Fra Mauro
Apollo 14 · February 1971 · on the Moon, 3.65° S, 17.47° W
Hilly ground thrown out by the impact that made the Imbrium basin. Alan Shepard hit two golf balls here.
What is there
Apollo 14 descent stage (Lunar Module, NASA)
The bottom half of the Apollo 14 Lunar Module, still standing where it landed: it served as the launch pad for the top half, which carried the crew back up to the Command Module in orbit.
Apollo 14 flag (Flag, NASA)
Still standing: Lunar Reconnaissance Orbiter photos show its shadow moving as the Sun moves. A horizontal rod along the top holds it out, since there is no wind. Its colours have most likely bleached white in the sunlight.
Apollo 14 ALSEP central station (Experiment, NASA)
The hub of the Apollo Lunar Surface Experiments Package: it gathered every experiment's data and radioed it to Earth, under its sunshield, through the antenna on its mast. The stations sent data for up to eight years, until NASA switched them all off in September 1977.
Apollo 14 nuclear power generator (Experiment, NASA)
A SNAP-27 radioisotope generator: plutonium-238 heats it and its fins (around 400 °C) turn the heat into about 70 watts of electricity, day and night, for the experiments. Its fuel has been decaying since; it still gives off a little heat.
Apollo 14 passive seismometer (Experiment, NASA)
It listened for moonquakes, meteorite impacts and the crashes of spent rocket stages, under a silver blanket spread out to keep its temperature steady. Together the Apollo seismometers found the Moon rings like a bell for an hour after a hit, and revealed its crust, mantle and small core.
Apollo 14 ion detector (Experiment, NASA)
The suprathermal ion detector counted charged particles around the Moon: from the solar wind, from the Earth's magnetic tail when the Moon passes through it, and from gas the astronauts' equipment released.
Apollo 14 charged particle detector (Experiment, NASA)
It measured electrons and protons arriving from the Sun and from the Earth's magnetic tail.
Apollo 14 laser retroreflector (Experiment, NASA)
100 corner-cube prisms that send light straight back where it came from. Observatories on Earth still fire lasers at it today and time the echo: the Moon's distance to a few millimetres — it is moving away from us 3.8 cm a year.
Stand at Fra Mauro in Stellingo: the ground is shaped from orbiter elevation maps and photos, the hardware is placed where it really is, and the sky above — the Sun, the Earth, the stars — is the real one, at any date you choose.
