The launch was originally scheduled to occur in 2007, and later March 2008, however this was delayed until 24 April 2008. The launch attempt on 24 April 2008 was scrubbed for "technical reasons". This was later determined to be a problem with the erector/transporter system, which had failed to retract and move away from the rocket.
