Launch delayed due to hail damage

I'm sure you're aware by now of the hail damage to the external tank of Space Shuttle Atlantis. Below is a picture of some of the damages found on the external tank from the strong thunderstorm Monday evening. Here's a picture of a large piece of hail from that evening and some damages to the external tank. This impact will require the shuttle stack to be moved back to the Vehicle Assembly Building (VAB) for repairs, delaying launch on a space station assembly mission from March 15 to late April.
