Nasa’s Curiosity Mars rover starts drilling again

Curiosity Mars roverThe US space agency’s Curiosity Mars rover has drilled another hole on the Red Planet.

It is almost a year since the robot last turned the power tool in the ground.

The vehicle has since travelled more than 5km (three miles) as it heads towards the mission’s primary target – the foothills of the huge mountain that dominates Mars’ Gale crater.

The rock drill was spun at a scientific waypoint known as “The Kimberley”.

New pictures sent back to Earth on Wednesday, taken by the rover’s Mahli “hand lens”, show a sharply defined hole surrounded by a pile of grey powder.

Before turning the tool, the robot had been commanded to examine several rock targets with all its survey instruments.

Scientists and engineers must now assess the qualities of the powder produced. If past practice is followed, this will have been a test.
