Rich ------------------------------ Date: Tue, 6 Sep 88 08:38:54 PDT From: hairston%23666%utadnx%utspan.span@vlsi.jpl.nasa.gov Subject: Shuttle names--old and new X-St-Vmsmail-To: JPLLSI::"space@angband.s1.gov" A while back there was a discussion about where NASA got the names for the Shuttle orbiters. Here's the straight dope direct from NASA itself. As you know, the next orbiter is going to be named by a contest in the nation's schools. My wife teaches second grade and just received the entry packet for her class from NASA. The following is taken from that packet: "Each team must propose one name for Space Shuttle Orbital Vehicle (OV) 105. The name must be the name of a sea vessel used in research and exploration. "NASA's first orbiters were named after such sea vessels. The sea-going 'Columbia' entered and explored the mouth of the Columbia River in 1792. 'HMS Challenger' made the first prolonged oceanic exploration cruise; the data gathered about the Atlantic and Pacific Oceans on that voyage became the basis for the study of oceanography. Various ships have borne the name 'Discovery': one of Henry Hudson's in his search for a northwest passage in 1610 and 1611, a second in Captain Cook's voyages of the 1770's, and Commander Robert Scott's steam bark which made the first scientific survey of Antarctica. The ketch 'Atlantis' logged half a million miles between 1930 and 1966 as the first American-operated vessel designed specifically for ocean research. "The space missions carried out by the 'Columbia', 'Challenger', 'Discovery', and 'Atlantis' also have contributed significantly to world research and exploration, making them worthy of sharing the names of their historic predecessors. "The name for OV 105 should be a name suitable for an American spacecraft and should capture the spirit of America's mission in space. In honor of the 51-L crew, the name 'Challenger' has been retired and cannot be used for OV 105." Hmmmm......they didn't mention the "Enterprise". Now I have a question. Back in college in the mid-70's I either read or had someone at JSC tell me that the shuttle names did double duty: they had to represent both a historic research ship AND the name of a famous spacecraft from science fiction. Anyone out there know anything about this? I can get three of them ("Enterprise" from "Star Trek"; "Columbia" was the name of Jules Verne's spaceship in "From the Earth to the Moon", which was why it was also chosen for the command module of Apollo 11; and "Discovery" which was the Jupiter-bound spacecraft in "2001"). Supposedly either "Challenger" or "Atlantis" was the name of Tom Swift's rocket, but I've never been able to track that down for sure. Any sci-fi fans out there have any suggestions or leads? Also, anyone who wants to get contest information, it's open to any school, public or private, grades K through 12th. For an entry packet write to: NASA Orbiter-Naming Program Council of Chief State School Officers 400 North Capitol Street, NW, Suite 379 Washington, DC 20001 Deadline for entries is December 31, 1988.

The British Interplanetary Society published a report of a highly-detailed study called _Project Daedalus_ several years ago, still excellent reading. They concluded that an unmanned, undecelerated flyby of Barnard's Star (12 l.y.) would be technologically and economically feasible in short order given reasonable extrapolations. The mission time was 50 years, with a peak velocity of 12% of the speed of light. I'd recommend reading this report.

Mr Nelson may be right about the dreamers who only watch star trek re-runs. But those aren't the only people out there. As far as I'm concerned there is only one real space program around. That is the one being run by people like Gary Hudsen, Deke Slayton, Max Faget, George Koopman... Because if they succeed, people like me get to go. The only thing I get out of the government space program is the honor of paying taxes. And if these people succeed, it won't be all that long before the treaties simply get relegated to the dustbin where they belong. Space is very very expensive. IF you do it the NASA/AEROSPACE way. It just might be affordable if realistic hard headed businessmen (WITH a dream, not a B-school toilet tissue) do it. Most effort by statist space programs is aimed at creating facilities which will keep people totally dependent. All their pictures, all their efforts are aimed at generating this as the 'weltenschaung' of spcae exploration. I suggest that it is a falsehood that is becoming truth only because no one is putting resources into alternatives. Yet. Let us place ourselves 150 years in the future on the lunar surface. Our trusty prospector is peddling across the lunar maria in his four wheeled prospectors bike.(1) He is wearing a skin tight suit (2) and is protected from the sun by a parasol. Food and Oxygen is purchased from small farm(2.5) homesteads sheltered in craters and powered by small cold fusion generators (3). The cheap CFG will be the equivalent of the modern plow in sofar as opening the lunar land to farming. All electronics is self repairing to a great extent. If not nanotechnology, then something at least as good as far as reliability. All electronics are grown on the homestead by 'blueprints' ordered and delivered electronically out of the 2150 online Sears Catalog. Some very scarce materials are purchased, some of which may be imports. The monetary standard may well be defined in terms of scarce volatiles. Water will be totally recycled. Solid wastes will be used as fertilizer and will be of value. They will probably not have the same standards and taboos about human waste that are prevelant in US urban nonculture. NOTHING will be thrown away. Neighbors will help each other out, as they always do on the frontier. Violence will actually be at a minimum, as it was in truth on the REAL american frontier, and most dispute resolution and land titling will be handled by private agencies.(4) Independent settlers are isolated and quite capable of defending themselves. The dug in nature of their shelters makes them difficult to find by sensors and makes them as impervious to a near miss by a nuke as to a solar flare. With the energy at their disposal with the CFG's and the robotic help, they are quite capable of defending their land. Even a major military ground force would break it's back after taking on a few thousand of them, one at a time. I certainly don't expect that I have accurately describe the technology of 2150. Although the details of HOW things might be done may be totally wrong, I'm sure that if people try to find the solutions, there WILL be ways of doing all the things I have described. Anyone who wants to discuss this topic and prove that prospectors and independent farmers can't exist on the moon and tries to prove it by describing 1980 technology limitations will be ignored. If you can't see the effects of 100 years more of a ride on the technological exponential, you aren't worth my wasting time talking to. (If you have trouble, please try placing yourself in the year 1888 or 1838 and describing how the number of passengers per year in flight is a substantial fraction of the total population of the Earth in 1988. Using your 1888 or 1838 reference, describe the technology, economy and infrastructure that will support this. 1: Scientific American, Dec 1983, "Human Powered Vehicles" 2: Discussion on this net 2.5: I don't have the reference handy, but plants can grow in lunar soil, given water and some added microfauna. They do need protection from direct illumination, according to a comment from a biologist heard during the 2nd Lunar Base Symposium, so the shelters will need to hardened just like the people's shelter. Keep in mind that many plains farmers lived in dugout sod houses at least initially. So a bunch of neighbors get together and plow dirt over your new domes.

I also know how much a HARM missle costs, and I'd rather spend the money putting people into space.
