Live coverage: Three-man crew closes out 173-day space mission

Flight controllers and other essential personnel at NASA’s Johnson Space Center just south of Houston are sheltering in place, maintaining contact with the International Space Station during torrential rain and flooding across south Texas from the slow-moving remnants of Hurricane Harvey.

A three-stage Soyuz booster rocket, capped by a three-person crew transport capsule, rolled out to a launch pad in Kazakhstan on Monday, two days before blasting off with new residents headed for the International Space Station.

Officials from the Norwegian Space Center are looking for another launch opportunity for a microsatellite designed to track ship traffic and study space weather after engineers determined it could not safely be attached to a Soyuz rocket set for liftoff Friday.
