In the 1980s, American journalist James Oberg researched space-related disasters in the Soviet Union, but found no evidence of these Lost Cosmonauts.
Even with the availability of published Soviet archival material and memoirs of Russian space pioneers, no evidence has emerged to support the Lost Cosmonaut theories.
[2] In December 1959, the Italian news agency Continentale repeated the claims that a series of cosmonaut deaths on suborbital flights had been revealed by a high-ranking Czechoslovakian communist.
[2] A 1959 edition of Ogoniok published an article and photos of three high-altitude parachutists: Colonel Pyotr Dolgov, Ivan Kachur, and Alexey Grachov.
Heinlein speculated that Korabl-Sputnik 1 was an orbital launch, later said to be uncrewed, and that the retro-rockets had fired in the wrong attitude, making recovery efforts unsuccessful.
[6] In a U.S. press conference on February 23, 1962, Colonel Barney Oldfield revealed that an uncrewed space capsule had indeed been orbiting the Earth since 1960, as it had become jammed into its booster rocket.
[15] A similar story was told by French broadcaster Eduard Bobrovsky, but his version had the launch occurring in March, resulting in Ilyushin slipping into a coma.
After a guidance malfunction, the cosmonaut is reported to have made an unguided crash landing in China, too critically injured to announce the mission a complete success.
Despite the unsuccessful first test launch of the new Soviet N1 rocket on 21 February 1969, it is alleged that a decision was made to send a crewed Soyuz 7K-L3 craft to the Moon using an N1.
[19] In 1959, pioneering space theoretician Hermann Oberth claimed that a pilot had been killed on a sub-orbital ballistic flight from Kapustin Yar in early 1958.
However, Mike Arena, an American journalist, allegedly found in 1993 that an 'Ivan Istochnikov' and his dog 'Kloka', who were manning Soyuz 2, disappeared on October 26, 1968, with signs of having been hit by a meteorite.
[20] The entire story was found to be a hoax perpetrated by Joan Fontcuberta[21] as a 'modern art exercise' that included falsified mission artifacts, various digitally manipulated images, and immensely detailed feature-length biographies that turned out to be riddled with hundreds of historical as well as technical errors.
[22] 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: Andrei Mikoyan was reportedly killed together with a second crew member in an attempt to reach the Moon ahead of the Americans in early 1969.
In it, a Space Shuttle crew on a mission to repair a communications satellite encounters a derelict Soviet spacecraft with a dead crew—the result of a secret attempt to beat the United States to the Moon in the 1960s.
