After a two-year stint on the disabled list, Curiosity's drill is working again. This week, the Mars rover successfully collected a rock sample for the first time in almost two years.
Over the last year, engineers at NASA have developed a workaround drilling technique called Feed Extended Drilling, or FED, which uses the rover's robotic arm to direct and push the drill into the ground as the drill bit spins. And last week, Curiosity engineers added percussion, or a hammering rhythm, to the FED technique.
The fix worked. Over the weekend, Curiosity drilled two inches into the Martian surface and collected a powder sample from the pulverized rock.
That looks like dried plant stalks running under the pile of dirt. Yes No? I have never seen pictures of any plant life on Mars.
