The odyssey of Sputnik1, the first satellite in history | Digital Trends Spanish

On October 4, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite in history, from the Baikonur cosmodrome in Kazakhstan.

It was a shiny aluminum sphere, 58 centimeters in diameter, with four antennas 2.4 to 2.9 meters long.

Sputnik 1 had a mass of 84 kilos and inside it carried instruments that allowed it to measure the temperature of the outer layer of the atmosphere.

It also had two radio transmitters that were emitting a wavelength signal of 15 and 7.5 meters for three weeks until its battery ran out.

The beginning of the space age

The launch of Sputnik 1 was so important that with it, many consider that the space age began.

In fact, in the middle of the Cold War, its launch caused concern among the United States authorities who did not see in a very good way that an artifact built by the Soviets would pass over them and the rest of the planet several times a day.

Experts say that this fact made Americans reflect on their capabilities in the field of technology.

Sputnik 1 started the space race and encouraged investment in science and technology between the two blocks, which would last for several years and would have some historical events, such as the putting into orbit of Yuri Gagarin, and the arrival of States. United to the Moon.

For Sputnik 1 to become a reality, the engineer Sergei Korolyov had to convince the Soviet authorities, who preferred to promote the development of military missiles.

Korolyov spoke to the leaders of the bloc and explained that the Sputnik project would have a great impact internationally.

In all, Sputnik completed 1,440 laps around the Earth before disintegrating on January 4, 1958.

Since that historical moment, thousands of objects have been thrown into space and many of them have ended up as junk, what is now known as space junk.

Experts estimate that there are currently more than three thousand satellites in operation revolving around our planet.
