Boeing’s Starliner glitches prompt NASA to delay astronauts’ return from space station.

NASA astronauts Sunita Williams and Butch Wilmore are still stuck at the International Space Station (ISS) as engineers continue to fix the Boeing Starliner spacecraft that will take them back to Earth.

Five of the capsule's 28 thrusters went down during docking; all but one thruster was restarted. Starliner already had one small helium leak when it rocketed into orbit, and several more leaks sprung up during the flight.
