− | <p>I get lost on the farside. I know the surfaces of Mars, Venus and Titan better than our own Moon’s averted hemisphere. Part of the reason is that there are very few maps of the farside - I would love to have the farside equivalent of the [http://www.lpod.org/?m=20060416 <i>S&T Field Map of the Moon</i>], which I use every day. But there is probably not a big enough market to justify any company creating one, so I am making my own. The image above is a orientation map of the NE quadrant of the farside. I started with the US Geological Survey <i>Albedo Map of the Moon</i> (which they worked hard to display accurately the differences in brightness) and distorted it to so that both light and dark areas showed maximum detail. And then I added the names of a few craters and maria to provide some orientation. The Clementine mosaic has too high of lighting to show decently most craters so it will probably not be a basis for a map with all craters identified. Of course, it has already been the basis of the [http://www.lpod.org/archive/archive/2004/05/LPOD-2004-05-17.htm <i>Clementine Atlas of the Moon</i>] but that has a large enough scale - and accompanying shaded relief drawings - to make it possible to identify the craters. There are actually three other maps of the farside that include crater names. The revised National Geographic <i>The Earth’s Moon</i>, the USGS’ <i>Color-Coded Topography and Shaded Relief Map of the Lunar Near Side and Far Side Hemispheres</i>, and Rükl’s small hemispheric map on p 191 of his <i>Atlas of the Moon</i>. Perhaps when all the images from SMART-1 are mosaicked together an image map of the farside will be constructed and annotated with names - in the meantime I’ll make the other three farside quadrants.</p> | + | <p>I get lost on the farside.
