Debris Seen Falling Off Shuttle During Launch

kushboy writes "According to an article on CNN.com, there is video of debris falling off Discovery during its launch earlier today. While the debris does not appear to hit the shuttle, extra precaution and more video will be analyzed due to the Columbia mission of 2003. 'NASA has taken steps to minimize the amount and size of debris falling off the shuttle's exterior tank during its ascent. But the space agency has said it's impossible to eliminate falling launch debris.'"
