The course and manoeuvres taken by the aircraft in its last minutes has been determined from radar data and the on-board recorder.

Studied charged particle flows.

Maximum Speed - 5704 kph. Maximum Altitude - 63090 m.

The commission considers plans for the rest of the Soyuz production. Spacecraft s/n 14, 15, and 16 are to fly in August 1969, 17 and 18 in November 1969, and 19 and 20 in February-March 1970. Crews selected for the August flights are: for spacecraft 14, Shonin and Kubasov; for 15, Filipchenko, Volkov, and Gorbatko; for 16, Nikolayev and Sevastyanov. Back-ups will be Kuklin, Grechko, and Kolodin. All of the spacecraft will fly 4 to 5 day missions. Spacecraft 15 and 16 will dock and remain together 2 or 3 days to form an 'orbital station'. Experiments planned for the flight are:

• Visual observation of rocket launch plumes using the Svinets device
• Film and photography of the spacecraft 15-16 docking from spacecraft 14
• Demonstration of welding in weightless vacuum conditions using the Vulkan device
• Demonstration of autonomous navigation by the cosmonauts using a sextant
• Medium wave radio communications
• Test of new television sensors for the Soyuz orientation system

Spacecraft 17 through 20 will fly 15 to 16 day missions to demonstrate the new SZhO life support system for the L3, and conduct rendezvous and docking operations using the L3's Kontakt system. - Additional details.

Acting NASA Administrator George M. Low discontinued the quarantine for future Apollo flights to the moon beginning with the Apollo 15 mission. The decision was based on a recommendation of the Interagency Committee on Back Contamination (ICBC). The ICBC would continue as an active body, however, at least until the results of the last Apollo lunar mission were reviewed. Biomedical characterization of returned lunar samples would also be continued.

Continued operation of the long-range telephone and telegraph radio-communication system within the Soviet Union and transmission of USSR central television programmes to stations in the Orbita and participating international networks (international cooperation scheme).

Sixth Yantar second generation reconnaissance test flight and first completely successful flight. Both small SpK film capsules successfully recovered during course of flight, as was the main OSA cabin with its camera, computer, and main film cannisters. First full duration Yantar flight.

Heat Capacity Mapping Mission; prodeuced thermal maps of atmosphere. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

Global Positioning System.

High resolution photo reconnaissance; returned film in two small SpK capsules during the mission and with the main capsule at completion of the mission.

Began repair of Salyut 7 propulsion system fuel lines.

Magnetosphere and solar wind investigations. Prognoz-10-Intercosmos. Investigation of the structure of interplanetary and circumterrestrial shock waves generated by the interaction of the solar wind and the earth's magnetosphere. Carries scientific apparatus developed by scientists and specialists o f the USSR and the Czechoslovak Socialist Republic in the 'Intercosmos' programme of international cooperation in the exploration and peaceful uses of outer space.

Time 14 minutes.

Dual launch of operational Transits manufactured in the 1960's to replenish the constellation.

Given on Western lists as a geosynchronous ballistic missile early warning satellite. However not listed as such in Russian lists, and officially ...'conducted atmospheric, ocean studies. Investigation of the seas and oceans and the processes occurring in the earth's atmosphere'. So may have carried test instruments for second generation SPRN or had other purposes. Stationed initially at 12 deg E; Positioned in geosynchronous orbit at 24 deg W in 1988 As of 1 September 2001 located at 49.66 deg W drifting at 1.409 deg E per day. As of 2007 Mar 9 located at 70.52W drifting at 1.424E degrees per day.
