Photos: Atlas 5 rolls out for launch

A billion-dollar missile warning satellite built by Lockheed Martin for the U.S. Space Force arrived at Cape Canaveral earlier this month to kick off final preparations for launch May 17 aboard a United Launch Alliance Atlas 5 rocket.

The United Launch Alliance Atlas 5 rocket with the Air Force’s X-37B spaceplane lifts off at 11:05 a.m. EDT from Complex 41 at Cape Canaveral Air Force Station in Florida.

The U.S. Air Force on Friday made its first public confirmation that the X-37B unmanned space shuttle will be launched next month on the fourth flight of an Orbital Test Vehicle.
