Live coverage: Soyuz crew lands in Kazakhstan

The Soyuz booster that will send the International Space Station’s next three residents into orbit later this week rolled out of an integration hangar early Monday and rode a railroad car to its launch pad at the Baikonur Cosmodrome in Kazakhstan.

NASA astronauts Bob Behnken and Doug Hurley will be geared up for the long haul when they launch from the Kennedy Space Center on a SpaceX Crew Dragon spacecraft later this month, but they won’t know exactly how long they will be in orbit until they are already aboard the International Space Station.

Scientists say the touch and go landing by NASA’s OSIRIS-REx spacecraft on an asteroid last month revealed fresh insights into the structure of loose rocks that may cover the surfaces of many small planetary bodies — material that is more akin to a playground ball pit than solid bedrock.
