Photos: More shots of Saturday’s Delta 4-Heavy rocket Launch

Ground crews in French Guiana on Monday transferred an Ariane 5 rocket to its launch pad, moving the vehicle into position for liftoff Wednesday with four European Galileo navigation satellites on the Ariane 5’s last flight with an older-generation, out-of-production upper stage.

United Launch Alliance’s first Vulcan rocket was filled with methane and liquid oxygen propellants at Cape Canaveral last week for a tanking test, but managers decided to move the rocket back inside a hangar for a few adjustments before proceeding with an engine test-firing.
