Can someone please elaborate on the new heat shielding being used on Discovery? It is my understanding that tiles have been scrubbed for sheets of material. Also, are there any other major differences in Discovery from Columbia and Challenger? -Dave

The sheets you refer to are blankets made of the same material as the tiles. The tiles are still used on the bottom side of the shuttle, but I believe on the Discovery, the entire top has been redone in blankets. The Challenger had a few blankets, whereas the Columbia had none.
