Photos: Tuesday’s Atlas 5 rollout

A European Ariane 5 rocket took off on its first flight of the year Wednesday with a new-generation communications satellite for Intelsat, lighting up the sky over its French Guiana launch base as it arced over the Atlantic Ocean.

Two key pieces of hardware needed for NASA’s next Mars rover — an Atlas rocket booster and sterile components of the rover’s sample collection system — recently arrived at Cape Canaveral ahead of the mission’s scheduled launch July 17.

Likened to raising a cellular tower 22,300 miles high, a United Launch Alliance Atlas 5 rocket will put the Navy’s fourth mobile communications satellite into space to expands the rugged smartphone system to global coverage.
