    Space-flown and used annotated Instruction Logbook for the KRT-10 Radio-Telescope Assembled Aboard the Salyut 6 Space Station in 1979

    Salyut 6 KRT-10 Radio-Telescope Annotated Instruction Logbook Flown and Used in Space. 100 pages, 7.5" x 10.5". The loose-leaf pages are held together with three metal rings. Sections of the logbook were printed between November 29, 1978 and June 28, 1979. This logbook, copiously illustrated with diagrams, provides detailed instructions for assembling and testing the KRT-10 radio telescope. There are numerous pencil notations by cosmonauts Vladimir Lyakhov and Valery Ryumin. After the flight, this logbook was presented to Dr. Boris Vasilievich Afonin, flight training instructor. A photocopy of a letter from Afonin is present.

    The Salyut 6 Space Station was launched into orbit by the Soviet Union on September 29, 1977. On February 25, 1979, Soyuz 32 was launched with cosmonauts Lyakhov and Ryumin aboard. They arrived at Salyut 6 the next day. On June 28, 1979, Progress 7 was launched by a Soyuz rocket with the KRT-10 radio telescope and, most assuredly, this instruction logbook, as part of its cargo. It docked with Salyut 6 two days later. Progress 7 undocked on July 18th and the 10 meter diameter parabolic dish aerial of the KRT-10 unfurled as it was released from the docking tunnel between Progress 7 and Salyut 6, where it was installed by the Salyut 6 crew using this instruction logbook. Work with the KRT-10 radio telescope was completed on August 9th and when cosmonauts Lyakhov and Ryumin attempted to jettison the aerial, it became entangled with some of Salyut 6's external projections. On August 15th, the cosmonauts "spacewalked" and freed the entangled KRT-10. During this time they no doubt made entries into this logbook. Lyakhov and Ryumin returned to Earth on August 19, 1979 aboard Soyuz 34.

    The 175 day mission of Soyuz 32/34 was marked by a pair of 15 kopeck Soviet postage stamps. The fully-unfurled rad
