Title: Artificial Intelligence Support of the Rosetta Orbiter Science Operations
On September 30th 2016, the European Space Agency’s Rosetta Mission ended with the Rosetta Orbiter landing on the surface of the comet 67P/ Churyumov-Gerasimenko. While it is well known that this historic mission was the first mission to deploy a soft lander to a comet (Philae) and to escort a comet for two years, it was also a pathfinding space mission from the perspective of Operations and Computer Science in its usage of the Artificial Intelligence planning and scheduling software for early to mid-range science activity scheduling and data downlink scheduling.
I will first provide an overview of the Rosetta mission - including its over one decade journey to the 67P/C-G, and major science discoveries from the mission. I then describe challenging elements of the high tempo, multi-disciplinary Rosetta science planning process which incorporated diverse science, geometric, engineering, and resource constraints. The talk will then present how the ASPEN software was used in the Rosetta operations process to support development of schedules for planning periods of approximately one month covering thousands of observations, over a thousand pointings and slews, over a thousand recorder dumps, and requiring verification of tens of thousands of science and operations constraints.
