Rosetta's comet: expect the unexpected
Paris (ESA) Jun 24, 2014
An image snapped earlier this month by ESA's Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects. The picture was captured on 4 June by Rosetta's scientific camera, and is the most recent full-resolution image from the narrow-angle sensor. It has been used to help fine-tune Rosetta's navigation towards comet 67P/Churyumov-Gerasimenko, which was 430 000 km away at the time. Strikingly, there is no longer any sign of the extended ... read more
