NASA/Charles Beason Students from the University of Massachusetts Amherst team carry their high-powered rocket toward the launch pad at NASA’s 2025 Student Launch launch day competition in Toney, Alabama, on April 4, 2025. More than 980 middle school, high school, and college students from across the nation launched more than 40 high-powered amateur rockets just north of NASA’s Marshall Space Flight Center in Huntsville, Alabama. This year marked the 25th anniversary of the competition.
To compete, students follow the NASA engineering design lifecycle by going through a series of reviews for nine months leading up to launch day. Each year, a payload challenge is issued to the university teams, and this year’s task focused on communication. Teams were required to have “reports” from STEMnauts, non-living objects inside their rocket, that had to relay real-time data to the student team’s mission control. This Artemis Student Challenge took inspiration from the agency’s Artemis missions, where NASA will send astronauts to explore the Moon for scientific discovery, economic benefit, and to build the foundation for the first crewed missions to Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
When most people think of NASA, they picture rockets, astronauts, and the Moon. But behind the scenes, a group of inventors is quietly rewriting the rules of what’s possible — on Earth, in orbit, and beyond. Their groundbreaking inventions eventually become technology available for industry, helping to shape new products and services that improve life around the globe. For their contributions to NASA technology, we welcome four new inductees into the 2024-2025 NASA Inventors Hall of Fame
A robot for space and the workplace
Myron (Ron) Diftler led the team behind Robonaut 2 (R2), a humanoid robot developed with General Motors. The goal was to create a robot that could help humans both in space and on the factory floor. The R2 robot became the first humanoid robot in space aboard the International Space Station, and part of its technology was licensed for use on Earth, leading to a grip-strengthening robotic glove to help humans with strenuous, repetitive tasks. From factories to space exploration, Diftler’s work has real-world impact.
Some of the toughest electronic chips on and off Earth
Technology developed to one day explore the surface of Venus has to be tough enough to survive the planet where temperatures hit 860°F and the atmosphere is akin to battery acid. Philip Neudeck’s silicon carbide integrated circuits don’t just work — they ran for over 60 days in simulated Venus-like conditions. On Earth, these chips can boost efficiency in wireless communication systems, help make drilling for oil safer, and enable more practical electric vehicles.
From developing harder chip materials to unlocking new planetary missions, Neudeck is proving that the future of electronics isn’t just about speed — it’s about survival.
Hydrogen sensors that could go the distance on other worlds
Gary Hunter helped develop a hydrogen sensor so advanced it’s being considered for a future mission to Titan, Saturn’s icy moon. These and a range of other sensors he’s helped developed have applications that go beyond space exploration, such as factory floors here on Earth.
With new missions on the horizon and smarter sensors in development, Hunter is still pushing the boundaries of what NASA technology can do. Whether it’s Titan, the surface of Venus, or somewhere we haven’t dreamed of yet, this work could help shape the way to get there.
Advanced materials research to make travel safer
Advanced materials, such as foams and composites, are key to unlocking the next generation of manufacturing. From space exploration to industry, Erik Weiser spent years contributing his expertise to the development of polymers, ceramics, metals, nanomaterials, and more. He is named on more than 20 patents. During this time, he provided his foam expertise to the Space Shuttle Columbia accident investigation, the Shuttle Discovery Return-to-Flight Investigation and numerous teams geared toward improving the safety of the shuttle.
Today, Weiser serves as director of the Facilities and Real Estate Division at NASA Headquarters, overseeing the foundation of NASA’s missions. Whether it’s advancing research or optimizing real estate across the agency, he’s helping launch the future, one facility at a time.

One half of NASA’s nearly complete Nancy Grace Roman Space Telescope just passed a lengthy test to ensure it will function properly in the space environment. This milestone keeps Roman well on track for its target launch by May 2027, with the team aiming for as early as fall 2026.

