A few of the space communities have been consolidated into !space@mander.xyz

Please see this link to the discussion: https://lemmy.ca/post/42167953

!space@mander.xyz is intended to be the most general community. You can also check out more specific communities such as:

• !astronomy@mander.xyz
• !spaceflight@sh.itjust.works
• others from the sidebar
