Couldn't a (removable) additional fuel tank be mounted in one of the shuttles. And say (for sake of discussion) that this tank took up most or all of the payload area. Then could the shuttle reach high orbits, maybe even geosync. orbit? Would there be any advantage to such a mod? 2. If a sat. is in geosnyc, is it very stable there? Or does it require hydozine adjustments like other lower sats? Will a geosync ever come down if left unattended? 3. What about the LDEF. When Columbia brings it down it will be a record landing weight correct? Is this an area of special concern? Exactly how much does the LDEF weigh? Could any of the shuttles perform this task, or does it require the "Mack Truck" of the fleet? Does this extra weight effect re-entry? (I would expect that it doesn't) 4. This question I just have to ask: Henry S. (In Toronto), how do you know all this stuff? Where do you get these resources? And don't say the library because I looked there, they dont have anything even close to explaining how the shuttle is bolted down until ignition. Do you make any public appearances regarding space technology, if so when and where, (I'll be there!) Please excuse the volume/"scatterness" of questions. Two of us which read this group decided it would be better to save up questions, and take turns posting.
