ABSTRACT
Space Weather profiling is the concept of modeling the changing environmental conditions in near-Earth space in the form of a mathematical model. Solar Activity, Inconsistent variations in radiation level, total electron count, water vapor profiles are some of the parameters measured using the on board devices of the micro-satellite that we shall be discussing here. The module consists of a Geiger Muller Tube/counter, a Radiometric IR camera and a GPS Receiver. The Geiger Muller Tube takes radiation readings when there is ionizing radiation incident on its mica window. The radiation reading is in the form of dose rates. The second device i.e. the Radiometric IR Camera takes a thermal image of the temperature fluctuations because of this ionizing radiation. The data from these two devices are then plotted onto the same map to give 3D Predictive Model of radiation which can then be extrapolated depending on our purpose. The GPS receiver takes in the signal from the GPS satellite which passes through the atmospheric limb path and it’s bending takes place due to the various factors like change in pressure, temperature, water vapor, TEC. The angle of bend can be measured to obtain the profile of these factors causing the bend by using Abel transforms and other mathematical models. The data collected from the

    Vanguard Project History

    Lyndon B. Johnson, Senate preparedness Subcommittee chairman, immediately began a “full, complete, and exhaustive inquiry into the state of the nation’s satellite and missile efforts (Lyndon B. Johnson quoted in Vanguard – A History).” The Vanguard project had received ultimate priority in military initiatives and, as a result, received a needed boost in men, materials, and money. This drastic increase in effort on the part of everyone involved had culminated in greater testing and development of Vanguard project rockets. Despite multiple failures throughout 1957 and 1958, their efforts culminated in a successful launch on January 31st, 1958. Explorer 1 left the launch pad at cape Canaveral and, at last, the United States had proven their worth in space exploration (Office of the Historian). Despite their eventual success, the political ramifications of “losing” the first milestone of the space race were lasting. The United States had developed newfound conviction in the space race, now aware of their adversaries’ potential; additionally, the creation of NASA had cemented space exploration’s place in the US government and budget. The United States’ delayed reaction, only prioritizing space exploration after the Soviet display of their technology, highlighted the competitive nature of the nation. Had the Soviets not succeeded…

    U. S. Space Program: The Triumph of Appolo 13

    America has always taken great pride in its successes and accomplishments in science and technology; its claim of superiority is indisputable and evident with the continuous scientific discoveries and constant advancement of electronic gadgets. However, according to Burton Diche, during the 1950s and 1960s, "the American space program had absorbed a series of high-profile embarrassments as the Soviet Union, with which the U.S. was competing in a so-called Space Race, seemed to remain one step ahead."1 Yet, instead of accepting defeats, America demonstrated its power to the Soviets and the world by the extraordinary triumph of the first moon landing in 1969. In order to fully appreciate the significance of the lunar landing of Apollo 11, one must review the history of the early U. S. space program, from its inception to the successful completion of the Apollo mission.…

    The Birth Of The Space Race By Wernher Von Braun

    The birth of the Space Race commenced long before the Cold War tensions began to rise. In the 1920’s Wernher Von Braun was a German teenager who dreamed of designing and creating rockets capable of reaching outer space. He spent his high school years participating in “Verein für Raumschiffahrt (Society for Space Travel), which conducted experiments with liquid fuel rockets.” Following high school Von Braun joined the Nazi Party who capitalized on his expertise with aerospace engineering. He became a leader of the ballistic missile development program, “there he oversaw the design of the V-2, the first long-range ballistic missile developed for warfare. The “V” in V-2 stood for Vergeltungswaffe (vengeance weapon).” The long range destructive…

    Apollo Program History

    Amidst the shortcoming of the Cold War, the goal of the 1960’s was “to go above and beyond” in space exploration by successfully landing a man on the moon, which would serve as a gambit to conceivably lead the United States to victory. Before astronauts ventured beyond the earth, scientists had to assess the space environment and the hazards of human exploration. Soon after President John F. Kennedy assumed office in January of 1961, the space race was undoubtedly underway, and the United State’s primary focus was landing a man on the moon--hence, the Apollo Program. These Apollo Missions are significant in that America received technical credibility and hasted the end of the Cold War in our favor. Also, Carole Stott, a long-time astronomer…

    ENG 122 Final Paper

    According to Steven J. Dick (2008) in The Birth of NASA, Russia’s launch of the Sputnik satellite in October of 1957 was a source of embarrassment for America. America saw itself as a “leader in aeronautical and space science and technology” and Russia beating them to space was a slap in the face. The National Aeronautics and Space Administration (NASA) was born July 29, 1958, at the direction of President Eisenhower. At its outset, some of NASA’s objectives included providing national defense agencies with discoveries that would aid in national defense, reestablishing America as the preeminent technological leader of the world and peaceful cooperation between the U.S. and other nations in pursuit of shared goals (para1-9). Today, with the shuttle program gone, and with NASA’s budget getting ever smaller, these original mandates are getting more and more difficult to fulfill. As a result, America is in danger of losing its position as the preeminent leader in space exploration and technological advancement. This paper will be an examination of reasons why the U.S. should continue to fund space exploration despite other problems in the world today.…

