The troposphere on Venus contains 99% of the atmosphere by mass. 90% of the atmosphere of Venus is within 28 km (17.5 mi) of the surface; by comparison, 90% of the atmosphere of Earth is within 16 km (10 mi) of the surface. At a height of 50 km (31 mi) the atmospheric pressure is approximately equal to that at the surface of Earth. [34]
The highest point on Venus, Maxwell Montes, is therefore the coolest point on Venus, with a temperature of about 655 K (380 °C; 715 °F) and an atmospheric pressure of about 4.5 MPa (45 bar). [ 131 ] [ 132 ] In 1995, the Magellan spacecraft imaged a highly reflective substance at the tops of the highest mountain peaks, a " Venus snow " that ...
The main problem with Venus today, from a terraformation standpoint, is the very thick carbon dioxide atmosphere. The ground level pressure of Venus is 9.2 MPa (91 atm; 1,330 psi).
"Venus now has surface conditions that are extreme compared to Earth, with an atmospheric pressure 90 times greater, surface temperatures soaring to around 465°C (869°F), and a toxic atmosphere ...
With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 92 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.
Atmosphere of Venus in UV, by Pioneer Venus Orbiter in 1979. ... The air pressure at Venus' surface is about 92 times that of the Earth.
The ambient atmospheric pressure at sea level is not constant: it varies with the weather, but averages around 100 kPa. ... Surface of Venus: 92 atm [9] 1 km depth in ...
With its tenuous atmosphere, solar heat on the Martian surface readily escapes into space. The proposal would aim to allow liquid water to exist on the surface of Mars, which has water in the form ...
