Moon Model

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 265.9 Hz, 28 cents sharp of C4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap to land a lunar module; tap again to pack up and lift off. Pick the flag in the Splash tab.

The Moon is the Earth's only natural satellite, a gray world of craters about a quarter as wide as the Earth. Its dark patches are wide plains of old, cooled lava. Its gravity is about one sixth of the Earth's, so things weigh much less there.

Tap it and a lunar module lands, an astronaut climbs down, bounds over in low-gravity hops and plants a flag, which you can pick in the Splash tab. Tap again and the astronaut packs up and lifts off. Between 1969 and 1972, twelve astronauts walked on the Moon.

Made in Splashery. Its code is MIT.
