@interstellarspacex: Rocket Lab’s Archimedes Vacuum Engine Fires for Full Duration Rocket Lab has successfully completed a full-duration hot-fire test of its vacuum-optimized Archimedes (AVac) engine at NASA’s Stennis Space Center. The test lasted nearly 5.5 minutes, simulating the demands of an actual mission. The AVac engine is designed to power the second stage of Rocket Lab’s upcoming Neutron rocket, featuring an extended nozzle optimized for operation in the vacuum of space. #rocketlab #rocket #test #NASA #SpaceX
