Resumo

The MESSENGER spacecraft completed more than 4000 orbits around Mercury during 4 years of operation on orbit around the planet. Using the onboard magnetometer data, we determine the bow shock and magnetopause crossings in Mercury’s magnetosphere by automatic methods and compare the accuracy of these methods with the results of manual data processing. The developed algorithm makes it possible to significantly increase the magnetometer data processing rate and can be used in the future when analyzing data from the BepiColombo spacecraft, which is going to enter Mercury’s orbit in 2025.
