The mapping of Venus refers to the process and results of human description of the geological features of the planet Venus. It involves surface radar images of Venus, construction of geological maps , and the identification of stratigraphic units , volumes of rock with a similar age.
A map of Venus compiled from data recorded by NASA's Pioneer Venus Orbiter spacecraft beginning in 1978. In 1978, NASA sent two Pioneer spacecraft to Venus. The Pioneer mission consisted of two components, launched separately: an orbiter and a multiprobe. The Pioneer Venus Multiprobe carried one large and three small atmospheric probes. The ...
Global topographic map of Venus, with all probe landings marked (red: returned images; with additional black dot: analyzed samples). There have been 46 space missions to the planet Venus (including gravity-assist flybys). Missions to Venus constitute part of the exploration of Venus.
An alternative explanation for the lack of satellites is the effect of strong solar tides, which can destabilize large satellites orbiting the inner terrestrial planets. [161] The orbital space of Venus has a dust ring-cloud, [167] with a suspected origin either from Venus–trailing asteroids, [168] interplanetary dust migrating in waves, or ...
The spacecraft's telecom system will be used to map gravity strength at Venus' surface, providing a uniform resolution of better than 160 km. [16] [23] The data will provide an estimate of Venus' core size and information about topographic features that lie underneath the planet's surface.
The following outline is provided as an overview of and topical guide to Venus: . Venus – second planet from the Sun, orbiting it every 224.7 Earth days. It has the longest rotation period (243 days) of any planet in the Solar System and rotates in the opposite direction to most other planets.
Because of Venus's retrograde rotation, the Sun would appear to rise in the west and set in the east. [9] An observer aloft in Venus's cloud tops, on the other hand, would circumnavigate the planet in about four Earth days and see a sky in which Earth and the Moon shine brightly (about magnitudes −6.6 [5] and −2.7, respectively) at ...
The European Space Agency has officially adopted two new space missions to study Venus from its ... The mission builds on ESA’s first spacecraft sent to map the planet’s atmosphere, Venus ...
