In 1985 engineers involved in an industrial project to irrigate the Gobi Desert accidentally unearth a mysterious and apparently artificial spool. When found to be made of a material unknown on Earth, the spool is circumstantially linked to the Tunguska explosion of 1908. The spool is seized on as evidence that the explosion, originally blamed on a meteor, was actually caused by an alien spaceship. Professor Harringway deduces the craft must have come from Venus. The spool itself is determined to be a flight recorder and is partially decoded by an international team of scientists led by Professor Sikarna and Dr. Tchen Yu. When radio greetings sent to Venus go unanswered, Harringway announces that a journey to Venus is the only alternative. The recently completed Soviet spaceship Cosmostrator intended to voyage to Mars, is redirected to Venus, a 3031 day journey. During the voyage, Sikarna works furiously to translate the alien message using the spaceships computer.When their spaceship nears Venus, radio interference from the planet cuts the crew off from Earth. By then, Sikarnas efforts lead to a stunning discovery The spool describes a Venusian plan to irradiate the Earths surface, with the extermination of mankind being the prelude to an invasion. Rather than containing a cosmic document, as had been expected, the spool bears a coldblooded message of destruction. Harringway convinces the crew to press on towards Venus rather than return to Earth with news that would panic mankind. ........
