The present-day approach to selecting missions for solar system exploration is based largely on the price-performance ratio – getting the most for the least within an acceptable level of risk. Mission analysis plays an enormous role in this process as mission designs become ever more complex to qualify under the selection criteria currently being applied. The hugely successful Cassini mission to Saturn has set the bar for the level of complexity in mission design, but this distinction is temporal as the Messenger mission engages in its lengthy and circuitous path to its final destination in orbit about Mercury, preceded by several swingbys of Earth, Venus, and Mercury and major space burns.
As the tools and methodologies for the analysis of such missions are refined, increasingly elaborate mission designs are to be expected and demanded. This three-day course is designed to prepare engineers and technical management for the task of adequately planning and supporting the mission analysis function to successfully accomplish its role in a solar system exploration project. Mission Analysis for Solar System Exploration Training also provides the background and direction needed for those interested in mission analysis to pursue their craft in an organized and expeditious manner.
