Or send some microbes which convert it into oxygen. You are right Mars doesn't have enough resources to support anything.

The problem is that Venus is missing important ingredients for life. Most notably is the lack of hydrogen.

If you are interested in learning more on hypothetical approached of terraforming Venus, I suggest reading this Wiki article: https://en.wikipedia.org/wiki/Terraforming_of_Venus#Biologic...

But the outer planets have excesses of hydrogen, so round trips could help there?

The upside is, of water aka H2O that we need, the 2 H atoms are the lighter component, specifically:

2H = 2 * 1.67 * 10(-24) grams 1O = 1 * 2.65 * 10(-23) grams

So hydrogen is 11% of water, and oxygen is 88%;

meaning every kg hydrogen can combine with 8kg oxygen to give 9L water.

So all the Oxygen already being there (in CO2) is good.

Also Venus is closer (minimum 38.2 million kilometer for Venus vs minimum distance of 55.7 million for Mars).

However I don't know about the microbes, i fear that they might get killed at an average temperature of 737 K (464 C).

You cant really use distances for orbiting bodies like that. But it is true it's easier to get there.

Hopefully someone can provide more info, but apparently there are some bacteria in geothermal vents near Baja California that seem to be able to handle venus-like conditions. No idea what the details are though

that's an interesting proposition. If terraforming is really about engineering the right microbes to slowly (over several millenia even?) the atmosphere to habitable for humans, do we currently have the technology to actually accomplish it? Or is it still too advanced form of engineering?

We can't even terraform the Earth.

I think biology-wise it’s a question of money. We might not be able to engineer such microbes just right now, but we could if we had more resources dedicated to it.

With concerted effort I’m sure we can do something about it in a couple decades at best.
