I noticed that we have two tags that appear to be very closely related: (171 questions) and (23 questions). The question overlap between them is minimal; only four questions are tagged with both.

The tag wiki don't really provide any guidance on the difference between the two. crewed-spaceflight:

Crewed spaceflight (also referred to as human spaceflight or manned spaceflight) is space travel with a crew aboard the spacecraft. When a spacecraft is crewed, it can be operated directly, as opposed to being remotely operated or autonomous.

and crewed-missions:

Use this tag for questions relating to missions that are manned by a crew.

What's the difference between the two? Which should I use when? Or should they be merged?

  • $\begingroup$ Suggest it as a synonym, and I'll merge. I agree, they sound pretty much the same thing. $\endgroup$

  • $\begingroup$ @PearsonArtPhoto I don't have 5 score in either tag, so can't suggest a synonym. I do however suggest keeping crewed-spaceflight in that case because of its existing counterpart uncrewed-spaceflight, obsoleting crewed-missions. (I probably could go in and edit some of my older questions, but that seems like... cheating.) $\endgroup$

  • $\begingroup$ I suggested they be synonyms, I await the decision of SESX overlords. :-) $\endgroup$ Commented Jul 6, 2016 at 21:27
