MEXICO CITY - Boeing's new Starliner unmanned spacecraft returned to Earth on Sunday, landing in the New Mexico desert in the United States six days early after a clock problem prevented a rendezvous with the International Space Station.
Images broadcast by NASA showed the spacecraft touching down safely in the dark after a descent slowed by three large parachutes.
The Starliner capsule was launched Friday from Cape Canaveral in Florida, but shortly after separating from its Atlas V launch rocket, its thrusters failed to activate as planned, preventing it from reaching an orbit high enough to meet up with the ISS.
The space station orbits at an altitude of about 400 kilometers (250 miles) above sea level.
The flight -- carrying only a dummy -- was meant to be a final dress rehearsal before a crewed flight.
After calculating that the craft had burned too much propellant for several minutes, Boeing and NASA were forced to guide the Starliner back to Earth without fulfilling its planned mission.
Jim Chilton, senior vice president of Boeing's space and launch division, told reporters that "we started the clock at the wrong time."
Starliner's failure was the latest serious setback for Boeing, which is still reeling from two fatal crashes of its 737 Max airliner. The crashes, in October 2018 in Indonesia and in March 2019 in Ethiopia, claimed a total 346 lives.
Boeing plans to suspend production of the plane in January.
NASA administrator Jim Bridenstine insisted that the space mission was not a complete failure.
"The NASA team and the Boeing team have been working hand in glove to accomplish as many of the test objectives as we can," he said before the landing.(FA)
