Class: Earth. Type: Magnetosphere. Nation: USSR. Manufacturer: OKB-1.

The Elektron mission was one of the earliest Soviet satellites to be authorized following the initial Sputnik series. The two spacecraft were designed to be deployed in a single launch of a Vostok booster. The spacecraft had the specific task of mapping the Van Alen radiation belts at higher inclinations than that achieved by US satellites of the time (60 degrees vs 30 degrees latitude). Decrees authorizing design and building of the Elektrons were issued on 9 May 1960 and 13 May 1961. Design work began in July 1960. Elektron B, with a design mass of 460 kg, was boosted into a high 450 x 60,000 km orbit to map the outer Van Allen belt, simultaneous with Elektron A's study of the inner radiation belt. To attain this orbit it used a perigee kick motor - a solid rocket of 3350 kgf and 12 to 15 seconds duration. Elektron B was 400 mm in diameter and 850 mm long. The spacecraft also measured cosmic rays and the upper atmosphere.


Specification

Total Mass: 444 kg.


Elektron-B Chronology


09 May 1960 Elektron satellite approved.

Central Committee of the Communist Party and Council of Soviet Ministers Decree 'On approval of work on the Elektron scientific satellite' was issued. The two spacecraft were designed to be deployed in a single launch of a Vostok booster. The spacecraft had the specific task of mapping the Van Alen radiation belts at higher inclinations than that achieved by US satellites of the time (60 degrees vs 30 degrees latitude). Design work began in July 1960.


13 May 1961 Soviet response to Apollo program Launch Vehicle: N1.

Soviet Decree 'On the Revision of Plans for Space Objects for Accomplishing Goals of Defence Designations--heavy boosters, course of work on Elektron, and suspension of work of work on the Kosmoplan and Raketoplan with continuation of new Raketoplan work' was issued. The decree set the end of 1965 as the date for the first launch of the N1. It also authorised Chelomei to stop work on Kosmoplan interplanetary probes and instead concentrate on a specific Raketoplan design - the LK-1 manned lunar flyby spacecraft.
