Roscosmos

Chief designer of the Soviet space program that Roscosmos institutionally succeeded; Korolev died in 1966, decades before Roscosmos was established in its modern form in 1992.

Glushko directed the Soviet space program until his death in 1989; Roscosmos was not established until 1992. The edge names the modern successor agency rather than a defunct Soviet body with no live entity here.

Flew under the Soviet space program that Roscosmos institutionally succeeded.

Flew under the Soviet space program that Roscosmos institutionally succeeded; Gagarin's 1961 flight predates the 1992 establishment of Roscosmos in its modern form.

Mir spans the 1991 handover: operated first under the Soviet space program from its 1986 launch, then by Russia's Roscosmos (renamed from the Russian Federal Space Agency in 2015) after the Soviet Union's December 1991 dissolution, through deorbit in 2001. This edge is kept and names the post-1991 operator; a new operated-by edge to soviet-space-program names the pre-1991 one (lane w-repair-space-soviet-0830, board 3427 gap).

Soyuz spans the 1991 handover: the spacecraft family was designed for and first flown under the Soviet space program from 1967; following the Soviet Union's December 1991 dissolution, Roscosmos (renamed from the Russian Federal Space Agency in 2015) continued to develop and fly Soyuz, and still does. This edge is kept and names the current/post-1991 operator; a new operated-by edge to soviet-space-program names the original one (lane w-repair-space-soviet-0830, board 3427 gap).
