The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) [1] that preserves geologic structures for long periods of time.
The global surface of Venus was first mapped by the Magellan orbiter during 1990–1991 with 50 km spatial and 100 m vertical resolution. During three orbit regimes, the surface images were transmitted back to the Earth. These three orbiting motions of the spacecraft are called mapping cycle 1, 2 and 3.
The very first visible-light images of Venus' surface from space have been captured by NASA's Parker Solar Probe, and it could help researchers piece together the mysteries of the distant planet.
Color-coded elevation map, showing the elevated terrae "continents" in yellow and minor features of Venus. The Venusian surface was a subject of speculation until some of its secrets were revealed by probes in the 20th century. Venera landers in 1975 and 1982 returned images of a surface covered in sediment and relatively angular rocks. [36]
Venera 9 provided the first images of the surface of Venus as well as more gamma-ray analysis. [17] By sending the first images of Venus' surface back to Earth the Venera missions provided scientists with the ability to relay the achievements with the public.
Locating volcanoes on Venus became possible during the Magellan mission in 1990, which mapped over 95% of the surface of Venus. [32] The surface of Venus is hidden by clouds but surface features can be mapped using synthetic aperture radar. [33] Some images created by this mapping can give a perspective view of the elevation of the surface of ...
Surface of Venus from Venera 13. In 1982, the Soviet Venera 13 sent the first colour image of Venus's surface, revealing an orange-brown flat bedrock surface covered with loose regolith and small flat thin angular rocks, [45] and analysed the X-ray fluorescence of an excavated soil sample. The probe operated for a record 127 minutes on the ...
