Haley Ruble Professor Royas ARO 102 Section 1 3 February 2020 Week One Summary On October 4 th , 1957 the Soviet Union launched Sputnik 1, the first artificial satellite to go into orbit around the earth. Twelve years after that people walked on the moon, then 7 years after that unmanned probes rested on Mars and Venus. Velocities of 26,000 feet per second are needed to get a vehicle into earth's orbit and 36,000 feet per second to overcome the gravitational attraction and travel into space. July 20 th , 1969 was the Apallo Lunar mission to the moon. Lagrange's equations reduced the aspects of mechanics into a few general equations. On October 1957 three Vangard rockets were tested at Cape Canaveral and succeeded. On December 6 th , 1957 the actual launch of the Vangard 1 failed, it lifted a couple feet in the air then fell back down and exploded. On January 31 st, 1958 the Explorer 1 was the first US artificial satellite in orbit by Von Brauns team in Huntsville with an apogee of 957miles and a perigee of 212 miles. In 1930 Frank Whittle from England patented a design for a gas turbine, then 1937 April 12 th was the first jet engine test in the world to successfully operate, but not the first to fly. Hans Von Ohain from Germany designed a similar gas turbine engine and le w it for the first time on August 28th, 1939. Ohain paired with Heinkel o builds airplanes, which was named He 178. Germany was the first nation to have military jet engine aircrafts.
