re: Potential damage on Discovery's fuel tank
So what now, an EVA repair mission?
An EVA to repair what? The ET? It's gone, man! Already burned up.
The orbiter Discovery is, so far, very clean. A couple li'l dings on the Thermal Protection System, and that's it. The engineers are still looking at those TPS dings - nobody's saying a 100% - but right now; nothing serious.
Or did I miss your post point?
