1"Mariner Mark II" was a spacecraft bus, from which CRAF2 [canceled] and Cassini-Huygens were derived, but some of the spacecraft features are different from Cassini as launched. The Mariner Mark II program from the 1990s and 2000s is not directly related to the Mariner program from the 1960s and 1970s. See https://ntrs.nasa.gov/citations/19880047876
2CRAF: Comet Rendezvous and Asteroid Flyby spacecraft, a NASA mission that was canceled. See https://ntrs.nasa.gov/citations/19930010071.
3"Mariner 77" may be an early reference to "Mariner Mark II"1.
