The latest launch date was announced late Wednesday evening, following a Tuesday night notice that May 25 was off the table. Liftoff of the Atlas 5 rocket on June 1 is set for 12:25 p.m. EDT (1625 UTC).

Flying with a reused first stage and a recycled Dragon supply ship, a SpaceX Falcon 9 rocket lifted off from Cape Canaveral on Friday bound for the International Space Station on an unpiloted cargo delivery mission.

A commercial Cygnus resupply craft that received a new corporate owner while berthed at the International Space Station — thanks to Northrop Grumman’s acquisition of Orbital ATK in June — departed the research complex Sunday. The supply ship was released by Canadarm 2 on the space station at 8:37 a.m. EDT (1237 GMT).
