Satellite Images of Mars

June 11th 2007 11:03
The variations in the martial landscape are striking: northern plains flattened by lava flows contrast with the southern highlands, pitted and cratered by ancient impacts. The surface of Mars as seen from Earth is thus divided into two kinds of areas. The paler plains covered with dust and sand rich in reddish iron oxides were once thought of as Martian 'continents' and given names like Arabia Terra (land of Arabia) or Amazonis Planitia (Amazonian plain). The dark features were thought to be seas, hence their names Mare Erythraeum, Mare Sirenum and Aurorae Sinus. The largest dark feature seen from Earth is Syrtis Major.


Olympus Mons (Mount Olympus), at 26 km is the highest known mountain in the solar system. It is an extinct volcano in the vast upland region Tharsis, which contains several other large volcanoes. It is over three times the height of Mt. Everest which in comparison only stands at 8.848 km.

Mars is also scarred by a number of impact craters: a total of 43,000 craters with a diameter of 5 km or greater have been found.

Below are various satellite images of the Martian surface, you can see more here.

Excuse me for nit picking, but I think it's misleading to tag these pictures as "satellite images". They are clearly artistic interpretations of the high quality data currently being beamed back by the HiRISE orbiter.

Well by definition an artificial satellite is any object which has been placed into orbit by human endeavor.
HiRise is aboard the Mars Reconnaissance Orbiter which has been orbiting Mars for 15 months.
The HiRise camera which takes these images consists of a 0.5 meter reflecting telescope similar to cameras on satellites orbiting Earth.
So images taken by HiRise are indeed "satellite images" as we are accustomed.

"satellite images as we are accustomed"? As we are accustomed? Either the photos are real or artistic interps. Which is it?

The photos are real of course, taken with a real camera.
I just don't understand what makes you think these satellite photos are different from satellite photos that we see of Earth?

Ok, so I should have worded my comment a bit more carefully. The problem I have with these "photos" is that the HiRISE camera shouldn't be able to take images like this at all. It's pointed directly down, and because it is designed to produce extremely high-resolution pictures, it's field of view is extremely narrow. In order to produce large panoramas like the ones shown here, you would have to painstakingly stitch hundreds of individual shots together to make the final product. This would be extremely time-consuming, and surely not an efficient use of the orbiters precious resources?

An example of typical images sent back are here:
Really Long Link

Not to mention the famous Victoria Crater shot:

actually if you notice the pictures HiRISE takes are 2D top down in nature, did you see the how flat the volcanos looked? They weren't taken at an angle, they were taken top down then shown at an angle.

The images above are just fancy versions of the imaes taken, I don't see how its decietful, just ads colour to the reality.

I just don't like the way Ian said that "the photos are real of course". They're not real photos.

the fact of the matter is. unless you work for any one who is actually taking photgraphs of mars no one can tell if they are real or not

Ahmed, these volcanoes are much wider than they are tall, which is why they look so flat.
