Planned but cancelled third mission to the Salyut 3 space station. References: 94 .
Final use of an Atlas booster in the Advanced Ballistic Reentry System (ABRES) program. References: 88 .
X-ray observatory. Cosmic X-ray astronomy. Injection point: 2.7S, 58.2E. Anticipated life: 5 years. Time of launch: 07:47:00.25 GMT. Decay also (belatedly) noted in ST/SG/SER.E/216. References: 1 , 2 , 5 , 6 .
Decay date suspect Uncertain if Molniya-1T model was Molniya-1 or Molniya-1T. Operation of a system of long range telephone-telegraph radiocommunication, and transmission of USSR Central Television programmes to the stations of the Orbita network. References: 1 , 2 , 5 , 6 .
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 .
Area survey photo reconnaissance satellite; returned film capsule. Second successful test of SpK small film return capsule planned for Yantar. SpK capsule FEU-170 No. 4L successfully recovered. References: 1 , 2 , 6 , 69 .
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 .
Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C). Launch vehicle put payload into geosynchronous transfer orbit References: 1 , 2 , 5 , 6 , 278 .
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.
ASTP Manned Test Flight. Check-out of the Soyuz space craft's on-board systems which had been modernized to meet the requirements of the 1975 joint flight in accordance with the programme of the Soviet-United States experiment; conduct of scientific and technical investigations. Landed 30 km NE Arkalyk. Recovered December 8, 1974 8:04 GMT. Additional Details: Soyuz 16. References: 1 , 2 , 6 , 32 , 33 , 60 .
Solar probe. Solar Orbit (Heliocentric). Launched by the United States and the Federal Republic of Germany. Helios A (Helios I). Heliocentric orbit 190 days, 0.309 x 0.985 AU x 0 deg. Exploration of the interplanetary space between the earth and the sun and study of solar influences on that area. References: 1 , 2 , 5 , 6 .
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 .
Experimental commsat. Jointly registered by the Federal Republic of Germany (A/AC.105/INF.305) and France (A/AC.105/INF.306). Symphonie flying model no. 1, constructed jointly by France and the Federal Republic of Germany. Description: Experimental teleco mmunications satellite. Orbit: geostationary. References: 1 , 2 , 5 , 6 .
