Sam Wagner Doctor of Philosophy in Aerospace Engineering Iowa State University *** Since the launch of Sputnik 1, on Oct. 4th, 1957, the human race has been driven by curiosity to explore beyond Earth and enter into the solar system. NASA’s Mariner 2 spacecraft, launched on Aug. 27th, 1962, was the first successful interplanetary space probe, passing within 22,000 miles of Venus. Since then a myriad of spacecraft have been launched in an effort to explore our solar system, although only a fraction of our solar system has been explored. To further explore the solar system larger spacecraft and scientific payloads will be required. These missions can only be enabled through increasingly complex trajectories, often by the use of a combination of planetary gravity-assists, deep-space corrections maneuver and, more recently, low-thrust solar electric propulsion.
