SpaceX and NASA say they have resolved Recently found in the Falcon 9 rocket It also plans to send four astronauts to the International Space Station on the “Chenglong” spacecraft on November 14.

On October 2, the planned U.S. Space Force GPS satellite launched by the Falcon 9 was automatically suspended a few seconds before the launch. Subsequent investigations revealed that two of the rocket’s nine Merlin engines tried to start as soon as possible, which triggered an automatic suspension.

In a call with reporters on Wednesday, Hans Koenigsmann, SpaceX’s vice president of construction and flight reliability, explained that the suspension prevented a “hard start”, which could cause some damage to the engine. .

The engine was removed from the rocket for testing, and it was found that the tiny safety valve line was blocked. Obviously, during the cleaning process, the red mask lacquer is similar to nail polish. It was removed and washed into a small hole about 16 inches (1.57 mm), then hardened and blocked the line.

Koenigsman said that SpaceX “discovered the same trend in the engines used for the Crew-1 launch and the engines scheduled to launch NASA’s Sentinel-6 Michael Freilich satellite on November 10” to monitor global sea levels.

The suspicious engine has been replaced, and NASA and SpaceX now indicate that they hope to prepare for launch on November 14.

The “Crew 1” mission is the first flight to the International Space Station since the “Demonstration 1” flight of “Crew Dragon” brought NASA astronauts Doug Hurley and Bob Bacon there. Since the end of the space shuttle program, that landmark flight was the first crew flight in the United States.

When Crew-1 transports NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker and Soichi Noguchi of Japan Aeronautics and Space Administration to the ISS, it will expand the crew of the space station to seven, allowing more research to be conducted. On Tracks.

“Crew 1” is scheduled to be launched from the Kennedy Space Center in Florida at 4:49 pm Pacific time (7:49 pm Eastern time) on November 14.
