Video: Relativity’s Full Duration Mission Duty Cycle Hot Fire

Video Caption: Relativity successfully completed our Aeon 1 engine Mission Duty Cycle (MDC) test at NASA’s Stennis Space Center in Mississippi. Our fully integrated Aeon 1 engine hotfired running at full power for 187 seconds, meeting the full duration required for the launch of our Terran 1 first stage.

A Mission Duty Cycle test is a pinnacle milestone in engine development, as it proves that all key engine components (turbopumps, injector, chamber, igniters, etc.) can operate in a flight-like configuration.

Relativity’s speed of execution, from first integrated engine testing to successful MDC in 56 days, is a tremendous accomplishment. This significant milestone validates the advantages of our 3D printing technology and best-in-class team, as we march forward towards first launch!
