Nasa reveals pictures of robot rover Curiosity on Mars

Nasa has used its high-resolution imaging satellite at the Red Planet to look down on the Curiosity rover and acquire a new picture of the recently landed six-wheeled robot.

The vehicle appears as a double dot.

The view from the Mars Reconnaissance Orbiter (MRO) has been colour-enhanced to emphasise certain ground features.

The BBC's Science correspondent, Pallab Ghosh, reports.
