Water on Mercury?

NASA writes:

New observations by the MESSENGER [sic] spacecraft provide compelling support for the long-held hypothesis that Mercury harbors abundant water ice and other frozen volatile materials in its permanently shadowed polar craters.

Just as Jason SIlva says, this really is the first time in human history where we don't need time-lapse photography to witness the advancement of our species.

What's next? Sean Solomon, principal investigator of the Messenger mission explains:

"But the new observations have also raised new questions," adds Solomon. "Do the dark materials in the polar deposits consist mostly of organic compounds? What kind of chemical reactions has that material experienced? Are there any regions on or within Mercury that might have both liquid water and organic compounds? Only with the continued exploration of Mercury can we hope to make progress on these new questions."
