Boeing's Starliner spacecraft is open for astronauts at space station for 1st time - Space.com

Boeing's first Starliner capsule to the International Space Station is officially open for astronauts living on board  the orbiting lab. .

The commercial Starliner spacecraft, which arrived Friday on an uncrewed test flight to the station, was opened by NASA astronaut Robert Hines at 12:04 p.m.

It's a major milestone for Boeing and NASA's Commercial Crew Program, which picked Boeing and SpaceX to fly astronauts to the International Space Station in 2014.

"This is the day that they envisioned, where we have three human-rated vehicles docked at the space station right now," Hines said, referring to Starliner, SpaceX's Crew Dragon and Russia's Soyuz capsule.

 Those problems did not resurface for Starliner's current test flight, called Orbital Flight Test-2 (OFT-2).

Staying on board Starliner will be Boeing's test dummy, affectionately dubbed Rosie the Rocketeer, after Rosie the Riveter of World War II-era fame.

Starliner is scheduled to return to Earth following a four- to five-day stay at the space station, a timeline largely dictated by weather at the vehicle's potential landing sites in the western United States. 

Boeing also added an extra bit of fun to Starliner's trip to the space station in the form of a plush toy of Jebediah "Jeb" Kerman, a Kerbonaut from the hit space exploration game Kerbal Space Program, which Boeing used as a zero-g indicator to show when the capsule reached space
