Did you know that it snows on Mars? In 2007 NASA sent a robotic spacecraft to Mars. It was called the Phoenix Mars Lander. In 2008, it photographed water-ice crystals falling over the north pole of the planet. Further research showed that the crystals only fall at night during the winter on Mars. The crystals do not land on the surface of the planet. The snow vaporizes while in the atmosphere.
