NASA's Curiosity Rover on Mars Is Rolling (and Drilling) Again

After suffering a couple technical glitches that have put NASA's Curiosity rover off its duties on Mars this year, the robotic explorer seems to be back in full health, having driven to a new site and drilled a sampling hole, according to NASA statements. That hole is its 18th successful drilling assignment, according to NASA. It targeted a type of rock geologists with the mission have been eyeing for more than a month, but failed to successfully drill at a previous site. The drill was out of commission between late 2016 and this May as engineers addressed a problem with the instrument.
