The Moon - Lunar Orbiter 4

Flamsteed crater and ring in Oceanus Procellarum on the Moon

The Moon
Lunar Orbiter 4 image showing the 20 km Flamsteed crater on the Moon. Flamsteed is the large crater near the bottom of the image. A broken ring of bright ridges, probably the rim of an older crater nearly covered by the later Oceanus Procellarum mare basalts, can be seen. The ring is about 100 km in diameter, and a concentric wrinkle ridge is evident within the ring. The Surveyor 1 spacecraft landed in the upper portion of the ring. North is up.
