         The world's first artificial satellite: Sputnik One.

       The former Soviet Union in October 4, 1957 launch of the world's first artificial earth satellite. (Спутник-1). Sputnik 1, mainly from the shell, satellite equipment and antenna. Satellite spherical, diameter 0.58 m, weight of 83.6 kg. Housing is made of two aluminum hemispheres butt made ​​with rubber parts remain airtight, internal filled with 0.12 MPa (1.3 atm) of dry nitrogen. The lower shell surface is a heat radiation surface of the control system; plus a top half-shell outside the insulating layer. Installing the battery pack within the housing, a radio transmitter, thermal control system components, switching elements, temperature and pressure sensors. Battery set comprises three silver-zinc battery. In the center of the rectangular tank battery pack work alternately placed two radio transmitters, operating frequencies were 20.005 and 40.002 MHz. 4 whip antenna weight 8.4 kg, length 2.4 to 2.9 m. The initial satellite orbital parameters are: perigee 215 km, apogee of 947 km; orbital inclination of 65; operation cycle 96.2 points. Satellites were running 92 days, flying around the Earth about 1400 turns. Sputnik 1, on 4 January 1958 reentry burned. The main items satellite probe comprises measuring 200 to 500 km altitude atmospheric density, pressure, magnetic field, ultraviolet and X-rays and other data. Satellite also carries experimental animals to investigate animal's ability to adapt to the space environment.
