Summary

Story summary

Astrobotic tested its Chakram rotating-detonation rocket engine at NASA’s Marshall Space Flight Center.
Two prototypes delivered a record 300-second continuous burn within a 470-second test, generating over 4,000 pounds-force of thrust without damage.
Funding comprised two NASA SBIR awards, a Space Act Agreement and $5 million in NASA and military contracts.
Astrobotic will use Chakram on Griffin lunar landers and suborbital vehicles to improve cooling, throttling and reduce mass.
