A new launch date has been established — June 9 — for the Delta 4-Heavy rocket to carry a classified satellite into space for U.S. national security needs.

Rolling toward a mid-May deployment of a clandestine spy satellite, United Launch Alliance’s triple-body Delta 4-Heavy rocket moved from its Cape Canaveral assembly building to pad 37B yesterday.

NASA simulated an in-flight launch abort of an Orion crew capsule high above Cape Canaveral on Tuesday, in a major test of the safety system that would whisk astronauts on future moon missions away from a failing rocket.
