From: hpfcso!mll@hplabs.hpl.hp.com (Mark Luce) Subject: Milankovitch Cycles on Mars? Has anyone worked out the analogue to Earth's Milankovitch cycles on Mars? The Milankovitch cycles now seem to fairly well correlated to glacial cycles on Earth. See, e.g., "What Drives Glacial Cycles?", Scientific American, January 1990. The Milankovitch cycles result from the inter- action of three periodicities in Earth's orbital and rotational patterns: (1) the eccentricity of Earth's orbit, which varies with a period of 100,000 years; (2) the tilt of the Earth's spin axis, period of 41,000 years; and (3) the orientation of Earth's spin axis, period of 23,000 years. I presume that Mars also undergoes such orbital and rotational periodicities. Can anyone tell me what the periods are for Mars? Has anyone modelled this to see what the possible effects on Martian climate might be? I would think that in the past, when the Moon was closer to the Earth, that both the periods and amplitudes of the tilt and orientation of the Earth's spin axis would have been different. Any truth to this? Can anyone recommend any sources of information on this? ------------------------------ Date: 3 Mar 91 20:34:32 GMT From: zaphod.mps.ohio-state.edu!usc!jarthur!nntp-server.caltech.edu!tlynch@tut.cis.ohio-state.edu (Timothy W.

I figure many of you in the sci.space community follow the public policy end of things real closely, so I need a complete answer to the following. I am currently involved in a heated debate about the subject. As such, I won't tell you what side of the debate I'm on; I'll just pose the questions. Please reply by e-mail, I usually don't read this group. 1. Did Dan Quayle, who as VP chairs the National Space Council (right?), ever say something to the effect that Mars is a worthwhile goal becasue there is air and water there, and thus men could live there easily? 2. If so, can you give me a REFERENCE? If not, and you are in a good position to know something like that, could you tell me what position that might be? 3. If Question #1 is a MISINTERPRETATION of something Dan Quayle did say, could you also give me a REFERENCE and give me the interpretation you may have had of these remarks? I would appreciate any and all serious replies to these questions. If they turn out to be fire for my side of the debate, great. If not, then I will have learned something and will be happy to learn (though unhappy to debate :-) Thanks all, R.
