Snapshots from Atlas 5 launch

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.

Calling on the Atlas 5 rocket to flex its muscles one more time, Orbital ATK will partner with United Launch Alliance once again to send a massive load of supplies to the International Space Station astronauts early next year.

The Orion spacecraft slated to fly around the moon on an unpiloted mission next year has arrived back at the Kennedy Space Center following an environmental test campaign in Ohio, ready for a series of final checkouts before officials pause launch preparations this summer to await readiness of NASA’s Space Launch System.
