Make the case, should we allow spaceflight into this site? Include manned and unmanned into the discussion.
In general I would think that Spacefligt should be included here since it's a focal point for future Astronomical advancement. Many visitors would floc-in just by that topic and then get involved in more Astronomy. This would in general rise the awareness of the general public on topics of Astronomy and Space Science.
Spaceflight does not come under Astronomy - but I do find it an extremely exciting topic and I'm sure there would be plenty of questions related to it. With that said, I would welcome spaceflight questions.
It perhaps is worth pondering, if they are not allowed here, where would one ask spaceflight oriented questions?
