The three engines of the rocket were lit, switched off and re-lit for the landing as planned, but the rocket exploded into a fireball when it returned to the launch pad. It was not immediately clear what went wrong.
SJohn Insprucker, engineer of tempoX, said in the company’s live stream that many of the test flights ‘looked very good’, and engineers were able to collect data to improve the design of the Starship during the flight, which reached about 10 km, or six miles, high.
“We showed the ability to switch the engines to the landing tank, the subsonic entry looked very good and stable,” Insprucker said. “We just have to work on the landing a little bit now.”
The test launch comes after the 160-foot-long rocket prototype crashed on the Texas launch pad over the weekend. According to the Federal Aviation Administration, SpaceX violated an agreement with the public safety agreement that the federal regulators had during a previous test launch.
According to the agency’s statement, the FAA reinstated SpaceX’s permission to launch its rocket prototypes late Monday.
The company did not respond to requests for comment for more than eight months, nor did it respond to requests for comment.
At the root of the rift between SpaceX and the FAA was a test launcher SpaceX launched in December of a prototype known as Starship SN8, one in a series of early prototypes the company built in its efforts to launch a rocket design that the first humans to Mars. Prior to the launch, according to the FAA, SpaceX sought a waiver to exceed the maximum public risk permitted by federal security regulations, but the agency declined the request.
It is not clear whether the FAA would have investigated the company, regardless of whether SN8 landed successfully.
The FAA was already focused on launching its licensing process to make it more “streamlined”. But it is not clear whether the updated procedures, which are expected to take effect in the near future, could quickly help SpaceX loosen the public safety restrictions on the license for its launch.
SpaceX has once again assembled a Starship prototype, SN10. It’s not clear when the company wants to launch it, but over the weekend the company rolled the vehicle with a launch pad next to where the SN9 took off.
