    Ooo baby! Now that is what I'm talkin' about! We get to see the whole sequence today too. It is awesome that we can see the actual wave tops! The landing legs look like a big set of fins when they are deployed which is why they were critical for preventing spin.

    Love how you can see the push back of the water in this shot as it slows down :)

    Well not as good as I'd hoped but you get enough to let you know it was successful. Telemetry said it reached zero velocity so it is a complete win for reusability. Leftover questions for me are how much fuel was left? How long did it maintain zero velocity? How high above the water did it achieve zero velocity?

    Damn. More waiting until the next attempt.

    Love them crowdsourcing it :D

    I was hoping the video would be better, but something is better than nothing. I'm looking forward to the next launch; hopefully conditions will be better.

    Damn... that's unfortunate... because it really does look almost completely worthless. What happened that messed the camera up so badly? was it the minor reentry that heated up the camera or something? I didn't think stage 1 went nearly that high into the sky to have that be an issue... Hopefully someone with some leet skillz can make something out of this.

    More like bad telemetry reception. The data was probably lost to noise. Spacecraft was probably too low for clear reception.

    Wow, nearly useless except for a few partial frames. Too bad, but it doesn't matters what counts is that we know the stage achieved and held zero velocity in a stable vertical position for long enough to demonstrate that a touchdown on land is the next step!

    The video is low quality, but still pretty cool.

    I'd really like a full length vid, though. I mean real time video from launch, to engine cut, to stage separation, ballistic flight, engine restart, leg deployment, hover, and splashdown all from the save POV.
    (Again similar to the videos NASA put out for the Shuttle SRBs.)

    You should email them and ask! Couldn't hurt right?

    Don't think there is a space rated GoPro yet!

    Video had to go via a telemetry link, where the video was secondary to the actual mission data. I image had they been able to recover the booster there would have been much better video of the splash down!

    Work on reconstructing the video is coming along pretty well:
    SpaceX Falcon9 First Stage (Booster) Landing - home

    I also read a pretty good explanation of what exactly they're doing to try to fix the video:
    SpaceX Falcon 9 v1.1 CRS-3 Splashdown Video Repair Task Thread

    I love the open source community <3

    They have made some pretty great progress on those 13 frames! The best SpaceX was able to provide previously was like 2 partial frames that looked somewhat discernible. I hope that SpaceX ends up doing something special for these people who contributed. :)

    I have unfortunately not had enough time to properly parse through all of the glorious information on the NSF forum, but I never realized that the legs deploy so soon before "impact" I would have thought they would be out long before the landing to increase aerodynamic drag.

    Cannot believe how much they've improved the video. Was reading some of the thread on NSF, simply mind-boggling.

    That was my thinking too, but now that I've seen them, I think deployed they'd add too much asymmetric drag at speed.

    Major props to the people who repaired the video! It's amazing to watch the landing legs deploy and the rockets fire as the Falcon 9 slowly approaches the water.
