Philae of the Rosetta mission: Discovering a comet without a magnetic field


Scientists who track and record the movements of Europe's first detector who landed on a comet, Philae's mission Rosetta announced today that the comet of the project has no magnetic field! philae Rosetta
The news is of course the comet, 67P / Churyumov-Gerasimenko, and can provide some basic information about the formation of celestial bodies such as comets and planets - in the early stages of their development.

Ο Philae is a laundry-sized device disconnected from the Rosetta motherboat and landed in the comet. Since then, he has been collecting data (since last November). Scientists, therefore, studying these data, found that the surface was not magnetized, as reported in a report by the European Space AgencyESA), first published by Science magazine and presented at the European Geosciences Union in Vienna.

Let's remind that the landing of the detector was not smooth, and it took four attempts (three bounces) to reach the current landing area. The complexity of the landing helped the team discover that the comet did not have a magnetized core.

But the understanding of this "detail" came later when the team was able to compare measurements from different points of contact along the comet's surface.

Matthew Taylor, scientist at ESA's Rosetta project, told Nature. "The fact that Comet Churyumov-Gerasimenko has no magnetic field could help us solve the puzzle of the creation of the planets and how it evolved from the first planetary disk."

Philae is currently in hibernation to maintain the battery, but can be rebooted from the end of May. This means that communication could be restored perhaps by the end of June.
