Photos: Tuesday’s Atlas 5 rollout

United Launch Alliance has begun stacking its first Atlas 5 rocket to fly in service to the International Space Station, a commercial mission to send supplies to the orbiting complex.

Europe’s Galileo navigation program turned to the workhorse Ariane 5 rocket for a heavy lift Thursday, delivering four new satellites to orbit on the launcher’s 75th successful flight in a row and pushing the growing fleet closer to global coverage.

Ready for blastoff just after sunset Wednesday with a classified payload for the U.S. government’s spy satellite agency, a United Launch Alliance Atlas 5 rocket rolled out to its launch pad at Cape Canaveral late Tuesday afternoon after an unplanned trip back inside its integration building for repairs.
