NASA Orion Launch Canceled

After facing multiple delays, the launch of NASA’s Orion spacecraft was scrubbed Thursday and will be rescheduled. NASA had a 2.5-hour window to launch the spacecraft, beginning at 7:05 a.m. It had been delayed by a boat straying in the launch danger zone, a stuck liquid-oxygen drain valve on the rocket’s booster engines, and wind gusts. NASA’s plan, in decades to come, is for the Orion to bring people back and forth to Mars.
