Messenger's First Mercury Flyby Scheduled For Today

For those of you just tuning in, the NASA Messenger spacecraft will be doing its first flyby of Mercury today. It's the first spacecraft from Earth to visit Mercury since Mariner 10 in 1974.

I've been seeing contradictory reports about when the closest approach will take place; I've seen both "around noon" and "2:04 PM EST." If anyone has more accurate information, I'd appreciate it.

Messenger is supposed to settle into orbit around Mercury in 2011, but it's scheduled to make two more passes of the planet before then. I'm looking forward to the new science – and the new pictures!
