That's rather odd, that Earth has been losing it's one and only
magnetosphere at the ongoing demise of -.05%/year, and yet that's not of any
interest to anyone within this group.

I guess Earth simply doesn't actually need nearly as much atmosphere, since
that'll have to be the next item that'll get solar wind extracted. Of
course, then we'll not have to bother going to Mars because, Earth's frail
environment will soon enough become rather Mars like.
