Rosetta was a European Space Agency (ESA) cornerstone mission that launched in March 2004, exited hibernation in January 2014, entered orbit around the comet 67P/Churyumov-Gerasimenko in August 2014, and escorted the comet through September 2016, executing the most detailed study of a comet ever undertaken by humankind. The Rosetta Orbiter had 11 scientific instruments (4 remote sensing) and the Philae Lander to make complementary measurements of the comet nucleus, coma (gas and dust), and surrounding environment. The ESA Rosetta Science Ground Segment (SGS) used a science scheduling system that included an automated scheduling capability to assist in developing science plans for the Rosetta Orbiter. While the automated scheduling was a small portion of the overall SGS as well as the overall scheduling system, this paper focuses on the automated and semi-automated scheduling software (called Automated Scheduling and Planning ENvironment - Rosetta Science Scheduling Component (ASPEN-RSSC)) discussing: 1) the scheduling and constraint checking capabilities of ASPEN-RSSC; and 2) how the software was used pre-exit from hibernation, prelander delivery, and escort phase of the mission; 3) challenges in using the software and lessons learned for future use of automated scheduling technology for future space missions.
