Curiosity rover looks to horizon

The Curiosity Mars rover has lifted its mast and used its high navigation cameras for the first time.

The robot vehicle has returned black and white images that capture part of its own body, its shadow on the ground and views off to the horizon.

Spectacular relief - the rim cliffs of the crater in which the rover landed - can be seen in the distance.

Imaging scientist Justin Maki told our correspondent Jonathan Amos that Curiosity had a number of navigation cameras.
