The space program under the erstwhile USSR was highly decentralized. The Russian Federal Space Agency aka Roscosmos was constituted by presidential decree after the Russian Federation emerged from the USSR.
The thing is, here on SpaceEx.SE, the tag 'russia' was used originally. The tag 'roscosmos' is a new entity. I started to apply the latter tag; then realized the tag-alternation may affect search-engine visibility.
- Should questions relating to pre-1992/Roscosmos space missions be tagged 'russia', and post-1992/Roscosmos space missions be tagged 'roscosmos'?
- Should all questions pertaining to space missions with a Russian/USSR affiliation carry both 'roscosmos', and 'russia' tags, or v.v?
- In the event of the latter i.e. tag with both 'russia', and 'roscosmos', which takes precedence when the 5-tag limit is met?
- Should 'roscosmos' be deleted as redundant?
