Floating cities of venus
Venus is the neighbor of earth. The colonization of venus seems science fiction but it is possible to now about floating cities of venus stay connected.
We are developing our technologies for space colonization and we are finding new places for humans because we knew that someday due to overpopulation, natural calamity, or any comic event can destroy the earth, therefore we are finding a new alternative (planet) which can sustain human life. Colonization of space has been claimed by Stephen Hawking to be the best way to ensure the survival of human as a species.
Atmosphere of Mars:
- Venu’s atmosphere is made mostly out of carbon dioxide. Because nitrogen and oxygen are lighter than carbon-dioxide, breathable-air-filled balloons will float at a height of about 50 km (31 mi). At this height, the temperature is a manageable 75 °C (348 K; 167 °F); or 27 °C (300 K; 81 °F) if we could get 5 km (3.1 mi) higher (see Atmosphere of Venus Troposphere). The atmosphere also provides the various elements required for human life and agriculture: carbon, hydrogen, oxygen, nitrogen, and sulfur. Additionally, the upper atmosphere could provide protection from harmful solar radiation comparable to the protection provided by Earth’s Atmosphere . The Atmosphere of Mars , as well as the Moon provide little such protection. And also venus is the nearest planet to earth so it is easier to communicate and transportation.
Venus also presents several significant challenges to human colonization. Surface conditions on Venus are difficult to deal with: the temprature at the equator averages around 450 °C (723 K; 842 °F), higher than the melting point of lead, which is 327 °C. The atmospheric pressure on the surface is also at least ninety times greater than on Earth, which is equivalent to the pressure experienced under a kilometer of water, therefore humans cannot survive on the surface of venus
Floating Cities :
Because of habitat atmospheric condition of venus, it is possible to build floating structures which can sustain human life and it will have all the facilities we required in daily life and everything which scientists need to do research. We can build floating structures attached to balloon In 1971 Soviet scientists have suggested that rather than attempting to colonize Venus’ hostile surface, humans might attempt to colonize the Venerian atmosphere (atmosphere of venus). “However, viewed in a different way, the problem with Venus is merely that the ground level is too far below the one atmosphere level. At cloud-top level, Venus is the paradise planet.” Protection against cosmic radiation would be provided by the atmosphere above, with shielding mass equivalent to Earth’s. Over 20 successful space missions have visited Venus since 1962. Other low-cost missions have been proposed to further explore the planet’s atmosphere, as the area 50 km (31 mi) above the surface where gas pressure is at the same level as Earth has not yet been thoroughly explored.
The wind speed on Venus reaches up to 95 m/s (340 km/h; 210 mph), circling the planet approximately every four Earth days, in a phenomenon known as “super-rotation”.Compared to the Venusian solar day of 118 Earth days, colonies freely floating in this region could therefore have a much shorter day-night cycle. Allowing a colony to move freely would also reduce structural stress from the wind than they would if tethered to the ground.
There is no significant pressure difference between inside and the outside of the balloon, any rips or tears would cause gases to diffuse at normal atmospheric mixing rates rather than an explosive decompression, giving time to repair any such damages. Humans would not require pressurized suits.
Structural and industrial materials would be hard to retrieve from the surface and expensive to bring from Earth/asteroids. The sulfuric acid itself poses a further challenge in that the colony would need to be constructed of or coated in materials resistant to corrosion by the acid, such as PTFE (a compound consisting wholly of carbon and fluorine).
NASA developed the (High Altitude Venus Operational Concept) HAVOC, exploring the possibility of setting up an atmospheric manned mission, in 2015.
