past. 5. A very interesting image taken by the rover Curiosity is that of the Gale Crater area in which there is very fine sand, similar to or characteristic of a desert. The whole area is colored bright rust due to the presence of iron-rich minerals in its regolith. 6. The Curiosity rover, in one of its explorations, found a dry riverbed that showed flow channels for water, very similar to those found on Earth. This was a conclusion made by Sanjeev Gupta regarding the discovery of rounded pebbles on the dry streambed, as it indicated the action of water on the stones, making them rounded and smoothened. 7. The polar Martian surface is composed of several thin layers of water ice combined in many places with Martian dust. At the top of these layered deposits is the frozen water that is present year-round while additionally, frost enlarges the polar ice caps during its wintertime, made up mostly of solidified carbon dioxide from the atmosphere. This is due to the atmospheric process of lowered temperatures due to the planet's rotation in which its axis is tilted like that of the Earth, giving it the Martian seasons. Atmosphere temperatures can vary greatly, from plus 20 degrees C to minus 125 degrees C. 8. Scientists know that a meteorite which landed on Earth came from Mars based on the elements and isotopic compositions as analyzed in the laboratory and found to be very similar to those found on Mars based from the rocks and atmospheric gases analyzed by the previous fly-by missions and now confirmed by the rover missions on Mars. Of some 50,000 plus meteorites found on Earth, almost all of them are of Martian origin. 9. The Valles Marineris is a system of giant canyons and gullies formed by the geologic action of water many years ago but already completely dried up. This Martian landscape is a big rift valley about 5,000 km long, 100 km wide and 10 kms deep. 10. Manned missions to Mars
