Photos: Atlas 5 rocket on the pad with WorldView 4 satellite

United Launch Alliance’s final Delta 2 rocket is now on display at the Kennedy Space Center Visitor Complex in Florida, a monument to an industry workhorse that helped build the GPS navigation satellite fleet and enabled a new era of Mars exploration.

A United Launch Atlas 5 rocket is set to loft three military satellites for the U.S. Air Force on a mission codenamed AFSPC 11. This timeline shows the major mission events planned over a six-hour flight to a near-geostationary orbit.

Firing through a veil of fog blanketing California’s Central Coast, a Falcon 9 launcher climbed into orbit Wednesday with 10 more satellites for Iridium’s voice and data relay constellation, pushing the upgraded network closer to completion as SpaceX accomplished another landing of the rocket’s first stage booster.
