O’Rourke explained that the site in which “Fellay” landed was “the last puzzle to be solved” regarding the robot launched by the European space probe “Rosetta” on the surface of the comet “Churyumov-Gyrasymenko” or “Chori” in November 2014, about 500 km away. Million kilometers from planet Earth.
It was known that a technical defect made “Philae”, when touching the surface of the comet for the first time, to jump to another location for two hours, before finally settling at a distance of 30 meters.
The final location was not determined until about two years later, when one of the “Rosetta” cameras, who was still in orbit, detected the presence of “Velay” in it and was hidden in the shade, with no sunlight necessary to continue its activity, which made it enter an eternal slumber.
Pictures attached to the study, published in Nature, showed that the surface of the Chori was “very soft,” as O’Rourke described, “more soft than cappuccino foam, waves, or bubble baths.”
The results of the study contribute to enhancing the knowledge of this comet, which was formed 4.5 billion years ago, and to form a greater idea “of the stiffness of the surface of comets in preparation for sending other compounds.” Taylor, the European Agency took part in its statement.
