Radau (crater) Crater on Mars

Radau is an impact crater in the Oxia Palus quadrangle of Mars, located 17.1° N and 4.8° W. It measures 114.5 kilometers in diameter and was named for Rodolphe Radau, a French astronomer (1835–1911). Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact.

Terrain softening Terrain with smoothly rpunded edges

The landscape polewards of around 30 degrees latitude on Mars has a distinctively different appearance to that nearer the equator, and is said to have undergone terrain softening. Softened terrain lacks the sharp ridge crests seen near the equator, and is instead smoothly rounded. This rounding is thought to be caused by high concentrations of water ice in soils. The term was coined in 1986 by Steve Squyres and Michael Carr from examining imagery from the Viking missions to Mars.
