Imnot sure if this idea is feasible, but, its an idea..` What about pre-positioning feul/food/gear packets along the route of the Mars mission or maybe send a unmanned mission ahead maybe by Solar Sailer(s). And pre-[.positioning the craft to be near na..mars when the Mir mission arrives at Mars. Michael C. Adams NSMCA@ACAD3.ALASKA.EDU 0 8

Adams > NSMCA@ACAD3.ALASKA.EDU Your first idea would be good on an arctic expedition, or even on a lunar traverse, but not on a trip to Mars, since everything bewteen here and there ALSO has to be revolving around the Sun: different distances from the Sun = different periods of revolution. You could drop stuff off evenly spaced between here and Mars, but when you got to that distance, they would no longer be lined up, having travelled along their orbital paths since they were left. The second idea of sending some sort of resupply craft ahead, and parking it in Martian orbit where you could find it, redezvous with it, dock and transfer from it, is a MUCH better suggestion!

Maybe a multiple stage pre-positioning nission.. Why must the big stuff, the extra food/supplies be sent with the quick human mission.. The slow part can get there a year or two before the human mission, and maybe act as a sensor, launch probes and such and maybe act as a NAV bouy.. And maybe do other missions that would make the human mission easier..Do the things that humans don't need to do.. Question what would you use to get it there?? Automated Solar Sail would be nice.. Seems you only need rockets and such when you have to get someplace quick.. The auto-mission would do surveys of possibel landing/survey sights.. Any better ideas are expected..
