Leaving its crew behind in orbit, Boeing’s troubled Starliner spacecraft undocked from the International Space Station Friday and chalked up a successful unpiloted return to Earth, closing out a disappointing test flight with an on-target and apparently problem-free New Mexico touchdown.
Despite NASA’s concerns about earlier thruster problems and multiple helium leaks in the ship’s propulsion pressurization system, the Starliner had no trouble undocking and moving away from the station at 6:04 p.m. EDT and executing a critical 59-second deorbit braking maneuver at 11:17 p.m. to drop out of orbit.
