Boeing announced that the launch of the first manned CST-100 Starliner to the International Space Station has been postponed indefinitely.

The decision was taken together with the US National Aeronautics and Space Administration (NASA). It was previously reported that developers were busy fixing a “minor helium leak detected in the service module” of the CST-100 Starliner spacecraft ahead of the spacecraft’s launch on May 21.

The Crew Flight Test mission was originally scheduled to take place on Monday, May 6, but the mission team aborted the launch about two hours before liftoff after noticing that the oxygen release valve in the Atlas V’s upper stage, called the Centaur, was rapidly opening. closing. This repetitive action was described by team members as “humming”.

The planned launch was postponed to May 10, but the launch was postponed for another week after ULA determined that a valve needed to be replaced, a process that required the Starliner-Atlas V to be returned to the workshop.
