NASA’s Mars 2020 mission successfully launched to Mars July 30, 2020. An on-orbit contingency plan was developed to accomplish a controlled re-entry of the spacecraft in the event of a launch vehicle anomaly. The entire launch period was assessed, and satisfactory de-orbit burns were designed for every launch opportunity. An operational implementation was created for rapid adoption if needed, and validated using information from the Gravity Recovery and Climate Experiment (GRACE) satellites. This paper presents the orbit determination models and filter strategies used to conduct the pre-launch analyses, as well as the operational implementation validation methodologies and results.
