(AFP / VOZ MEDIA) The return of Boeing's Starliner spacecraft to Earth from the International Space Station (ISS), originally scheduled for June 26, was postponed again, NASA announced Friday night:

This new postponement will allow more time to examine the propellant problems and helium leaks that caused the first delay, NASA added.

The first manned Starliner mission to the ISS, with two astronauts on board, was supposed to last about eight days, but is now extended to an undetermined date.

"NASA and Boeing leadership are adjusting the return to Earth of the Starliner Crew Flight Test spacecraft," the U.S. space agency stated in a post published late Friday night.

The ship took off from Florida on June 5.
