Lander manager provides update on Philae status

Views from Europe’s Rosetta comet orbiter show mysterious markings appearing on the nucleus of Comet 67P in recent months, with new surface features forming within a matter of weeks, and scientists are digging into the complex causes of the cometary erosion.

Astronomers were watching when comet P/2016 BA14 flew close by Earth on 22 March at a distance of slightly more than nine times the distance of the Moon. Radar images from the flyby indicate that the body is about a kilometre in diameter, while infrared spectra indicate that the comet’s nucleus is as dark as fresh asphalt.

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.
