Model of crustal plateau and tessera terrain formation via mantle downwelling after Gilmore (1998). Venus In situ Composition Investigations ( VICI ) is a concept lander mission to Venus in order to answer long-standing questions about its origins and evolution, and provide new insights needed to understand terrestrial planet formation ...
The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.
Venus to scale among the Inner Solar System planetary-mass objects, arranged by the order of their orbits outward from the Sun (from left: Mercury, Venus, Earth, the Moon, Mars and Ceres) Venus is one of the four terrestrial planets in the Solar System, meaning that it is a rocky body like
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
The body structure of these animals is a thin-walled, cylindrical, vase-shaped tube with a large central atrium. The body is composed entirely of silica in the form of 6-pointed siliceous spicules, which is why they are commonly known as glass sponges. The spicules are composed of three perpendicular rays, giving them six points.
SAR images provide the highest resolution data set. Microwave radiation is used to penetrate the thick atmosphere and map the surface of Venus. The SAR images are black and white images, which show the surface features using the intensity of radar return (echo), either due to surface roughness or orientation. [7]

Depending on the angle of impact, velocity, size, and strength of the approaching body, the atmosphere may tear and crush the projectile, essentially melting it in the air. This is an important observation for studies of the surface of Venus, as crater are used to determine relative ages and to approximate absolute ages of surface features. [13]
