  Mars
The southern hemisphere of Mars is predominantly ancient cratered highlands somewhat similar to the Moon.
Mars' thin atmosphere produces a greenhouse effect but it is only enough to raise the surface temperature by 5 degrees (K); much less than what we see on Venus and Earth.

 Mars - Wikipedia, the free encyclopedia
Mars has only a quarter the surface area of the Earth and only one-tenth the mass (though its surface area is approximately equal to that of the Earth's dry land because Mars lacks oceans).
The atmosphere on Mars is 95 percent carbon dioxide, 3 percent nitrogen, 1.6 percent argon, and traces of oxygen and water.
The datum for Mars is defined by the fourth-degree and fourth-order spherical harmonic gravity field, with the zero altitude defined by the 610.5 Pa (6.105 mbar) atmospheric pressure surface (approximately 0.6% of Earth's) at a temperature of 273.16 K. This pressure and temperature correspond to the triple point of water.

 Mars Express Links with Mars Exploration Rovers in Interplanetary Network Experiment   (Site not responding. Last check: 2007-10-19)
Because of the geometry of Mars Express' orbit and the location of the rovers during August, both the Spirit passes were 'Canister Mode' tests taken with Mars Express in the higher altitude in its orbital ellipse "to simulate data collection during an EDL event," says Arnold.
Although Mars Express and Opportunity had another 128 KBPS test 'date' August 10, that link-up was canceled by the MER team, because, says Arnold, of conflicting science and onboard power supply constraints.
As seamless and easy as these telecom link-ups between Mars Express and the rovers this month may sound, the tests that proved the protocol and the ability for a European mission and a NASA mission to successfully communicate with each other at Mars required years of groundwork on Earth.

By pitching the spacecraft at a rate faster than the spacecraft moves in its orbit around Mars, MOC is able to obtain pictures with a down-track resolution of about 50 cm/pixel (~20 inches/pixel), although the cross-track resolution remains ~1.5 m/pixel (5 ft/pixel).
These locations were determined by using sight lines from the landers to near and far objects seen in the pictures acquired by the landers, and then matching these to locations in earlier, 1.5 to 3.0 m/pixel MOC images.
