The BepiColombo space probe managed to discover a dynamic and changing environme around the planet Mercury during its closest pass. During its closest flyby of Mercury earlier this moh, the probe captured the first clear image of the planet’s south pole, and in addition collected valuable data showing the rapid and significa changes in Mercury’s local environme in response to It is the solar wind.
According to Tekna Technology Media Astronomy News Service, on September 4, BepiColombo made its fourth successful transit of Mercury. The close flyby slowed the joi Europe-Japan probe and changed its direction, bringing the spacecraft closer to its ultimate goal of eering Mercury orbit in 2026. Preliminary analysis of data collected by ten of the probe’s sixteen scieific instrumes shows that the environme around Mercury is significaly differe and sometimes exhibits unexpected characteristics. Members of the mission team preseed the findings at the Europlanet Science Congress in Berlin last week.
Although BepiColombo had passed through the same regions around Mercury on its previous three flybys, the probe’s science instrumes recorded differe numbers of particles in the bubble-like magnetosphere created by the planet’s magnetic field. Hailey Williamson, Senior Scieist at the Swedish Institute of Space Physics and one of the principal investigators of the SERENA instrume on the BepiColombo probe, stated in this regard.
On September 4, during the probe’s closest flyby of Mercury’s surface at a distance of 165 km, BepiColombo managed to detect planetary ions for the first time. These ions are charged particles that are thrown io Mercury’s magnetosphere after the solar wind hits the surface of the planet and as a result. Surprisingly, these particles split io two differe energy levels immediately after the probe’s closest approach to Mercury, Williamson said. In general, the results of these transits show that the magnetic environme of Mercury had significa differences in each transit.
“All the data collected from these passes are completely differe from each other,” Williamson said. These findings clearly show that the space environme around Mercury is very dynamic and variable. A day before the BepiColombo probe’s closest pass, the spacecraft and the planet Mercury were hit by a strong stream of energetic solar particles. These particles have a significa effect on the planet’s magnetosphere and may explain some of the unexpected features observed in the data. However, to reach a definitive conclusion, more studies and analyzes are needed.
Ignacio Clerigo, the BepiColombo spacecraft operations manager at the European Space Agency (ESA) in Germany, announced that the probe’s latest close pass was the closest a spacecraft has ever made around a planet, including Earth. He appreciated the valuable efforts of the flight corol and mission dynamics teams who successfully executed this complex eve. This eve was done with a distance of 35 kilometers less than the original plan. Clerigo considered this achieveme a great engineering success.
