Ok Not to be a total NERDhere but I guess My inner pocket protector will now show itself. The Drag that you are talking of is a gravitational force, the pull of the earth on the ISS which slows its speed down andbynot maintaining the optimal speed to maintain the desired altitude it falls towards earth. Not like you might think where it just drops likeWiley coyote from a cliff after he holds up the sign HELP! but a gradual fall slowly drawing closer to the earth. Until it starts to experience theAtmosphere. Then It will be traveling at such aspeed that it will now have oxygen rushing across all of the unprotected surfaces and heating them up until the ISS itself looks like a shooting star streaking across the sky.About what Columbia looked like. Only ISSis bigger.There isnt any Oxygen molecules in space to produce such a drag, that I believe you are refferencing. This Same Force has been used in the calculations to go to the moon and beyond. (Slingshot) How long do we burn the OMS? how long to go around this planet and then speed up to break its gravitational pull to go in the desired pathto go tothat one?OK I dont work there any more and I have to get back to painting peoples toys. Thanks for posting earlier. And Fort worth we do not have a problem. lol...</p>
