1. Story
2. The ambitious multi-spacecraft Grand Tour programme studied at the start of the 1970s, using a new self-repairing spacecraft design, was cancelled on cost grounds. What survived was a smaller, approved mission to Jupiter and Saturn only, using two spacecraft derived from the Mariner line; it was renamed Voyager shortly before launch. The capability to continue to Uranus and Neptune was not formally part of the approved mission, and Voyager 2's trajectory was designed to preserve the option without depending on it.

74. Evidence
75. The canonical mission record for both spacecraft: launch dates of 20 August 1977 (Voyager 2) and 5 September 1977 (Voyager 1), the Titan IIIE-Centaur launch vehicle, Launch Complex 41 at Cape Canaveral, the eleven-instrument science payload and the three-generator power system. V55 verification basis: THE CATALOGUE WAS NOT REACHED. nssdc.gsfc.nasa.gov returned EGRESS_BLOCKED when fetched and the search budget was exhausted before it could be searched; the COSPAR designations and every fact attributed here come from standard mission record held in general knowledge, not from the catalogue. This record names where a curator should check, not what was checked.
