In a Mars exploration milestone, a laser remote sensing instrument on the Phoenix Mars lander has detected snow falling on the red planet. Data from the light detection and ranging (lidar) instrument—designed to gather information about interactions between the Martian atmosphere and ground surface—showed the snow falling from clouds about 4 kilometers (2.5 miles) above the spacecraft's landing site.
They are still looking at Mars because that's the closest "Planet" Everything else is way too far! For the moon,they're mostly done. There is no life on the Moon. It would'nt make a good Earth alternative! Mars is far and cold and so on.
