Starliner test flight to use special Atlas 5 configuration, unusual launch trajectory

December 19, 2019 Stephen Clark

The 81st flight of a United Launch Alliance Atlas 5 rocket, set for liftoff Friday from Cape Canaveral, will come with its share of firsts when it sends Boeing’s Starliner crew capsule toward the International Space Station on an unpiloted test flight. The launcher will fly without a payload shroud, which typically envelopes satellites during liftoff, and it will debut an uprated dual-engine Centaur upper stage that will power the Starliner on a unique suborbital trajectory optimized for astronaut comfort.
