Failed lunar soil return mission. After successfully entering earth orbit, flying to the moon, entering lunar orbit, and descending toward the surface, the spacecraft was damaged during landing in Mare Crisium (Sea of Crises). The sample collecting apparatus could not operate and no samples were returned. The lander continued transmissions for three days after landing. In 1976, Luna 24 landed several hundred meters away and successfully returned samples. Parameters are for lunar orbit. References: 1 , 2 , 5 , 6 , 67 , 274 , 296 .

AMSAT-OSCAR 7 was launched piggyback with ITOS-G (NOAA 4) and the Spanish INTASAT. The second phase 2 satellite (Phase II-B). Weight 28.6 kg. Octahedrally shaped 360 mm high and 424 mm in diameter. Circularly polarized canted turnstile VHF/UHF antenna system and HF dipole. Firsts: Satellite-to-satellite relay communication via AO-6; Early demonstrations of low-budget medical data relay and doppler location of ground transmitters for search-and-rescue operations were done using this satellite. AO-7 was operational for 6.5 years until a battery failure ceased operation in mid 1981. Additional Details: Oscar 7. References: 1 , 2 , 5 , 6 .

From 1972, as the last open-pad missiles were retired, it was decided to mount all warheads on the silo-based missiles in instant readiness for launch. Its operational tasks finished, the 12th Directorate was placed under the Ministry of Defence. In its place the RSVN created a Sixth Directorate for security of nuclear weapons.

Yantar second generation reconnaissance spacecraft. After failure of the first Yantar-2K launch, a review board recommended modifications to the Soyuz U launch vehicle. This second Yantar still used the Sokol control system from the Zenit and lacked the SpK small film recovery capsules. As planned, after 12 days, the main descent capsule was successfully recovered with its film. References: 1 , 2 , 6 .
