With the focus on terror-based groups and the Middle East over the last fifteen years, many in the United States (US) are unfamiliar with the threat more conventional nation-states pose to the country’s national security. China, Iran, and Russia are seen as the three biggest threats to U.S. national security. Although Russia does not dominate the intelligence disciplines of HUMINT, OSINT, and cyber, its strengths in SIGINT, IMINT, and MASINT make it the biggest threat to the US. HUMINT Russia’s

whole race started on October 4, 1957, when the first Sputnik was launched. This satellite weighed about 184 pounds and the official name of it was "Iskustvennyi Sputnik Zemli" (1). Which meant "fellow world traveler of the earth". To counteract the United States’ launch of the Explorer 1, a satellite that included a rocket motor, the Russian’s responded with Sputnik 3 on May 15, 1958. The first three Sputnik satellites all carried instruments to measure the temperature and density of the earth’s upper

Space Debris In 1957, the first artificial earth satellite Sputnik 1 was launch into space [1]. Humans entered the space age. With the development of the space industry, more and more orbital debris is produced. It is becoming a potential hazard now. Increasing amount of space debris attracts each country’s attention. Space experts are trying to find the way to reduce and eliminate the amount of orbital debris. This paper first illustrates what space debris is, the size and the amount of space debris

RADARSAT-1 was a satellite launched by the Canadian Space Agency (CSA) in 1995 that incorporated a synthetic aperture radar (SAR) sensor operating in the C-band (frequency of 5.3 GHz). RADARSAT-1 stopped transmitting because of a technical problem in March 2013. The RADARSAT-1 images were ordered from the Alaska Satellite Facility website (www.asf.alaska.edu). The RADARSAT satellite was designed with seven SAR imaging beam modes. Each beam mode offers a different areal coverage (from ~50 km x 50

nuclear weapons. The space race continued when the Soviet Union launched the Soviet R-7 intercontinental ballistic missile launched Sputnik. The Soviet R-7 was the world’s first artificial satellite and the first man-made object to be placed into the Earth’s orbit. In 1958 the United States launched a satellite named the Apollo 1. It was made by the US army with the help of a rocket scientist, Wernher Van Braun. That same year President Dwight Eisenhower signed a public order creating NASA, National

nuclear advances, and intel. The Soviet Union seemed to be advancing against the United States during the 1950s. Then the unimaginable happen, the Soviet Union was able to launch a missile into outer space which contained the world’s first artificial satellite. In the United States, Americans were surprised that the Soviet Union had accomplished such a task. They were also afraid since

favored. Small satellites, Nanosats, and CubeSats are proliferating universities, FFRDCs, government agencies, and commercial entities. This trend is flowing into organization charts, as well. New, agile organizational structures and partnering arrangements are perpetuating the metamorphosis. Small companies, incubators, venture capitalists funded businesses are designing, building, and incorporating smaller satellites, into their business plans. Distributed networks of small satellites require precise

Conclusion Satellite sensors send bits of binary data to ground stations on Earth for processing into useful meteorological and environmental information enabling enhanced decision making capabilities. Thereby, preventing injuries and fatalities, preserving assets, and reducing time delays. Binary data are comprised of zeroes and ones. One bit contains either a “0” or a “1”. A single bit, in and of itself, does not have a lot of value until it is used. The same is true of information. Information

Computer Science: An Open Field JT Raber Indian Valley High School  With computers, we went to the moon. With computers, are revolutionizing communication. With computers, we will become a utopia. The greatest technology of the modern world is computers without a doubt. Because this is the case, there are multiple career variants in the field of computer science, ranging from analog to digital, offline to online, and structured to creative. Digital graphic designers, software developers, web developers

One of the main challenges that face interplanetary travel is the production of very large velocity changes, necessary for travel between planets in the solar system. The Sun's gravitational pull affects how spacecrafts move. The farther from the sun the slower the spacecraft and the faster they are closer to the sun. Additionally, two planets have different distances from the sun and this causes a difference on their speeds around the sun. This therefore means that the spaceships traveling closer
