Back by popular demand, Ordnance Survey have re-released this map of the Moon which was originally released for the 50th Anniversary of the Apollo 11 landing.

The Apollo 11 mission made made the 384,403km trip as part of the 'space race' with the USSR, and successfully touched down on 20 July 1969, at 20:17 UTC, making Neil Armstrong and Buzz Aldrin the first humans to land on the moon. Around 3.5 hours later, stepping on to the lunar surface, Armstrong said:

"That's one small step for [a] man, one giant leap for mankind."

Ordnance Survey have created this map of the moon using height data made available by NASA, captured by the Lunar Orbiter Laser Altimeter (LOLA) and the Kagyuga Terrain Camera and shaded to show the heights. The map covers a large section of the near surface of the moon, centred on the Apollo 11 landing site at the edge of Mare Tranquillitatis (Sea of Tranquillity). Larger, named craters are shown, along with the landing site itself - the crater names have been taken from the Gazetteer of Planetary Nomenclature. The area covered is 1350km by 1000km.

Ordnance Survey's Map of the Moon was originally released in 2019 to commemorate the anniversary of the Apollo 11 Anniversary.

In true OS style, the cartographer of the map left their "mark". Hidden in the map is their name. Can you find it?
