Starliner spacecraft cleared for undocking and re-entry

Astronauts on the International Space Station closed the hatch to Boeing’s Starliner spacecraft Tuesday, and ground teams used the lab’s robotic arm to inspect the capsule’s heat shield to clear the test vehicle for undocking Wednesday and return to Earth for a late afternoon landing in New Mexico.

The Boeing-owned spacecraft launched last Thursday and docked at the space station Friday night, reaching the orbiting research complex for the first time after officials aborted a test flight in 2019. The unpiloted demonstration mission is set to conclude Wednesday with an automated departure from the space station, followed a few hours later by a parachute-assisted, airbag cushioned landing at White Sands Space Harbor.

NASA astronauts Kjell Lindgren and Bob Hines closed the forward hatch to the Starliner spacecraft at 3 p.m. EDT (1900 GMT) Tuesday. Hines became the first person to enter a Starliner spacecraft in orbit Saturday, when the station crew opened the hatch and began three days of inspections and checkouts inside the capsule’s crew cabin.

Lindgren and Hines, who arrived at the station on a SpaceX Dragon capsule last month, performed several tests inside the Starliner capsule during its docked stay at the space station. They performed communications checks inside the Starliner spacecraft, unpacked about 500 pounds of cargo, then replace it with about 600 pounds of cargo for return to Earth.

The Starliner is scheduled to undock from the station at 2:36 p.m. EDT (1836 GMT) Wednesday, then back away to a safe distance from the complex before a 58-second braking burn at 6:05 p.m. EDT (2205 GMT) to drop out of orbit.

Boeing’s Starliner spacecraft returns to Earth, wrapping up critical test mission

It’s been a long road, but Starliner has finally flown to and from the space station

After spending a little less than a week at the space station, Boeing’s new passenger spacecraft, the CST-100 Starliner, returned to Earth this afternoon, landing intact with the help of parachutes and airbags in the New Mexico desert. The successful touchdown brings an end to a crucial test flight for Starliner, one that showcased the vehicle’s ability to launch to space, dock with the station, and then return home safely.

Shaped like a gumdrop, Boeing’s Starliner capsule was built in partnership with NASA in order to launch the agency’s astronauts to and from the International Space Station, or ISS. The mission is part of NASA’s Commercial Crew Program, which challenged private companies with creating space taxis to carry people to low Earth orbit. But before NASA will let its personnel ride on the vehicle, the space agency wanted Starliner to demonstrate that it could go through all the motions of a trip to the ISS — without people on board.

With today’s landing, that uncrewed test flight — called OFT-2 — has come to an end, with Starliner performing every major step it was meant to accomplish. The capsule successfully launched to orbit on May 19th, riding to space on top of an Atlas V rocket; it approached and docked with the ISS on May 20th; and it undocked with the space station this afternoon before heading home. It wasn’t a completely smooth flight, though. Throughout the mission, Starliner encountered a number of issues with its various thrusters, tiny engines used to maneuver and propel the vehicle through space. None of those problems proved to be fatal for the flight, though, and Starliner was able to complete OFT-2 as planned.
