The Russians sent 10 probes there between 1967 (Venera 4) and 1983 (Venera 15).
Venus has an atmospheric pressure about 91 times greater than Earth's due to its dense carbon dioxide atmosphere and the high surface pressure caused by the greenhouse effect. This extreme pressure makes Venus's surface conditions inhospitable for life as we know it.
No, Venus does not have a hydrosphere. The extreme temperatures and atmospheric conditions on Venus make it unable to support liquid water on its surface.
The surface conditions on Venus are thought to be too severe to support even simple lifeforms.
There is no known evidence of liquid water every having existed on Venus, but it is quite possible that surface conditions were once very different from what they are now. Note that the surface of Venus has not been studied as extensivley as the surface of Mars.
The atmosphere of Venus is not breathable by any life form that we know of. Our probes survive less than a minute on the surface.
Venus has, as determined by satellite probes, a surface temperature of 800 degrees , much too hot to sustain life as we know it.
No human has ever landed on Venus. Spacecraft have been sent there, but due to the conditions they do not last very long.
For life to exist on Venus, the planet would need significant changes to its environment. This would include lowering its surface temperature, establishing a stable atmosphere with suitable conditions for life, such as oxygen and water, and shielding the surface from the planet's harsh radiation. It would be a massive undertaking to make Venus hospitable for life as we know it.
The "topography" of Venus is the three dimensional shape of the surface of Venus.
No life lives on Venus as we know. The conditions aren't right and it is way too hot.
Venera 13 was a Soviet spacecraft that successfully landed on Venus in 1982. It sent back data and images from the surface, providing valuable insights into the atmosphere and surface conditions of Venus.
The atmosphere on the surface of Venus is cloudy.
