Mystery cache not at the posted coordinates. Solve this puzzle about the 'man on the moon'.
The moon is utterly familiar. We see it all the time, in the blue sky during the day, among the stars and planets at night. Every child knows the outlines of the moon's lava seas: they trace the Man in the Moon or, sometimes, a Rabbit.
Naming
Mare Tranquillitatis was named in 1651 by astronomers Francesco Grimaldi and Giovanni Battista Riccioli in their lunar map Almagestum novum. Earlier lunar cartographers had given the feature different names. Michael van Langren's 1645 map calls it "Mare Belgicum" (Latin for the Belgic Sea), the classical name of the North Sea And Johannes Hevelius included it within Pontus Euxinus (after the classical name for the Black Sea) in his 1647 map.
Landings

In February 1965, the Ranger 8 spacecraft was deliberately crashed into the Mare Tranquillitatis, after successfully transmitting 7,137 close-range photographs of the Moon in the final 23 minutes of its mission.
Surveyor 5 landed in Mare Tranquillitatis on September 11, 1967, and was the fifth lunar lander of the uncrewed Surveyor program.
Apollo
This mare was also the landing site for the first crewed landing on the Moon on July 20, 1969, at 20:18 UTC. After astronauts Neil Armstrong and Buzz Aldrin made a smooth touchdown in the Apollo 11 Lunar Module named Eagle, Armstrong told flight controllers on Earth, "Houston, Tranquility Base here. The Eagle has landed." The landing area at 0.8° N, 23.5° E has been designated Statio Tranquillitatis after Armstrong's name for it, and three small craters to the north of the base have been named Aldrin, Collins, and Armstrong in honor of the Apollo 11 crew.
