Live coverage: Irma knocks out power at Kennedy Space Center

During a visit to Cape Canaveral this week, NASA astronauts Doug Hurley and Bob Behnken strapped in to the SpaceX crew capsule they will ride into orbit as soon as mid-to-late May. Next week, the astronauts will be in Houston to continue training for an extended stay on the International Space Station that could last two-to-three months.

Wrapping up a busy week on the International Space Station, a crew of three boarded their Soyuz landing craft and headed for Earth on Friday. Cosmonaut Gennady Padalka, the most experienced space crewman in history, was at the controls, along with Danish and Kazakh crew members, and landed in Kazakhstan at 8:51 p.m. EDT Friday (0051 GMT Saturday).

Rainy weather expected across Central Florida this weekend has a 50-50 chance of preventing the launch of a SpaceX Falcon 9 rocket Saturday on a resupply mission to the International Space Station, U.S. Air Force forecasters said Wednesday.
