The Boeing Starliners is returning to an uncertain future

The first test flight of Boeing’s CST-100 Starliner spacecraft, with astronauts Butch Wilmore and Suni Williams on board, ended after seven years. The test flight lasted for eight days and had to be extended when some thrusters failed while the spacecraft was approaching the International Space Station. It’s part of Boeing’s contract with NASA to fly astronauts to and from the ISS.
