Summary

To travel to other planets, we will first have to build up are infrastructure closer to home, in orbit of Earth. The best place to get all the mass for those space stations and rocket fuel depots is from the Moon, and we'll examine the milestones we'll need to reach to start lunar resource harvesting and building up space settlements.

0:00.0	Hello, SFIA audio listeners. In this month's Nebula exclusive, Big Alien Theory,
0:05.2	we're asking the reason alien civilizations might be rare is because most aliens are huge.
0:10.5	To hear it and every episode early and add free, plus hours of bonus content,
0:15.1	check out go.nebula.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.0	This episode is brought to you by Brilliant.
0:23.0	They say a journey of a thousand miles starts with a single step, but a journey of a
0:28.0	billion miles, according to the National Space Society, will require 31 steps.
0:33.3	So today we are continuing our look at becoming an interplanetary species.
0:42.3	We're using the National Space Society's Roadmap to Space Settlement as a loose guide, and I've linked the complete document in the episode description.
0:45.3	In Part 1 we took a look at the first steps on the roadmap, developing some space-based
0:50.3	resources in commerce, lowering launch costs, and establishing a permanent foothold
0:54.6	in orbit.
0:55.6	Today we'll discuss part two of the roadmap, utilization and development of cis-lunar
1:00.3	space, though we'll not hold to it too rigidly.
1:03.9	Some of these milestones are projects we've looked at before, so I'll mention and link those
1:08.4	episodes as we go if you want to dive in a bit deeper.
1:12.4	Cis lunar space means between Earth and the Moon, but I frequently use it to refer to Earth's
1:17.0	entire hill sphere. This is the volume that Earth gravitationally dominates, which is about
1:22.0	3 million kilometers wide. It is the region in which objects could stably orbit Earth and
1:27.2	includes all Earth's
1:28.1	Lagrange points with the Moon and also Earth's L1 and L2 Lagrange points with the Sun,
1:33.2	and we'll discuss what those are very shortly.
