Scott Kelly and crewmates bid goodbye to space station

NASA has selected Axiom Space, a Houston-based startup partnering with Boeing and other aerospace contractors, to attach a commercial habitat to the International Space Station and begin constructing an orbiting complex that the company says could ultimately replace the international research outpost.

Boeing’s Starliner capsule, carrying an instrumented astronaut test dummy nicknamed “Rosie,” is on track for launch Friday on an unpiloted test flight to the International Space Station, mission managers said Tuesday. The flight is a major milestone in NASA’s push to resume launching U.S. crews from American soil.

A Russian cosmonaut, his Canadian co-pilot and a NASA flight engineer boarded their Soyuz spacecraft, undocked from the International Space Station and plunged back to Earth Monday evening, landing on the balmy steppe of Kazakhstan to close out an action-packed 204-day mission.
