Failed · FailureLuna 1969B
NSSDCA’s current planetary chronology independently lists Luna 1969B on 1969-04-15 as an attempted lunar sample-return mission with launch failure, corroborating the date and broad mission class in its tentative-launch page. The sources do not identify a serial number or failure phase. NASA’s Proton history does not corroborate this as a fifth January–April Proton failure, so vehicle identity and whether it reached Earth orbit remain unresolved.

Launched 1965
Failed · FailureVenera 1965A
NASA NSSDCA’s tentative-launch page lists a possible failed Venus flyby on 26 November 1965, while its Venus chronology lists Venera 1965A on 23 November, the date of Cosmos 96. NASA’s Deep Space Chronicle calls Cosmos 96 the third and last Soviet spacecraft prepared for a 1965 Venus encounter, but does not discuss the separately dated tentative entry. Whether that entry denotes a distinct launch remains unresolved; no outbound trajectory is assigned.

Failed · FailureVenera 1964A
The second 3MV Object-Probe technology attempt failed at third-stage ignition on February 19, 1964, after a leaking oxygen valve caused a frozen fuel pipeline to rupture. It did not attain Earth orbit. Both inspected accounts identify a flyby/technology bus without a carried lander.
