Any famous, obscure, touching, inspirational -- hell, ANY pro-space quotes would be welcome. Please EMAIL me any suggestions or quotes and attribute the source. I remember one about earth being the cradle, "but humanity cannot stay in the cradle forever" or something like that. Does anyone have the exact quote and the correct source? Can you think of others in a similar vein? Thanks in advance!! I'll post a summary of responses. - ERIC - Eric W.

Haun) Subject: Trying to build a fluxgate magnetometer -- help! I am trying to build a fluxgate magnetometer sensitive enough to monitor variations in the Earth's magnetic field, mostly to observe magnetic storms caused by big flares on the sun (March 13, 1989 stuff especially :-) !). I have seen an article about one of these designed to serve as a solid state compass in Radio Electronics magazine's "Hardware Hacker" column, and Radio Shack has also recently come out with a fluxgate compass. Would such a circuit be readily adaptable for my purposes? My main concern is whether it would have enough sensitivity; I would like to measure changes at least as small as 10 gammas (.001 Gauss), and if possible, even smaller. I envision having a setup with the magnetometer hooked up to a chart recorder and running 24 hours a day. It would alert me to the start of any magnetic storms and would show me the best times to try and observe the northern lights from my location here in California, if there are more *big* flares like this past March (they were actually seen here then, but I wasn't aware of it until a few days later). I would appreciate hearing from anyone who has built any sort of fluxgate magnetometer, anyone who has seen a construction article for one, or anybody with suggestions/ideas/etc. on the feasibility of this project. Please email to any of the addresses below. Thanks! -- ( Mark A.

Earth life *IS* contamination, everywhere but on the Earth. The other planets are Pristine, in that they have developed naturally, possibly independantly (though that idea is a bit up in the air with current theories about asteroids/comets), without an intelligence directing or interfering with their development. (And let's keep comments about possibly divine intervention from messing around with this forum.) Just because we like destroying our own world, does not give us the right to spread our short-sightedness to other worlds. Unless one lives by the `Might is right' philosophy, in which case I would definitely question their intelligence. >Just like right now we curse the names of Christopher Columbus, Ferdinand >Magellan, Andrew Carnegie, Henry Ford, and Leland Stanford. Those jerks! > :-) In many ways, these mew were jerks, in that the drive to succeed and discover was so strong, that absolutely no thought was given to the consequences of their actions, other than possibly their own glorification. However, I also believe that this is a failing of the human species, and not of any human in particular. Some are just more so than others. >This forum goes all over the world, folks.

The best thing we could ask for is to send our views to anyone and everyone to read, and to ask for views in kind to be returned. If you feel that something that you write would be misused, to your own detriment or to the detriment of others, then don't air it. If you have a desire to hide things from others, don't air it.
