Mission Rosetta: success in separating and beginning the descent of Philae to the Comet 67P

The space robot module Philae separated successfully from the Rosetta probe and initiated the downward journey toward the surface of the Comet Churyumov-Gerasimenko/67P. After 10 years and seven months traveling coupled to the probe Rosetta, the Philae broke away and took over the Mission for which it was created around 8:45 this Wednesday (Lisbon time). Half an hour later, the Rosetta mission control center for the European Space Agency (ESA, the acronym in English), in Darmstadt, Germany, received the message of confirmation of the success of the operation issued by Rosetta.

The "delay" (delay) between the emission and reception in the land of the radio signal from the probe Rosetta due to the more than 500 million miles that separate it, right now, our planet. This distance is that the radio signals emitted take 28 minutes and 20 seconds to reach. The Philae, however, is also being monitored by a system called CONSERT, which will inform the respective control center, the altitude and speed of the descent, which stretches for just over 20 kilometers at a speed estimated at 3.5 miles per hour, which means about 7:0 to the landing at 67P, scheduled for around 4:0 pm in Portugal.

The "acometagem" will be ensured by a system of hooks in the landing gear that will "grab" the Philae to the comet's surface, preventing him from pointing out to the space after the first clash in the soil â€" it should be noted that the 100 pounds of weight of Philae are equivalent to a simple grass in low gravity of Comet 67P.

The Mission of Philea on the surface of the Comet Churyumov-Gerasimenko/67P aims to study the composition of Comet, realize his behavior on the route that keeps the Sun and the expetactiva is to find it, for example, water in the solid state. The estimated on the planet's surface temperature is 70 degrees celsius and this must have contributed to the Comet preserve in ´ frozen water some signs that will help us to deepen the knowledge about the formation of the solar system, the very origin of life on Earth and, who knows, the existence of living organisms beyond our planet.

Involved in the Rosetta Project, Matt Taylor coming "voyage to Comet, is to understand how comets work in General". "This is a fundamental objective of this mission. Follow the Comet, he passes the perihelion, next year, as it approaches the Sun and then returns. Let's look at the changes in the Comet and the changes in its activity, "explained Matt Taylor, scientist known to have tattooed on her thigh a image that integrates the Rosetta and Philae lander on the comet.
