In January 2009 the Air Force announced that a malfunctioning component has postponed the launch date on its Minotaur rocket. However, in March 2009 it was announced that the component issues had been resolved and a launch date was set for May 5, 2009. The May 5 launch attempt was scrubbed and a new launch date was set for May 19, with a backup date of May 20. The launch occurred successfully at 23:55 UTC on 19 May, 20 minutes into a launch window running from 23:35 to 03:30 (7:35 PM to 11:30 PM local time) each night.
