    Are ring conventions different there or is that picture flipped horizontally?

    right hand is the wedding ring hand here, if that answers your question

    It does. Interesting.

    Anyway, bit of a launch post-mortem for those interested, some stuff I didn't think to share earlier, what this means going forward, upcoming launches (with a particular focus on upcoming cool launches, of course!):

    So that was a very pretty launch on what looked like a beautiful Florida afternoon. The Falcon 9 v1.1 launch vehicle performed nominally, delivering it's Dragon spacecraft into orbit en route to a rendezvous with the International Space Station.

    A lot happens in the first few minutes of a launch, so I thought I'd provide a little timeline of a nominal launch (like this one!):

    T 0s : Liftoff!
    T + 70s: Maximum atmospheric pressure as the rocket powers through the atmosphere
    T + 78s: We are supersonic! Get rekt, sound waves!
    T + 2m45s: Main Engine Cutoff, Stage Separation, Second Stage Engine Ignition, spacecraft now travelling at about 1.8km/s all happen around this time
    T + 3m: Do a flip! (The 1st stage reorients itself, turning almost 180 degrees and pointing back the way it came - sorta)
    T + 4m45s: 1st stage begins the first of 3 burns, known as the "boostback" burn as it reduces it's horizontal velocity to near 0.
    T + 5m: Stage 2 + Spacecraft are 165km up, 205km downrange, and travelling at 2.5km/s!
    T + 5m20s: Boostback burn complete!
    T + 6m50s: 1st stage begins the second of 3 burns, the "reentry" burn, where it slows its descent speed through the atmosphere so it doesn't get too hot - it has no "heat shield" to speak of, beyond what the engines and their thrust plate are already designed to resist.
    T + 7m20s: Reentry burn completed, second stage and Dragon spacecraft still doing their thang, going in to space, no big deal.
    T + 8m: 1st stage begins burn 3 of 3, the "landing burn" otherwise known as the "suicide" burn, where it tries to time it perfectly so that it reaches the barge right as its velocity is reduced to 0m/s. This is the part that apparently didn't go perfectly today. We lose telemetry data with the stage soon after this burn begins, which is why visual confirmation is necessary for the rest of its flight (times are therefore inexact for the first stage after this point.)
    T + 9m30s: Expected landing time for stage 1. Second Stage Engine Cut Off!
    T + 10m10s: Second stage separation, Dragon spacecraft deployed, Primary mission success!

    From this point on, things start moving a lot slower. If you want a description of the general flightplan for the Dragon spacecraft, I am of course more than happy to provide one, but I won't have things like exact times or anything available :)

    Anyway, no super-cool robo-barge landing today, but that's okay. It's an ambitious effort, and they're still learning and experimenting, and this is part of the process, as much as it does suck to see. Rocket re-usability is a huge goal of all of the Commercial Spaceflight enterprises, though, so it will be very cool seeing them all try their hand at their version of reusable technology.

    Update from Mr Musk:



    So it looks like it's still coming in too hot sideways, still. Very cool early pictures, though!

    that uh, doesn't count as a good landing.

    The aircraft landed just fine but had "excess forward velocity" and plowed through the terminal

    Eh. Most airplanes don't have to have a (0,0,0) velocity vector to not explode, though.

    that time I lost my license I took the turn just fine but I had excess sideways velocity and plowed into a garden with mom's bmw

    but it was a good turn

    Eh, in some ways. It's still got a much better political climate than rural US.

    Sticking the landing does seem like an important thing when failing causes things to go boom.

    yeah but it's also like, everything but a picture perfect landing makes it go boom

    so there's going to be a lot of *booom* "wow that went great so much better than last time"

    i'm also curious as to what level of recycling they'll be able to get out of the first stage even if they recover it. the space shuttle was reusable in only the loosest sense of the word. it basically had to be stripped down and rebuilt. no two flights used the same engines (the engines were removed, refurbished, and retested, about 60 or so in the fleet I think). they weren't even planning on removing them originally but yep, that's what they had to do.

    SpaceX is very curious about this too, but they already know from practice that stuff from water landings isn't very reusable, so this is their next best effort!

    Reusability is definitely a very uncertain business, but it's something to strive towards if only because it could make things so much cheaper.

    Those dang engines are expensive (which, as an aside, is why stage 2 recovery is less of a priority - it's much smaller and only has one engine anyway!)
