The pressure on Venus is 1334 PSI (9.1976 MPa) or 92 times the pressure at sea level on Earth, which is 14.5 PSI (99.9734 kPa). Now, in our oceans the pressure increases by 14.5 PSI (99.9734 kPa) every 33 feet (10.058 m), or 9997.734 kPa every meter. So, we're told that the atmospheric pressure on Venus is equal to the pressure on Earth at 3036 ...
Venus however has the atmosphere can can support the changes for the end of time, however it requires much more complicated work to terraform the atmosphere than Mars would. Venus would be able to support a second earth and Mars can’t granted that the knowledge, technology and will to do so comes. Share.
For further reference, I suggest searching NASA Technical Report Server (NTRS) for Geoffrey A. Landis' works, perhaps staring with Colonization of Venus (PDF) that was published for 2003 Conference on Human Space Exploration proceedings, and concisely presents possibility of constructing aerostat colonies in Venusian atmosphere and natural ...
Currently on the surface the temperature is 467 °C, the air pressure 90 atmosphere, and there is no direct sunlight. 4 billion years ago Venus was like the Earth with liquid water on the surface. A runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of the levels of other greenhouse gases.
The presence of organic compounds in the Venus atmosphere is therefore a strong possibility. Reference. Otroshchenko V.A., Surkov Y.A. (1974) The Possibility of Organic Molecule Formation in the Venus Atmosphere. In: Oró J., Miller S.L., Ponnamperuma C., Young R.S. (eds) Cosmochemical Evolution and the Origins of Life.
Here is the actual composition of the Venus atmosphere. The nitrogen might not actually need to be removed. Here is my calculation of the N $_2$ mass: $$ m_{N_{2}} = (4.8 \times 10^{20} \text{kg}) \times 0.035 = 1.68 × 10^{19} kg $$ In comparison, the mass of Earth's atmosphere is $ 5 \times 10^{18} kg$ with about two-thirds nitrogen. It's ...
We have plenty of metallic materials that could stand the heat of Venus's atmosphere, including copper, nickel, cobalt, iron, titanium, tungsten, and chromium, to name but a few (here's a list of elemental melting points), as well as a large number of alloys including carbon steel and stainless steel. Even the sulfuric acid isn't a huge problem ...
Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. Above the dense CO2 layer are thick clouds, consisting mainly of sulfuric acid, which is formed by sulfur dioxide and water through a chemical reaction resulting in sulfuric acid hydrate.
Preliminary results (abstract only, the full paper is behind a paywall; full reference is: Atmosphere of Venus as Studied with the Mariner 5 Dual Radio‐Frequency Occultation Experiment, G. Fjeldbo, V.R. Eshleman, Radio Science Vol. 4 #10 pp 879-897, October 1969 DOI: 10.1029/RS004i010p00879) concentrated on the ionospheric results, but did ...
11. According to Wikipedia there are just 150 ppm of sulphur dioxide and 20 ppm of water in Venus' atmosphere. At the same time it is known that there is a considerable amount of sulphuric acid in the clouds. Venus' clouds are made of concentrated sulphuric acid, if I understand it correctly. This would suggest that the amount of sulphuric acid ...
