My Idea for Nasa...

I am sure you folks at nasa get alot of crackpot emails with ideas. here is another. if you are going to house shuttle crew members at the space station in case of a problem with the shuttle, how come a rescue as follows can't be built. an apollo/soyuz type capsule, large enough to carry whatever the maximum amount of personal (including station occupents) back to the earth. What I would propose is an unmanned ship is built, and kept ready to roll out in case of an emergency. so that it could be fueled and ready to go in however many days it takes to make something like that ready to fly. launch it unmanned, like a progress ship is, and have it dock with the station. that way it is large enough to carry all personal without risking more lives in the launch. it is a one time use rescue vehicle that only carries what is needed to launch, dock, and return to earth. anything is going to cost alot of money, and while I in no way pretend to be a scientist or rocket jockey, I am a taxpayer that feels strongly about space exploration. Saying that, I also want the money and risk of lives to be done in the best possible manner. This is my idea. I know it could be done. I want to know why it won't be done. What are the drawbacks to it.

I sent this email to Nasa today. While I don't expect to get an answer back, I do wonder why this wouldn't be done. I know it can and of course since it is my idea, I think is should. But I am sure NASA has many reasons it is not feasible.
