The space agency NASA and Boeing announced that the launch of Boeing's Starliner crew capsule has been postponed again.

According to Amac News: NASA has said that they were given four more days to evaluate the helium leak before launching the two astronauts.
The Starliner flight from Florida was delayed several times in May, and was last scheduled for May 21.
Apart from the helium leak, NASA said a technical problem with its Atlas 5 rocket had caused the earlier delay.
The program is several years behind schedule and over $1.5 billion in funding.
Boeing has been developing Starliner for more than a decade to provide NASA with a second American spacecraft capable of carrying astronauts to the International Space Station.
SpaceX's Dragon crew capsule, built under the same NASA program, sent astronauts into space for the first time in 2020.
