Russian earth land resources satellite. 11 launches, 1987.12.26 (Cosmos 1906) to 1995.09.26 (Resurs F2 N.10). Adaptation of recoverable Vostok spacecraft for remote sensing.

Investigation of the natural resources of the earth in the interests of various branches of the national economy of the USSR and international cooperation. Film resolution 9-12 m black and white, 15-18 m multispectral (4-6 spectral bands). Swath width 150 km; total area covered per mission 20.7 million square km. Missions: Cosmos 1906, Cosmos 1965, Cosmos 1990, Resurs-F7. Transmission frequencies observed in West: 231.5 PCM-FM.

In 1987 a more capable version of the Resurs-F1, the Resurs-F2, began operations. The most significant improvement was the addition of two small solar arrays attached to the base of the orbital propulsion unit which permitted active missions for up to a full month. The first mission in late 1987 by Kosmos 1906 was not entirely successful, and the spacecraft was intentionally destroyed in orbit. Four more missions were conducted during 1988-1990, followed by three flights in 1991- 1992.

The Resurs-F2 photographic system differed from that of its predecessor. The SA-M system with its MK-4 camera combined the high resolution of the SA-20M with the multi-spectral capability of the SA-34. Resurs-F2 offered a ground swath of 150 km with a resolution of 5-8 m in six spectral bands from 0.40 micrometer to 0.86 micrometer. As many as 2,700 photographs with image motion compensation and frames 180 mm by 180 mm could be shot on a single mission. The SA-M was also linked to the SA-3R stellar camera which serves the same purpose as the Resurs-F1's SA-33.

Prior to 1991, Resurs-F2 spacecraft would normally maintain a mean altitude of between 260 km and 270 km, requiring only two orbital maneuvers per 30-day mission. Beginning with Resurs-F 10(21 May 1991), a new profile was chosen with mean altitudes between 225 km and 235 km but with a corresponding requirement to perform orbital adjustments more frequently, e.g., six times per mission. This pattern had previously been used primarily by the military topographic mapping satellites which debuted in 1981 and were flown at inclinations of 65 degrees and 70 degrees. The subsequent Resurs-F2 flights, Resurs-F 13 (21 August 1991) and Resurs-F 14(29 April 1992), were virtually identical to Resurs-F 10, both in character and duration. Resurs-F 17 (May-June 1993), the only Resurs-F2 of the 1993-1994 period, also followed this pattern.

  • Soyuz The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for fifty years, more than 240 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the 21st century, providing the only manned access to the station after the retirement of the shuttle in 2011. More...

Associated Launch Vehicles
  • Soyuz Russian orbital launch vehicle. The world's first ICBM became the most often used and most reliable launch vehicle in history. The original core+four strap-on booster missile had a small third stage added to produce the Vostok launch vehicle, with a payload of 5 metric tons. Addition of a larger third stage produced the Voskhod/Soyuz vehicle, with a payload over 6 metric tons. Using this with a fourth stage, the resulting Molniya booster placed communications satellites and early lunar and planetary probes in higher energy trajectories. By the year 2000 over 1,628 had been launched with an unmatched success rate of 97.5% for production models. Improved models providing commercial launch services for international customers entered service in the new millenium, and a new launch pad at Kourou was to be inaugurated in 2009. It appeared that the R-7 could easily still be in service 70 years after its first launch. More...
  • Soyuz 11A511U Russian standardised man-rated orbital launch vehicle derived from the original R-7 ICBM of 1957. It has been launched in greater numbers than any orbital launch vehicle in history. Not coincidentally, it has been the most reliable as well. After over 40 years service in Russia, ESA built a new launch pad at Kourou which will keep it in service from three launch sites in three countries well into the mid-21st Century. More...

Associated Launch Sites
  • Plesetsk Plesetsk was the Soviet Union's northern cosmodrome, used for polar orbit launches of mainly military satellites, and was at one time the busiest launch centre in the world. The collapse of the Soviet Union put the main launch site of Baikonur in Kazakh territory. It now seems that once the Proton rocket is retired, Baikonur will be abandoned and Plesetsk will be Russia's primary launch centre. Upgrades to existing launch facilities will allow advanced versions of the Soyuz rocket and the new Angara launch vehicle to be launched from Plesetsk. Plesetsk's major drawback was the lower net payload in geosynchronous orbit from a northern latitude launch site. However Russia is planning to remove the disadvantage by looping geosynchronous satellites around the moon, using lunar gravity to make the necessary orbital plane change. More...
  • Plesetsk LC41/1 R-7 launch complex. Code named 'Lesobaza', this was the first complex completed at Plesetsk, being declared ready for military service with the R-7A ICBM in November 1959. The complex followed the design of the protoype facility built at Area 31 of Baikonur and included its own residential area for military personnel and assembly buildings for launchers and payloads. More...
  • Plesetsk LC16/2 R-7 launch complex. Complex 16 was the second R-7A ICBM launch complex to become operationall at Plesetsk, in 1960. In 1969, Pad 2 was cannibalized to upgrade the Area 1 facility in Baikonur. Pad 2 was not again brought into operation until 1979. It was then completely renovated as a space launch pad for Molniya 8K78M/Soyuz 11A511U class vehicles. The first launch was on 19 February 1981, and it continued in use in this role into the 21st Century. More...