    The Cold War: The Space Race

    The final act in the space race was when the United States put a man on the moon, beating the Soviet Union who had started the space racy by launching the first satellite called Sputnik. In an attempt to land on the moon the Soviet Union failed four times between the years of 1969 and 1972. The entire world's attention was taken over throughout the Space Race, also the multitude of scientific discoveries by both the United States and Soviet Union's space programs were covered almost every day in the media. After the Space Race Soviets were pictured as villains around the world, with their many attempts to beat American democracy and show how powerful the communist party is. After the Space Race had ended the world's interest in space had begun to fade. But in an attempt to show the ever improving United States-Soviet relationship, in 1975 the two countries combined through the Apollo-Soyuz mission and sent three American astronauts into space aboard an Apollo spacecraft which then met up in orbit with a Soviet-made Soyuz vehicle. When the commanders of both spacecrafts met each other, their handshake symbolized the overall improvement of United States-Soviet relations after the Cold War had…

    Cold War: The Space Race

    On April 23, 1967, the Soyuz 1 was sent into orbit. This space craft was carrying the cosmonaut Vladimir Komarov. The Soyuz 1 was supposed to be sent into space, stay there, and then another space craft, Soyuz 2, was going to rendezvous the Soyuz 1 and then dock. This did not happen. One of the solar panels on Soyuz 1 space craft was damaged. Although Russia knew that Soyuz 1 still had problems, the government overruled the engineers and launched it anyway. Russia planned on sending Soyuz 2 to fix the solar panel the next day but, a heavy rain the made it impossible for that to happen. When the space craft passed over Russia, Vladimir Komarov decided to try and fall to Russia and deploy a parachute so it would land safely. He tried this plan and during the descent the parachute failed to deploy and it fell into a field at 4,000 mph. Afterward there was a state…

    Space Race Essay

    The first landing on the moon was an incredible milestone for humans. It marked the end of the Space Race, the creation of advanced technologies, and the unification of the USA. The start of the space race saw the Soviet Union take a giant head start over the United States of America with the successful launch of Sputnik, a Soviet Union satellite launched on October 4th, 1957. The Soviets also launched Sputnik 2, which contained a live passenger, but the passenger died due to the overheating of the cabin and Sputnik 2’s batteries died after only 6 days in space. The US attempted to catch up to the Soviet’s progress with the attempted launch on December 6, 1957, of the Vanguard.…

    Space Race

    On October 4, 1957, the Soviet Union launched the first satellite into space, The Sputnik I. This was detrimental to the U.S. because it meant that they were losing the space race. The Soviets showed the U.S. that they now had the capability to launch satellites and nuclear warheads into space. America quickly answered back with the launch of Explorer I, which was the first American made satellite to orbit around Earth. This achievement by the U.S. led Eisenhower to form the National Aeronautics and Space Admission (NASA). The organization was founded to study and build space exploration vehicles and scientific experiments. Soon after the formation of NASA, the Soviets launched the first man into the orbit of Earth, heating up the space race. Nearly a month later, NASA launched Alan Shepard into space, making him the second man to exit Earth’s atmosphere.…

    The Space Race

    The USSR's first space program was the Sputnik, which had as many as twenty- five launches. Out of the twenty-five, there are two milestone launches in which the the Soviet Union showed their obvious superiority to the US. The first milestone launch in the Sputnik program was Sputnik 1, which was the world's first artificial satellite to reach space. The launch of Sputnik 1 on October 4th, 1957 was the first big step in the space race and demonstrated the USSR's advanced technical abilities. " Sputnik 1 was about the size of a basketball, weighed 183 pounds and orbited the earth in only 98 minutes"(Siddiqi). Two months after the launch of Sputnik 1, the United States tried to match the Soviet Union by launching their own satellite, but their attempt failed. "Oh What a Flopnik,"(Garber). This was reported in the London Daily Herald after the US's first attempt to launch a satellite. This shows that the US tried to match the USSR's launch but could not. With the launch of Sputnik 1, and the failures of the US's first launch, the USSR proved to be technologically superior to the US at the…

    What Is The Negative Effects Of The Space Race?

    October 5, 1957; this is the day that went down in history as the day the Space Race between the United States and the USSR began. On this day the USSR successfully launched the Sputnik satellite into orbit around the planet. Close to a month later the USSR launched the Sputnik 2 which held the first living organism to orbit the planet; Laika the dog. The series of events that followed brought change to the Cold War and to the world that could not have been foreseen in terms of international relations. During the Cold War the balance of power, globalization, perception, and nationalism all came into question, especially looking at the effects of the Space Race.…
