After Boeing discloses major software glitches that had previously gone unannounced from December’s uncrewed test flight of the human-rated CST-100 Starliner space vehicle, the vehicle is grounded pending a second test flight that can demonstrate the issues in question have been corrected. The software glitches include the onboard computer’s event timer being off by 11 hours, and a second glitch, had it not been discovered, would have caused the Starliner command module and its separated service module to collide before re-entry – an event likely unsurvivable in a crewed mission. Boeing and NASA will both participate in the investigation of the issues before certifying the Starliner for another flight.
