Live coverage: Irma knocks out power at Kennedy Space Center

NASA and SpaceX have set April 22 as the target launch date for the next Crew Dragon flight to the International Space Station. The four-person crew will be the first to ride a previously-flown Falcon 9 booster and a reused Dragon spacecraft, and a NASA official said this week that the launcher and capsule are in “really good shape” as refurbishment wraps up at Cape Canaveral.

Russian cosmonaut Anatoly Ivanishin, Japanese flight engineer Takuya Onishi and NASA astronaut Kate Rubins departed the International Space Station on Saturday and headed for a homecoming in Kazakhstan to wrap up a 115-day expedition in orbit. Undocking occurred at 8:35 p.m. EDT Saturday (0035 GMT Sunday), with an on-target landing more than three hours later at 11:58 p.m. EDT (0358 GMT).

The U.S. Air Force fired a new rail-launched rocket into space from Hawaii at 10:45 p.m. EST Tuesday (0345 GMT Wednesday), but the Super Strypi vehicle failed about a minute after liftoff with 13 satellites on-board.
