atmosphere - Venus vs Mars for colonization - Space Exploration …
Venus has nearly as deep a gravity well as Earth, and a much denser atmosphere. Launching spacecraft from Venus requires a multi-staged launch vehicle just like you'd need on Earth, except it needs to launch from a balloon floating in the atmosphere. A fully reusable Venus transport is basically impossible with any available technology.
Phosphine, yes -- but where are the organic compounds on Venus?
Sep 15, 2020 · 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.
Why is the atmospheric pressure on Venus so high?
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) e...
Will thinning the atmosphere of Venus make its surface habitable?
Nov 4, 2017 · 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.
What useful materials can be extracted from Venusian atmosphere?
May 20, 2015 · 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 ...
venus - What material properties would be necessary to shield a …
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 ...
Can Venus be made habitable? - Space Exploration Stack Exchange
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 ...
planetary science - How much sulphuric acid is on Venus? - Space ...
Feb 3, 2015 · This answer assumes that the 20 ppm value in the wikipedia article is correct and that it applies throughout Venus's atmosphere. The question also assumes that the 20 ppm is by mass rather than by volume. If the 20 ppm is by volume (which is typical), this alone more than halves the mass of the water in Venus's atmosphere. $\endgroup$ –
atmosphere - What is the atmospheric composition of Venus at …
Jan 13, 2020 · At cloud altitudes there's a lot we don't know about the composition of Venus's atmosphere. For instance, at or near the cloud-tops there's something that absorbs UV but its composition is still unknown — though there have been some suggestions, including biology (!), none are universally accepted.

Dec 24, 2016 · With that said, human color perception is complicated and depends on both the eyes and the brain, the sunlight above the clouds on Venus would be about twice as bright as on Earth, I don't know if that would have an effect on how our …
