NASA's Space Shuttle Discovery has been taken to the launch pad but a small 1.5-inch crack in the external fuel tank's foam insulation caused a small delay. However NASA said that the crack is only a minor flaw and that it won't threat the mission.
The space agency said that it's a very small crack in an insignificant position. Mike Leinbach, shuttle launch director, stated that they rolled on out and are going to fly with it just as it is. Discovery is planned to be launched next month.
