The surface of Comet Chori is softer than a cappuccino foam!


PARIS – A study revealed Wednesday that the robot “Feli” bounced twice on the surface of comet “Chori” six years ago, before landing permanently, to find that this surface consists of a mixture of ice and dust “softer than a cappuccino foam.”

Study author Lawrence O’Rourke of the European Space Agency explained that the site where “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. / November 2014, about 500 million km from planet Earth.

It was known that a technical defect made “Fellay”, 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.
