On June 19th, according to US media reports, on June 18th local time, the National Aeronautics and Space Administration (NASA) of the United States announced that it will once again postpone the return of the Boeing interstellar spacecraft to Earth until the 26th. This is the third time that the spacecraft has postponed its return time.
According to reports, NASA and Boeing hope to have more time to study helium leaks and issues with several thrusters malfunctioning during flight. In addition, the US space website stated that the spacewalk arrangement of the International Space Station was also one of the reasons for the delayed return of the spacecraft.
According to previous reports, the first manned test flight of the interstellar aircraft took off on June 5th with two American astronauts and arrived at the International Space Station on June 6th. It was originally scheduled to return to Earth on the 14th. But the return time was later postponed to the 18th and later to the 22nd.
