Artikelbeschreibung des Verkäufers

[2], iii, [1], 103, [1] pages. Illustrations. References. This was prepared under the sponsorship of the Douglas Aircraft Company Independent Research and Development Program. This is an early work associated with understanding aspects of Mars exploration. Mars is the fourth planet from the center of the solar system, orbiting the Sun once every 687 (Earth) days at a mean distance of 141 million mi (227 million km). Called the "red planet" for its distinct orange-red color, Mars has been the object of intense interest for over a century. Mars was thought to be barren after the Viking spacecraft landed on it in 1976 and found no evidence of living organisms. But interest in Mars as at least an ancient host of life resurged in the 1990s with the claim of fossilized microbes in meteorites from Mars, and pictures from the 1997 Pathfinder mission that suggested water once swept across the Martian surface. Mars has numerous earthlike features. There are large, extinct volcanoes dotting its surface, eroded channels where water once flowed freely, and ice caps covering its poles that look very much like Earth's polar regions. But, the thin Martian atmosphere is made mainly of carbon dioxide. Although Mars may now be a cold, dead world, the variety of features on its surface suggests a complex and fascinating past. The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas, Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas. Douglas Aircraft Company largely operated as a division of McDonnell Douglas (MD) after the company mergers. MD later merged with Boeing in 1997. The United States Army Air Forces established 'Project RAND' (Research ANd Development) with the objective of looking into long-range planning of future weapons. In March 1946, Douglas Aircraft Company was granted the contract to research on intercontinental warfare. Project RAND later become the RAND Corporation. Douglas continued to develop new aircraft, including the successful four-engined Douglas DC-6 (1946) and its last propeller-driven commercial aircraft, the Douglas DC-7 (1953). The company had moved into jet propulsion, producing its first for the U.S. Navy — the straight-winged F3D Skyknight in 1948 and then the more "jet age" style F4D Skyray in 1951. Douglas also made commercial jets, producing the Douglas DC-8 in 1958 to compete with the new Boeing 707. Douglas was a pioneer in related fields, such as ejection seats, air-to-air missiles, surface-to-air missiles, and air-to-surface missiles, launch rockets, bombs, and bomb racks. The company was ready to enter the new missile business during the 1950s. Douglas moved from producing air-to-air rockets and missiles to entire missile systems under the 1956 Nike missile program and became the main contractor for the Skybolt air-launched ballistic missile program and the Thor ballistic missile program. Douglas also earned contracts from NASA, most notably for designing the S-IVB stage of the Saturn IB and Saturn V rockets.…
