The grating is accompanied by a comet detector

The European Space Agency succeeded in awakening on Earth the comet probe "Rosetta" who had been dormant in space for 31 months.

The "Rosetta" was launched into space in early March 2004 in order to study the "67P/Churyumov-Gracimenk" comet in Europe. The aviation bureau received a signal from Rosetta within 800 million kilometers at 6:17pm GMT on January 20.

Rosetta is equipped with gratings from HORIBA Jobin Yvon, the world's leading grating manufacturer. The grating also traveled with the probe for 10 years of space travel and will continue.

Why sleep for 31 months?

Because there is not enough power system, the detector can only use the gravity of the Earth and Mars, adjust speed and orbit 4 times, and arrive at the destination. In order to save energy, the detector entered the "hibernation" mode in June 2011.

Purpose: Uncovering the galaxy and even the origin of life The Rosetta detector is expected to arrive at the designated comet as soon as August 2014, when it will analyze the surface, gravity, shape and rotation of the comet, and find a suitable place to deliver 1 cubic meter. Mi-sized Philae lander.

Andrea Accom-azzo, director of the Rosetta detector program, said: “We really don't know much about this object.” Astrophysicist Mark McCaughlin said: “Open these 'time capsules' The composition of gas, dust and ice will provide important clues for the origin of the solar system and even the origin of life."

If all goes well, Rosetta will become the first human detector to orbit around the comet and put landers on the surface of the comet.
