- W2331767461 abstract "The Dawn Mission to the main belt asteroids (4)Vesta and (1)Ceres presents unique challenges for science planning and operations. The uncertainties of achieving orbit around a substantial body with an unknown gravity field limit the ability of the mission designers to predict in advance the timing of geometric events and orbit parameters. Therefore the science plan architecture had to be robust to a large range of planning uncertainties. However, the complexity of instrument interactions with each other and with the spacecraft required that the science plan and instrument sequences be developed a year in advance of Vesta arrival. Because the science sequence planning and execution timeline did not allow for significant adjustments of the sequences prior to execution, and because the operations time at the asteroids was quite limited, the science plan was designed to be functionally redundant. Functional redundancy was intended to provide multiple observations of the same surface under different conditions. Observing in this manner was intended to protect against potential data losses while providing complementary datasets in the event that all data are successfully acquired. The Dawn spacecraft was captured into orbit around Vesta in July 2011 and will complete Vesta science operations in the summer of 2012. During the approach and early science operations phases there were multiple, unrelated incidents resulting in instrument datasets that were partially lost or degraded. Careful accounting of the datasets returned to date clearly illustrates how the data losses were successfully offset by the redundancy in the observation plan. One specific success is the framing camera stereo imaging from the High Altitude Mapping Orbit, which is needed to generate the topography map. This paper describes the results of the execution of the science operations plan and how that compared to the assumptions that informed the development of the plan." @default.
