I have an idea of how to terraform Venus for about 20 years. This is a rough description of the idea without technical details.

I have an idea of hiding the whole planet Venus from the sunlight behind a shield of thin aluminum. It should be a round object made of thin aluminum foil in orbit around the Sun between the Sun and Venus, with the size of the planet or drone ships would be delivered to Venus’s orbit. The orbit of the drone ships should be calculated so that the drone ships always stay between the Sun and Venus, forming a shield that shields Venus from the sunlight.

Here are some calculations from me: 1 square meter of aluminum foil, 6 microns thick, should weigh about 16 grams. That means for 1 square kilometer (1,000,000 square meters), it should be 16,000 kg. If the squared area of a circle completely covering Venus is about 115,000,000 square kilometers, that will be about 1,840,000,000 tons of aluminum foil.

That means it will be impossible to lift this amount from Earth to space. It has to be mined in space. I would suggest using some asteroid or asteroids. This means autonomous mining should be developed, where AI and robots will mine the aluminum from some asteroid or asteroids and manufacture drone ships with maybe a foil shield with the size of 1 square kilometer. These drone ships would then be delivered to Venus’s orbit. The orbit of the drone ships should be calculated so that the ships always stay between the Sun and Venus, forming a shield that shields Venus from the sunlight.

I suppose it will not be necessary to cover the entire planet Venus from the Sun; maybe it will be enough to cover half of the planet. Further calculations and mathematical and physical models are needed to measure the exact coverage that will decrease the temperature of Venus to about 20 degrees celsius on planet surface on equator.

Така че 1 квадратен метър от алуминиево фолио с дебелина 6 микрона би тежал приблизително 16.2 грама.
1 кв километър 16 кг
115 000 000 кв километра площ на квадратурата на кръг покриващ напълно венера.
1 840 000 000 тона фолио.

Трябва да бъде добит алуминия във космоса и доставен на орбита около Венера. Четете англииската версия за по нататъчни обяснения.
