RLF  Project
Russian Longterm Flight

Project description

"RLF" () was a joint endeavour of Austrian and Russian experts in the area of spaceflight medicine and physiology. RLF was organized by the Institute of Biomedical Problems (IBMP) Moscow, and–under the auspices of the Austrian Ministry for Sciences and Research–by the Austrian Society for Aerospace Medicine in Vienna. RLF built upon the successful AUSTROMIR mission in 1991, which sent an Austrian cosmonaut for 1 week aboard the MIR space station.

RLF investigated, from 1993 to 1997, cosmonaut's body functions before, during, and after sojourn in orbit of several months duration each - the longest being the legendary world record of 14 months:

Cosmonaut Dr. Valeri Vladimirovich Polyakov - born April 27, 1942, in Tula, Russia. Pilot-cosmonaut, Hero of the Soviet Union. Now Deputy Director, IMBP. Academician, Vice-President of the Tsiolkovsky Cosmonautics Academy, Russia. Total time spent in space: 678.7 days. Longest space flight in history - flight time: 437.75 days. The 15th Main Expedition Crew, comprising V.M. Afanasev, Y.V. Usachev, and V.V. Polyakov, was launched with Soyuz TM-18 on January 8, 1994. The capsule docked at MIR's Kvant module on January 10. The Austro-Russian biomedical experiments formed an integral part of this mission:
