    Emily Lakdawalla has full versions of the MRO descent image:

    Is that all one image or a composite?

    Is that Gale Crater directly under Curiosity?

    It, like all HiRISE images, is a composite of 10 thin 2048 pixel wide noodles, side by side.

    It is a piece of Gale crater under the rover, probably including the landing site itself. We've imaged that part of Gale already with HiRISE, hence how they managed to find the heatshield.

    The HiRISE folks now think the heat shield is also in the image:

    I can match up the parachute image with the lower left-hand edge of this image:

    Definitely Gale Crater right where they expected to be.

    (Thanks to pgrindrod over at UMSF for first spotting this.)

    So, Curiosity stuck the landing. Give the Mission team a gold medal! :-)

    As have all Mars EDLs; Curiosity had the added advantage of being able to move toward a preferred location. So it is possible (but not likely), the boat was brought back from even further 'down wind'. In any case it will be fun to see the complete reconstruction.

    First time I've ever heard of a highly sophisticated instrument package referred to as a "boat".

    Well it's nuclear, and it is packed with sophiscated communication and surveilance gear. Kinda looked like a sub, too, before shedding the heat shield.

    I've frequently heard people on this board refer to highly sophisticated instrument packages as "birds," too.
    As above, so below

    And if large enough, some even tend to call them a "moose".

    Someone at UMSF enhanced one of the descent camera frames:

    http://www.unmannedspaceflight.com/i...=post&id=27367

    (Original post at http://www.unmannedspaceflight.com/i...dpost&p=187614, but doesn't provide much additional information.)

    Think if you drop a line from the heat shield almost to the bottom edge of the image, then go a little bit to the right, that's almost exactly where the landing site is. Compare the HiRISE image:

    http://hirise.lpl.arizona.edu/images..._annotated.jpg

    In both images there's a differently-colored depression to the northeast with a seed-shaped crater inside it. Curiosity is a little to the southwest of the crater.

    See my post over at UMSF for a better elaboration:

    What did the original image look like before enhancement? How was the enhancement done?

    Ah cool. That picture looked so good I was thinking there was some hokey pokey going on, but seeing the original I see what happened. Even the original is a stunning capture.

    UMSF denizen has made movie of hi-res MARDI images:

    Can't get it to work for me on this machine, though, unfortunately.

    Same here. It's some sort of Codex issue.

    Wow, some great stuff coming up when every image is down, and properly edited... This one looks a bit skippy, have a look at Emily Lakdawalla's animated GIF a few posts down, and the youtube link also thereabouts.

    As some folks there mention too, when downloaded, it plays just fine in VLC, a very popular free media player. At least, on my system it does.

    Someone's put together the high-resolution MARDI frames into a movie. I couldn't play it on the web but could download it and play it in Quicktime:

    The full duration, high-res MARDI video from heat shield seperation to after touchdown. Notice the scours being formed and the dust settling near the end of the video.

  25. #175
    Using the images raw, as they are, isn't ideal. They need to be reprojected and rotated to make the most of them. This is all the full res frames that were down as of yesterday - http://www.youtube.com/watch?v=v45vFbTg6KM

  26. #176
    Update - only a half dozen or so frames were missing from the 666 that take us from camera-on to touchdown

    http://youtu.be/H_7poFd6JCE?hd=1

    And no - I'm not joking....666

    The official MSL project animation was 11mins 6 seconds long

    See a pattern

    The Martians, who apparently have very effective cloaking devices, probably view Curiosity as a devilish creature, with 17 eyes and a laser tongue.... for starters.

    Edit to add: Hmm. That was my 6,666th post.

    Recap of the touchdown as seen by the insiders:

    First Words of Safe Landing on Mars - Tango Delta Nominal

    10:32 p.m. on the evening of Aug. 5 was turning out to be one long minute for Steve Sell. Of course, the previous six had been significantly protracted as well. When added together, the entry, descent and landing of NASA's Curiosity Mars rover had been touted as "Seven Minutes of Terror," and as far as Sell was concerned things were trending in that direction. What the 42-year-old engineer from Gettysburg, Pa., wanted more than anything in that seventh minute was to hear the words "UHF Strong."

    Some guy who goes by the moniker "Bad Astronomer" has posted links to two videos made from full-resolution images taken by the MARDI.

    Bloody hell!

    I notice there was still a lot of billowing going on.
