Space Nuclear Propulsion

Dr. Cynthia Null, NASA Technical Fellow for Human Factors, discusses how understanding human capabilities and limitations can help engineers reduce risk and design safer, more successful missions from the start. 

Heather Koehler, NASA Technical Fellow for Flight Mechanics, explains how knowledge at NASA is passed from person to person, program to program.

NASA’s experimental X-59 airplane went supersonic for the first time on June 5, 2026. What's next for the mission that aims to reopen the skies to quiet commercial supersonic flight?

Astronauts aboard the International Space Station depend on life support systems that provide clean air, drinkable water, and a safe, livable environment. These systems are what make long-duration spaceflight not only possible, but comfortable. Today, some of these space station technologies have been adapted for Artemis – specifically, aboard the Orion crew capsule.

Ground teams connect with astronauts aboard the International Space Station to help them carry out research and experiments. Kassandra Stephens, payload communications manager at the Payload Operations Integration Center at Marshall Space Flight Center, works with space station crews to get science done.

A NASA research program collaborates with universities to revolutionize the way we design, build, and operate aircraft. Angela Surgenor, deputy program director of the Transformative Aeronautics Concepts Program, explains.

Before scientists can use those satellite imagery for research, the data must be carefully calibrated to ensure measurements are accurate and consistent over time. Julia Barsi, NASA calibration scientist, explains.

Space nuclear power and propulsion engineering could play a key role in sending robots and humans to deep space, enabling faster and farther journeys.

The “test like you fly” approach is an engineering philosophy that means testing hardware, software, and flight operations as close to reality as possible. Erika Alvarez, deputy director of NASA's Space Systems Department, explains.

So-called “soft skills” like good teamwork and communication can become just as valuable as technical skills to advance exploration.
