Curiosity flexed her mighty robotic arm for the first time on Monday (Aug. 20) and aimed the hand-like tool turret squarely at Mount Sharp, her ultimate driving destination.

If you want to see exactly where Curiosity is headed and why she was sent to Gale Crater, just take a look at the new mosaic assembled by Ken Kremer and Marco Di Lorenzo.

Curiosity is pointing with her robotic arm right at Mount Sharp, the huge 18,000 foot tall (5.5 kilometer) mysterious mound that covers the center of the 96 mile (154 km) wide crater. Our mosaic was prominently featured on the front page of NBC News and in a new article by Alan Boyle – here

The layered sediments in Mount Sharp could unveil the geologic history of Mars stretching back billions of years and reveal why the planet transitioned from an ancient, wet period of flowing liquid water on the surface to the dry, desiccated era of today.

As Curiosity unstowed and raised the 7 foot long (2.1 m) arm and reached towards Mount Sharp, the mast mounted navigation cameras on her head snapped a series of black and white images that included the shadow of NASA’s newest Martian robot. The 6 wheeled, car-sized rover made a harrowing pinpoint touchdown barely 2 weeks ago.

The arm is critical to the success of the mission because it will be used to maneuver a sophisticated turret, mounted at the arms terminus and laden with scientific instruments. It weighs a hefty 66 pounds (30 kg) and is about 2 feet in diameter. The turret includes a high resolution focusable color camera, a drill, an X-Ray spectrometer, a scoop and mechanisms for sieving and portioning samples of powdered rock and soil.

“We continue to hit home runs. We unstowed the robotic arm and took a look at the tools on the end of the arm,” said Curiosity Mission Manager Michael Watkins of NASA’s Jet Propulsion Lab (JPL) at a news briefing on Tuesday, Aug. 21. “It’s kind of a Swiss army knife there where we have a lot of instruments. We wanted to make sure all of that was working by doing these first motor checks. All of that went successfully.”

Watkins said the team was thrilled to finally see images of the arm deployed on Mars after seeing thousands of engineering test images.

“We have looked at images thousands of times in our test environment and I always see the walls of the test lab there.Now to see the arm out there deployed with Mars out there in the background is just a great feeling.”

The next step is more tests to confirm the arms utility and movements and calibrate the instruments . “We will fully check out the arm, drill and processing unit,” said Louise Jandura of JPL, sample system chief engineer for Curiosity, at the briefing. “The arm has already performed all these motions on Earth, but in a different gravity condition and that gravity does matter. Our turret at the end of the arm weighs as much as a small child and the differences in gravity change the amount of sag at the end of the arm. We want to be able to fine tune these end-point positions. So it will take some time to put the arm through all its paces.”

What’s more is that Curiosity is wiggling her wheels and is all set to make her first martian test drive on Wednesday.

“Late tonight, we plan to send Curiosity the commands for doing our first drive tomorrow,” said Watkins. “Curiosity will drive about 10 feet, turn right and then back up so her rear wheels will wind up about where her front wheels are now. The cameras will photograph the tracks and evaluate the performance of Curiosity driving ability and the softness of the surface soil.”

The 1 ton mega robot is also equipped with the DAN (Dynamic Albedo of Neutrons) instrument provided by Russia to check for water bound into minerals as hydrates in the top three feet (one meter) of soil beneath the rover.

“Curiosity has begun shooting neutrons into the ground,” said Igor Mitrofanov of Space Research Institute, Moscow, principal investigator for DAN. “We measure the amount of hydrogen in the soil by observing how the neutrons are scattered, and hydrogen on Mars is an indicator of water.”

The mission goal is to ascertain whether the Red Planet was ever capable of supporting microbial life, past or present and to search for the signs of life in the form of organic molecules during the 2 year primary mission phase.

    Editors,

    Are you of the opinion that your less educated readers will be frightened, or otherwise alienated, if you refer to Aeolis Mons by its correct name?

    If so, you are doing them a great disservice by not insisting on the use of proper nomenclature in popular science writing.

    By the way, where is that article about the Great Nebula in Andromeda?

    • Dampe August 22, 2012, 3:14 PM

      I don’t see the problem. Lots of places on Earth aren’t referred to by its correct historic/cultural/scientific name.

      • Shootist August 22, 2012, 5:00 PM

        such as what? The Pillars of Hercules? Qod? Gitche gumee?

        An international scientific union gives place names to planetary topographic, and albedo features. Why? To avoid the type of confusion found when places end up with more than one name.

