Messenger sent back an excellent photo of Mercury already.
link to much much much larger (1024x1024px) version
I first saw the image in a Wired News article. It had a link to the news release page for the spacecraft. Oh, and it was on today’s APOD (Astronomy Picture of the Day).
Personally, I think it is awesome. Perhaps we can exploit other planets just before we officially kill our own. Yeah, sarcasm is today’s theme.
At any rate, here’s linkage:
