The giant asteroid Vesta is revealing more of itself to the US space agency's (Nasa) Dawn mission.

The probe has beamed back further images since entering into orbit around the 530km-wide rock on 17 July.

Dawn took the latest batch as it was travelling from the day side to the night side of Vesta.

The different lighting conditions provide scientists with additional information about the varied features on the rock's pockmarked surface.

As Dawn circles its target, so the asteroid itself turn on its axis. The rock rotates once every five hours and 20 minutes.
