Several NASA astronauts, plus Boeing test pilot Chris Ferguson, recently participated in a training session at Cape Canaveral, practicing how they would evacuate from the Atlas 5 rocket’s launch pad in the event of a countdown emergency.

Atlas 5 rocket hardware and a U.S. Air Force communications satellite have arrived at Cape Canaveral for United Launch Alliance’s next mission, scheduled for liftoff June 27.

The United Launch Alliance Atlas 5 rocket lifted off Thursday night at 10:44 p.m. EDT (0244 GMT) with NASA’s four formation-flying MMS satellites.
