Title Trajectory Anomalies in Interplanetary Spacecraft : A Method for Determining Accelerations Due to Thermal Emissions and New Mission Proposals Author(s) Francisco, Frederico Publication Cham, Springer International Publishing, 2015. Description XVII, 87 p. 27 illus., 3 illus. in color : online resource Abstract Note This thesis presents fundamental work??that explains??two mysteries concerning the trajectory of interplanetary spacecraft. For the first problem, the so-called Pioneer anomaly, a wholly new and innovative method was developed for computing all contributions to the acceleration due to onboard thermal sources. Through a careful analysis of all parts of the spacecraft Pioneer 10 and 11, the application of this methodology has yielded the observed anomalous acceleration. This marks a major achievement, given that this problem remained unsolved for more than a decade. For the second anomaly, the flyby anomaly, a tiny glitch in the velocity of spacecraft that perform gravity assisting maneuvers on Earth, no definitive answer is put forward; however a quite promising strategy for examining the problem is provided and a new mission is proposed. The proposal largely consists in using the Galileo Navigational Satellite System to track approaching spacecraft, and in considering a small test body that approaches Earth from a highly elliptic trajectory ISBN,Price 9783319189802 Keyword(s) 1.
