Europe and Japan have sent a hardware duet to Mercury


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.

<p>	One of the key mysteries is the huge iron core, which accounts for 60% of the mass of Mercury. Science can not explain why the planet has only a thin outer layer of rock.</p>
<p>	The probes, which were combined for a long journey into the internal solar system, climbed above the Kuru spaceport in French Guiana at 10:45 pm on Friday.</p>
<p>	The European Space Agency (ESA) and the Japanese aerospace exploration agency send vehicles to Mercury for the first time. <em>Bepi</em> consists of two vehicles: the European Mercurial Planetary Orbiter (MPO) and the Japanese Mercury Magnetospheric Orbiter (MMO).</p>
<p>	The probes have different tasks. The MMO will study the magnetic field of the planet. Explore the behavior of the field and its interaction with the solar wind, the mass consisting of solar particles. This wind interacts with the super-rarefied atmosphere of Mercury, collecting atoms in the tail, which is transported into space.</p>
<p>	The MPO will map the terrain, determine the altimetric profile, test the interior of the planet and collect data on the surface structure and its composition.</p><div class=

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.
