NASA and Boeing have announced a new launch date for the CST-100 Starliner spacecraft. The spacecraft is now scheduled to go into space on June 5th.

The previous attempt to launch the Starliner was scheduled for June 1. However, just 3 minutes and 50 seconds before the Atlas V rocket was supposed to break away from the launch pad, automation interrupted the pre-launch countdown.

Subsequent investigation revealed that the reason for the cancellation of the launch was a problematic power supply unit, which was used in one of the ground computers responsible for controlling the fuel valves on the Centaur upper stage. Engineers have already replaced the faulty unit with a spare one.

The next attempt to send a Starliner into space is scheduled for June 5. If there are no new problems, the Atlas V rocket will leave the launch pad at 10:52 a.m. EDT (1452 GMT). According to forecasters, there is a 90% probability that the weather at this moment will be favorable for the launch. The reserve launch window will open on June 6 at 10:29 a.m.
