Two and a half years after an initial orbital flight test fell short, Boeing is trying once again to put its CST-100 Starliner space capsule through an uncrewed trip to the International Space Station and back.
United Launch Alliance’s Atlas 5 rocket sent Starliner spaceward from Cape Canaveral Space Force Station in Florida at 6:54 p.m. ET (3:54 p.m. PT) today. Boeing and NASA are hoping that this second orbital flight test, known as OFT-2, will pave the way for Starliner’s first crewed flight later this year.
Within OFT-2’s first hour, Starliner separated from the Atlas 5 rocket’s Centaur upper stage and executed an engine burn to reach its intended orbit. “It’s a major milestone to get behind us, but it is really just the beginning,” NASA commentator Brandi Dean said. “We’ve got a number of demonstrations now that the Starliner will have to go through ahead of its International Space Station arrival.”
Boeing has received billions of dollars from NASA to develop Starliner as an alternative to SpaceX’s Crew Dragon for sending astronauts into orbit. NASA’s arrangement with SpaceX and Boeing has been compared to a taxi service, with the space agency paying the spacecraft providers for rides.
