The NASA probe MESSENGER will pass by Mercury for the second time at 08:40 UT Monday (which is the middle of the night for the US). I'll get up first thing and write about what it saw, but it'll probably be a few hours before we get the really cool stuff. The last flyby was in January, and the pictures were incredible. As it happens, we'll be seeing the other side of Mercury in this second flyby, so it'll be all new territory (well, new to MESSENGER). Stay tuned! And check out Emily's blog for the in-depth info.
