For the first time, researchers have identified with certainty the banks of a dried-up lake on Mars. It covered 208 km, and its banks is an obvious place to look for signs of life. By Thomas AE Andersen June 22, 2009 at. 16:59
The lake is believed to have covered about 208 square kilometers and was down to 460 feet deep. Traces of the lakeshore include found in a wide delta area and in a series of high and gorges, which are believed to be deposits from the beach.
"This is the first direct evidence of a shoreline or lake shore on Mars. By finding and mapping the lake shore, we, together with the geological evidence could calculate the area and volume of the lake, which appears to be formed over 3.4 billion years ago, "said Gaetano 4f Di Achille.
The coastline was spotted in images taken by the spacecraft Mars Reconnaissance orbiters Hirise camera. The camera has a resolution so that it can see objects on the Martian surface with one meter resolution from its height of 320 km.
Analysis of the images shows that the water excavated a 45 mile long gorge which opens out into a valley where there are traces of deposits in a delta area, which suggests that the lake has been around a long time.
Scientists believe that Mars oldest surface created during the warm and wet period called Noachan of between 4.1 and 3.7 billion years ago. During this period, Mars also exposed to heavy meteor bombardment and widespread flooding. 4f
The lake has disappeared so quickly that there is created a low-lying lake shore. It is probably either evaporated or frozen 4f with ice, which slowly turned into water vapor and disappeared during a period of rapid climate change.
The surrounding deltas 4f are extremely interesting to scientists because such areas on Earth usually bury and preserve organic carbon compounds and other signs of life. The areas on Mars would be ideal candidates to search for traces of life.

There's no one forces you ... ;)
Why do you always nedgørre 4f other people who actually try to convey some info for all of us. If you can not bear to read an article with errors, read as some articles on the Danish Language Board or other place where people live to write really. Here at ing.dk we just need some knowledge about it is gramatisk properly, can it really be that big a problem, since there is a bother to comprehend the computer and write about such. space. then let the rest of us who can bear with small errors, read the articles and debates 4f them without all the noise I can send.

The engineer can learn from Science Illustrated. There is the amazing for proofreading 4f and communication - even in detail how the example probably would have called it "lakeshore" rather than "width" (which is ambiguous) and the like. Even punctuation is correct and there is total absence of the unit sloppiness 4f (mW, MW and whatnot), which ing.dk is bathed in.
Where in all the universe is the large amount of water gone. They can not just evaporate. On the ground caribou vapors the back down. Someone or something must have removed water quantities, they can not just move into space freed by gravity? The most obvious reason could well be a passing planet's major attraction that has absorbed water mass with them? Or, Mars væreret inhabited by (U) intelligent creatures who have fired all the water of as an energy source and then udøet? A visit on the planet may solve the mystery. Former settlements will leave the track. About water quantity contrast is aspirated from another planet will probably be more difficult to judge.

One is that Mars is quite small, and the heat from the decay of radioactive substances when to escape rapidly from the core. There is not as much pressure on vapor pressure that Mars may transpire water to the surface. 4f If the Earth's core temperature fell drastigt, the water and air sinking into the planet.
The second reason is also because the core temperature. There is no liquid iron inside Mars, and there has probably never been. Mars has no magnetic field to shield the solar wind, and every time Mars gets hit by a solar wind, slider, millions of tons of air (and water vapor) of the Martian atmosphere.
