There is a useful distinction between building a satellite that must be SERVICED by the shuttle (boards replaced, film collected, whatever) and one that must actually be REBOOSTED by it. The former is merely questionable, the latter is downright dangerous. It ought to be an international agreement that anything large enough to be dangerous on re-entry must orbit high enough to stay up for decades. LDEF, Max, Skylab, and all that Soviet iron are Damoclean hazards. Not to mention damn expensive to lose at a year's slippage. -- There's nothing wrong with Southern California that a || Tom Neff rise in the ocean level wouldn't cure. -- Ross MacDonald || tneff@bfmn0.UU.NET
