Video: Change of command aboard International Space Station

NASA and SpaceX officials are moving forward with preparations to launch the next commercial Crew Dragon mission to the International Space Station next week after a Flight Readiness Review Thursday, pending a final evaluation of a discovery by SpaceX that it has potentially been loading slightly more propellant than expected into its Falcon 9 rockets.

A Russian Soyuz rocket blasted off from Kazakhstan Friday, boosting a three-man crew into orbit for a six-hour flight to the International Space Station.

A Soyuz rocket and Progress supply ship packed with nearly 3 tons of cargo, provisions and fuel for the International Space Station rolled out to a launch pad at the Baikonur Cosmodrome in Kazakhstan on Monday.
