Venus, hottest planet after the sun in the solar system with a dense atmosphere. Its atmosphere is composed of carbon dioxide. The gravity is about 90% of earth’s gravity and it is 30% more close to the sun than the earth- these similarities makes it a desirable candidate for future colony building. But it also has some drawbacks like its atmosphere is 90 times thicker than ours, due to co2 ( carbon dioxide). It is too hot to melt heavy metals. It faces acidic rains of sulphuric acid which makes it a tough and harsh destination for future colony establishment.
Excess quantity of co2 results in the greenhouse effect, it traps a large amount of sun’s heat in the atmosphere which makes it hotter. The atmosphere temperature of venus is 450c (842F). Atmosphere pressure is very high due to its dense structure. Co2 itself crashes on the planet in the state in between liquid and gas and has properties of both states called “supercritical fluid”.
Russian scientists sent many probes on venus after every decade from the 1960s, most of them not even succeed to land on the surface. Only Venera 13 landed on the surface and worked for 2 hours before despair in high pressure and heat. It sent some pictures featuring a rocky, dry surface.
So here we have questions on surviving on the planet. A scientist Geoffrey Landis from NASA proposed the idea that the atmosphere on the planet is more likely to the earth’s atmosphere, 30 miles ( 50 kilometres) above the surface.
The atmosphere will provide us protection from the radiations and the temperature is quite comfortable for us (around 60c ), as we have technology to handle it. But the question remains here for the supplies of material or the life supporting elements for the colonies we will build there. We can use big balloons for this. As we need to know more about the atmosphere and the surface of Venus. We will develop some technologies to live and fight the harshness of the planet. We need big balloons of oxygen and nitrogen to survive there.
Venus is giving us hopes for the future. As our technologies are growing day by day, we will focus on other planets too, said by a scientist of NASA.
