It’s been a long three-and-a-half years since the Orion spacecraft first launched into space in December 2014, making a successful shake-out flight. But now, NASA’s program aimed at building a large, deep-space capsule capable of sending astronauts to and from lunar orbit is finally ramping back up toward a series of test flights.
In less than a year, a boilerplate model of the Orion spacecraft will be jettisoned from its rocket at 55 seconds after liftoff to test the vehicle’s launch abort system. Provided that goes well, about a year after that, the Orion spacecraft will be sent into lunar orbit for longer than a week for a shakedown cruise. Finally, as early as June 2022, two to four astronauts will fly aboard Orion into lunar orbit, sending humans into deep space for the first time since 1972.
This isn’t exactly a rapid cadence of flights, but three missions in four years would represent a remarkable increase from the vehicle’s flight rate to date—one in 13 years. “Our destiny is to explore, so you want to get your tests behind you and get humans on the spacecraft, and start that exploration,” Annette Hasbrook, an assistant manager for the Orion program in Houston, told Ars.
