History of the USSR Sputnik

The USSR Sputnik 1 was launched by the Soviet Union on October 4th, 1957. It became the first man-made artifact to be in outer space. Sputnik was the first small stepping stone into the new and innovative technology we have today.  The Sputnik 1 was a polished aluminium alloy sphere being 23 inches in diameter and 83.6 Kilograms in weight. It takes 98 minutes to fully orbit the earth. The satellite had 5 major jobs when being sent into orbit, most importantly being to test the placement of satellites in orbit of the atmosphere. The other reasons included providing information on the density of our atmosphere, testing the radio and different methods of orbital tracking, testing the effects of radio waves on the atmosphere and checking the principles of pressurization used on satellites, according to NASA. 

It all started with the Space Race between the United States and the Soviet Union lasting nearly 20 years. The Sputnik 1 was actually not the first to be built, Sputnik 3 was the first built but the last launched. The third was holding 12 instruments and was too heavy and intricate that they wouldn’t finish before the estimated time of the US, henceforth, the Sputnik 1 was created in a hurry to win the race. The sputnik 2 held a stray dog found on the streets of Moscow by the name of Laika. She was the first living creature to ever be in space from our planet, she lasted a full 4 days in space before dying due to the cabin overheating.
