Where to go if you want to get into the space industry

Hi everyone,

I'm looking for advice and suggestions to help my husband. He is an incredibly talented CTO who recently sold a company that had gone through Techstars. His background is in fintech but he is deeply passionate and obsessive about the space industry. He's a startup guy through and through, so something early stage.

He's not sure where to start looking or how to begin getting involved. I'm hoping there are some other folks in this community who are passionate who could point me to any communities, newsletters, or places for him to start looking and researching. Any ideas/resources would be immensely appreciated.

Thank you!
