Abstract The international Rosetta mission was launched on 2nd March 2004 and after its ten year journey, arrived at its target destination of comet 67P/Churyumov-Gerasimenko, during 2014. Following the January 2014 exit from a two and half year hibernation period, Rosetta approached and arrived at the comet in August 2014. In November 2014, the Philae lander was deployed from Rosetta onto the comet׳s surface after which the orbiter continued its approximately one and a half year comet escort phase. The Rosetta Science Ground Segment׳s primary roles within the project are to support the Project Scientist and the Science Working Team, in order to ensure the coordination, development, validation and delivery of the desired science operations plans and their associated operational products throughout the mission., whilst also providing support to the Principle Investigator teams (including the Philae lander team) in order to ensure the provision of adequate data to the Planetary Science Archive. The lead up to, and execution of, the November 2014 Philae landing, and the subsequent Philae activities through 2015, have presented numerous unique challenges to the project teams. This paper discusses these challenges, and more specifically, their impact on the overall mission science planning activities. It details how the Rosetta Science Ground Segment has addressed these issues in collaboration with the other project teams in order to accommodate Philae operations within the continually evolving Rosetta science planning process.

    Highlights Planning Rosetta science observations in support of the Philae landing is discussed. Challenges to incorporate Philae in the wider Rosetta science planning are discussed. Evolution of Rosetta science operations planning based on mission experience. Adapting Rosetta science operations planning to incorporate Philae following wake-up. ESA׳s Planetary Science Archive activities with respect to the Philae mission.
