Above is a self portrait by Curiosity after drilling a 1.6centimeter in diameter and 6.4 centimenter deep hole on a patch of martian outcrop called John Klien.
This feat marks another milestone for Curiosity and in execution was one of the most complex for handlers on Earth.
While Curiosity executed the first rock drilling on Mars, this isn’t the first time this is done on bodies outside the Earth. The Apollo astronauts collected lunar samples for Earth using hand-held battery powered drills. The Soviets have also deployed spacecraft that drilled into the lunar surface to collect rocks and also used robotic drills on missions to Venus.
