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.

NASA/Jonny Kim The Soyuz MS-26 spacecraft is pictured backing away from the International Space Station shortly after undocking on April 19, 2025. Three hours later, the spacecraft landed in Kazakhstan, returning astronaut Don Pettit and cosmonauts Alexey Ovchinin and Ivan Vagner to Earth.
While aboard the International Space Station, Pettit conducted hundreds of hours of scientific investigations, including research to enhance on-orbit metal 3D printing capabilities, advance water sanitization technologies, explore plant growth under varying water conditions, and investigate fire behavior in microgravity, all contributing to future space missions.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
As associate administrator for NASA’s Space Operations Mission Directorate Ken Bowersox puts it, “nothing happens without communications.”
And effective communications require the use of radio waves.
None of NASA’s exciting science and engineering endeavors would be possible without the use of radio waves to send data, communications, and commands between researchers or flight controllers and their flight platforms or instruments.
Reflecting on his time as a pilot, commander, and mission specialist during the Space Shuttle Program, Bowersox says, “If you’re not there physically, you can’t be a part of the team. But if you’re getting the data, whether it’s video, telemetry data with states of switches, or individual parameters on temperatures or pressures, then you can act on it and provide information to the spacecraft team so they can do the right thing in their operation.”
These vital data and communications functions, as well as the gathering of valuable scientific data through remote sensing applications, all use radio frequencies (RF) within the electromagnetic spectrum. NASA centers and facilities also use the RF spectrum to support their everyday operations, including the walkie-talkies used by security guards, air traffic control systems around airfields, and even office Wi-Fi routers and wireless keyboards.

All of NASA’s uses of the RF spectrum are shared, with different radio services supporting other kinds of uses. Service allocation is a fundamental concept in spectrum regulation and defines how the spectrum is shared between different types of applications. A service allocation defines ranges, or bands, of radio frequencies that can be used by a particular type of radio service. For example, a television broadcasting satellite operates in frequency bands allocated to the broadcasting satellite service, terrestrial cellular services operate in bands allocated for the mobile service, and the communications antennas on the International Space Station (ISS) operate in bands allocated to space operations service.
However, an allocation is not a license to operate — it does not authorize a specific system or operator to use particular frequencies. Such authority is granted through domestic and international regulatory processes.
Most frequency bands of the RF spectrum are shared, and each frequency band typically has two or more radio services allocated to it. Careful spectrum regulation, planning, and management aim to identify mutually compatible services to share frequency bands while limiting its negative impacts.
NASA’s Most Notable Spectrum Uses
Many of NASA’s most notable uses of spectrum rely on the following service allocations:
Earth exploration-satellite service Space research service Space operations service Inter-satellite service Note that allocations in the Earth exploration-satellite service and the space research service are designated either for communications links in the Earth-to-space, space-to-Earth, or space-to-space directions or designated for active or passive sensing of Earth or celestial objects (respectively) to differentiate the types of uses within the service and afford the requisite protections.
