 U.S.S.R. 



"Big Science" Descriptor ; Space: solar and terrestlal physics 



Description of Facility/Instrument ; This Is a series of satellites 



specifically designed to foster cooperation between the U.S.S.R. 

 and Its allies as well as selected Western countries. The space- 

 craft primarily make studies of the upper atmosphere, although 

 two have been devoted to oceanographlc research.

Launched 



October 14, 1969, to study the effects of solar 

 ultraviolet and x-ray radiation on the structure 

 of the upper atmosphere. It carried equipment 

 from the U.S.S.R., the Democratic Republic of 

 Germany, and Czechoslovakia. 



December 25, 1969, studied the ionosphere, 

 electronic temperatures near the payload, and 

 electronic concentration between the payload 

 and ground receiving stations. It carried 

 Instruments from Bulgaria and Czechoslovakia. 

 The principal tracking stations included two In 

 Poland and seven in the U.S.S.R. 



August 7, 1970, studied the Interactions between 

 solar activity and the radiation belts of Earth, 

 and electromagnetic oscillations in the upper 

 Ionosphere. It carried Czechoslovaklan and 

 Soviet experiments. 



October 14, 1970, studied the effects of solar 

 ultraviolet and x-ray radiation. It had equip- 

 ment from the Democratic Republic of Germany, 

 Czechoslovakia, and the U.S.S.R.
