I will go on record saying that I don't believe in Skinakas.

Whatever Phil. Next thing you know, you'll be telling us the Spagetti Monster isn't real.

Why do people see vague, dark, circular albedo markings and immediately jump to large impact basin... rolleyes.gif

Yes, Ted, I use them to make cootie-catchers...


After this discussion I couldn't resist trying my hand at making a fold-up version of Phil's nice composite -- my first attempt at such, using a perl script from here...

In case anyone is interested, the results look like this:

So that, should they get lucky, they can claim the discovery.

As the first encounter is getting near, I plan to make a 4K map of Mariner 10 mosaics available so that we can make a better map together as above, what do you say?

Yes, this is a good idea. It will be interesting to see the maps evolve from just Mariner 10 through each of the Messenger flybys, to the final orbital phase.

We're going to see a brand new planet when those first Messenger images come in.


Yeah, I think that's a truism based on experience. Seems like our initial flybys almost invariably miss the most interesting features of a given target for whatever reason...

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Hi,

Ok, here's the familiar Mercury map with a color/albedo overlay from two Mariner 10 images made from different filters. Colors are approximate and perhaps a little to saturated but it's a start.

Here it is. Some notes about the map: It was constructed by me from the mosaics created for the Atlas of Mercury by NASA, (thanks to NSSDC for supplying the digital data). Becuse of discrepancies in the original mosaics this map may have errors as large as a few degrees. The original is 12K but only 4K fits to the 1MB limit here. With other regions added we may have to compress it more.

It is in simple cylindrical projection with 0 degrees longitude at the center. Some of the missing parts are the missing parts of the mosaics which are possible to fill with Mariner 10 data. First I think we should do this. And please add the radar data last as they have North-South ambiguity.

Here's a map of Mercury that I've been using for a couple of months now, I've added some radar information that's available on the web.

This map includes recent (reported within last 2 wks) amateur imaging (290-360 deg) by John Boudreau and our SOAR telescope imaging from earlier in the yr (185-290 deg), only to +-70 deg lat shown however. Alignment along longitudes of bright features (all rayed radar craters) is an artifact of the phase correction. Agreement with rayed radar craters and their diameters is given in our paper.

Welcome Gerald. Thanks for the links to your paper.
