The Curiosity rover became the first-ever robot probe to drill into Martian rock as it collected a sample that may reveal further clues about a wet environment in the planet’s past.
The hole, which measures 0.63 inches (1.6 centimeters) wide and 2.5 inches deep, was visible in images and other data sent back to Earth today by Curiosity, NASA said in a statement. The rover will use lab instruments to analyze rock powder collected by the drill, NASA said.
