Ski Mars!
Explanation: These brightly reflecting fields of snow or frost are on the slopes of a crater rim in the northern hemisphere of Mars . They are 500 meters or so long and have lasted through about eight months of the Red Planet's spring and summer weather . Recently imaged by the Mars Global Surveyor spacecraft , they also seem to be relatively uncrowded ... suggesting to some on April 1st , that lift tickets on Mars are extremely expensive. Of course, a vacation on the Red Planet could still offer some advantages to skiing and snowboarding enthusiasts. For example , Mars' low gravity - only about 3/8ths Earth's gravity - would definitely tend to reduce sore muscles and fall-related injuries. Happy April Fools day from APOD .
