Boeing’s Starliner leaves space station for Earth – without its astronauts

The Nasa astronauts Suni Williams and Butch Wilmore should have flown the Starliner back to Earth in June, a week after launching in it. But thruster failures and helium leaks marred their ride to the space station. Instead, they will remain at the ISS for the rest of the year and will return in February aboard the SpaceX Dragon spacecraft.
