Launched on August 3rd 2004, NASA's MESSENGER will become the first spacecraft to orbit Mercury.

News and updates are availbale via Johns Hopkins University MESSENGER website and the Kennedy Space Center's MESSENGER website.

There will be an earth flyby in August followed by a couple of swings by Venus and three velocity scrubbing passages past mecury before the craft enters orbit in March 2011.

http://www.space.com/astronotes/astronotes.html : Messenger fired its big engine successfully for almost 9 minutes on Dec. 12 -- the last component of the craft that hadn't been operated until then. So everything works (except for occasional software collywobbles). Now if everything will just continue working...

A thought from someone on another space list:

Will MESSENGER and Venus Express conduct any joint studies on Venus like Galileo and Cassini did with Jupiter in 2000? And if they can and do, what could they do together that they could not do alone?


--------------------
"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853

It might be possible during the June 2007 flyby; however, MESSENGER won't be collecting science data during the October 2006 flyby (due to solar conjunction), so that opportunity is out.

This is because Mercury transits the Sun on November 8 (19:14 UT) to November 9 (00:15 UT). And transits can only occur at inferior conjunction ie when Mercury anf Earth line up in a straight line anf Mercury is at "New moon" phase. Mercury is too close to the Earth for a month or so before and after the inferior conjunction for realiable transmission of data.
