Ordnance Survey map of Mars

Ordnance Survey, Britain's official mapping agency, has made available for download a massive map of Mars in its classic style.

The planet Mars has become the latest subject in our long line of iconic OS paper maps. The one-off map, created using NASA open data and made to a 1:4,000,000 scale, is made to see if our style of mapping has potential for future Mars missions.

Sadly, they're not selling it in foldable print map form. They should!
