Fact about sputnik

Sputnik 1 was launched into earths orbit on October 4th 1957. It was the first man made satellite and was made by the Soviet Union. To put sputnik into space the soviets used a powerful

rocket to launch it high above Earth and shoot it to the ground at a very high speed. It's primary purpose was to send back

temperatures of space. It did so in the form of beeps. Sputnik weighed 405 lbs, and It's diameter is 23 inches across. Sputnik was in orbit around the earth for 3 months after it's launch in

1957. Then after it's 3 month journey in space it burned up in the atmosphere. It was a very big step that launched the space race.

Out coming

There was another lucky outcome of Sputnik. Two years earlier, President Dwight D. Eisenhower had proposed

"Open Skies," under which the United States and Russia would permit spy-plane over flights so each would know the other's military capabilities. The idea was to reduce mutual uncertainty and strengthen deterrence. Soviet leader Nikita

Khrushchev rejected the idea out of hand.
