STS-121 Launch Opportunity

July 4th, 2006

Today’s launch window for STS-121 and Space Shuttle Discovery is from 1:32 PM to 1:42 PM CDT.

The launch attempt today was nearly canceled when a crack was found in the External Tank’s (ET) insulating foam. The crack is only five inches long by an eighth of an inch deep, but these days we take nothing for granted when it comes to that foam. As of now, the launch still seems to be on, but they’re continuing to review and talk about the situation.

If you’re looking for good launch-day coverage, Eric Berger is doing a good job over at his Science Guy blog.
