The FAA said on Friday it had closed an investigation into the April 20 explosion of a Starship rocket and ordered 63 corrective actions Musk's company must take to prevent future incidents.
"Congrats to SpaceX for completing & documented the 57 items required by the FAA for Flight 2 of Starship! Worth noting that 6 of the 63 items refer to later flights," Musk posted on his X profile.
He also shared a graphic table showing what corrective measures were completed. The items include, in particular, a new sealing design for certain areas of the booster, improvements to the safety system and redesigning of the fire suppression system.
The second Starship test flight is expected to take place once the FAA reviews the completed items.
On April 20, the world's biggest rocket exploded just minutes after taking off for the first time. As a result of the blast, a launch pad was destroyed, sending debris and ash over a large area, including adjacent lands that provide habitat for endangered species.
