The Dark Side of the Moon Topographic Map

The Dark Side of the Moon Topographic Map

And if the dam breaks open many years too soon
And if there is no room upon the hill
And if your head explodes with dark forebodings too
I’ll see you on the dark side of the moon

Well, if we ever do meet on the dark side of the moon, I think I would like to take the topographical map recently created by the LRO spacecraft. The Global Lunar DTM 100 m topographic model (GLD100, for short) shows the hidden side of the moon in enough detail to plan a good landing or at least give a great appreciation of our only satellite’s backwards face.

The image was created using a pixel scale of about 75 meters, and was created using the differences in stereo images taken via two Narrow Angle Cameras (NAC) and a WAC. The map used over 69,000 WAC stereo models, and it covers the moon from 79 degrees south to 79 degrees north, or 98.2% of the entire lunar surface. In other words, more than enough detail to avoid getting lost on the dark side of the moon.
