Sputnik

Sputnik I was the first artificial satellite that went into Earth’s orbit. Sputnik I showed the world that the Soviet Union had an advance in technology. Sputnik I showed the world that you can launch rockets to outer space. Sputnik I and II were important to the world because it showed that you could send people up into space and that you could send rockets into space.

Sputnik I launched on October 4,1957, when Sputnik launched people thought that Sputnik wasn't going to last in space. People thought that Spunik woul fall back down to Earth. Sputnik I circled the Earth every 96 minutes. Sputnik I went at the speed of 18,000 miles per hour! Sputnik I weighed 184 pounds. Sputnik I made the world think differently. Sputnik I was the size of a basketball, it was really small compared to Sputnik II. Sputnik I was the first human-made object to orbit around Earth. Sputnik I was noticeable to see from the ground and people were surprised that you could see Spunik. Sputnik 1 stayed in Earth’s orbit for about six months before it fell back on Earth. Sputnik I made about 4,000 trips around Earth until it fell back on to Earth. Sputnik I fell on the Earth on January 4,1958.

About a month later, Sputnik II was launched, on November 3,1957 Sputnik II was launched. Sputnik II carried a dog inside, the dogs name was Laika. Laika was a female dog. Sputnik II was a lot bigger than Sputnik I. Sputnik II weighed 1,220 pounds while Sputnik I weighed 184 pounds. Sputnik II flew at a higher altitude. Sputnik II was a test to see if humans could go up into outer space. The test succeed, but a week later the oxygen in Laika’s cabin gave out. The Soviet Union did not have a way for Laika to get out of outer space so she sadly died in outer space. Sputnik II stayed in the orbit for 163 days before it decayed in April 1958.

Sir Bernard Lovell was an English astronomer. Lovell built the worlds first steer able radio telescope. The telescope could be pointed in any direction. Lovell was born on August 3,1913. Lovell studied physics at Bristol University. Lovell became well-known for making Sputnik. Sputnik I had a reflector of 250 feet in diameter. Sputnik I was 76.2 meters in diameter. Sputnik would focus radio waves on a receiver in the middle of the reflector.

Many historians believed that the Soviet Union launched Sputnik I to show military might and to improve the nations image. Sputnik I made technology by having satellites in Earth’s orbit to make televisions work. Sputnik I made technology by having radio and telephone satellites in Earth’s orbit. The launch of Sputnik I became a major blow to the United States.

Sputnik was important because it improved our technology. Sputnik made our technology better by making radio satellites so that we can listen to the radio. Sputnik also made television satellites come to life. If the testing of Sputnik never happened then we wouldn’t be able to listen to the radio and may even watch color television. Also if Sputnik didn’t launch then we wouldn’t have rocket ships. We wouldn’t also be able to visualize pictures of outer space and the planets.

This is a picture of Sputnik I.
