Kosmos 305 ( Russian: Космос 305 meaning Cosmos 305) (Ye-8-5 series) was the fifth Soviet attempt at an uncrewed lunar sample return. It was probably similar in design to the Luna 16 spacecraft. It was launched, on a Proton rocket, on October 22, 1969. [3] The engines on the Block D upper stage failed, terminating the mission. This left the spacecraft stranded in Earth orbit. It re-entered within two days. [4]
