CAPE CANAVERAL, Fla. (Reuters) - Boeing Co successfully launched its new astronaut capsule on Friday on an unmanned debut journey to the International Space Station, a milestone test for the U.S. aerospace firm that is vying with SpaceX to revive NASA's human spaceflight capabilities.
Boeing's CST-100 Starliner spacecraft, a cone-shaped pod with seven astronaut seats, blasted off from Florida's Cape Canaveral at 6:36 a.m. (1136 GMT) atop an Atlas V rocket from Boeing-Lockheed Martin Corp's United Launch Alliance.
Minutes after liftoff, Starliner detached from the main rocket booster, aiming for a rendezvous some 254 miles (409 km) into space on Saturday morning with the International Space Station.
The test is one of the most daunting milestones required by NASA's Commercial Crew Program to certify the capsule for eventual human spaceflight - a long-delayed goal set back years by development hurdles from both Boeing and SpaceX.
Despite the delays, and a blistering November government watchdog report that found Boeing received an "unnecessary" contract boost from NASA, a successful mission would hand Boeing an engineering and public relations win in a year punctuated by a corporate crisis over a ban on its 737 MAX jetliner following fatal crashes.
Boeing was awarded $4.2 billion (3.23 billion pounds) and Elon Musk's SpaceX $2.5 billion by the U.S. space agency in 2014 to develop separate capsule systems capable of ferrying astronauts to the space station from American soil for the first time since the U.S. Space Shuttle was retired from service in 2011.
The program, primarily meant to end America's reliance on Russia's space program for rides to the space station, had initially expected its first crewed flights on Starliner and SpaceX's Crew Dragon capsule in late 2017. A slew of design and safety concerns for both vehicles have led to schedule delays.
The current target date for the first crewed flight is planned for mid-2020 for Boeing and SpaceX.
Occupying one of Starliner's astronaut seats on Friday was a mannequin named Rosie, outfitted with sensors to measure the pressure a real astronaut would endure on ascent to the space station and during hypersonic re-entry back through Earth's atmosphere.
If all goes to plan, Starliner will stay at the space station for a week before undocking and beginning its return to Earth early on Dec. 28, deploying three parachutes to slow its descent to the desert surface of White Sands, New Mexico.
SpaceX's Crew Dragon capsule carried out its unmanned test flight to the space station in March.
