Rotating detonation rocket engines (RDREs) work differently from conventional designs. Typical rocket engines rely on a steady, controlled process of chemical propellant ignition

NASA fired up RS-25 engine No. 20001 at the Fred Haise Test Stand at NASA’s Stennis Space Center at Bay St. Louis, Mississippi. The test lasted about "eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during a launch of an SLS (Space Launch System) rocket on Artemis missions to the Moon,

Rotating detonation rocket engines work differently than traditional rockets to maximize thrust while using less fuel—an advantage that could help spacecraft explore farther in the solar system
