NASA's Mars rover Curiosity has pounded into a Red Planet rock with its drill for the first time, bringing the 1-ton robot a big step closer to initiating its first full-bore drilling operations.

The Curiosity rover hammered the rock using the arm-mounted drill's percussive action over the weekend, completing another test along the path toward spinning the bit and biting into rock for the first time.

"We tapped this rock on Mars with our drill. Keep it classy everyone," Curiosity flight director Bobak Ferdowsi — who gained fame as "Mohawk Guy" during the rover's nail-biting landing on the night of Aug. 5, 2012 — wrote in a Twitter post Sunday, sharing a photo of the pounded rock.

Curiosity's drill can bore 1 inch (2.5 centimeters) into Martian rock, deeper than any rover has been able to go before. Using the drill and its associated systems is a complex operation, so the mission team has been building up slowly to the first drilling activity on the Red Planet.

Last week, Curiosity performed some "pre-load" tests, pressing down on a rock with its drill in several different places to see if the amount of force applied matches predictions.

The six-wheeled robot has also been carefully evaluating its target rock, which is part of an outcrop the mission team has named "John Klein," after a former Curiosity deputy project manager who died in 2011.

Curiosity's main goal is to determine if its Gale Crater landing site could ever have supported microbial life. Along with the rover's 10 science instruments and 17 cameras, the drill is viewed as key in this quest, as it allows Curiosity to dig deep into Martian rocks for potential signs of past habitability.

The mission team wants to test the drill out on a target with scientific value, and John Klein seems to qualify. The outcrop shows many signs of past exposure to liquid water, including light-colored mineral veins that were apparently deposited by flowing water long ago.

    One of the first views from NASA's Curiosity rover, which landed on Mars on Aug. 5, shows the rover's shadow in the foreground and a 3-mile-high mountain known as Aeolis Mons or Mount Sharp in the distance. That mountain is the rover's eventual destination. The picture was taken through a "fisheye" wide-angle lens by one of the rover's hazard avoidance cameras.

    The four main pieces of hardware that arrived on Mars with NASA's Curiosity rover are pinpointed in this image from NASA's Mars Reconnaissance Orbiter, taken 24 hours after landing. The heat shield was the first piece to hit the ground, followed by the back shell attached to the parachute. The rover itself was lowered to the ground on cables by its rocket-powered sky crane. The cables were cut, and then the sky crane flew away to its own crash landing. (NASA / JPL-Caltech via Getty Images) Back to slideshow navigation

  18. Future mapped out

    NASA's Curiosity rover landed inside Gale Crater at the green dot, within the Yellowknife quadrangle, on Aug. 5. The team has decided to send it first to the region marked by a blue dot, that is nicknamed Glenelg. That area marks the intersection of three kinds of terrain. Then the rover will aim for the blue spot marked "Base of Mt. Sharp," where a natural break in Martian sand dunes will provide an opening for Curiosity to begin scaling the lower reaches of Mount Sharp.

  20. Mount Sharp

    Mount Sharp is seen in the distance in an image taken Aug. 23 by the 34-millimeter Mast Camera on Curiosity. The gravelly area around Curiosity's landing site is visible in the foreground. Farther away, about a third of the way up from the bottom of the image, the terrain falls off into a depression (a swale). Beyond the swale, in the middle of the image, is the boulder-strewn, red-brown rim of a moderately-sized impact crater. Father off in the distance, there are dark dunes and then the layered rock at the base of Mount Sharp. Some haze obscures the view, but the top ridge, depicted in this image, is 10 miles (16.2 kilometers) away. Scientists enhanced the color to show the Martian scene under the lighting conditions we have on Earth. (NASA via AFP - Getty Images) Back to slideshow navigation

    Small spherical objects fill the field in this Martian mosaic combining four images from the Microscopic Imager on NASA's Opportunity rover. The Sept. 6 view covers an area about 2.4 inches (6 centimeters) across, at an outcrop called Kirkwood in the Cape York segment of the western rim of Mars' Endeavour Crater. Shortly after its landing in 2004, Opportunity spotted similar spherules that were nicknamed "blueberries," but these berries are not as rich in iron, posing a scientific puzzle.

The four circular features on the front edge of the rover are the lenses for the left and right sets of Curiosity's hazard avoidance cameras, or Hazcams. Because of the different perspectives used for different images, some of the borders of the photos don't line up precisely. (NASA via AFP - Getty Images) Back to slideshow navigation
  24. A Martian rock called Jake

    NASA's Curiosity rover stopped about 8 feet (2.5 meters) in front of this Red Planet rock on Sept. 19, the mission's 43rd Martian day, or sol. The pyramid-shaped chunk was the first rock that the Curiosity rover touched for science's sake. It was named "Jake Matijevic" in honor of a top engineer who worked on every one of NASA's rover missions — but passed away just days after Curiosity's landing. Jake the rock, which measures about 10 inches (25 centimeters) tall, provided a good reference point for the rover's sophisticated instruments. (NASA via Getty Images) Back to slideshow navigation
  25. Rover's footprint

    NASA's Curiosity rover cut a wheel scuff mark into a wind-formed ripple at the "Rocknest" site on Mars to give researchers a better opportunity to examine the particle-size distribution of the material forming the ripple. The rover's right navigation camera took this image of the scuff mark on the mission's 57th Martian day, or sol (Oct. 3), the same sol that a wheel created the mark. For scale, the width of the wheel track is about 16 inches (40 centimeters). (Handout / Reuters) Back to slideshow navigation

  27. Life on Mars?

    The first sample of powdered rock extracted by the drill of Curiosity is seen on Feb. 20, 2013. Powder drilled out of a rock on Mars contains the best evidence yet that the Red Planet could have supported living microbes billions of years ago, the team behind NASA's Curiosity rover said March 12, 2013.

  28. The big picture

    This picture isn't from the Curiosity rover - it's a 2003 image from the Hubble Space Telescope, showing the full disk of Mars. The big picture hints at how much we'll be learning about the Red Planet during Curiosity's two-year, $2.5 billion mission. And that's just the beginning: Scientists hope the nuclear-powered rover will last years or even decades longer. (NASA via AP) Back to slideshow navigation
