SpaceX’s Falcon 9 rocket is ready to fly back into space.

The U.S. Federal Aviation Administration (FAA) said on Thursday, July 25, that it had cleared SpaceX’s Falcon 9 rocket to return to space after the FAA issued a temporary grounding. That’s because the rocket’s second stage couldn’t be fitted with an engine. The rocket lost directional control, so Starlink satellites can only be launched into low orbits, very close to Earth. All of the satellites returned to burn up and destroy Earth’s atmosphere. It’s the first failure of a Falcon 9 rocket in seven years.

The FAA said that all malfunctions or defects that occurred during the July 11 launch of the Falcon 9 were investigated and found not to be a public safety issue, and therefore SpaceX allowed the Falcon 9 rocket to relaunch for space missions. In the meantime, the investigation will continue according to the following steps.

SpaceX has announced a new day for the Starlink 10-4 mission, where nothing will go wrong. The Polaris Dawn mission, which will send four private astronauts into orbit in new spacesuits, is expected to continue, with Jared Isaacson at the helm.

On Thursday, SpaceX posted on its website that the company had filed a report with the FAA about the Falcon 9 launch failure and that it had been able to determine the cause, as well as fixes that would not cause problems in the future. The company said the cause was a crack in a pressure sensor cable. This caused a liquid oxygen leak. This caused a section of the engine to overcool, which then affected the liquid fuel delivery equipment. This made it difficult to start the engine and damaged the engine hardware. This caused the upper section of the rocket to lose control of its orientation.

In the new Falcon 9 launch, SpaceX will avoid the problem by disconnecting the faulty sensor cable and sensor from the rocket’s second-stage engine, a sensor that flight safety systems don’t actually use. It can be repaired using another sensor available in the engine.

Falcon 9 is the only American rocket. It is certified to send NASA astronauts to the International Space Station. There will be a mission to send astronauts aboard the Crew Dragon spacecraft in August of next year.
