The European Space Agency (ESA) announced the place comet 67P / Churyumov-Gerasimenko which is expected to Rosetta pose in November to carry out its scientific mission.
The name ‘ Zone J ‘, mission experts have chosen a place at one end of the kite is not completely flat and is not without risk to perform the approach and landing maneuvers but has proven to be the best among the five possible locations announced in late August.
“For we know that all J instruments can operate at full capacity ,” said astrophysicist at the University Paris-Sud 11, Jean-Pierre Bibring, who highlighted the “revolution” that will get direct data composition and properties of a comet , necessary to know the origins of the Earth and the Solar System.
approach and landing maneuvers
The Rosetta probe has been traveling through space for ten years in order to go approaching its target comet 67P. To reduce energy consumption in your journey, it was in hibernation two and half years, to ‘wake up’ in January this year.
Some seven months after the successful ‘awakening’ Rosetta reached orbit its desired comet and was located about 100 km from it. Today it is 30 miles from the target, but is expected to this week ten kilometers further in October ten approaches.
“We have validate what we have found and tested “maneuvers, said the director of the ESA Space Operations, Andrea Accomazzo, who explained that they are studying the course through Rosetta comet fall and landing maneuvers.
In November , is scheduled to Philae , who was carrying a probe Rosetta, engages the comet in the ‘Zona J’ with the aim of Rosetta performs its scientific mission.
Mission Critical Moment
Accomazzo stressed that the last few hours will be crucial for the number of decisions that will be taken and this will be the “critical operation” they have made in the center of the ESA Operations “by far “.
The ESA experts have revealed that there is a second option, a ‘Zone C’ it could be the alternative to the initial site chosen for landing Rosetta, but “has difficulties from the point of view of the dynamics”, commented the director of the landing of the probe, Stephan Ulamec.
When you arrive at 67P Rosetta will study the structure and composition of the comet nucleus -formed by ice and dust – to confirm if they are the same characteristics of the blocks that the planets formed 4,000 million years ago and therefore the origin of the Solar System