        Olympus Mons isn’t called Mount Big-as-Texast!, for a reason.

        Sharp has a feature named for him. It is 250km away from Aeolis Mons.

          And this team sent a rover to mars. They can call it whatever the fuck they want. When you get your rover on mars, you can too.

          http://mars.jpl.nasa.gov/msl/multimedia/images/?ImageID=4494

          Your pedantry is annoying.

          I am not frightened, alienated or otherwise by the term “Aeolis Mons”. I am frightened by your pedantry. And I am educated about both terms.

          Are you afraid that readers can’t make up their own mind about what to call it? The Curiosity team could call it Mt DooDooBerry for all I care. They accomplished something many of us never will. They should be celebrated for what they are doing, not criticized for what they are calling the geologic feature they are about to explore.

          Its an informal name. Whats the harm? What are you afraid of?

          • Aqua4U August 22, 2012, 8:44 PM

            Come on Jeremy.. Please refrain from using base vernacular. Your comment(s) will be much more appreciated that way! There ARE kids reading this blog yah know? Set an example!

          • Shootist August 22, 2012, 9:21 PM

            You use the language of a potty mouthed 4th grader and I give you the same level of credence.

          • Mean_deviatioN August 23, 2012, 12:43 AM

            It is difficult to make up your mind if only one side of the argument is (consistently) presented. Nowhere is Aeolis Mons mentioned in this article, so the reader is unaware that such an ‘option’ exists for them to “make up their own mind”.

            Your ‘pedantry’ = ‘accuracy’ to others.

          • Jeremy Lepel August 25, 2012, 2:57 AM

            So, this is the only article anywhere on Mount Sharp, anywhere, ever?

            No one could search “Mount Sharp” on this thing called Google and find out it isn’t ONLY called Mount Sharp? Are you for real?

            The second result on google is the ITU name. Get over yourself.

            You’re basically trying to tell me the people who come to this site aren’t smart enough, or curious enough, about Mount Sharp to look it up somewhere else. They can make up their mind from the vast wealth of information on the subject, on THIS site AS WELL as many others.
            Pedantry it is. You guys are the definition of it, and thats whats at the “4th grade level”. You 3 are like an echo chamber. No, literally, since you mention it every time its on an article. People CAN make up their minds. The only site on the internet isn’t Universe Today!

          • Mean_deviatioN August 25, 2012, 3:32 AM

            Fair enough. I accept your opinion without (undue) criticism.

            However, a few clarifications as to your reply.

            • Your first statement is unfair, as I did not claim that, “this is the only article anywhere on Mount Sharp, anywhere, ever”.

            • While Google may be widely used, not all people, myself included, use it as my preferred source for searching information. Interestingly, a search of the UT site currently brings up 120 results for Mount Sharp and 36 for Aeolis Mons.

            • A reasonable assumption re curious people, but some may be “time poor”, for example, and have UT as a primary source. How many other sources across the internet would duplicate the information of this article I wonder? (Perhaps you could undertake such research for us?)

            • “You guys” ? I am only 1.

            • Not quite sure why the “4th grade level” comment was directed at me as I haven’t used it anywhere.

            • “You 3″ is also a bit odd as, again, I am only 1.

            • A simple search of the UT site will show how outrageous your statement, “No, literally, since you mention it every time its on an article”. That would be more time and effort than I could be bothered with.

            • I agree that people can make up their minds, given sufficient information, and the desire to pursue that information. But they can also do the same based on little and/or incorrect, information.

            • You seem to use a keyboard with a randomly functioning apostrophe key which makes your entries a little difficult to comprehend at first reading, e.g., its and thats and whats…but I fear I could be accused of being pedantic once more.

            • I am, however, very pleased that the world is not composed of those like me, or those like you, but rather a mix, which, from my experience, spark each other to keep life entertaining.

            Kind regards to you…and happy fishing.

          • Mean_deviatioN August 25, 2012, 6:26 AM

            ITU?

    • Aqua4U August 22, 2012, 8:47 PM

      If you were to spend the time searching UT’s extensive database, you will find several articles about the Andromeda GALAXY.. once thought to be a ‘nebula’.

  • mark o grady August 22, 2012, 1:21 PM

    It looks like curiosity can’t wait to get going on its journey. Destination Aeolis Mons (Mount Sharp). :-)

  • Bobby Hudson August 23, 2012, 6:40 PM

    Looks majestic,challenging.
