I mean more like space tech and launches, not astronomy (though I wouldn't mind a bit of that).

I wanna stay updated but know literally no good sites.

Ads are ok if not disruptive or inappropriate. RSS would be nice.

Youtube channels / newsletters or other forms of media work too as long as they're good (except for podcasts, don't listen to those).

You can point to a lemmy community, but I never rely exclusively on an aggregation site for news.
