Abstract

The Perseverance rover of NASA’s Mars 2020 mission carries a pressure sensor (PS) provided by the Finnish Meteorological Institute (FMI). The sensor belongs to the Mars Environmental Dynamics Analyzer (MEDA), a set of environmental sensors designed to characterize the near-surface atmospheric conditions. MEDA PS is based on the same Vaisala sensor and measurement technology as the pressure sensor of the Curiosity rover, but utilizes newer-generation sensor heads. The sensor has been calibrated in the pressure range of 0–14 hPa and temperature range from −45 to ＋55 °C. The calibration is based on tests performed in FMI’s pressure calibration laboratory, as well as measurements done after integration to MEDA and the rover. Since February 2021, MEDA PS has operated flawlessly on board Perseverance, delivering regular measurements of the local atmospheric pressure in Jezero crater. According to the evaluation based on the first 530 sols, MEDA PS is found to provide high-quality data with performance meeting expectations.

火星2020毅力号探测器的压力传感器

美国宇航局2020年火星任务的毅力号探测器携带由芬兰气象研究所提供的压力传感器(PS)。该传感器属于火星环境动力学分析仪(MEDA)，这是一套环境传感器，旨在表征近地表大气条件。MEDA PS基于与好奇号火星车压力传感器相同的维萨拉传感器和测量技术，但采用了新一代传感器头。该传感器的校准压力范围为0 - 14hpa，温度范围为- 45 ~ +55℃。校准是基于在FMI的压力校准实验室进行的测试，以及与MEDA和漫游者集成后进行的测量。自2021年2月以来，MEDA PS一直在毅力号上完美运行，定期测量耶泽罗陨石坑的当地大气压力。根据前530个sols的评估，MEDA PS提供了高质量的数据，性能达到预期。
