The four-stage Proton with the Blok D upper stage, built for the Soviet crewed lunar flyby program. It sends uncrewed Zond spacecraft around the Moon, Zond 5 carrying tortoises around it and back in 1968, as well as Luna sample-return and rover missions, the Mars 2 to 7 probes and Venera 9 and 10. Its early flights fail often.
