Many Moon Maps

National Geographic’s 1969 map of the Moon

With the 50th anniversary of Apollo 11 almost upon us, there’s been an uptick in moon-related content, which includes moon-related map content. For example:

New Exhibition. Opening today at The Map House in London, The Mapping of the Moon: 1669-1969, an exhibition of three centuries of lunar cartography. “The exhibition includes rare early 17th and 18th Century observations of the moon from astronomers such as Athanasius Kircher and Jean-Dominique Cassini, important maps produced by NASA for lunar exploration, globes and signed material by astronauts Neil Armstrong, Buzz Aldrin, Alan Bean and Jim Lovell.” Runs until 21 July.

New Map. The July 2019 issue of National Geographic has a new map of the Moon that updates the 1969 painted version (see above) with a mosaic based on Lunar Reconnaissance Orbiter imagery. I don’t know whether that means a physical version of the map will be included with the issue as an insert, but I hope it does.

New Way to Navigate. NASA has a post on using GPS on the Moon. Now, I’d thought that using GPS on another world would require the deployment of a GPS satellite constellation around said world. No, this is about using Earth-orbiting GPS signals for lunar navigation, which simulations suggest is possible. The mind boggles.

Equal Earth Gets a Wall Map

It was announced today at NACIS that the Equal Earth projection is now available as a wall map—which is a necessary thing if it’s going to go toe-to-toe with the Peters map. The political wall map is only available as a download (three versions, centred on Africa and Europe, the Americas, or the Pacific): the 19,250 × 10,150-pixel, 350 dpi file results in a 1.4 × 0.74 m (55″ × 29″) print—assuming you have access to a large-format plotter. Not everyone does, so it’s only a matter of time, I suspect, before they have prints available for sale.

The map shows countries and territories in surprising detail (it includes Clipperton, for example); and while it does show disputed regions as such, its choices of boundaries and nomenclature won’t make it many fans in South Korea or India.
