Astrobotic Completes Record 300-Second Burn with Chakram Detonation Engine
Astrobotic has successfully conducted a 300-second burn of its Chakram rotating detonation rocket engine (RDRE), the longest for this technology. This advancement could significantly enhance payload capacities for lunar missions and orbital transfers, addressing efficiency gaps in traditional rocket engines.

Astrobotic's Chakram RDRE achieved a continuous 300-second burn during hot-fire tests at NASA's Marshall Space Flight Center, the longest duration for this type of engine. The engine's design, based on pressure gain combustion, is projected to improve specific impulse by up to 15%, allowing for greater efficiency in lunar landers and orbital transfer vehicles.
The tests demonstrated 4,000 pounds of thrust with no damage to hardware, thanks to integrated PermiAM technology for thermal management. The development is backed by NASA funding and aims to enhance payload capacity for lunar deliveries. Future phases will focus on regenerative cooling and flight qualifications for the cislunar economy.
