On Saturday, June 1, NASA and Boeing are scheduled to test the first flight of the Starliner CST-100 space capsule with astronauts. The first group of astronauts was sent to the International Space Station (ISS) aboard ULA's Atlas V rocket, lifting off from the SLC-41 launch pad at Cape Canaveral Air Force Station, Florida, at 10:34 p.m. ET (in Thailand, Sunday 9:34 AM) Unfortunately, there was a last-minute interruption during the time countdown, so the mission had to be put on hold for the time being.
The crewed flight test (CFT) mission was with NASA astronauts Butch Wilmore and Sonny Williams sitting in a Starliner space capsule when the mission crashed. A ground-based computer glitch stopped the countdown about 3 minutes and 50 seconds before launch. As a result, the mission had to be postponed.
ULA CEO Torey Bruno said the launch sequence card on one of the three replacement ground control computers was running slower than the other two at the four-minute countdown. There was an interruption in operation causing the automatic missile launch system to suspend. But the team was unable to enter and change guards near the launch pad. You must wait until the rocket runs out of fuel first, which takes at least 2-3 hours, then check the computer and cards that need to be replaced. If the task is completed in time, it will be postponed to June 2, but if there is anything more than that, it may take a long time. Therefore, we would like to book the launch date for the mission on June 5 and 6.
NASA later revealed that it would not attempt to launch the mission on June 2 to give the team more time to study the problem. The schedule will be updated again on June 2.
