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. Phil -------------------- ... because the Solar System ain't gonna map itself.

Given the low impact speed, this is *not* a hypervelocity impact. Metal and rock debris leaving the impact crater at high velocity will be hot, but probably barely hot enough to glow thermally at visual wavelengths. <I'd like to see a calculation on the maximum kinetic heating possible> There should be some visible flash from remaining hydrazine and maybe shorting batteries and the like.. hard to guess how much.
I'd think a flash would be much more visible at thermal infrared wavelengths.. 5 micrometer or longer. Having an acutal flash dection will pinpoint the impact point better than raw spacecraft L.O.S. timing, I'd presume, and provide a good coordinate for future high and eventually ultra-high imaging. |
