Soyuz 7

In this article, the fascinating topic of Soyuz 7 will be addressed, which has aroused great interest in today's society. Soyuz 7 has been the subject of numerous studies and debates, since its impact is relevant in different aspects of daily life. Over time, greater knowledge about Soyuz 7 has developed, which has allowed us to understand its importance and implications in various areas. In this sense, it is extremely relevant to fully explore this topic to understand its complexity and its possible effects on our society. Therefore, throughout this article different perspectives about Soyuz 7 will be analyzed and we will seek to offer a comprehensive vision that allows us to understand its true scope.

This article is about a 1969 spaceflight. For the proposed carrier rocket, see Soyuz-7 (rocket). For the mission identified by NASA as ISS Soyuz 7, see Soyuz TMA-3.

Soyuz 7 (Russian: Союз 7, Union 7) was part of an October, 1969, joint mission with Soyuz 6 and Soyuz 8 that saw three Soyuz spacecraft in orbit together at the same time, carrying a total of seven cosmonauts.

The crew consisted of commander Anatoly Filipchenko, flight engineer Vladislav Volkov and research-cosmonaut Viktor Gorbatko, whose mission was to dock with Soyuz 8 and transfer crew, as the Soyuz 4 and Soyuz 5 missions did. Soyuz 6 was to film the operation from nearby.

However, this objective was not achieved due to equipment failures. Soviet sources later claimed that no docking had been intended,[citation needed] but this seems unlikely, given the docking adapters carried by the spacecraft, and the fact that the Soyuz 8 crew were both veterans of the previous successful docking mission. This was the last time that the Soviet crewed Moon landing hardware was tested in orbit, and the failure seems[citation needed] to have been one of the final nails in the coffin of the programme.

The radio call sign of the spacecraft was Buran, meaning blizzard, which years later was re-used as the name of the entirely different spaceplane Buran. This word is apparently used as the name of an active or aggressive squadron in Soviet military training, and just like Soyuz 4, the Soyuz 7 spacecraft was constructed to be the active or male spacecraft in its docking.

Mission parameters

  • Mass: 6,570 kg (14,480 lb) [1]
  • Perigee: 210.0 km (130.5 mi) [5]
  • Apogee: 223.0 km (138.6 mi)
  • Inclination: 51.65°
  • Period: 88.77 minutes

Mission

The mission objectives included:[1]

  • checkout the modified structure of the Soyuz craft,
  • further improvement of the control, orientation, and orbital stabilisation systems and navigation aids,
  • debugging the piloting systems by orbital maneuvering of the spaceships in relation to one another,
  • testing of a system for control of the simultaneous flight of three spacecraft,
  • scientific observations and photographing of geological-geographical subjects and exploration of the Earth's atmosphere,
  • studying circumterrestrial space,
  • conducting experiments of engineering research and biomedical engineering importance.

Return

The ship was involved in group flight with Soyuz 6 and Soyuz 8. Docking did not occur, and the ship landed 5 days after launch, at 155 km at the northwest of Karaganda, Kazakhstan.
