We're now just one Mercury year (88 days) from flyby #3, which happens on September 29, 2009, so this seems like a good time to start a thread about it.
http://messenger.jhuapl.edu/index.php For comparison purposes, it'd be nice if someone (probably someone on the Messenger team) put together a Mercury Map showing what areas will get better coverage from this flyby than from the previous ones. I realize it'll be very similar to flyby #1, but it won't be exactly the same. After that, it's a long wait until MOI on March 18, 2011. Curiously, that's the same date the New Horizons crosses the orbit of Uranus. http://pluto.jhuapl.edu/mission/passingpla...ets_current.php --Greg |

Just half an orbit away now. (Messenger's orbit is currently 116 days). Even if the coverage largely duplicates flyby #1, the phase angle might be different enough to be useful. Does anyone remember how close to the other flybys the Messenger team started posting information for the public?

Does anyone remember how close to the other flybys the Messenger team started posting information for the public? I dont recall for sure but if memory serves me right they published their flyby timeline very close to C/A, maybe 2 or 3 weeks in advance. The press-kit seems to have been published on 13 Sep 08 for the 06 oct 08 flyby Press Kit: MESSENGER Mercury Flyby 2 (PDF)
