I'm trying to track down a map of Mars for a friend who remembers seeing it years ago but no longer has a copy. As best as I can tell from the description, it was one of the earliest global maps made, and so presumably published soon after Mariner 9; and it seems to have been projected in two hemispheric maps, one centered on 0° longitude and the other on 180° longitude. I expect that if anyone can remember such a map, it would be somebody here. Many thanks in advance for any assistance.

Almost certainly you are referring to the National Geographic Society's Mars map, very widely distributed and well known. It should be easy to find in a second-hand book store (they often have a few old NGS maps)., or through Ebay etc.

You could be right, but I actually have that map (February 1973) and it's projected in three hemispheres (centered on 120°, 0° and 240°) not two. So I was wondering if it might be something else.

Oh yeah! I forgot it was in three parts. When I get to my office tomorrow I will look through my maps and see if I can find another in two hemispheres. But now you point that out, I can't think of one now. The US Geological Survey, makers of most Mars maps, has not done one in two hemispheres, I am pretty sure. I think Edmund Scientific has a Mars map in two hemispheres, but it's much more recent.

While perhaps not quite what you are looking for, here is an
image of a Mars globe with Mariner 6 and 7 photos pasted
across it:

Phil:

Isn't there also a *really* old mappe of Phobos somewhere?

David, I can't find a Mariner 9 era Mars map in two hemispheres. I think it's possible the memory of the two hemispheres is a mistake.

Bob - why yes, I believe you're right. It was so early, Nostradamus must have had a hand in it.

Ecxellent work, Philhippus!

I just have one minor disappointment -- nowhere on the boundaries of your wonderful map do you tell us where there be dragons...

Phil:
The next camping time would be on the famous and giant Stickney crater of C-type (blackish carbonaceous chondrite). According to Phil's Phobos topography map in the Solarviews Web is that inside of Stikeyney crater might have an impresive view since the bottom floor is somewhat narrow (around 1-2 km) and the height of crater rims from the bottom should be of about 1.5km - 2km). Aren't correct these measures?

Yeah really old would be nice, like prior to the Stickney impact. I'd like to see that map.

And here are some maps of Barsoom:

I would rather have guessed freiherr Karl Friedrich Hieronymus von Münchhausen.

We've all seen the Stooke-O-Vision ™ exagerrated relief images of Mars (so much better than those old-fashioned Lovell-O-Gram © Lunar images) but now there's something better: 3-D 20x exagerrated relief *globes* of the Earth, Venus and Mars. The only problem is the cost: $600. Still, the Little Prince would be proud to live on such a body, and being an aristo he might have the cash to pay for it.

As they look exceptionally tactile, should they be described merely as being '3-D'? I toyed with names like 'Stooke-O-Fondle' but decided not to mention it, what with Phil's (ahem) 'enthusiasm' for Frankie Howerd and the like!

Bob, what Frankie and I get up to in our own time is no concern of yours.

But... interesting globes!

Phil

Posted by: Tayfun Öner Apr 9 2006, 06:19 PM

For a cost of about 10 globes you can buy a desktop milling machine and create your own 3d maps, here is my first model, Toutatis. What do you think Phil?

Posted by: Bob Shaw Apr 9 2006, 06:35 PM

It looks sorta... ...rude.

Bob Shaw

Posted by: Phil Stooke Apr 9 2006, 07:34 PM

A very nice model! I'd like to see more.

Phil

(Don't worry about Bob - he thinks everything is rude)

Someone has even made commercial asteroid models http://serradesignsinc.com/ast_models.htm

Posted by: Phil Stooke Apr 9 2006, 08:54 PM

Yes - but except for Eros, all are based on radar shape data, often very low resolution. Itokawa, for instance, is the pre-Hayabusa radar shape. It would be really nice to see models of Gaspra, Ida and Mathilde from shapes at the PDS Small bodies node.

I recall when you could by a large, accurate model of Phobos
for only $500. It looked like a big lump of coal to everyone else,
but you alone would know that you have a cool, expensive, and
accurate model of the largest moon of Mars.

Posted by: Tayfun Öner Apr 10 2006, 02:43 PM

Instead of millling the object itself, I will make moulds next time, if I can cast them successfully one copy for you Phil.

Posted by: Bob Shaw Apr 11 2006, 01:51 PM

Not old maps of Mars, but a convenient source of Lunar maps. These appear to be largely A3 prints off of .PDF files, but are nevertheless good value if A3 colour printing isn't your thing! I recently bought the 44 sheet LAC set and was well satisfied for the price.

I wonder whether there's anything similar on the Mars front?

I've written a few articles on mapping the planet Mars and its moons, Phobos & Deimos ... in fact Phil helped me out with some great MArtian Moons photos ... Contact me and I'll send You a .pdf version of those articles
