American (robots) explore Mars

Who took Opportunity, standing on the Cape Cape Verde (Cape Verde)? No one. This rover itself made a picture of rock ledge in the kilometer crater of Victoria by the Bay Ducks (Duck Bay), and mission specialists built into the frame of the rover to get an idea of ??scale. Because Opportunity is now really makes a detour to circle huge crater (Figure NASA / JPL / Cornell).

After all, how great it is — to see Mars through the eyes of a little robot, patiently carries cold and harsh winds, sandy planet! And even more interesting to imagine how this looked like the landscape in a time when there was a different climate — more humid.

Mars rover Opportunity (mission Mars exploration rover) found at the edge of Victoria Crater (Victoria) a lot of big «blueberries» — that scientists have named a specific Martian mineral resembling its appearance small berries. This finding raises new questions about the history of water on Mars.

Blueberries on Mars, scientists have discovered a couple of years ago and had already lined up version of their origin, associated with ground water. Now planetary scientists believe that these small spheres are formed in the thickness of the Martian soil containing iron minerals at a time when rising groundwater. Thus, the distribution and location of the found blueberries can talk about periods of increasing and decreasing water levels at the site of the planet

Opportunity in the workplace, these spheres have been seen almost everywhere: they were scattered around the landing site and staff throughout the seven-mile path of the rover to Victoria. However, with increasing distance from the landing site where they occur less frequently and are much smaller in size so that the diameter instead of 5 mm is already 1 mm or less.

«Juicy blueberry,» Dr. Squires admired (Photo NASA / JPL-Caltech / Cornell / USGS).

However, as soon as the rover approached the edge of the crater, the trend was reversed. The landscape was once again «full of big juicy blueberries,» — said at a conference of the American Geophysical Society (AGU Fall 2006) Dr. Steve Squires (Steve Squyres) from Cornell University (Cornell University), a leading scientist of the mission Mars exploration rover, adding: «We were surprised «.

It should be noted that the plain Meridiani Planum, which crossed the Opportunity, has a small slope, and the little robot gradually upwards, moving to a huge crater, Victoria.

Therefore, researchers believe, the rover, and found fewer and fewer blueberries to the extent that it raised «above sea level.» Beat the same meteorite that created once Victoria has exposed deeper layers of the plains, which were hidden in the numerous and large blueberries. They were thrown out blow to the surface.

It turns out that in the Victoria Ground water once rose from the depths, creating a blueberry, but not at the same time reaching the surface.
