OSIRIS narrow-angle camera

Philae found! Rosetta’s lander wedged in cometary crevice

5 September 2016 Astronomy Now

Less than a month before the end of the mission, Rosetta’s high-resolution camera has revealed the Philae lander wedged into a dark crack on Comet 67P/Churyumov–Gerasimenko. The images were taken on 2 September by the OSIRIS narrow-angle camera as the orbiter came within 2.7 kilometres of the comet’s surface.

Rosetta studies Comet 67P at perihelion

14 August 2015 Astronomy Now

ESA’s Rosetta spacecraft has witnessed 67P/Churyumov–Gerasimenko make its closest approach to the Sun (perihelion) at 3:03am BST on 13 August, when the comet came within 116 million miles of our nearest star. Rosetta’s measurements suggest the comet is currently spewing up to 300kg of water vapour and a metric tonne of dust every second, creating dangerous working conditions for the spacecraft.
