NASA astronauts living aboard the International Space Station closed the hatch of Boeing’s CST-100 Starliner spacecraft at 3 p.m. EDT Tuesday, May 25. The uncrewed spacecraft is scheduled to autonomously undock from the space station to begin the journey home at 2:36 p.m. EDT Wednesday, May 25. NASA and Boeing are targeting 6:49 p.m. for the landing and conclusion of Orbital Flight Test-2, wrapping up a six-day mission testing the end-to-end capabilities of the Starliner system.
