Video: Fourth X-37B launch highlights

A payload critical to the nation was mounted atop its Atlas 5 rocket this morning in preparation for next week’s launch into orbit.

This collection of photographs shows the Air Force’s Global Positioning System 2F-12 navigation satellite being encapsulated in the United Launch Alliance Atlas 5 nose cone and hoisted atop the rocket for flight on Friday morning.

Rocket Lab’s Electron rocket is set to launch 13 CubeSats Saturday night (U.S. time) under contract to NASA from the company’s privately-owned spaceport in New Zealand, a pathfinder mission that could pave the way for more NASA satellites to hitch a ride on future Electron flights.
