CURIOSITY MARS ROVER DRILLS AGAIN

For the first time since May 2013, the Curiosity rover on the surface of Mars has drilled into a rock. Images show a sharply defined hole surrounded by a pile of fine grey powder.

Curiosity has travelled more than three miles in the past year towards the primary target, the foothills of the huge central mountain in Gale crater. 

If this test drill proves satisfactory, Curiosity will acquire a second drill sample to be tested in the on-board laboratories.

Curiosity landed on Mars in August 2012. Drill samples last year contained evidence of an ancient lake. Conditions would have supported micro-organism if they had been present.
