Mission scientist reacts to historic first images from the surface of a comet

Bright Comet 46P/Wirtanen skims past Earth just 30 lunar distances away on 16 December when it could become a diffuse magnitude +3 object almost a degree wide located between the Pleiades and Aldebaran in the constellation of Taurus. Grab your binoculars and find a dark sky location well away from streetlights to enjoy this Christmas comet before the glow from a waxing Moon gets too bright from 17 December.

Optimistic Europe’s hibernating Philae comet lander can be revived, mission controllers plan to try and contact the spacecraft as soon as January as the search narrows for the probe’s final resting place — a site within arm’s reach of pristine ice and organic matter ripe for analysis if the mission gets a new lease on life.

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.
