DS ('Dnepropetrovsk Sputnik') were small satellites built by Yangel's OKB-586 / KB Yuzhnoye in the Ukraine for launch by the same KB's Kosmos launch vehicles. They were used for a wide range of military and scientific research and component proving tests.

Associated Launch Sites
  • Kapustin Yar Russia's first missile test range and used for satellite launches of smaller Kosmos vehicles. V-2's launched from here in 1946 were the first ballistic missiles fired on Soviet territory. It was greatly expanded as the test site for innumerable Soviet intermediate and short range missile projects in the 1950's.. Kapustin Year was also headquarters of the first operational R-1/R-2 units, 1950-1953, and later a base for 12 operational R-14 missile launchers. Kapustin Yar was known to have been used for over 3519 major launches from 1946 to 2007. More...
  • Plesetsk Plesetsk was the Soviet Union's northern cosmodrome, used for polar orbit launches of mainly military satellites, and was at one time the busiest launch centre in the world. The collapse of the Soviet Union put the main launch site of Baikonur in Kazakh territory. It now seems that once the Proton rocket is retired, Baikonur will be abandoned and Plesetsk will be Russia's primary launch centre. Upgrades to existing launch facilities will allow advanced versions of the Soyuz rocket and the new Angara launch vehicle to be launched from Plesetsk. Plesetsk's major drawback was the lower net payload in geosynchronous orbit from a northern latitude launch site. However Russia is planning to remove the disadvantage by looping geosynchronous satellites around the moon, using lunar gravity to make the necessary orbital plane change. More...

Second attempted launch of Cosmos 63S1 small launch vehicle 2LK with a DS-1 satgellite. This time the new second stage failed. The oxidiser was exhausted before orbital velocity could be reached due to uncontrolled pumping of liquid oxygen into the combustion chamber. The upper stage and satellite impacted in the Kurile Islands. An Expert Commission headed by Ustinov was convened to review the program.

After five months of further work and tests to improve the reliability of the second stage, Yangel's team felt it was ready to again attempt a launch of the 63S1 booster. 63S1 s/n 6LK put a DS-2 satellite into orbit, which conducted studies of the ionosphere. This was the first successful launch of the Kosmos 63S1 launch vehicle. A decision was made after two unsuccessful launches of the DS-1 to create a simplified DS-2 spacecraft based on the equipment and structural elements of DS-1 spacecraft. The cylindrical section for mission avionics was completely omitted.

  • Soviet Space Plans for 1963-1964 - . Nation: USSR. Related Persons: Smirnov; Korolev; Ustinov. Program: Soyuz; Vostok; DS. Flight: Vostok 7; Vostok 8; Vostok 9. Spacecraft: Zenit-2; Zenit-4; Soyuz A; Soyuz B; Soyuz V; Vostok. Meeting of the Interdepartmental Soviet of the Academy of Sciences reviews space exploration plans. In the next two years, 5-6 Luna probes will be sent to the moon, including soft landers with a mass of 100 kg, and orbiters to map the surface. There will be flybys and landings of Mars and Venus. Two Zond spacecraft will study the space environment out to 20 million kilometres from the earth. In earth orbit, 10 Zenit spy satellites, 10 to 12 Vostok manned spacecraft, 4 to 6 Soyuz spacecraft, and 10 to 12 Kosmos satellites will be launched. The Kosmos will fly missions in meteorology, communications, television transmission, and heliographic, and geological studies. Kamanin finds this a good program, but it nearly all relies on a single launch pad and one-time transmission of data from a few satellites. The military plan is not reviewed; it must go through the VPK Military-Industrial Commission first. An Expert Commission is to be formed on the Soyuz spacecraft. Smirnov and Korolev have dictated a letter to Ustinov asking that eight more Vostoks be built. On the other hand, some on the general staff want 60 cosmonauts trained in the next two to three years, to support 8 to 10 flights of single-place spacecraft and 7 to 8 flights of multiplace spacecraft.
