Interstellar Glory completed a cryogenic static test of the Hyperbola-3 second-stage common-bulkhead propellant tank. The tank measures 4.2 metres in diameter and approximately 11 metres in length. Testing covered pressure, axial compression, bending and concentrated-load conditions across ground and flight operations, alongside pressurisation and feed-system validation.
