Sunita Williams, Barry Wilmore, In Space For 80 Days, To Return Next Year: NASA | Read

Two NASA astronauts who flew to the International Space Station in June aboard Boeing's faulty Starliner capsule will need to return to Earth on a SpaceX vehicle early next year, NASA said on Saturday, deeming issues with Starliner's propulsion system too risky to carry its first crew home.

The agency's decision, tapping Boeing's top space rival to return the astronauts, is one of NASA's most consequential in years. Boeing had hoped the test mission would redeem the Starliner program after years of development problems and over $1.6 billion in budget overruns since 2016.
