Herschel and Planck satellites go into space in the Ariane-5 rocket

On board an Ariane-5 rocket, out of the European astronomical observation satellites Planck and Herschel, to inquire into the origin of the universe.

The departure of the shuttle from the Kourou base in French Guyana, occurred at 13:12 GMT without any complications, according to the European Space Agency (ESA).

Twenty-five minutes later, the satellite began its journey to reach its orbit, located approximately 1.5 million kilometers above the Earth, where they arrived in about 60 days.

The two satellites, designed by ESA, whose mission is to observe the universe to levels never reached so far, which may clarify the origin of it.

The fruit of 15 years of experimentation and more than 1,700 million euros (2,300 billion dollars at the exchange today) investment, the two telescopes will reach an equilibrium point between solar and terrestrial attraction.

Take a month and a half to get to that point, that will reach them independently.

Incorporating revolutionary observation instruments, Herschel and Planck are working in conditions of extreme cold, near absolute zero, to avoid distortions in their measurements.

This limits their lifespan, which is three to five years in the case of Herschel, and between year and half to two years and Planck.

Herschel mirror is equipped with the largest ever sent to space, 3.5 meters in diameter, which has complicated its placing in orbit, delayed several times.
