The planned return of Indian-origin astronaut Sunita Williams to Earth has been postponed once more due to a series of technical issues with her spaceship, the Boeing Starliner. After spending a week in space, the astronaut, who departed Earth on June 5, was scheduled to return on June 14. Her return, though, wasn’t until June 26. NASA hasn’t yet revealed a revised return date for her. According to reports, the space agency decided to prolong Ms. Williams’ stay on the space station following the discovery of five helium leaks on the Starliner spacecraft and problems with five of its 28 thrusters. For a safe return, a minimum of 14 thrusters are required.
