This is a rather short-term endeavor, but we are also ignoring another key problem: a magnetosphere. Once we thin out Venus's atmosphere, we still need to address the lack of magnetosphere.

[@thebluelunarmonkey]

Exactly what I was thinking. If you remove venus' dense atmosphere, you also remove it's strong magnetic ionosphere, which protects its atmosphere from being blasted away by solar winds, since venus doesn't have a magnetosphere. Probably easier to create underwater spaces under Ganymede's ice crust deep enough to shield from Jupiter's radiation than to create a earth-like venus. Have little expectations from this video.

TERRAFORMING A SMALL PORTION OF MARS IN A DOME: Hi, I have been an environmental researcher since 1969. I discovered a method for growing grass on the surface of radioactive Uranium Mine tailings at Rio Algom Limited in Elliot Lake Ontario. ( confirmed). Grass can be grown on the surface of the planet Mars. I need Elon's help to conduct an experiment. Grass produces oxygen, for example, 50 sq feet of grass will produce enough oxygen for one person to breathe clean air. An airtight glass or plastic dome can be erected on the Mars surface, where grass will be planted where one person can dwell. Enough grass planted in this domed environment will create enough breathing oxygen to keep one person alive. A dome twice the size will allow two people to survive.

Venus is a good option. It would be best to tow it into Earth's orbit so it leads us, for easier commuting, and increases its spin so its days are the same length. It would also be visible in the sky if close enough as another earth. Eventually, you could build a whole chain of them. You would need to completely recondition the atmosphere and seed it with Earth's flora and fauna. It would take an entire army of robots, but I think the first step would be to move it and spin it up. The closer it is the easier it would be to exploit.

The thing most people don't get about Venus is that due to the different rotation direction a day cycle on Venus (sunrise, sunset, sunrise again, not a completed rotation around the axis, very important differencein that case), is about half a Venus year. If Venus rotated in the othere direction it would be almost tidally locked to the sun like the moon is to earth. Only gradually over the span of dozens of years managing to turn every part of its surface to the sun.

What is the purpose of trying to create an atmosphere suitable for humans, when it's just going to be stripped away. Instead we should concentrate on preserving the only planet we have capable of sustaining human life.
