Ask HN: How to get ideas for space startups?

My idea of space has been limited to telecommunication & space exploration.

I came across Varda Space Industries, which takes advantage of microgravity to manufacture drugs in ways that would otherwise be extremely difficult to make on earth.

One of the founders hinted that this idea was from reading NASA research on experiments done in space.

Any cool space startup ideas you have based that are not exploration (tourism) or communication?

Or resources that can help me come up with ideas?
