Sumario:Highlights In-flight calibration of the MEDA-TIRS radiometer onboard the Mars 2020 mission. Novel procedure and algorithm for recalibration of IR detectors responsivity. Report of responsivity changes and evolution along the first 800 sol of the mission. Gravitational sedimentation of dust is the most probable cause of degradation. Accounting for responsivity changes is critical to maintain the reliability of TIRS.
