Terminal Count Briefing Underway

The launch conductor is leading a terminal count briefing with the launch team. There are three control rooms: the United Launch Alliance’s Atlas Spaceflight Operations Center on the Cape Canaveral Air Force Station; the Boeing Mission Control Center at Kennedy Space Center; and the Space Station Control Room at Johnson Space Center in Houston. NASA’s Emergency Operations Center also is activated, and United Launch Alliance has teams in Denver who will monitor ascent of the rocket.
