Chandrayaan Lunar Mission Will Carry NASA Payload
http://www.spacedaily.com/reports/Chandray...SA_Payload.html Bangalore, India (SPX) May 1, 2006 - ISRO has agreed to carry two NASA research instruments aboard its Chandrayaan-1 spacecraft, the Indian lunar-orbiting mission planned for launch next year, The Hindu newspaper reported Sunday. ISRO Pushing For Indian Satellite Industry http://www.spacedaily.com/reports/ISRO_Pus...e_Industry.html Bangalore, India (SPX) May 1, 2006 - ISRO is looking to jump-start an Indian satellite industry by inviting prospective domestic contractors to work with the agency until they can develop independent manufacturing capabilities. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Back to the summer issue. I think that what is intended is this: the spacecraft's orbit plane right now is roughly aligned with the sun - i.e. the sun is now in or close to the orbit plane, so the spacecraft fies over the sub-solar longitude on every orbit. Three months from now the orbit will be over the terminators, which will give a lot less heating from the ground. Six months from now, it will be passing over the sub-solar longitude again. Put another way, the orbit plane is fixed in space. It's not like Mars Odyssey etc., crossing the equator at a fixed time of day on every orbit, which requires the orbit plane to rotate during a Mars year.
But summer this is not! Phil -------------------- ... because the Solar System ain't gonna map itself.

...the sun is now in or close to the orbit plane... Isn't that what I said in post #279? At any rate, does anyone know what the current orbital geometry really is? For some situations beta=90 (constantly over the terminator) could be the worst case, since it will always get solar input on the same side. beta=0 is stressing for lunar IR. -------------------- Disclaimer: This post is based on public information only.
