In the wake of the Columbia accident, NASA eliminated the bipod insulation
directly responsible for the fatal impact and implemented a variety of other
changes to minimize foam shedding. The debris that doomed Columbia was as
big as a suitcase and weighed 1.67 pounds. Engineers believe the largest
piece of foam that might be shed during Discovery's launch is on the order
of a half ounce.

Are there going to be cameras to monitor this?
