In fact Russia was the first to jump into space. With the aim of equalizing or defeating Russia’s high flight, the USA launched its space program and launched Explorer-1. It was launched from Cape Canaveral, Florida. It was prepared in the US Processing Lab (JPL). Vanlan was the first to know about the radiation belt. This belt has small parts produced from solar wind that generate tremendous energy.
Two such belts have been found near the earth. It was named after its inventor, James Vanlan. This belt is at an altitude of about 30 km to 3000 km above the earth. Radiation levels here are low and high. In addition to the energy-generating divider Soltex wind, there are also global rays. The first U.S. satellite made a lot of data available to U.S. scientists. He continued to work in his classroom for about 15 years. Explorer-1 was given Satellite Catalog No. 4
Speaking of the Cold War between the US and Russia, let me tell you that Russia had already gained the upper hand in space and launched its Sputnik 1 and 2 into space before Explorer-1. The two then competed over how quickly the space could be occupied. This was the main cause of the Cold War.
The American Earth Satellite program was launched in 1954. He was named Project Observer. Earlier it was advised to use a red tone missile. But President Ahovanhover will not like this. So he adopted the Navy project. It was told to launch with the help of a booster. For this some necessary modifications were made in the Jupiter-C rocket. It was later renamed Juana. But it took a long time for the US to do all this, and on October 4, 1957, Russia launched its own satellites, Putrik-1 and November 3, 1957.
The main reason for the US’s anger with Russia was not the delay in its launch, but the failure of its first attempt. The shortage hit the world on December 6, 1957. The US satellite weighed just over 15 kg. The Russian satellite was much heavier than that. Juno-1 was replaced with Juno-2 in 1959.
