According to CCTV news, on June 2nd local time, the National Aeronautics and Space Administration and Boeing announced that their team plans to attempt the launch of an interstellar airliner again on June 5th for a manned test flight mission.
On June 1st, the first manned test flight mission of Boeing's Starplane spacecraft was cancelled due to technical malfunctions. NASA stated that its team evaluated the ground support equipment on the launch pad that had issues during the countdown period and found a problem with the ground power supply inside one of the chassis. NASA stated that the chassis equipped with a faulty ground power unit has been removed and replaced with a spare chassis.
The interstellar aircraft was originally scheduled to conduct its first manned test flight on May 6th Eastern Time in the United States, but it has been delayed multiple times due to technical reasons.
