Live coverage: Soyuz crew capsule departs station, lands in Kazakhstan

A Crew Dragon spaceship built and owned by SpaceX glided to an automated docking with the International Space Station Sunday, delivering NASA astronauts Doug Hurley and Bob Behnken to the orbiting research complex after a trouble-free 19-hour flight from the Kennedy Space Center.

A $110 million NASA science instrument twice targeted for cancellation by the Trump administration is set for launch Tuesday inside the trunk of a SpaceX Dragon cargo capsule for delivery to the International Space Station, where it will spend three years charting changing carbon dioxide concentrations in Earth’s atmosphere.

Doug Hurley and Bob Behnken, two veteran space shuttle fliers, are gearing up to fly a privately-developed SpaceX Dragon capsule into orbit this year.  These photos chronicle their recent training.
