Planetary maps

Vibrant planetary maps, via The Telegraph.

A geologic map of Mars viewed from above the northern polar ice cap, based on surveys from the Viking orbiter spacecrafts. Colours depict rock type (lithology), rock layers (stratigraphy) and structure.

Geologic map of the moon based on data collected from the Lunar orbiter, Mariner 10 and Zond 7 spacecraft. The upper half of is the near-Earth side and the lower half is the far side of the moon. The lunar south pole does not receive as much sunlight as the lunar north pole. It is thought that permanently unlit craters in this region may hold water ice.

Map of Ganymede, Jupiter's largest moon, based on data from the Voyager spacecraft. Ganymede's surface is composed of water-ice and rock mixed with ice. The surface features dark regions covered with impact craters and lighter regions criss-crossed by grooves and ridges. It is thought a saltwater liquid ocean exists beneath the surface.

A map of part of the northern hemisphere of Venus, based mainly on radar data from the Russian Venera 15 and 16 orbiters as well as data from the Pioneer Venus orbiter and Earth-based radar telescopes. Colours correspond to surface features, including volcanoes (light red and pink), mountains and ridges (purple, green and blue) and plains (yellow and light green).

Geologic map of Mars viewed from above the south polar ice cap, based on surveys from the Viking orbiter spacecrafts. The southern ice cap is a permanent feature, composed of water ice and frozen carbon dioxide. Its size shrinks during the Martian summer.
