Venus' Once Molten Surface
If you could look at Venus with radar eyes - this is what you might see. This computer reconstruction of the surface of Venus was created from data from the Magellan spacecraft. Magellan orbited Venus and used radar to map our neighboring planet's surface between 1990 and 1994.
Magellan found many interesting surface features, including the large circular domes, typically 25-kilometers across, that are depicted below. Volcanism is thought to have created the domes, although the precise mechanism remains unknown. Venus' surface is so hot and hostile that no surface probe has lasted more than a few minutes.

I was somewhat surprised, when reading about exploration of Venus, to find that the USSR had landed 10 probes on the surface, including one that worked for 2 hours. They did chemical and meteorological research and returned a bunch of pictures of the surface.

ReplyDeleteTemperatura di Venere: 460ºC, punto di fusione della lava: 600ºC, punto di fusione dell'alluminio: 660,3ºC. I falsi colori ingannano! Nell'immagine non è magma quello che si vede.
