Paolo Ferri, ESA’s Head of Mission Operations, expresses relief at the apparently successful release of Philae from the Rosetta mothership but the potential loss of a crucial touchdown system has caused increased anxiety about the landing.
Based on computer simulations, astrophysicists at the University of Bern conclude that comet 67P/Churyumov–Gerasimenko did not obtain its duck-like form during the formation of our solar system 4.5 billion years ago. Although it does contain primordial material, they are able to show that the comet in its present form is hardly more than a billion years old.
Europe’s Rosetta comet probe re-established momentary contact with the Philae lander late Thursday, renewing hopes of starting up the craft’s research instruments after two weeks of radio silence dampened the moods of scientists.
