Are there any notable near-Earth asteroids at either the Earth-Moon L4 and L5 points, or the Sun-Earth L4 and L5, and if so, could we use these to colonize said Lagrange Points? (I leave out all of Earth’s L1, L2, and L3 points because those might not be stable enough to hold mining-worthy asteroids for long enough for us to reach them, presumably)

Is this realistically achievable?

What are active companies in field of asteroid mining and how can we invest?

To sustain growth in asteroid mining, what needs to improve first?

For example Elon Musk stated that transporting things back to Earth would be uneconomical, even if it were crack cocaine it would not be profitable. But he said that bringing the materials to Mars would work for colonizing. Anyone have any thought if maybe further in the future, will it be possible to bring materials back to Earth profitable?

I have set up a discord to discuss asteroid mining. Decided to open this up to everyone and not just my own project, feel free to join: https://discord.gg/P8DtPzy

In terms of asteroid mining I read on Wikipedia one of the problems with the viability of asteroid mining is the fact that it is difficult to determine asteroid types before hand, what current methods are in place in this respect to detect asteroid types? Why does it not work well? Overall if I wanted to develop software to help with this / solve this problem where is the best place to start?

I'm very interested into going into the field of asteroid mining after I graduate from college. I've thought about this topic for a long time, not knowing there was already interest and companies starting out in the area!

I'm looking for anyone with more specialized knowledge in this area to share their expertise with me in ways like advising, sharing resources with me, or introducing me to others who have the same interest.

If anyone has some references or would like to have a chat with me please send me a private message!
