Elektron (redirected from Elektron (disambiguation))

Elektron 

a rarely used name for magnesium alloys. It was used in the 1920’s for the first industrial magnesium alloys based on the Mg-AI-Zn and Mg-Mn systems, which contained up to 10 percent aluminum, up to 3 percent zinc, and up to 2.5 percent manganese.

Elektron 

the name of a series of Soviet artificial earth satellites designed to study the earth’s radiation belt, cosmic rays, the chemical composition of near-earth space, short-wave solar radiation, galactic radio emission, and micrometeorites.

Elektron 1. Jan. 30, 1964	406	7,100	61	169
Elektron 2 . Jan. 30, 1964	406	68,200	61	1,360
Elektron 3 . July 11, 1964	405	7,040	60.87	168
Elektron 4 . July 11, 1964	459	66,235	60.87	1,314

Elektron 1 and Elektron 3 weighed 350 kg and had a diameter of 0.75 m and a length of 1.3 m; Elektron 2 and Elektron 4 weighed 445 kg and had a diameter of 1.8 m and a length of 24 m (see Table 1 for additional data). The measurements made by the Elektron satellites made it possible to study the time variations of the characteristics of near-earth space during various levels of solar activity. The Elektron satellites were launched in pairs using one launch vehicle.
