There is also a likeliness that Venus never saw liquid water on its surface. As Venus was always hotter than Earth, water might have stayed supercrtical and later removed by the Solar Wind. As Venus does not display any evidence of liquid water flows (unlike Mars), we will never know...

Earth absorbed the water as it formed a spiral ring that came within the Earth and Moon's orbit.

For cooling, you can put "sunshades" between the sun and Venus. You could make them almost tinfoil-thick and cover a massive area with relatively little effort. Plausibly doable now, if you could find the money. There's too much carbon dioxide in the atmosphere. Sequestering some in the basalt crust, or the silicon dioxide in the mantle, might be options. Bombardment won't eject much carbon dioxide. Nudging an object from the Kuiper belt into Venus' orbit, with enough mass to potentially give Venus a new moon, is an idea. Directly removing the carbon dioxide is surprisingly difficult, courtesy of the high escape velocity and dense atmosphere (~90bar). Bombarding it with hydrogen does get you two birds with one stone; turning carbon into graphite and oxygen into water. You'd only need something in the range of 40,000,000,000,000,000 tonnes. On the more theoretical side, you could build a large "stellaser", that would draw both power and hydrogen directly from the sun, to "shoot" hydrogen at Venus. If you do manage to thin Venus' atmosphere, congratulations! Courtesy of the planet's slow rotation speed, there's now a massive temperature difference between sun-side and dark-side. Might have to expand those solar shades to regulate an artificial day/night cycle. Also, you still don't have a proper magnetosphere. Serious terraforming of planets is an arduous, and typically destructive, process.

@dphuntsman

Need hydrogen. If we were seriously interested in terraforming Venus, “easiest” way might be steering comets into it which adds water/hydrogen (but also, energy).

@tsovloj6510

The Bosch reaction would be the easy one (hydrogen + CO2 in the presence of an iron catalyst produces graphite and water), and it produces energy, so it's got a great cost/benefit ratio if you're thinking terraforming thoughts, but you'd need to import the hydrogen, which would be a long and laborious process; you'd either have to truck it in from the outer system gas giants (probably Uranus, least steep gravity well) or somehow harness the solar wind. This is a centuries to millennia type of project, realistically.

First you need to have Space Tug boat ships. Then send those space tug boats to tow any huge ice rocks over the very "vast" distances required to find them by scanning the solar system... most of them may be found closer to the Asteroid Belt and beyond and the towing has to be very controlled... Next drop those large ice covered rocks or hopefully higher percentage ice balls on to Venus. Next you will need a significant amount of ice rocks to drop on Venus...

Can't understand what she's saying.

Good topic but bad narration. Slow down, pause a bit for strong effect.

It's taken decades of landing rovers on Mars to theorize the amount of water Mars once had. Venus has had a fraction of that exploration, so exactly how have we determined the amount of water that was once on Venus? Is it just an assumption that it must have had as.much water as Earth because of its size? Considering the prominent theories of how Earth got its water, how could you make that assumption?

If it evaporated then where did it go? Shouldn't there be traces of the gas in its orbit?

Yes. Even on Earth, where the gravity is significantly stronger than Mars and Venus, Hydrogen is still light enough to escape the atmosphere into space. The reason this isn't a big deal on earth is because almost all of our hydrogen is bonded to oxygen in water molecules, and because our atmosphere is protected from solar winds by our magnetic field. There is some water on mars, but it's all either underground, chemically bound in the rocks or frozen solid at the poles. The reason Mars has hardly any atmosphere anymore is because it's magnetic field disappeared a long time ago. The convection of molten iron in the core is what creates the magnetic fields of earth, but on Mars the core cooled down much faster than earth because it's 9 times less massive. Without a magnetic field, Mars' atmosphere was gradually blasted into space by high energy charged particles from solar storms.
