NASA launch commentator George Diller called the Atlas 5 with Cygnus, his final liftoff as the voice of launch control before retirement next month. He has worked at the Kennedy Space Center for nearly four decades and served as the commentator for such memorable launches as Hubble, Cassini, Mars Pathfinder, the Spirit, Opportunity and Curiosity rovers and the final space shuttle mission.

A SpaceX-owned Dragon supply ship packed with nearly three tons of cargo arrived at the International Space Station on Monday after a three-day trip from Cape Canaveral. The station’s robotic arm grappled the cargo capsule at 6:54 a.m. EDT (1054 GMT).
