Two satellites developed in Europe and Japan went to Mercury, the planet closest to the Sun.
Duet has called BepiColombo he left Earth on an "Ariane" rocket, which was launched from South America. It will take 7 probes to reach the destination. When they arrive at Mercury and begin their parallel observations, we can discover many secrets of the small hot world.
The origin of Mercury is a question that many want to answer. It is possible that Mercury began life far farther from the Sun and only later migrated to it, probably encountering something else in its path.
Mercury can be reached in a few months, but the speed that the spacecraft will take due to the strong gravity of the Sun will make it very difficult to stop the planet.
Bepi it will follow a more indirect way. It will fly beyond the Earth, Venus and Mercury itself, using the capture of their gravity to slow down. By 2025, the mission will enter the orbit of this small planet.
There, a duet of equipment awaits a terrifying warmth. Mercury is only 58 million km from the Sun, so working on the planet is like working on a hot pan. The probes face temperatures above 400 °C. Even surfaces that look away from the Sun must be protected from the heat that will come from the planet. MMOs, for example, will be closed with titanium and ceramic insulating material.
