The Igla (Russian: Игла, "Needle") docking system was a Soviet radio telemetry system for automated docking of Soyuz spacecraft.[1] The first prototypes were made in late 1965. On 30 October 1967, the first automated docking of Soyuz unmanned spacecraft took place.[2][3]

Problems[edit]

  • The Soyuz 15 mission was aborted when the system failed to dock to the Salyut 3, on 26 August 1974. There was no manual backup system.[4]
  • Salyut 5, launched on June 22, 1976, was equipped with an improved radio system. On July 6, 1976, Soyuz 21 had problems docking automatically, but was able to manually dock. Soyuz 23 failed to dock, ran out of fuel to manual dock, and returned to Earth.[5]

Kurs[edit]

In 1986 Igla was succeeded by the Kurs docking system, first used on Soyuz TM-2.[6][7]
