The Boeing Starliner on which Indian-origin NASA astronaut Sunita Williams flew to the International Space Station (ISS) on June 5 was touted as a space capsule made by astronauts for astronauts but, much to the embarrassment of Boeing, is now set to return without any human spacefarers. The return journey, in autonomous mode, is slated for September 6 and the Starliner is expected to land about six hours after it undocks.
