Snapshots from Atlas 5 launch

NASA astronaut Nick Hague and Roscosmos cosmonaut Alexandr Gorbunov walked through a launch day simulation as NASA and SpaceX prepared to conduct a static fire test of the Falcon 9 rocket. Ignition happened at 10:05 p.m. EDT (0205 UTC).

The next Cygnus resupply mission to the International Space Station set for liftoff Wednesday from Virginia’s Eastern Shore will introduce new capabilities for the commercial cargo freighter, including a longer operating life enabled by fuel-saving gyroscopes to support an extended mission months after the spacecraft departs the International Space Station, Northrop Grumman officials said.

Already encapsulated in the 18-foot-diameter nose cone, the Air Force’s X-37B spaceplane is hoisted atop the Atlas 5 rocket at Cape Canaveral’s Vertical Integration Facility.
