The launch of NASA’s twin GRAIL spacecraft

The Mobile Service Tower at LC-17B is rolled away from the Delta 2 rocket that launched NASA’s Mars Pathfinder mission on its way to the red planet on December 4, 1996. This video includes footage shot inside the blockhouse at the launch pad.

When the first Delta 2 rocket took off on Valentine’s Day 1989, ideas like navigating by smartphone and driving robots on Mars were science fiction. More than 150 launches over the last 30 years helped change all that.

Brisk upper level winds blowing from the west thwarted a second try to launch a new NOAA weather satellite aboard a United Launch Alliance Delta 2 rocket Wednesday, likely postponing the liftoff from Vandenberg Air Force Base in California until at least Saturday.
