How close to the fuselage?
The fact that it's even public knowledge makes me wonder, this sounds similar to what caused the disintegration of STS-107. Last time they refused to get a satellite to have a closer look in orbit when it was suggested by engineers. If they want any kind of budget from Obama going forward, they'd better make damn sure it's OK this time.
Still, here's to looking out of a nice clean Hubble, and the safe return of Atlantis.
