[2] In the early 1950s, Lockheed U-2 spy plane flights over the Soviet Union provided intelligence that the US held the advantage in nuclear capability.
[3][4] However, an education gap was identified when studies conducted between 1955 and 1961 reported that the Soviet Union was training two to three times as many scientists per year as the US.
The Juno I rocket that carried the first US satellite Explorer 1 was ready to launch in 1956, but that fact was classified and unknown to the public.
[6] The Army's PGM-19 Jupiter from which Juno was derived had been shelved on the orders of Defense Secretary Charles Erwin Wilson amid interservice rivalry with the US Air Force's PGM-17 Thor rocket.
Hours after the launch, the University of Illinois at Urbana–Champaign Astronomy Department rigged an ad hoc interferometer to measure signals from the satellite.
The same rocket that launched Sputnik could send a nuclear warhead anywhere in the world in a matter of minutes, which would strip the Continental United States of its oceanic defenses.
[10] Five days after the launch of Sputnik 1, the world's first artificial satellite, US President Dwight Eisenhower addressed the American people.
In the first and second days following the event, The New York Times wrote that the launch of Sputnik 1 was a major global propaganda and prestige triumph for Russian communism.
On October 9, 1957, science fiction writer and scientist Arthur C. Clarke said that the day that Sputnik orbited around the Earth, the US became a second-rate power.
[7] Research and development was used as a propaganda tool, and Congress spent large sums of money on the perceived problem of US technological deficiency.
[15] After the launch of Sputnik 1 national security advisers overestimated the Soviets' current and potential rocket strength, which alarmed portions of Congress and the executive branch.
Nikita Khrushchev, the Soviet leader, reflected on the event by saying, "It always sounded good to say in public speeches that we could hit a fly at any distance with our missiles.
[13] The week after Sputnik went up, we were digging ourselves out of this avalanche of money that suddenly descended.The launch spurred a series of US initiatives[17] ranging from defense to education.
[22] Though Kennedy did not favor a massive US crewed space program when he was in the US Senate during Eisenhower's term, public reaction to the Soviet's launch of the first human into orbit, Yuri Gagarin, on April 12, 1961, led Kennedy to raise the stakes of the Space Race by setting the goal of landing men on the Moon.
I don't agree with the label; but there can be no isolationists anywhere when a thermonuclear warhead can flash down from space at hypersonic speed to reach any spot on Earth minutes after its launching".
Former US Rear Admiral Rawson Bennett, chief of naval operations, stated that Sputnik was a "hunk of iron almost anybody could launch",[7] while former US Army general James M. Gavin described it as "the most significant military event of our time".
[23] The Sputnik crisis also spurred substantial transformation in the US science policy, which provided much of the basis for modern academic scientific research.
After the Sputnik crisis, leaders exploited an "awe doctrine" to organize learning "around a strong model of educational national security: with math and science serving for supremacy in science and engineering, foreign languages and cultures for potential espionage, and history and humanities for national self-definition".
[26] In Britain, the launch of the first Sputnik provoked surprise, combined with elation at experiencing the dawn of the Space Age.
