Scientists are watching the strange cloud above the surface of Mars
For more than a month, a spacecraft of the European Space Agency oversees the odd cloud, like a plume, are located above the surface of the Red Planet. Scientists say that the cloud does not change the location from September 13 - it is always on top of the mountain Arsiya (former volcano), which is near the equator of the planet. However, as the researchers note of the ESA, it is just a coincidence. The reason for the formation of clouds is not volcanic activity, since according to planetary scientists, it is stopped on the red planet 50 million years ago. Then, what is it?
The site of the European Space Agency announced that the same orbital space probe (it is the Mars Express), as well as his predecessors have already noted the presence of similar clouds at least three times. In this case, the cloud appeared above the surface at the same time of the Martian year. And this is no coincidence, according to the ESA.

The cloud contains an aqueous ice continues to explain ESA and scientists believe formed by the movement of air masses along the old Mars volcano. The researchers believe that the observed object is the result of orographic clouds - effects associated with overcoming air masses elevations of the mountain relief, which resulted in the formation of various forms of lens-shaped clouds. When crossing ridge airflow downwind generated wave. In updrafts clouds are formed, and gaps are formed cloudless downdrafts.

This cloud image was acquired on September 21
Scientists watching the cloud, note that it increases in the Martian morning hours, more stretched along the equator. It is possible that on the dimensions of the cloud also affects the dust is still present in the Martian atmosphere and the rest with the last global Martian dust storm, because of which, by the way, most likely died rover "Opportunity" space agency NASA. According to latest information, the people involved in the mission of the rover, do not feed the hopes of his recovery.
