Just for context, getting to the nearest solar system takes 4 years if you travel at the speed of light (186,000 m/s) and crossing the galaxy will take ~100,000 years. From then on, it’s millions of years to the next major galaxy.

Iirc we haven’t even reached 1% of light speed. So unless a revolution happens very soon, I don’t think intergalactic war is in the cards

We're not going to. Robots and remotes are getting better and better, there will be no need for us to go there at all before long - aside from the obvious need to get off the planet due to things like asteroid collisions, that is.

For exploration though, robots can (and will) do it better than we can.

Stable orbit is both a velocity and an altitude. Orbital velocity is dependent on orbital altitude. The absolute minimum before Earth's atmosphere interferes too much is 160 kilometers altitude at 17700 mph. Higher altitudes mean more velocity is needed to be in orbit.

We need a concrete set of international accords describing the process for claiming, capitalizing, and changing the orbits of interplanetary resources. Space capitalization would be an incredible step forward for human rights if done correctly because a lot of the conflict on earth is centered around control of strategic resources. The limitless supplies of the asteroid belt would alleviate that stress. On the flip side, miners could get treated like slaves if the companies feel as though they can do that. International law should also maybe be a little more concrete
