NASA maps the moon

You might not need a map to get to the moon, but you'd sure need one when you got there.

Looking to maybe one day land astronauts on the moon's south pole, NASA has mapped it with radar, according to NASA Science News.

That's a good thing, too, because that region of the moon has mountains as high as the Earth's Mt. McKinley and craters four times as deep as the Grand Canyon, said Doug Cooke of NASA's Exploration Systems Mission Directorate.

Now that NASA has high-resolution radar maps of the moon's south pole, folks can see an astronaut's-view movie on their home computers by visiting science.nasa.gov.
