Relativity Space(@relativityspace):September was a big month for test operations across our sites. 📍 NASA Stennis, MS Stage 2 completed its first wet dress rehearsal! The team put the stage through flight-like propellant loading, COPV fills, engine chill operations, and a simulated stage 1 ascent timeline, building toward its first integrated hot fire. 📍 Long Beach, CA All 13 Aeon R engines are installed on the thrust structure and are moving through integrated gimbal testing, validating their ability to pivot precisely to steer and stabilize the vehicle during flight.
