Not for refulling geosynchronous satellites though as the shuttle only goes up 300Km or so (Low Earth Orbit?). unless the satellite thought "ohh, need fuel", dropped to a lower orbit, picked up some gas & then nipped bak to higher orbit? EssoSpace division :)

must find the rather cute java app showing satellites orbits, can drag it around, rotate the earth, zoom in & out, highlist specific satellites. GPS satellites on that looked like a crowd of angry flies buzzing round the earth, with LEO satellites making a close to the surface sphere, the bunch of geostationary ones making a Saturnesque ring, and things like Chandra nipping well away from Earth then zooming back :)
