Boeing's troubled Starliner capsule that left two NASA astronauts on the International Space Station last year may need to fly a third uncrewed test flight before it carries astronauts again, agency officials said as the spacecraft's first crew had to return to Earth on a SpaceX capsule this week.

NASA astronauts Suni Williams and Butch Wilmore spoke about their continued stay aboard the International Space Station during a press conference held yesterday. The two are now fully incorporated into the ISS crew, as the Boeing Starliner spacecraft that was meant to take them home last week was instead sent back to Earth uncrewed.
