After the launch of Sputnik 1 in 1957, 1958 marked a significant escalation in the Space Race between the United States and the Soviet Union. The U.S. established the National Aeronautics and Space Administration (NASA) in July 1958 to coordinate its space efforts. Additionally, the U.S. launched its first successful satellite, Explorer 1, in January 1958, which discovered the Van Allen radiation belts. This year also saw increased public and governmental focus on science and technology education in the U.S. as a response to the perceived Soviet advantage in space exploration.
The USSR launched Sputnik on October 4th, 1957 and Explorer 1 was launched on January 31st, 1958--so the answer is 119 days.
Yes, both were launched from the Baikonur Cosmodrome.
The second satellite to be sent into Earth orbit was "Sputnik 2".
The first artificial satellite, Sputnik I, was launched by the USSR (Russia) in 1957. Following its launch on October 4, Russia launched Sputnik 2 on November 3. Sputnik 3 was not launched until May, 1958 following the US Explorer and Vanguard satellites in January and March.
The second attempt to launch Sputnik 3 was successfully done on may 15 1958.
Sputnik 1 - launched October 4 1957 (orbited until January 4, 1958)
Spunik 1 was launched on October 4, 1957 and stayed in orbit until January 4, 1958. Sputnik 2 was launched on November 3, 1957 and stayed in orbit until April 15, 1958. Further satellites in the series were Sputnik 3 in May, 1958, and the satellites referred to as Sputnik 4 and 5 (actually early Vostok capsules) in 1960.
Sputnik 1 was launched on the 4th of October 1957.
The US launched its first successful artificial satellite, Explorer 1 (Explorer I) on January 31, 1958. The USSR (Russia) had already launched two satellites, Sputnik 1 (October 4, 1957) and Sputnik 2 (November 3, 1957). But both Sputniks had been in lower orbits: the first burned up on reentry on January 4, 1958 and the second on April 14, 1958.
Sputnik 1 was never designed to land, approximately 3 months after it was launched it's orbit had decayed enough, that on the 4th January 1958 it burnt up as it reentered the Earth's atmosphere
EXPLORER 1, launched in February 1958, a desperate response to the 1957 Russian launch of Sputnik 1.
The first man-made object to successfully be placed in Earth orbit was dubbed "Sputnik". It was launched from the Baikonur Cosmodrome in Kazakhstan ... part of the USSR at the time ... on October 4, 1957.
