Video: NROL-37 payload and Delta 4-Heavy rocket prepped for launch

Go behind the scenes to see the labor it takes to deliver a satellite to its launch base, in this case NASA’s Tracking and Data Relay Satellite-M scheduled for launch Aug. 3 atop an Atlas 5 rocket.

This photo gallery includes a series of spectacular pictures of the launch of an Atlas 5 rocket Nov. 13 from Cape Canaveral with a classified payload for the National Reconnaissance Office.

Now cocooned inside a heat shield and the nose shroud of an Atlas 5 rocket that will send it to Mars, NASA’s InSight lander is awaiting launch May 5 from Vandenberg Air Force Base, California.
