Swiss Students Test 20,000-Detonation-Per-Second Rotating Rocket Engine

A team of ETH Zurich students from the ARIS Pegasus project tested a rotating detonation rocket engine powered by propane and liquid oxygen, achieving stable detonation waves at up to 20,000 per second in a nighttime test at Dübendorf Air Base. The milestone underscores growing international interest in rotating detonation propulsion, which could improve fuel efficiency and payload capacity for future space missions, though it demands advanced materials and ultra-fast fuel injection. The project highlights collaborative, iterative student research and places Switzerland among a small group pursuing RDRE demonstrations.

Astrobotic’s Chakram RDRE Delivers Spiraling Exhaust and a Record-Setting Burn

Astrobotic unveils its Chakram rotating detonation rocket engine (RDRE), showing three detonation waves that produce a spiraling exhaust flame and delivering over 4,000 pounds of thrust in tests at NASA's Marshall Space Flight Center, including a 300-second burn believed to be a new RDRE record. The results hint at potential uses from lunar landers to in-space propulsion.

Astrobotic's Chakram RDRE Achieves 300-Second Burn, Pushing Propulsion Toward Flight

Astrobotic’s Chakram rotating detonation rocket engine achieved a 300-second continuous burn at NASA’s Marshall Space Flight Center, with two prototypes delivering sustained operation, stable detonation, and about 4,000+ pounds of thrust per engine, marking a key step from experimental tests toward flight-ready propulsion for lunar landers and cislunar missions.

Astrobotic notches record-setting Chakram RDRE burn in NASA test campaign

Astrobotic completed a series of hot-fire tests of its Chakram rotating detonation rocket engine at NASA's Marshall Space Flight Center, firing two RDRE prototypes for more than 470 seconds in total and logging a continuous 300-second burn—the longest RDRE test to date. The tests demonstrated stable, thermally steady operation and are expected to inform throttle control, cooling, and mass reduction as the company advances toward flight-ready lunar landers and cislunar transfer vehicles.

Astrobotic’s Chakram RDRE Delivers 4,000+ Lbf Thrust in NASA Hot-Fire Demo

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.

NASA Achieves Success with 3D-Printed Rotating Detonation Rocket Engine Test

NASA's Marshall Space Flight Center has successfully tested a 3D-printed Rotating Detonation Rocket Engine (RDRE) for over four minutes, generating more than 5,800 pounds of thrust. The test aimed to understand how to scale the combustor to different thrust classes, supporting various engine systems and missions, including landers and deep space burns. The RDRE offers improved design efficiency, enabling the transportation of more mass and payload further into deep space, aligning with NASA's Moon to Mars vision. NASA's Glenn Research Center and Venus Aerospace are collaborating to scale the technology for higher performance.
