Default Re: Nasa - why is shuttle placed on 'rescue' launch pad??

From what I read from NASA it's because the Hubble is in a much higher orbit that the ISS. So if anything happens during launch like another hunk of foam making a hole. the Shuttle would be unable to reach the ISS , ( i'm not sure of the reasoning) So they have the next Shuttle ready to go do the rescue.
