This is the launch that will actually try to land on the ocean platform ! [1] Also, the boss is doing an AMA.

I don't see any video, just the twitter? feed when I view this. What am I doing wrong? I've had to fall back to NASATV edit: I bet that's what the 5 mins remaining on the countdown is waiting for. I'm really stupid. edit2: Stupidity confirmed, video is now live.

Musk from the AMA: There is a great quote by Churchill: "If you're going through hell, keep going."
AliCollins 12y ago
Last I heard they gave a 50/50 chance of landing the first stage...so quick poll: do you think they'll do it?!
- AliCollins 12y ago
  Yes!
- omegant 12y ago
  Yes!
- chadpaulson 12y ago
  Yep.
- pavelrub 12y ago
  From Musk's AMA on reddit: Q: Previously, you've stated that you estimate a 50% probability of success with the attempted landing on the automated spaceport drone ship tomorrow. Can you discuss the factors that were considered to make that estimation? A: I pretty much made that up. I have no idea :)
  - AliCollins 12y ago
    Fantastic! Give the man a fag packet to write on the back of and we'll see what he comes up with next!!
  - TeMPOraL 12y ago
    To be honest, 50% probability is the definition of "I have no idea" ;).
- chiph 12y ago
  They've shown they can land on a fixed pad with their rockets. I think the critical factor will be what the wave action will be like. If the barge comes up at the exact time one of the landing legs is coming down -- things could go badly.

Hold Hold Hold Abort :(
- jacquesm 12y ago
  Too bad... but a lot better than losing a rocket.
  - agildehaus 12y ago
    The one second launch window made any hold an abort :(
    - jacquesm 12y ago
      Why was the launch window that short? Matching trajectory with ISS?
      - lutorm 12y ago
        Yeah. Given that the ISS passes overhead at ~7km/s, a little delay in launch time would mean a lot of catching up to do.
  - anvandare 12y ago
    I agree. Unlike Kerbals, we are wary of potentially catastrophic outcomes. :) Ah well, next attempt on Friday!
- WestCoastJustin 12y ago
  Aborted due to issue with stage two. Next launch attempt might be Jan 9th at the earliest. Via webcast for anyone who missed it.
  - trothamel 12y ago
    The issue was apparently drift in the actuators that positioned the second stage engine.
conorsibley 12y ago
Did I really wake up early for that?
- jacquesm 12y ago
  Would you feel the same way if you didn't wake up and you missed it? This is not some two bit web app and there are plenty of people that can't manage to make those work. Instead of being irritated the lesson to learn here is that it is better to abort 10 times than to blow up in mid-air even once.
  - AliCollins 12y ago
    Also, if SpaceX rockets move to carrying people, having that perfect record is even more important.

That's weird, this post and it's comments appeared on the site hours ago, but seems to have re-appeared in an early form with the comment ages reset.

Was at Canaveral this AM... total bummer.
