborations among NASA, the State of Texas, Bay Area Houston Economic Partnership, Texas A&M Engineering Experiment Station, Houston Livestock Show and Rodeo, and Rotary National Award for Space Achievement.
Applications will reopen in September for students interested in participating in the 2025 HAS experience.

A Satellite for Optimal Control and Imaging (SOC-i) CubeSat awaits integration at Firefly’s Payload Processing Facility at Vandenberg Space Force Base, California on Thursday, June 6, 2024. SOC-i, along with several other CubeSats, will launch to space on an Alpha rocket during NASA’s Educational Launch of Nanosatellites (ELaNa) 43 mission as part of the agency’s CubeSat Launch Initiative and Firefly’s Venture-Class Launch Services Demonstration 2 contract.NASA NASA is readying for the launch of several small satellites to space, built with the help of students, educators, and researchers from across the country, as part of the agency’s CubeSat Launch Initiative.
The ELaNa 43 (Educational Launch of Nanosatellites 43) mission includes eight CubeSats flying on Firefly Aerospace’s Alpha rocket for its “Noise of Summer” launch from Space Launch Complex-2 at Vandenberg Space Force Base, California. The 30-minute launch window will open at 9 p.m. PDT Wednesday, June 26 (12 a.m. EDT Thursday, June 27).
NASA’s CubeSat Launch Initiative (CSLI) is an ongoing partnership between the agency, educational institutions, and nonprofits, providing a path to space for educational small satellite missions. For the ELaNa 43 mission, each satellite is stored in a CubeSat dispenser on the Firefly rocket and deployed once it reaches sun-synchronous or nearly polar orbit around Earth.
CubeSats are built using standardized units, with one unit, or 1U, measuring about 10 centimeters in length, width, and height. This standardization in size and form allows universities and other researchers to develop cost-effective science investigations and technology demonstrations.

CatSat – University of Arizona, Tucson
CatSat, a 6U CubeSat with a deployable antenna inside a Mylar balloon, will test high-speed communications. Once the CatSat reaches orbit, it will inflate to transmit high-definition Earth photos to ground stations at 50 megabits per second, more than five times faster than typical home internet speeds.
The CatSat design inspiration came to Chris Walker after covering a pot of pudding with plastic wrap. The CatSat principal investigator and professor of Astronomy at University of Arizona noticed the image of an overhanging light bulb created by reflections off the concave plastic wrap on the pot.
“This observation eventually led to the Large Balloon Reflector, an inflatable technology that creates large collecting apertures that weigh a fraction of today’s deployable antennas,” said Walker. The Large Balloon Reflector was an early-stage study developed through NASA’s Innovative Advanced Concepts program.
KUbeSat-1 – University of Kansas, Lawrence
The KUbeSat-1, a 3U CubeSat, will use a new method to measure the energy and type of primary cosmic rays hitting the Earth, which is traditionally done on Earth. The second payload, the High-Altitude Calibration will measure very high frequency signals generated by cosmic interactions with the atmosphere. KUbeSat-1 is Kansas’ first small satellite to launch under NASA’s CSLI.
MESAT-1 – University of Maine, Orono
MESAT-1, a 3U CubeSat, will study local temperatures across city and rural areas to determine phytoplankton concentration in bodies of water to help predict algal blooms. MESAT-1 is Maine’s first small satellite to launch under NASA’s CSLI.
R5-S4, R5-S2-2.0 - NASA’s Johnson Space Center
R5-S4 and R5-S2-2.0, both 6U CubeSats, will be the first R5 spacecraft launched to orbit to test a new, lean spacecraft build. The team will monitor how each part of the spacecraft performs, including the computer, software, radio, propulsion system, sensors, and cameras in low Earth orbit.
NASA and Firefly Aerospace engineers review the integration plan for the agency’s CubeSat R5 Spacecraft 4 (R5-S4) at Firefly Aerospace’s Payload Processing Facility at Vandenberg Space Force Base, California on Wednesday, April 24, 2024.NASA/Jacob Nunez-Kearny “In the near term, R5 hopes to demonstrate new processes that allows for faster and cheaper development of high-performance CubeSats,” said Sam Pedrotty, R5 project manager at NASA’s Johnson Space Center in Houston. “The cost and schedule improvements will allow R5 to provide higher-risk ride options to low-Technology Readiness Levels payloads so more can be demonstrated on-orbit.”
Serenity – Teachers in Space
Serenity, a 3U CubeSat equipped with data sensors and a camera, will communicate with students on Earth through amateur radio signals and send back images. Teachers in Space launches satellites as educational experiments to stimulate interest in space science, technology, engineering, and math among students in North America.
SOC-i – University of Washington, Seattle
Satellite for Optimal Control and Imaging (SOC-i), a 2U CubeSat, is a technology demonstration mission of attitude control technology used to maintain its orientation in relation to the Earth, Sun, or other body. This mission will test an algorithm to support autonomous operations with constrained attitude guidance maneuvers computed in real-time aboard the spacecraft. SOC-i will autonomously rotate its camera to capture images.
TechEdSat-11 (TES-11) – NASA’s Ames Research Center, California’s Silicon Valley
TES-11, a 6U CubeSat, is a collaborative effort between NASA researchers and students to evaluate technologies for use in small satellites. It’s part of ongoing experiments to evaluate new technologies in communications, a radiation sensor suite, and experimental solar panels, as well as to find ways to reduce the time to de-orbit.
