Episode notes

Mercury orbits with a pretty fast gravitational, a pretty fast orbital speed around the sun because it's closer to the sun. But we could put something in Mercury's orbit that would have a slower speed and so it would co-track with the earth. And so this could be useful if you wanted to have a, either a chain of colonies or something like that. You'd probably use something like this to maintain that easy transferability. Or you could even use it as a space where the monitoring system, which we actually proposed in the paper. We can use the space infrastructure if you like the astrophysical infrastructure that's already there to our benefit.
