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.

The March 16 edition of LPOD has an image of the SMART-1
impact region from Lunar Orbiter 4:

http://www.lpod.org/?m=20060316

Interesting quote:

"The good news is that SMART-1 has captured thousands of images of the Moon; the bad news is that because of the daily pressures of flying the mission the team will not have time to start archiving the images and release then until after the impact. Apparently many of the images have not been looked at by anyone!"


--------------------
"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

Now, why doesn't that excuse work for, say, MSSS? Well, I guess SMART-1 doesn't have a "People's Camera" installed. biggrin.gif

Pah! We'd have looked at them if they'd let us...

Somehow, they get away with that excuse across the whole of ESA.

As a taxpayer who funds an admittedly minuscle component of this I am embarassed. The science is good and theadministration is defensible but the public outreach is abysmal.
Oh well - time to ping my MEP yet again.

What we need is Esawatch - I'm not a Cowing fan, but at least he asks the awkward questions from time to time.

Do you really think an "ESAWatch" would work in Europe, given that U.S. "democracy" materially differs from European "democracy"? We (the U.S.) have our faults, as Europeans are more than willing to point out, but there are some ideas that work here that, in my opinion, wouldn't be easily transplantable to Europe. That said, I would love to see someone give ESA a dose of the "Cowing treatment," even if only for the sake of Schadenfreude.

I'm not optimistic about the results; I'm no expert, but has *any* impacting spacecraft or spent booster on the Moon generated a confirmed flash or ejecta sighting from Earth?

Master Betty: Nyah. Haha. It is EVIL, it is so EVIL. It is a bad, bad plan, which will hurt many... people... who are good. I think it's great that it's so bad.

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.
