Curiosity Snaps 'Arm's Length' Self Portrait 96

astroengine writes "Using its robotic arm-mounted MAHLI camera, NASA's Mars rover Curiosity has snapped, quite possibly, the most iconic image to come from the mission so far. By stitching together 55 high-resolution photos, the rover has snapped an 'arm's length' self portrait, capturing its location in the geologically interesting area known as 'Rocknest,' including its recent scoop marks in the Martian soil and the base of Mt. Sharp." Note to NASA: Please sell this image in the form of a fundraising poster.

      It's a series of images that, when stitched, conveniently exclude the arm.

        True, but where does the arm attach to the rover? That end of the arm must be visible on any picture taking of that part of the rover. I am curious to see the individual parts, just to figure out how that part of the rover really looks.

          Apparently it is attached to the rover by the horizontal cylinder shaped appendix between the front wheels.

          (Of note - the raw images got released quite a few hours before the official stitched version did. So a bunch of amateurs including myself [hylobatidae.org] and others [unmannedspaceflight.com] used various panorama-assembling software to assemble our own, unofficial stitched versions. Seeing Curiosity like this before pretty much everyone else was great...)

          Take a look at the high res photo:
          http://photojournal.jpl.nasa.gov/jpeg/PIA16239.jpg [nasa.gov]

          In front of the corner of Curiosity closest to the camera, there's a dark grey cylinder with part faded out. Beneath, and slightly lateral to this you can see a motor which has had the top left corner diagonally cut out of it.

          The arm was attached to this area, and that why as it rotated the picture here changed. It's the only place there are any major artefacts in the image.

        It seems to be excluding any shadow of any arm as well, The shadows for everything are plainly visible almost a straight down angle as if the sun is almost directly overhead... There's not even a shadow for an arm.

          Look again. Follow that structure straight down the middle of the image to the bottom visible wheel, see how it casts a shadow? Now follow up towards the 10 O'clock position and suddenly there's a bit of that structure with a shadow and yet nothing above it? That's the support for the camera.

          You can see shadows from the turret on the end of the arm in a couple of the raw images [nasa.gov]. Whoever planned the arm manoeuvres did an incredible job - not only did the arm itself almost completely disappear in final stitched versions, the images have very little parallax despite the arm very much not being a proper panoramic camera mount.

          Of note - there was a second [nasa.gov] set of images taken - very similar to the first, but with a small horizontal offset. Likely result? 3D versions of the panorama!

          The only thing I want now is, perhaps in a year or so, a full 360-degrees spherical panorama of the rover parked near some interesting cliffs or other geography. Go on, NASA - do it! ;-)

        Good one for public relations, NASA.

        Reminds me of that scene from M*A*S*H where Father Mulcahey grows corn all year and, after harvesting, the army cook turns it into creamed corn.

      Check out the image to conventional portrait [wikimedia.org] of Curiosity in the Wikipedia entry [wikipedia.org]. You'll see there is a robotic arm mounted on the front of the rover that does not appear in the self portrait.

      If you think of the robotic arm as analogous to a human arm, it has a pair of motors at the "shoulder" (for two axes of motion), one at the "elbow" and another pair at the "wrist". In the self portrait only the "shoulder" of the arm is visible -- you can see one of the motors (which looks like a pair of stacked black

    To the Mars natives, Curiosity is known as the "Rocknest Monster"

    • at least 2 large green men were heard uttering "this was not born here. can you find its manufacturing certificate, anywhere? there's only the short panel of text on the side, we need to see the longer version."

      yes, 'doubters' on mars are really big and heavy.

      that's why we call them girthers.

      NASA figured out that the surest way to meet some easy Martians is to post an arm's-length photo of yourself on mars.craigslist.com/personals/casualencounters

    Original Caption Released with Image:

            On Sol 84 (Oct. 31, 2012), NASA's Curiosity rover used the Mars Hand Lens Imager (MAHLI) to capture this set of 55 high-resolution images, which were stitched together to create this full-color self-portrait.

            The mosaic shows the rover at "Rocknest," the spot in Gale Crater where the mission's first scoop sampling took place. Four scoop scars can be seen in the regolith in front of the rover.

            The base of Gale Crater's 3-mile-high (5-kilometer) sedimentary mountain, Mount Sharp, rises on the right side of the frame. Mountains in the background to the left are the northern wall of Gale Crater. The Martian landscape appears inverted within the round, reflective ChemCam instrument at the top of the rover's mast.

            Self-portraits like this one document the state of the rover and allow mission engineers to track changes over time, such as dust accumulation and wheel wear. Due to its location on the end of the robotic arm, only MAHLI (among the rover's 17 cameras) is able to image some parts of the craft, including the port-side wheels.

            This high-resolution mosaic is a more detailed version of the low-resolution version created with thumbnail images, at PIA16238.

            JPL manages the Mars Science Laboratory/Curiosity for NASA's Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL, a division of the California Institute of Technology in Pasadena.

          I agree that it's better to link a primary source rather than some watered-down news site or blog. But I don't see them selling links here, just not bothering to track down the original source. Slashdot editors barely even read the submissions they post, never mind editing them for commercial purposes.
