Shocking Discoveries on Mercury

The video explores the MESSENGER mission to Mercury, which lasted from 2011 to 2015. It highlights the spacecraft's achievements, including mapping Mercury's surface, studying its magnetic field, and discovering volatile substances. The video also explains Mercury's unique orbit and rotation, its dynamic magnetosphere, and geological features like the Caloris Basin. The findings have challenged previous solar system formation theories and provided insights into Mercury's exosphere. The video concludes with a look at future missions, such as the Beppy Colombo mission, set to arrive in 2025.
