That said, I guess some of those 7000+ stored flyby commands could have been corrupted
by a CR incident, and we would not have discovered it until it came time to execute them.

Error correction both in uplink and memory make this quite unlikely.

Most safe mode entries have to do with loss of attitude reference. Flybys often provide opportunities for unexpected star camera problems from planetlight or occultations.

Here's a version of my map with the Flyby 3 sliver added in. This uses WAC and NAC images. I plan to add the Mariner map & radar data back in and then try adding one of VP's mosaics.

That's the latest,

I can understand Decepticon's father's request. With all this wonderful MESSENGER data, the Mariner 10 imagery seems... undesired.

Greetings all. I can appreciate and muse about various aspects of this request. I did a MESSENGER only map for Emily I think with the first 2 flybys. The MESSENGER site used to show their map without the Mariner, though they now have it added in. From what I've seen so far the Mariner 10 imagery is still of higher resolution near longitude 135W and near the South Pole, so a "best of all" map should maybe still have it in. I tend to keep a long term view of historical context perhaps. Nonetheless it's interesting to see what a MESSENGER only map looks like and it can of course be compared to the "both" map (also with radar).

Right now I happen to be in between two vacation trips, but I'll consider this in a bit. It might be fairly simple to add a switch that turns off the Mariner and radar imagery in my IDL procedure.

Catch you later,

Steve

The Mariner 10 data that really looks different is the south polar mosaic because it is a 1970s creation. Making a clean, modern version of it is on my to-do list.

apologies for resurrecting this old thread, but Science express had yesterday three new preprints on scientific results from M3 (as usual, full papers are available only to subscribers)
Evidence for Young Volcanism on Mercury from the Third MESSENGER Flyby
MESSENGER Observations of Extreme Loading and Unloading of Mercury’s Magnetic Tail
Mercury’s Complex Exosphere: Results from MESSENGER’s Third Flyby

I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.
