Emily posted a very nice article in her blog on the SMART-1 lunar impact in September this year. Here's a map of the targeted point:
But as Emily explained, the actual point may be off because of uncertainties about topography. I'm starting this thread to have a place for news and opinions on it, and - I really hope - maybe some observations at the time from any amateur astronomers out there. This event will be the last event to make it into my atlas. I've left a space for it, and I will make the final maps and fit them in, and then send the stuff off to the publisher.

A very good question.
There is general agreement, I believe, that the Hiten impact on 10 April 1993 was visible, in fact imaged in IR (Google will lead you to the image). Like SMART-1 it was in darkness near the terminator on the near side. There were poorly documented reports that Luna 2's impact was observed (Sky & Tel. Nov 1960 p. 265). Similarly Luna 5's upper stage rocket (New Scientist, soon after impact, but I don't have the reference yet), and Luna 7 (unpublished MSC internal report in LPI library). Most western observers discounted these reports, and strenuous efforts to view the Ranger impacts came to nothing. But modern CCD and IR imaging should do much better. I personally have little doubt that SMART-1 is at the very least worth making an effort to see, and in fact will probably be imaged.

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 |
