TL;DR

Astrobotic tested its Chakram rotating detonation rocket engine at NASA’s Marshall Space Flight Center, firing two prototypes to more than 4,000 pounds of thrust per engine for a combined 470 seconds of burn time across eight hot-fire tests, with no damage observed. The RDRE uses detonation shockwaves in a circular channel to boost efficiency and has potential for lunar landers and deep-space propulsion, supported by NASA SBIR awards and a Space Act Agreement; similar RDRE work is underway by Venus Aerospace and NASA.
