STS-114 was the first "Return to Flight" Space Shuttle mission following the Space Shuttle Columbia disaster. Discovery launched at 10:39 EDT (14:39 UTC), 26 July 2005. The launch, 907 days (approx. 29 months) after the loss of Columbia, was approved despite unresolved fuel sensor anomalies in the external tank that had prevented the shuttle from launching on 13 July, its originally scheduled date.
