A Newly Discovered Document Debunks Soviet Space Conspiracy Theories on Soyuz-1.In April 1967, the Soviets launched veteran cosmonaut Vladimir Komarov on the very first mission of the Soyuz spacecraft. A day later, the cosmonaut died after his space capsule plummeted to Earth and crashed in Soviet Central Asia.As soon as Komarov's death was announced, conjecture and rumors quickly filled the vacuum created by the lack of hard information. Stories ranged from tearful goodbyes with family or officials to cursing the engineers and designers-but none of this, of course, was ever confirmed.In 2018, an official copy of the Soyuz-1 Onboard Journal was discovered at auction. While translating the document, author Asif Siddiqi recognized that it contained information not previously available, including details from the final hours of the Soyuz-1 flight.