Credit: NASA/Sydney Rohde “This milestone tees us up to attach the flight solar array sun shield to the outer barrel assembly, and deployable aperture cover, which we’ll begin this month,” said Jack Marshall, who leads integration and testing for these elements at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Then we’ll complete remaining environmental tests for the flight assembly before moving on to connect Roman’s two major assemblies and run the full observatory through testing, and then we’ll be ready to launch!”
Prior to this thermal testing, technicians integrated Roman’s deployable aperture cover, a visor-like sunshade, to the outer barrel assembly, which will house the telescope and instruments, in January, then added test solar panels in March. They moved this whole structure into the Space Environment Simulator test chamber at NASA Goddard in April.
There, it was subjected to the hot and cold temperatures it will experience in space. Next, technicians will join Roman’s flight solar panels to the outer barrel assembly and sunshade. Then the structure will undergo a suite of assessments, including a shake test to ensure it can withstand the vibrations experienced during launch.
This photo captures the installation of the test solar panels for NASA’s Nancy Grace Roman Space Telescope, which took place in March. One panel is lifted in the center of the frame on its way to being attached to the outer barrel assembly at right. The deployable aperture cover is stowed on the front of the outer barrel assembly, and the other half of the observatory — the spacecraft and integrated payload assembly, which consists of the telescope, instrument carrier, and two instruments — appears at the left of the photo.Credit: NASA/Jolearra Tshiteya Meanwhile, Roman’s other major portion — the spacecraft and integrated payload assembly, which consists of the telescope, instrument carrier, and two instruments — will undergo its own shake test, along with additional assessments. Technicians will install the lower instrument sun shade and put this half of the observatory through a thermal vacuum test in the Space Environment Simulator.
“The test verifies the instruments will remain at stable operating temperatures even while the Sun bakes one side of the observatory and the other is exposed to freezing conditions — all in a vacuum, where heat doesn’t flow as readily as it does through air,” said Jeremy Perkins, an astrophysicist serving as Roman’s observatory integration and test scientist at NASA Goddard. Keeping the instrument temperatures stable ensures their readings will be precise and reliable.
Technicians are on track to connect Roman’s two major parts in November, resulting in a complete observatory by the end of the year. Following final tests, Roman is expected to ship to the launch site at NASA’s Kennedy Space Center in Florida for launch preparations in summer 2026. Roman remains on schedule for launch by May 2027, with the team aiming for launch as early as fall 2026.

NASA Selects Winners of the 2024-2025 Power to Explore Challenge
Ten-year-old, Terry Xu of Arcadia, California; 14-year-old, Maggie Hou of Snohomish, Washington; and 17-year-old, Kairat Otorov of Trumbull, Connecticut, winners of the 2024-2025 Power to Explore Student Writing Challenge. NASA/David Lam, Binbin Zheng, The Herald/Olivia Vanni, Meerim Otorova NASA has chosen three winners out of nine finalists in the fourth annual Power to Explore Challenge, a national writing competition designed to teach K-12 students about the enabling power of radioisotopes for space exploration.
“Congratulations to the amazing champions and all of the participants!
Carl Sandifer II
Program Manager, NASA’s Radioisotope Power Systems Program
The essay competition asked students to learn about NASA’s radioisotope power systems (RPS), likened to “nuclear batteries,” which the agency has used discover “moonquakes” on Earth’s Moon and study some of the most extreme of the more than 891 moons in the solar system. In 275 words or less, students dreamed up a unique exploration mission of one of these moons and described their own power to achieve their mission goals.
“I’m so impressed by the creativity and knowledge of our Power to Explore winners,” said Carl Sandifer II, program manager of the Radioisotope Power Systems Program at NASA’s Glenn Research Center in Cleveland.
Entries were split into three groups based on grade level, and a winner was chosen from each. The three winners, each accompanied by a guardian, are invited to NASA’s Glenn Research Center in Cleveland for a VIP tour of its world-class research facilities this summer.
The winners are:
Terry Xu, Arcadia, California, kindergarten through fourth grade Maggie Hou, Snohomish, Washington, fifth through eighth grade Kairat Otorov, Trumbull, Connecticut, ninth through 12th grade “Congratulations to the amazing champions and all of the participants! Your “super powers” inspire me and make me even more optimistic about the future of America’s leadership in space,” Sandifer said.
The Power to Explore Challenge offered students the opportunity to learn about space power, celebrate their own strengths, and interact with NASA’s diverse workforce. This year’s contest received nearly 2,051 submitted entries from all 50 states, U.S. territories, and the Department of Defense Education Activity overseas.
Every student who submitted an entry received a digital certificate and an invitation to the Power Up virtual event held on March 21. There, NASA announced the 45 national semifinalists, and students learned about what powers the NASA workforce.
Additionally, the national semifinalists received a NASA RPS prize pack.
NASA announced three finalists in each age group (nine total) on April 23. Finalists were invited to discuss their mission concepts with a NASA scientist or engineer during an exclusive virtual event.
The challenge is funded by the Radioisotope Power Systems Program Office in NASA’s Science Mission Directorate and administered by Future Engineers under a Small Business Innovation Research phase III contract. This task is managed by the NASA Tournament Lab, a part of the Prizes, Challenges, and Crowdsourcing Program in NASA’s Space Technology Mission Directorate.
