Live coverage: Falcon 9 soars into space with DSCOVR

NASA astronauts Bob Behnken and Doug Hurley completed their final training sessions in Houston this week before their scheduled May 27 liftoff on a SpaceX Dragon spacecraft from the Kennedy Space Center, the first launch of humans from the Florida spaceport since 2011.

The Starlink 10-25 mission will also set a new reuse milestone for the first stage booster, which is flying for a record-setting 29th time. Liftoff from pad 40 at Cape Canaveral Space Force Station is scheduled for 2:28 a.m. EDT (0628 UTC).

SpaceX’s first Falcon 9 Block 5 rocket, sporting changes to make the booster easier to reuse, rolled out of its hangar and up the ramp to launch pad 39A at NASA’s Kennedy Space Center on Thursday ahead of a planned hold-down engine firing.
