from the great group of people who brought you the wildly exciting, fun, and scientifically productive galaxy zoo, comes the new moon zoo!
using images from NASA's Lunar Reconnaissance Orbiter, you can explore the surface of the moon in great detail, helping to identify and describe craters so that scientists can learn more about the history of our moon.
from the website: "Craters can tell us more than just the history of the lunar surface though. In particular, you're asked in Moon Zoo to look for craters with boulders around the rim. Boulders are a sign that the impact was powerful enough that it excavated rock from beneath the regolith (the lunar 'soil') and so by keeping an eye out for these we can begin to map the depth of the regolith across the surface of the Moon."
enjoy the moon zoo!
