Snowfall on Mars

Can it get better than this? The US National Aeronautics and Space Administration (NASA) reported yesterday that instruments on Mars have detected snow falling.

WASHINGTON — NASA’s Phoenix Mars Lander has detected snow falling from Martian clouds. Spacecraft soil tests experiments also have provided evidence of past interaction between minerals and liquid water, processes that occur on Earth.

A laser instrument designed to gather knowledge of how the atmosphere and surface interact on Mars, detected snow from clouds about 2.5 miles above the spacecraft’s landing site. Data show the snow vaporizing before reaching the ground.
