Water and carbon dioxide from Venus? ( series)

A question arises as to what the feasibility is of these "high" orbits? It seems that for the Earth, that the moon would pose a problem. The gravitational pull of the moon may perturb a high orbit around the Earth, and thus sling it out of orbit. That would not be good. Consequently, a high Earth orbit may have to be restricted to a neighborhood closer to Earth than the moon, or in a LaGrangian point.

But Venus and Mars could be different. These two planets do not have such a large moon, as Earth does. Therefore, a high orbit around these planets may be workable. I did a Quora question about these types of orbits, and here are some good answers.

Why Venus and Mars? Each could be possible colonization sites. You could start with gathering carbon dioxide and water in order to make rocket fuel, as mentioned in this post.

This could be a new series of posts, beginning with this one. The first in the series is getting a bit busy, with too many updates. This one will begin with a discussion of mining Venus. Venus? The Delta-V for Venus is lower than for Mars, plus there ought to be more frequent launch windows. Getting there and back should be less of a problem than for Mars.

The problem will be in getting resources off of it. As everyone who follows this stuff knows, Venus has a horribly thick atmosphere, and a very high surface temperature. However, in the upper atmosphere, it is fairly mild in temperature and in pressure. Getting there may be a problem, though.

If you cannot get there easily enough, perhaps you wouldn't need to. What if you could do a LOXLEO approach? That is to say, you'd skim resources off the top of the Venusian atmosphere. You could get plenty of carbon dioxide, and perhaps plenty of sulfuric acid. The sulfuric acid will contain plenty of hydrogen, which could be mined for water.

Therefore, Venus could be a treasure trove of carbon dioxide and water. There is also some nitrogen in the atmosphere as well. What's not to like?

As usual, you'd have to get there with the necessary equipment. Even with a lower delta-v, getting to Venus with the necessary equipment could be an issue.

There would be an abundance of solar energy. Being that Venus is so much closer to the sun, the rays should be much stronger. The energy necessary for running the equipment could from there.
