NASA Completes Nuclear Propulsion Cold-Flow Test Campaign
NASA has completed its cold-flow test campaign of a nuclear propulsion technology that could power future missions to the moon and Mars.
The space agency said Tuesday that it conducted over 100 tests on the flight-like engineering development unit built by BWX Technologies.
What Did NASA Discover From Its Space Nuclear Propulsion Test?
The cold flow test, carried out at the NASA Marshall Space Flight Center in Huntsville, Alabama, over several months in 2025, simulated operational fluid-dynamic responses of the engineering development unit.
The researchers also validated that the reactor design is not prone to destructive shaking or oscillations typically caused by moving fluids.
“This test series generated some of the most detailed flow responses for a flight-like space reactor design in more than 50 years and is a key stepping stone toward developing a flight-capable system,” shared Jason Turpin, manager of the Space Nuclear Propulsion Office at NASA Marshall. “Each milestone brings us closer to expanding what’s possible for the future of human spaceflight, exploration and science.”
Why Is NASA Developing Space Nuclear Propulsion?
Nuclear propulsion systems eliminate the need for solar power, allowing spacecraft to travel farther away from the sun, according to NASA. Moreover, the propulsion technology can also reduce travel times and increase a spacecraft’s science payload capacity.
“By shortening travel times and expanding mission capabilities, this technology will lay the foundation to explore farther into our solar system than ever before,” commented Greg Stover, acting associate administrator of the Space Technology Mission Directorate at NASA headquarters in Washington, D.C.
President Donald Trump on Tuesday signed a consolidated appropriations measure into law to end a partial government shutdown and fund the Department of War and other federal agencies through the end of September, according to a White House notice. The signing came shortly after the House approved the measure. Breaking Defense reported that the lower chamber voted 217-214 on Tuesday to pass the funding package, which includes a short-term funding measure for the Department of Homeland Security. The Senate had sent the package of five fiscal year appropriations bills to the House after approving the measure Friday by a 71-29
The Senate has confirmed Maj. Gen. Luke Cropsey for promotion to lieutenant general, elevating him to a three-star role as he becomes the military deputy in the Office of the Assistant Secretary of the Air Force for Acquisition, Technology and Logistics. The Potomac Officers Club’s 2026 Air and Space Summit will bring together leaders from the U.S. Air Force, U.S. Space Force and industry to discuss current priorities across the air and space domains. Taking place July 30, the event will feature keynotes, panel discussions and opportunities to connect with peers while exploring emerging challenges and technologies shaping the future
The Department of War has selected 25 companies to compete in the initial phase of an acquisition reform initiative aimed at rapidly fielding low-cost, small unmanned aerial systems designed to perform one-way attack missions. DOW said the selected vendors will participate in the Drone Dominance Program’s initial evaluation phase, known as the Gauntlet, which will kick off on Feb. 18 at Fort Benning in Georgia. The Pentagon’s Drone Dominance Program highlights how rapidly evolving acquisition efforts continue to shape the defense landscape. These broader trends in air and space operations will bring government and industry leaders together at the Potomac
