Stats: Atlas 5 history and backlog

United Launch Alliance is pushing back its next Atlas 5 launch from Cape Canaveral until no earlier than Aug. 8, allowing time for engineers to ensure an unspecified anomaly during component testing at a supplier will have no impact on the Atlas 5’s mission to place a U.S. Air Force communications satellite into orbit.

On top of an Atlas rocket, the place where orbital spaceflight for American astronauts began, will sit Boeing’s Starliner spacecraft to launch humans into space starting next year.

Five years after winning $1 billion from NASA to mount the first U.S. asteroid sample return mission, scientists and engineers will get their last look at the OSIRIS-REx spacecraft this week as it is closed up inside the nose cone of an Atlas 5 rocket for launch in September.
