Curiosity Snaps 'Arm's Length' Self Portrait

Posted by timothy on from the pleased-to-meet-me dept.

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.

      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.

      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.

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

      You can see shadows from the turret on the end of the arm in a couple of the raw images. 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 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! ;-)

      there's a lot of exposed wiring and cabling. is that really the best way to do this? I would have thought that it would be safer to at least enclose in tubing or put the wiring inside hollowed out areas of the arm.

      scrap that against a rock or have some rocks tumble on you and you lose wires.

      am I missing some great wisdom here? or are those exposed wires a liability waiting to happen?

      I'd imagine you have several possible problems:

      1. The protective casing breaks off. No different from laptops - what are the first parts to break? The small fiddly plastic bits like hinge covers, plastic connectors.

      2. If an electrical circuit breaks or has a short circuit, how do you know where exactly if it is concealed by tubes and covers?

      3. The extra casing would add more weight to the robot.

      Normally, things like satellites get covered in layers of insulation, gold foil and shielding, but that is due to radiation and extreme temperature change.

      It's not like they're scraping the sides of Hell's Canyon in this thing. Nobody is careening into rock walls. I'm sure this was debated at length in engineering meetings. If you cover everything, then you can't see it (duh). Visual inspection is one of the strong points of the Rover so by making everything all aerodynamic you potentially cover a lot of useful information.

      Besides, it looks cool this way. Very geeky.

    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.

    Now that I look at it more I can find even further flaws in your theory that that are not footprints. If you zoom in, magnify and apply 24 Laplace transforms (not enough room here to write them out completely), rotate 5 degrees, shift each pixel using a polar function, rotate -5 degrees, zoom, sharpen, smooth, stretch horizontally 314 pixels, rotate 1.618 degrees, add the height Mt Everest and subtract 15 before finally passing it through a modified Bresenham circle algorithm you can clearly see the thread. The threads are clearly from a shoe... not your so called "little trenches".

    I've done some more careful analysis and this is truly incredible. If you add the height of each Giza pyramid, convert the image to greyscale with each pixel having a value of 0-0xffff, add those values to the original image, mask with 0xffff, rotate by the circumference of the Great Pyramid, project the 2d greyscale image to 3D with an eye distance of -1 you get this. No joke.
