You know, the wall of a space station is neither a tin can nor a paper bag -- it's a complex sandwich of thin layers enveloping a lot of wiring and tubes. Anything that holes the enclosure with sufficient enthusiasm to make an interior stowed "quick patch kit" worth a shirtsleeved astronaut's time to deploy is also likely to play hell with Station systems, and possibly spew some dangerous stuff around. What's more, with the module designs I've seen, it's overwhelmingly unlikely that a breach will be conveniently accessible for "slap" patching. It'll more likely be behind one of the zillions of consoles, cabinets and racks of equipment covering the module walls, or beneath the 'floor'. ** Presumably most significant impacts will dissipate their energy on an outer layer. If anything makes it all the way through, SOP will probably be to get the hell out of that module and worry about patching later. ------------------------------ ** As a side note, one of the touches I liked about last year's underrated adventure epic THE ABYSS was the scene where Harris and Mastrantonio's minisub gets banged around and starts leaking. (Fear not, I won't spoil the plot...) For once, the leak is BEHIND A CABINET! and thus tough to stop, instead of smack in the middle of a conveniently empty bulkhead as in so many creaky undersea/space flicks. ------------------------------ Date: 17 Feb 90 15:13:17 GMT From: usc!cs.utexas.edu!jarvis.csri.toronto.edu!helios.physics.utoronto.ca!ists!yunexus!utzoo!utgpu!watserv1!watdragon!watyew!jdnicoll@ucsd.edu (Brian or James) Subject: Re: inter stellar travel There seems to be a fairly strong 'who needs planets' contingent on sci.space. One of the really nice thing about habitable planets is that (within certain limits, of course) life support doesn't depend on the local humans to keep functioning. Imagine Lebanon's civil war in a L-5 style community. IMHO, perhaps high tech civilizations would prosper without the need for large passive life support systems (Passive from the human POV, I mean) but I really wonder if they could survive social upheavals. Of course, that doesn't mean the 'Onealers' won't occur, just that from time to time, the poor people 'trapped' on planets might be needed to restart Oneal civilizations. (Perhaps planets should read planet, the pessimsts are correct about the chances of a life bearing planet having a niche for us to fill. I've always been a fan of terraforming barren worlds and gene tinkering humans to fit local ecosystems, myself).

Please don't just say that SPACE DIGEST is an > INTERNET designation - we newcomers need to also find out what INTERNET is. Let's see if we can unconfuse you simply. Space Digest is an e-mail message which 'contains' a number of mail messages that have been either sent to space+@andrew.cmu.edu or to the sci.space Usenet newsgroup. You probably read the sci.space newsgroup, so you see individual messages just like any other newsgroup. However, for people who do not have Usenet feeds, they would not be able to see sci.space messages at all unless someone mails them. That's what the digest does. It packages up a bunch of the messages and sends 'em out to us (I get mine that way since mvac23 doesn't have a Usenet feed). Internet? Well, basically it can (loosely) be said to be the group of networks which have e-mail addresses of the form user@host.subdomain.sub- domain.domain (ie. space@andrew.cmu.edu). If you are new at the e-mail game, I'd search out a member of the computing staff at your location and put your questions to them. - tom -- internet : mvac23!thomas@udel.edu or thomas%mvac23@udel.edu uucp : {ucbvax,mcvax,psuvax1,uunet}!udel!mvac23!thomas Europe Bitnet: THOMAS1@GRATHUN1 Location: Newark, DE, USA Quote : Virtual Address eXtension.
