Hyperbola-3 first-stage auxiliary propulsion system passes full-system test
58 FOMOThe cold-gas auxiliary propulsion system completed a full-system test under conditions matching the planned flight configuration and sequence. The system combines attitude control for first-stage return and landing with propellant settling during the recovery phase. The test verified coordinated operation, commanded engine starts and shutdowns, and component compatibility. The company said the system was ready for delivery to final vehicle assembly.
Why it matters
The test validates a key recovery subsystem rather than the primary ascent propulsion system. Its successful qualification is important for safe booster return and post-flight handling.
