Soyuz 2 (Russian: Союз 2, Union 2) was an uncrewed spacecraft in the Soyuz family intended to be the target of a docking maneuver by the crewed Soyuz 3 spacecraft. It was intended to be the first docking of a crewed spacecraft in the Soviet space program. Although the two craft approached closely, the docking did not take place and the first successful Soviet docking of crewed spacecraft took place in the joint Soyuz 4 and Soyuz 5 mission. It served for the radio search and as a target vehicle for docking by the crewed Soyuz 3. Soyuz 2 soft-landed in a predetermined area of the Soviet Union.[1]

Soyuz programme |
Conceptual artist Joan Fontcuberta claimed in 1997 that Soyuz 2 was crewed by Ivan Istochnikov and a dog named Kloka, who disappeared on 26 October 1968, with signs of having been hit by a meteorite. According to Fontcuberta, Soviet officials deleted Istochnikov from official Soviet history to avoid embarrassment; however, the "Sputnik Foundation" discovered Istochnikov's "voice transcriptions, videos, original annotations, some of his personal effects, and photographs taken throughout his lifetime". The exhibition of artifacts (e.g., photographs) related to "Soyuz 2" was shown in many countries, including Spain, France, Portugal, Italy, Mexico, Japan, and the United States.[4][5] Among other reactions to the exhibition, a Russian ambassador "got extremely angry because [Fontcuberta] was insulting the glorious Russian past and threatened to present a diplomatic complaint".
Several lines of evidence available since the first exhibition of "Sputnik" in 1997 in Madrid suggested that the story and artifacts form an elaborate hoax:
