# Age a sphere of 58,5 cm (the same that a ball of basquete) and weighed 83,6 kg Had four antennas - two measured 2,4 meters and the others two, 2,9 meters.

# Sputnik left the Land in a R-7 rocket, that weighed four tons.

# Its function was to frequently send for the Land a 40 radio control of 20 and mega watts, easily caught for amateur radios.

# By means of the duration of the “beeper”, the technician Soviet had information on the temperature and the pressure in the space, beyond having the certainty that Sputnik had not been reached for no meteorite.
