Live coverage: Vega rocket launches with LISA Pathfinder

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.

The European Philae comet lander, out of power and presumably lost after bouncing into heavily shadowed terrain last November, phoned home Saturday after finally getting enough sunlight on its solar panels to transmit data to the Rosetta orbiter for relay to Earth.

Russian Soyuz commander Alexander Misurkin and two U.S. astronauts — flight engineers Mark Vande Hei and Joe Acaba — lifted off Tuesday from the Baikonur Cosmodrome in Kazakhstan. The trio began their six-hour journey to the International Space Station with a launch aboard a Soyuz rocket at 2117 GMT (5:17 p.m. EDT), and docking occurred at 0255 GMT (10:55 p.m. EDT).
