Essay / Research Paper Abstract
A 9 page paper that provides a history of unmanned space flight that has lead up to the Mars Pathfinder mission and the interrelationship of all of those missions to the eventual human habitation of another planets, namely, Mars. The quest for Mars was begun 40 years ago, and all of the space exploration to date, manned or unmanned, including discoveries about earth and the universe, have been made toward this purpose. Bibliography lists 7 sources.

it built the Explorer 1 satellite in 1958. The loss in 1993 of NASAs $1 billion Mars Observer," has been called "one of the most embarrassing failures in...40 years"
(Tonner, 1997, pp. A12). Pathfinder is only the latest in a long history of unmanned space flights. The information gleaned from early missions, rocket development, and the development of
satellites and probes, have given us knowledge in weather patterns, geology, black holes, pulsars, quasars, and knowledge of the sun and other planets in our solar system. The purpose
for all of this effort is to inhabit other worlds. Origins In 1909, both Great Britain and Germany had established aviation research
laboratories. America had not. In 1915, the National Advisory Committee for Aeronautics (NACA) was finally established. It was the same year Albert Einstein postulated his general theory
of relativity, Alexander Graham Bell made the first transcontinental phone call, and, a new speed record for automobiles was set at 102.6 MPH. The delay was caused by infighting
between the American Aeronautical Society, universities and the Navy, which was compounded by ambivalence on the part of the American public, who viewed aeronautics as a dangerous fad. (Billstein, Chapter
1). When long-range German dirigibles bombed English cities, the American air and space program began. In 1920, NACA technicians built a wind tunnel to test speed, followed by equipment for
testing pressurization, airflow, humidity and other variables in 1921, and supercharged engines and high altitude bombers in 1925. By 1927, radio communications had progressed, and NACA began to test
geometric airfoils that would become essential to the development of rockets, satellites, and space vehicles. By 1929, NACA developed low-drag cowlings and aircooled radial engines; increasing aircraft speed from
