Stage 1 separation. Here we go. EDIT: "Stage 1 boost back shutdown" EDIT 2: "Loss of signal from Stage 1" (expected)
- sargun 12y ago
  Where is it? Is there a feed of its location, or the landing pad?
  - garretruh 12y ago
    It's completed it's boost back burn, so it's on a trajectory towards the landing barge (positioned off shore a good distance). EDIT: All this is just from the radio transmissions broadcast on the SpaceX YouTube stream.
    - sargun 12y ago
      From the Reddit post: [T + 15:45] Jon - Mission success. We have data but not good enough to put on the live stream yet (poor connection). Updates here as they come! Sounds good?

I wasn't able to find much information about the details of the Stage 1 recovery. How long does it take for it to make it back? Will we know the outcome within a few minutes? (trying to decide if it makes sense to sleep) EDIT: Reddit seems to have comprehensive coverage http://www.reddit.com/r/spacex/comments/2rrdha/rspacex_crs5_official_launch_discussion_updates/ http://www.reddit.com/r/spacex/comments/2rrdha/rspacex_crs5_...

  It'll be a few minutes. They said they'll show video of the landing on the stream if it is successful so it's worth sticking around until the stream is done. Edit: hmmm, maybe that was wrong info, looks like they'll tell us about the landing on twitter. Probably time to head to bed I guess then.
- garretruh 12y ago
  SpaceX has said that they will announce the status of the first stage as soon as they know on the webcast. And if successful (and they have a good link to the barge), they'll also play a replay of the landing. EDIT: Or not. Looks like they wound down the SpaceX broadcast. NASA TV is still broadcasting the launch though.
- dabeeeenster 12y ago
  It won't take long to reach the surface but I don't think we'll get the news of whether it was successful or not for some time...

  From Reddit: [10:05 UTC/5:05 EST] Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho. Aww, better luck next time.

I wish they provided a bit more narration with this. Would love to know more about what I'm looking at and know what is going on with Stage 1 recovery.
- iliis 12y ago
  Indeed. Some live telemetry data to put on your second screen would also be cool. NASA TV showed essentialy the same footage with a few more comments (http://www.nasa.gov/multimedia/nasatv/index.html http://www.nasa.gov/multimedia/nasatv/index.html).

For a few minutes we could see bubbles of liquid (water?) floating around in zero gravity in some kind of container, the whole scene being lit with pink lighting. Any idea what this is?

  That's a camera from inside the fuel tank. The droplets started floating once you had engine cut-off, i.e.: it wasn't accelerating and therefore had no 'gravity' pushing the fuel to the bottom any more.

  Liquid oxygen! Beautiful blue color, even more so when floating around in microgravity. I love that they light up the interior purely for our benefit. It's Elon's art piece.

Anyone just see that piece of debris float away from the Dragon capsule? Is that normal? At about t+ 00:12:55 https://www.youtube.com/watch?v=p7x-SumbynI&t=1975 https://www.youtube.com/watch?v=p7x-SumbynI&t=1975

  I really want to see video of that! How hard? Explosion hard? Broken strut hard? Hole in the drone-ship hard? Sorry, my KSP avatar took over there... EDIT: I just used the term "drone-ship" legitimately in a sentence. We are living in the future.
  - jccooper 12y ago
    We know where the target ship docks. I'm sure there will be photos of its state soon. I for one can't wait.
- ErrantX 12y ago
  News outlets seem to be wrwriting this up as a crash, and therefore a failure. But my thought is; holy crap they actually hit the target? Pretty impressive!
  - ianetaylor 12y ago
    Exactly. SpaceX said this would be 50/50 at best so not a failure in that sense. They'll go again in a month with more hydraulic fluid and learn more. No doubt it'll take a whole series of tests to get this working reliably. Still impressive imho.
- jccooper 12y ago
  I'd think it was a good result if the stage came down within a few hundred yards of its target. But touching? Break out the champagne. They be able to dial it in for sure.

Dragon launch went flawlessly, looks like the first stage landing was close but not quite good enough: https://twitter.com/elonmusk/status/553855109114101760 https://twitter.com/elonmusk/status/553855109114101760 "Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho." In any event, a great, very smooth launch. And folks at NASA must be breathing a sigh of relief since this is the first US resupply mission since the Antares launch failure.

- FatalLogic 12y ago
  Don't military pilots say a carrier landing is much more difficult than landing on solid ground? Because the area is small, and not stable. It seems like SpaceX have had to start out by attempting the most difficult possible landing scenario (for good safety reasons). So they did OK, considering the difficulty.
  - izacus 12y ago
    Well, carriers have significantly shorter landing strips, require the pilot to either hit a cable or immediately take off again and usually move themselves to provide more favorable wind conditions to pilots. SpaceX drone platform is easier in that respect, since the rocket is landing vertically and alot of those factors are mitigated. It's still a extremely hard and complex problem to solve - it IS rocket science after all ;)
    - FatalLogic 12y ago
      It's an interesting comparison. At least, with a carrier you can go around, but I suppose that, for an aircraft landing on a carrier, the moment of irreversible commitment to landing maybe comes a second or two earlier than it does for SpaceX. I don't know if the SpaceX vehicle is programmed to back off and wait if a big wave rocks the platform, but it could do that, wind permitting (edit: no, it couldn't, apparently, see reply by Denvercoder9). Fuel is limited, but it seems like it should be able to hover for a few seconds and wait for the platform to stabilize if necessary. Anyway, they're not developing a sea-landing vehicle, so it's understandable if they don't spend so much time thinking about that. It's designed to land on solid ground, I think and the ground doesn't usually move, after all.

Bastards! I foolishly just assumed that it was going to launch at the same time as the earlier attempt last week (although 1 seconds thought would have made me realize that this was highly improbable...)

Too bad the landing didn't work out yet but at least this will - hopefully - squelch the haters that keep repeating the mantra that SpaceX is merely re-using what was already known and not innovating. I figure they'll need a couple of tries at least to get that right, we're witnessing an enormous step on the path to access to space. What's amazing is the increase in accuracy with this attempted landing, the whole grid-fin thing seems to work exactly as planned.
- bane 12y ago
  If they can nail this, and get it right...when the costs to space are driven down to what they're planning, it'll turn ultra-expensive efforts like the ISS into merely expensive efforts. Imagine if each country in the G-20 had a couple ISS-class stations up there plus a half dozen commercial ones as well!
