Map of the route of the rover Curiosity in the first 43 days of sunshine on Mars ...

This map shows the route of the NASA rovers Curiosity in the first 43 Martian solar days (called solami) on the planet Mars (solar day on Mars is almost equal to the earth - 24 h 39 min) during the execution of the mission on Mars (September 19, 2012)...

The route starts from the contact with the surface of Mars rover, that is from the landing site, later known as the landing site Bradbury (in honor of the American science fiction writer Ray Bradbury, who passed away recently). 

Announced a new contender for the title of the second Earth

A new contender for the title of the second Earth entered the list of exoplanets that might harbor life on its surface. The new super-Earths Gliese 163c is on the inner edge habitable zone of the red dwarf Gliese 163 ( Gliese 163 ) and is likely to have liquid water on the surface.

Super-Earths defense of life is weaker than on Earth

Life may exist on the "super-Earths" with a small probability, than on the small-sized planets like the Earth, because they do not have a magnetic field and volcanic centers, necessary for life.

Media writing, based on the statement of the group planetologists Vlada Stamenkovic of the U.S. Massachusetts tehnoinstituta that the purpose of the study - the ability to find out, whether considered "super-Earths" enlarged copies of the earth with the same properties, or they are very fundamentally different from it.
