JTC-1702

Mare Tranquillitatis

11.30° N, 33.50° E

In the northern reach of the Sea of Tranquility, where the basalt runs unusually rich in titanium and reads a shade bluer than its neighbours.

A steady target all month. The Sea of Tranquility is the easiest dark patch to point out to a beginner.

On the dark basalt seas. The easiest ground to find from your own backyard.

Its place on the near side

The Moon keeps one face turned toward Earth, so your crater is fixed in the same spot of sky every clear night of your life.

JTC-1702 lies at 11.30° N, 33.50° E, in Mare Tranquillitatis. On the map, north is up and east is to the right, exactly as it appears through a telescope from the high desert.
