Launching of first ever artificial satellite of the Earth; physical study of the atmosphere; remained in orbit until January 4, 1958. This event began the space race by galvanizing interest and action on the part of the American public to support an active role in space research, technology, ...
Sputnik 1, launched on Oct.4, 1957, became the first artificial satellite to successfully orbit the Earth. It was a metallic sphere about 2 feet across, weighing 184 lbs (84 kg), with long "whiskers" pointing to one side, and stayed in orbit for 6 months before falling back to Earth....
When Sputnik 1 was launched in 1957, it was estimated that the satellite would stay in orbit for years as a symbol of Soviet power. Instead, the satellite de-orbited in only three months while the US launched the Explorer 1 satellite stayed in orbit for twelve years and the US launched ...
Sputnik 1 remained in orbit until January 4, 1958, when it burned up on reentering Earth's atmosphere. Ultimately, the launch of the first artificial satellite spurred many countries, including the United States, to pursue space initiatives that continue to this day. 2. First animals to ...

Sputnik 1 was launched on October 4, 1957 which make it the first artificial satellite to enter space and orbit the Earth. Sputnik stayed in orbit for three months until it re-entered the atmosphere and burned up. Answer and Explanation: ...
Sputnik’s official designation was “PS-1” or “Elementary Satellite 1” in Russian. The satellite was launched from what is now called the Baikonur Cosmodrome on Oct. 4, 1957. The 184.3-pound (83.6 kg) craft’s primary function was to place a radio transmitter into orbit around the ...
But when the crew had tried to return it to Earth a few days later, the spacecraft inadvertently went evenhigherinto orbit due to a computer glitch.When Sputnik finally left orbit in 1962, most of it was burned in the atmosphere, except for a little chunk that crash-landed in Manitowoc....

In the late 1950s, after the Soviet Union successfully put their satellite, Sputnik 1, into orbit, American fears over the Communist threat reached a new height. The U.S. was trailing badly in a competition that would come to define the next decade – the race to space. So on April 9...
