The Spirit has made important discovery on Mars

Spirit is an unfortunate robot that is stuck in the sand on Mars last year, but sedentary in their months has made a great discovery: evidence of subsurface water on the planet.

Recall that the Spirit ended its mission in 2004 and was embarked on an extra task, but in April 2009 was stuck in the sand. While he tried to leave, followed jammed and seven months after it broke a second round. Now is a scientist as stationary.

To take advantage of the situation, they let this young scientists introduced an underground conduit for sampling. The tests varied compositions found in the soil layers under the Spirit, insoluble materials near the surface and soluble below. This has led scientists to believe that there is water in the form of frozen or melted snow on the Martian surface.

Our friend is in hibernation while supporting the hard winter and as soon as possible (in March) shall operate its solar panels.
