The Sands of Mars
Microscopic view of fine-grained materiel seen by Robotic Arm Camera aboard Phoenix Lander June 20, 2008
The Phoenix Lander has completed its first chemistry experiment. The soil is very close to what one would find in the dry valleys of Antarctica. Those valleys have similiar atmospheric conditions to Mars. Salts found include magnesium, sodium, pottasium and chloride; all nutrients that support life. The salts themselves are still more evidence of water. In many aspects of its mineralogy Mars is very much like Earth. We are amazingly close to discovering life on another planet.
