NASA rover drills on Mars after over 1 yr, makes 2-inch hole
NASA engineers controlling Curiosity rover on Mars have revealed it successfully drilled a 2-inch-deep hole on Mars surface on May 20, capturing the first rock sample since October 2016. The mini-laboratories inside the rover help scientists understand the Red Planet by conducting chemical and mineralogical analyses of rock and soil samples acquired from Gale Crater, where it landed in 2012.
