However, on October 4, 1957, the Soviet Union shocked the United States and the world by successfully launching Sputnik 1, into orbit around the Earth, becoming the first nation to launch an artificial satellite into orbit, and pushing them to the front of the now active Space Race (Green and Lomask, 22). Sputnik I circled the Earth once every 96 minutes, was 22 inches in diameter, and was made of aluminum alloys.
The reaction in the United States was tumultuous, at best.
Citizens of the United States, once certain American's were superior in all things technological and scientific, now began to doubt the superiority of their educational system, as the Russian technologies advanced beyond American capability (Hayes, 13F). The night of the launch, however, only amateur astronomers seemed genuinely interested in the Russian achievement. As the implications of such advanced technology spread, however, so did panic and alarm, even though the government had known for some time the Russian military had capabilities of launching such a satellite (Eisenhower, 206). Citizens, however, surprised at the achievement and entrenched in the Cold War, feared the implications of such technology (Witkin, 4).
While the American public was in fear of the Russian accomplishment, those scientists involved in the failed Vanguard project were anxious to track the Russian satellite. Within hours of the launch, most of the orbit computation experts working on Vanguard had assembled to convert the Sputnik frequency to calculate and predict the course of the satellite. However, as the tracking system came online, Sputnik ceased transmission (Smitherman, 362).
Citizens of the Soviet Union, however, were greatly interested and excited about the Sputnik project. Realizing the world-wide recognition of their achievement, the citizens rallied behind the space effort, seeing the launch as an important sign of scientific and engineering capability. Considering the country was recovering from massive devastation after World War II, the Soviet's considered the launch a major milestone in their history (Witkin, 18B).
The Soviet Union again surprised the world on November 11, 1957, when they launched Sputnik 2. Not only was Sputnik 2 more advanced than its predecessor, the spacecraft also carried the first biological creature to be monitored in space. Standing 4 meters high, with a diameter of 2 meters, Sputnik 2 contained several compartments for radio transmitters, scientific instruments, and a temperature control system. Another compartment carried the experimental dog Laika. Laika was a female Samoyed terrier, and was held in a pressurized, temperature controlled area with enough room to lie down or stand. The compartment also held an air regeneration unit, and food and water. Laika was fitted with a harness, a bag to collect waste, and electrodes to monitor health conditions, which were then sent to Earth every fifteen minutes of each orbit. Although Laika was expected to die, since there was no way to return the craft to Earth safely, the dog perished only two days into the mission. Core separation did not occur on the craft during orbit, damaging the temperature control system and tearing the thermal insulation in the craft. Laika died from heat exposure. However, the data transmitted was the first of a living mammal in space. The craft reentered Earth's atmosphere in April of 1958 (NASA, 1957-002A).
The successful launch of yet another Soviet satellite provided the incentive needed by the U.S. Vanguard group. On December 6, 1957, Vanguard TV-3, a rocket carrying a small aluminum satellite was launched, but exploded within seconds. Shortly thereafter, however, on January 31, 1958, a Redstone missile was used to launch the first U.S. satellite, Explorer I, into space. The satellite carried with it instruments to study micrometeorites and cosmic rays. The satellite successfully showed radiation trapped in the Earth's magnetosphere, leading to the term the Van Allen Radiation Belt, named after the scientist studying the cosmic rays (NASA, 1958-001A).
While the Explorer launch was a success, the United States was still clearly losing the Space Race, as shown by several failed attempts shortly after Explorer. In an effort to improve the space program, President Eisenhower called for a civilian National Aeronautics and Space Agency (NASA, #10). Shortly thereafter, the NASA bill (S-3609) was introduced into the Senate and the House, with objectives listed of space exploration and manned space flights (NASA, #10).
While the concepts were certainly timely, their introduction was not. On May 15, the Soviet Union launched Sputnik III, a 2926 pound conical satellite capable of carrying...
All these life saving technologies are indeed very useful today and it's not easy to imagine them resulting from the NASA research. The eye tracker technology is one of the marvelous technologies which have made the world of the disabled people to be open up in particular those having impairment in speech and movement. The view's precise gaze point is distinguished at the computer screen through the tracking of
John Le Carre's classic spy novel, The Spy Who Came in from the Cold, is set in 1963 at the height of the Cold War. The novel's protagonist, Alec Leamas, is a seasoned and distinguished British agent who has come to have significant and important reservations about the morality of his job after he loses an agent in the field. Due to the ever-louder rumblings of his conscience, he returns
Space Program When the Soviets successfully launched Sputnik I, the first ever artificial satellite, in orbit on October 4, 1957, the event took the Americans and the entire western world by surprise. Sputnik I was just a 2-foot sphere with nothing more than two tiny radio transmitters on it, but the symbolic significance of the event -- the implication that Communist Russia had taken a significant technological lead over the United
Race and U.S. Imperialism When analyzing European imperialism (particularly that which occurred within the United States) it is crucial to note the role that race played in it. There is evidence that indicates that at one point, race itself became more of a factor in the justification of imperialism and the institutions which facilitated it and engendered its success than even religion did. Race was principally used to account for a
Race and Cultural Minorities Two centuries ago, Washington and Dubois debated the concept of race, a social construct based on an imagined demarcation that separated one group of human beings from another. Even then, the nuanced paradox of falsehoods and importance were at play; what seemed like a clear difference between some skin colors and ethnic groups was muddied in others, and the socio-cultural ends met by nominal means were indisputable.
Essed notes the profound perceived threat to power experienced by those in the majority feel when even small encroachments are made by other groups into the dominant fabric of society, and how tacit racism against minorities is often allowed even by those who might not consider themselves prejudiced on an interactional and personal level (184). In short, the institutional racism of society inevitably affects interpersonal relations, even amongst people
