Engineers recreated the diffuser failure on the bottom throughout the investigation, after which redesigned the half to raised direct pressurized fuel into the primary gas tank. This may also “considerably lower” pressure on the diffuser construction, SpaceX mentioned.
The FAA, charged with guaranteeing industrial rocket launches do not endanger public security, signed off on the investigation and gave the inexperienced gentle for SpaceX to fly Starship once more when it’s prepared.
“SpaceX can now proceed with Starship Flight 10 launch operations underneath its present license,” the FAA mentioned.
“The upcoming flight will proceed to increase the working envelope on the Tremendous Heavy booster, with a number of touchdown burn exams deliberate,” SpaceX mentioned in an replace posted to its web site Friday. “It should additionally goal related goals as earlier missions, together with Starship’s first payload deployment and a number of reentry experiments geared in direction of returning the higher stage to the launch website for catch.”

Within the aftermath of the take a look at flight in Could, SpaceX hoped to fly Starship once more by late June or early July. However one other accident June 18, this time on the bottom, delayed this system one other couple of months. The Starship automobile SpaceX assigned to the subsequent flight, designated Ship 36, exploded on a take a look at stand in Texas as groups stuffed it with cryogenic propellants for an engine test-firing.
The accident destroyed the ship and broken the take a look at website, prompting SpaceX to retrofit the only energetic Starship launch pad to help testing of the subsequent ship in line—Ship 37. These exams included a short firing of all six of the ship’s Raptor engines August 1.
After Ship 37’s closing spin prime take a look at Wednesday, employees transported the rocket again to a hangar for analysis, and crews instantly started working transitioning the launch pad again to its regular configuration to host a full Tremendous Heavy/Starship stack.
SpaceX mentioned the explosion on the take a look at stand in June was possible brought on by harm to a high-pressure nitrogen storage tank inside Starship’s payload bay part. This tank, known as a composite overwrapped stress vessel, or COPV, violently ruptured and led to the ship’s fiery demise. SpaceX mentioned COPVs on upcoming flights will function at decrease pressures, and managers ordered further inspections on COPVs to search for harm, extra proof testing, extra stringent acceptance standards, and a {hardware} change to handle the issue.
