The Surface of Venus

We have a view from the Venera lander.

We have a topographic map by radar altimetry.

We have views made by the Magellan spacecraft made with radar.

Hear is a topographic map of (part of) Earth.

Here is a topographic map of Venus.

Here is what the surface looks like.
The orange color is because of Venus's atmosphere.

Venus has impact craters. Here is a a crater about 30 km in diameter.

The radar bright material is interpreted as the rocks ejected from the crater.

Here are three craters of about the same size.

Here is a crater that was broken by a fault.

Illumination is from the left.

Venus has volcanos.
Here for your amusement are some little "pancake" volcanos:

Here is one that looks like a tick.

Note the lava flow on the northwest.

Here is a big volcano, Sapas Mons showing extensive lava flows.

Here is a perspective view of the volcano Sif Mons. (Generated by computer using radar brightness and altitude data.) Here is another view .
