Soyuz 7K-MF6 Chronology
  • 1976 September 15 - Soyuz 22 - Program: ASTP. Crew: Aksyonov, Bykovsky. Flight: Soyuz 22. Launch Site: Baikonur. Launch Vehicle: Soyuz. Mass: 6,510 kg (14,350 lb). Perigee: 185 km (114 mi). Apogee: 296 km (183 mi). Inclination: 64.80 deg. Period: 89.30 min. Duration: 7.91 days.

    Surplus Soyuz ASTP spacecraft modified with a multi-spectral camera manufactured by Carl Zeiss-Jena in place of the universal docking apparatus. Eight days were spent photographing the earth. Tested and perfected scientific-technical methods and devices for studying the geological characteristics of the earth's surface from outer space for economic purposes.
