And MRO passed the milestone of data collected by all other Mars missions, great. Does this also include the rovers and Wiking missions?

I was wondering if there is a site that has an overview map of all past landing sites of the MERs and the Wikings, and maybe even the MERs' routes? Does Google have anything like Google Earth for Mars? I don't even know where Phoenix will land

If MRO has collected more data than the MGS and Mars Odyssey it is then almost the same as if it had collected more data than the rest combined. Mars Global Surveyor was a very successful mission.

There is Google Mars, a Martian equivalent of Google Maps. NASA's WorldWind has the option to view Mars in 3D. Neither of them have MGS or MRO imagery.

News: NASA Orbiter Provides Color Views of Mars Landing Site Candidates.
10/10/07
"Beginning this week, images will be released in color as well as black-and-white on the camera team's Web site. The colors are false color, not the way Mars would look to human eyes. The images are processed to maximize color differences, a technique useful for analyzing landscapes.
"Color data are proving very useful in interpreting geologic processes and history on Mars," McEwen said. "The images we're releasing today include views of some of the most interesting and compositionally diverse areas on the planet."
...
"Color is a boon to geologists who have been trying to discriminate different surface materials and their relation to the topography, McEwen said. "Color clearly identifies basic material distinctions like dust, sand or rocks, light-toned layered material, and frost or ice," he said. Color also helps geologists correlate layers in the Martian terrain. And scientists will be able to combine data from the high-resolution camera and the imaging spectrometer to make detailed maps of minerals and soil types on the planet."
http://www.jpl.nasa.gov/news/news-pr...lease=2007-116

This report is on false-color images to be released where color differences are exaggerated. But McEwens phrasing suggests he means his comments as a general statement about color imaging.

Really fascinating photos

BUT: Why do they come without a scale? Not very amusing! And this happens quite often. They are on a scale of 1:WHAT ?? Does anybody know?

They all come with the appropriate information if you care to look for it.

A 1:n value isn't appropriate for digital display ( as the dpi of screens is a variable)

http://hirise.lpl.arizona.edu/PSP_001546_2015 for example.

Map projected scale: 25 cm/pixel and north is up (bottom of the page)

Also - http://hirise-pds.lpl.arizona.edu/PD...ED.abrowse.jpg
Has a scale bar - as do many other images.

The rule of thumb is this.... if it's a 25cm/pixel image, then a 1280 x n pixel monitor shows 320 metres width at 100%.

Doug

Thank you. There seem to be exceptions, like

http://www.spaceflightnow.com/news/n0710/14mslsites/

I can´t find any information there. But, of course, you may be right that I have to browse the appropriate NASA pages

Great link !!! Thank you

I like Google Earth better than Google Maps, and i would like Google Mars more than Google Mars Maps so to say. But i guess it isn't available since you didn't mention it.

What about an overview map of the landing sites of all the rovers and the probes that have landed on Mars thoughout time?

New Views of Martian Moons

__________________
Everything I need to know I learned through Googling.

I don't know if it is just me, but we very rarely hear about Mars' moons. I would say they are very interesting since i believe they are just as closely related to the astroid family as any other astroid, so i think they should be studied some more - should be easier and cheaper since we can have spacecrafts both observe Mars and the two moons. But maybe the scientists think our spacecrafts don't get close enough to them - or maybe only a few people consider the moons as important for study as i do?

I think they are less worthy of study than the entire planet of Mars, which will be a distraction when ever you are near the Moons of Mars, but...

If we follow the idea of putting humans in orbit around Mars to have local control of a team of surface robots to do bigger faster work than distantly controlled robots could do, then it would make sense to build a structure under the surface of Phobos to house the people, and limit their long term exposure to the various radiations.

Later, when the telepresence robots have built a hotel with swimming pool, and a foundry and factory, we can send people to Mars itself.

Well, they're conveniently located to study along with Mars, so we'd learn more about small moons/asteroids.

No one's going to pay to send people almost all the way to Mars and then not land. Maybe after the first Mars manned mission is done, more likely the fourth or fifth, then an arrangement like that could garner some interest. But the landing will have to come first. It's just human nature, even if it's less efficient.

I understand what you are saying and respect it, but my opinion is the other way. I don't think people will pay to go all the way to the moon when going almost all the way can get the whole job done and cost 1/3 as much... but then again, you could be right. Time will tell.
