See Astrobotic pull off a major test of its ‘ring of fire’ rocket engine
Astrobotic successfully tested its rotating detonation rocket engines (RDREs) for over 470 seconds, including a 300-second continuous burn, at NASA's Marshall Space Flight Center. The test is a significant step towards developing more efficient rocket technology for future lunar missions.
Private space company Astrobotic recently conducted a successful test of its rotating detonation rocket engines (RDREs), firing two engines for over 470 seconds. The test, which included a 300-second continuous burn, took place at NASA's Marshall Space Flight Center. Astrobotic's RDREs, called Chakram engines, use liquid fuel and produce thrust through a supersonic shock wave, resulting in a more powerful explosion. The company aims to use this technology in its Griffin lunar landers, with the first Griffin mission to the moon scheduled to launch no earlier than July using a SpaceX Falcon Heavy rocket. The Chakram engines generated over 4,000 pounds of thrust each, but require further testing before being launch-ready. Astrobotic is not the only company developing RDREs, with other companies like Venus Aerospace and Japan Aerospace Exploration Agency (JAXA) also working on similar technology.
