Rosetta comet mission: Close-up look at Philae lander
Europe's Rosetta probe has arrived at a comet after a 10-year chase.
In a first for space exploration, the satellite was manoeuvred alongside the speeding ice body to begin mapping its surface in detail.
Esa says that Rosetta's Philae lander will try to touch down on comet 67P/Churyumov-Gerasimenko on 11 November.
Science editor David Shukman takes a closer look at the small craft designed to complete the mission.
