Live coverage: Indian PSLV launches with RISAT 2B radar satellite

Touching down after 340 days in orbit, astronaut Scott Kelly and cosmonaut Mikhail Kornienko have returned to Earth from the International Space Station aboard a Soyuz crew capsule commanded by Sergey Volkov. Landing in Kazakhstan occurred at 0426 GMT Wednesday (11:26 p.m. EST Tuesday).

One-half of the instrument payload aboard NASA’s $916 million Soil Moisture Active Passive satellite has failed after collecting just two months of data, NASA announced Wednesday after weeks of troubleshooting turned up no progress in recovering the sensor.

Ready for a flight to the International Space Station, SpaceX’s first upgraded Dragon cargo capsule rolled out to pad 39A at NASA’s Kennedy Space Center in Florida this week in preparation for launch on top of a Falcon 9 rocket.
