Today, a European rocket Ariane 5 is launched, carrying two probes to study the planet Mercury, the smallest planet in the solar system and closest to the sun.
The mission is called "Baby Colombo", which leaves from the Kourou base in French Guiana. The rocket carries two probes into the orbit of Mercury, one from the European Space Agency and the second from the Japanese space agency, during a 9 billion trip to kilometers.
"To understand the composition of the Earth, we must understand the composition of the other rocky planets of the solar system, but Mercury is" distinct from his brothers "for some unknown reason, says Alan Dorsonderam, a researcher at the Paris Observatory. To discover these mysteries, both probes have been equipped with 16 sophisticated scientific instruments.
The planet Mercury has a diameter of 4,879 km, a small planet compared to 12,756 km from the Earth.
Pierre Bosquet, program director at the French Space Agency, explains that Mercury is abnormally small. Scientists believe that this uniqueness makes her hit by a massive crime early in her life.
