Terraforming Venus
Posted: 02 Aug 2022, 06:45
Venus is in a scorching hell. It is covered with a dense atmospheric "bedding". Moreover, it is close to the sun. Venus is bathed in 1.9 times more energy than the Earth. In addition, it has no water and no plate tectonics. Furthermore, it is in a state of super-rotation (which does not need to be resolved). Furthermore, the rotation period is 243 days. And it is in retrograde.
The way to solve these problems is bold. First, the orbit of the asteroid outside the snow line must be precise, and in the shortest possible time. Then, the asteroid's rotation period would have to be adjusted to be precisely close to that of the earth, and its atmosphere would have to be blown away. Then we would try to hit it. That way, in addition to supplying a large amount of water, it would also blow up the atmosphere. But this would take a lot of labor, plus impossible orbital adjustments and other impossible things.
A further idea, therefore, is to build a giant sun shield at the L1 Lagrangian point on Venus. However, sunlight may cause orbital misalignment, but if a secondary mirror is placed to shine light on the sun shield, orbits will not be misaligned.
This would cool the temperature and make carbon dioxide fall as rain. If the temperature is lowered enough to turn the carbon dioxide into snow, the atmospheric pressure would drop rapidly. Venus would then have just the right pressure, but the temperature would be too low. In addition, there is still carbon dioxide on the ground. We can launch them by a mass driver to the Venusian sky.
But there is no water. Then there is Europa. Europa has a large amount of water, which can be used by combining a skyhook and a mass driver. Then we can send a large amount of water to Venus. The water would be sprayed on Venus. The water would then fall as snow. Then we would remove some of the solar shielding over the planet. This would warm up the planet, and Venus would become moderately warm.
Another problem is that Venus has a slow rotation period. This would make it hot on one side and very cold on the other. One side will be hot and the other side will be very cold. If this is the case, we can set up a mirror above Venus and adjust the sun's rays so that they circle the planet in 24 hours.
We can terraform Venus in this way. But these methods are not possible with the technology that mankind has "now". Maybe future technology will make this possible, but will the money to terraform Venus be worth the return on terraforming Venus? If we are going to spend money on such a thing, why not make the earth a better place, in my opinion?
