The Dark Side of the Moon

I guess everyone would prefer to see the Rainbow side of the Moon or a glance of the bright side of the small asteroid. Nevertheless ESA got what it can be called a perfect shot of the Dark Side of the Moon where no human telescopic eye can normally reach.

ESA launched a SMART-1 mission which brought us images of Plaskett, Rozhdestvenskiy and Hermitethe, the 3 big craters which stand always hide on the darker side, each one with a surprising size of more than 100 Km wide.

The LUNA INCOGNITA or the undercover side of the Moon can be yearly seen, for a few days, due the Earth's rotation process but never as it was now caught, really closer to our sights.

Who knows if it isn't the right place to simulate a human mission to Mars, without the fear of the distance and the danger of not being able to get back if something doesn't come out according with the plans. Credits: ESA

Saturn MOON ENCELATUS - A Distante Frozen World

Credits: NASA spacecraft CASSINI
CASSINI the unmanned spacecraft launched in 1997 to orbit planet SATURN and its multiple MOONS has arrived, 7 years later, to Saturn system in 2004. 
Since then, Saturn and its many natural satellites have been studied and observed as well as their heliosphere, testing the famous Einstein theory of relativity.

On its way, Cassini captured this still and partially sunlit ENCELADUS, a Saturnian MOON covered in ice that reflects sunlight similar to freshly fallen snow, making ENCELADUS one of the most reflective objects in the solar system. The blue color in this false-color image indicates larger-than-average ice particles. The moon's surface is decorated with fractures, folds and ridges caused by tectonic stresses. 

The image was taken with the Cassini spacecraft narrow-angle camera on April 7, 2010, using filters sensitive to ultraviolet, visible and infrared light.
