NASAs 'Curiosity' Search for Life Targets Water-Altered Rock
This rock's composition is unlike any other Opportunity has investigated during nine years on Mars -- higher in aluminum and silica, lower in calcium and iron. "Based on our current solar-array dust models, we intend to reach an area of 15 degrees northerly tilt before Opportunity's sixth Martian winter," said JPL's Scott Lever, mission manager. "Solander Point gives us that tilt and may allow us to move around quite a bit for winter science observations." Northerly tilt increases output from the rover's solar panels during southern-hemisphere winter. Daily sunshine for Opportunity will reach winter minimum in February 2014. The rover needs to be on a favorable slope well before then.

Kepler Mission To Find Earth-like Planets By Studying Planetary Transits
Earlier this week we spoke about finding Earth-like planets, and how hard it is to find them. We would like to see other planets similar to Earth, and we have a few absolutely necessary conditions: the planet must be rocky, solid, dense like Earth, a source of power like a Sun, chemicals resulted from volcanic activity, and liquid water. The most important thing however, is that the planet must be located in the Goldilocks zone, the area where the planet is not too far and not too close from a star. In order to find such planets NASA has begun the Kepler Mission which will last four year. The Kepler Mission consists of observing 100,000 Sun-like stars, and to be more accurate: scientists will study the so-called planetary transits. If you are not familiar with it then here is what this is: when a planet passes in front of its parent Sun as soon from Earth’s point of view, the brightness of the specific parent Sun decreases.
