VENUS -projects and ideas for terraforming this world into a New Earth

The planet Venus has the same gravity as Earth, it is twice as close to the Sun as we are.

After the Venusian terraforming there would be two perfectly habitable areas from the start, namely the polar areas that are permanently lit by the sun, ie there we have an eternal day (if instead of ozone we had a gas from floating micro-bubbles with hydrogen that would generate a fluorescent refraction-reflection effect from the light side of the planet to the dark side of it considering that the Venusian day and night last for a whole year). about 243 Earth

On Venus, a day lasts about 243 Earth-days. That's longer than it takes the planet to complete an orbit around the Sun. So, a Venusian year actually spans just 225 Earth-days

Until we reach the level set out above, we will have to get rid of the dense Venusian atmosphere of carbon dioxide, which is currently at approx. 100 atmospheres pressure and approx. + 400-500 degrees Celsius.

The whole thing could be done by a single intelligent gas with floating micro-bubbles, gas shield that would become opaque to light and thus keep the planet Venus cold and very cold.

The cooling of the planet will also be done by a stationary shadow, a screen solar satellite located quite close to the Sun and perfectly synchronized with the Venusian position and motion in orbit, so the remaining carbon dioxide could solidify and deposit on the Venusian surface in large caps just like on Mars but not in the habitable polar zones but on the rest of the planet where it will be an eternal evening.

This solution could be applied singularly as a complete solution.

Carbon dioxide becomes and remains solid at -50 / -70 C and a pressure of over 5 atm, so the entire Venusian atmosphere could be reduced to carbon snow and would remain a nitrogen atmosphere.

We would quickly get a planet like Mars but with an atmospheric pressure similar to the terrestrial one and made up mainly of nitrogen and some oxygen, and the polar areas would be warm and habitable.

Water would be obtained by deep drilling.
