For some reason I found it really cool that it was immediately gone into the overcast.
- detritus 10y ago
  I didn't! I was irritated that I couldn't see anything, so then had a quick scoot to see if the NASA feed would show the on-board view (unlikely!) before coming back again to miss the first stage separation! The landing through the clouds, on the other hand, I did appreciate. Once my irritation has subsided, anyway!

    I recommend watching the Hosted Webcast on one device and the Technical Webcast on another. Either mute the Technical Webcast or have it on lower volume. They're both easily found on YouTube under SpaceX. I did this for the previous launch, Iridium-1, and was treated to unbroken views live from the first stage on the technical stream, while the hosts narrated and switched views more frequently on their stream.
    - detritus 10y ago
      Oh, that's a good idea, thanks! Next launch! Yesterday I was stuck with just my phone though, so my 'alt-tabbing' was particularly tortuous :)
michaelhamel 10y ago
Successful landing!
CarolineW 10y ago
Nailed it!
XorNot 10y ago
The landing video for that was beautiful - great footage all the way down.
manibatra 10y ago
Amazing to live in times when the first stage landing back has started to feel like routine! Great job SpaceX!
lsaferite 10y ago
Awesome. Just watched it with my 7 year old son and he had so many questions. I love being able to pass on my love of space. :)
- imdsm 10y ago
  My son is 7... months old, so he doesn't really understand it yet. I can't wait until he's getting excited about these things.
smaddali 10y ago
It looked so routine, therefore so exciting.

Did anyone see the debris fly past before the second return burn of the first stage? Some ice I assume?
- jjallen 10y ago
  Yes! Wait are you talking about the second stage that was in the right/second monitor? I am. I thought it was weird that the two pieces stayed with the second stage for at least a second or two, which was literally ~five+ kilometers. Perhaps there was an eddy created by the movement of the rocket or some weird space/vacuum effect I'm not well-versed in?
  - wcoenen 10y ago
    The second stage debris that you are talking about showed up when the stage stopped accelerating. The debris and stage were moving at the same speed, so it's normal that they drifted apart relatively slowly.
- nprecup 10y ago
  Yes! I saw it at the 36 minute mark on the video. That had me curious. I think it was a trick of perspective, it first looked like some huge chunk of debris that the first stage flew past, but after watching it again, it looks like a little chunk of ice that got blown off of by the cold gas thrusters.
  - Luc 10y ago
    Yes, that's it, a few seconds after the 36 minutes mark. I think you're right, and it does look a lot smaller upon rewatching!
- lutorm 10y ago
  If you look back at old launch videos, you can often see big chunks of ice form by the second stage engine vents during coast, only to be blown off by the vibration as the engine is restarted. I assume this is something similar.
shripadk 10y ago
Bravo! Congrats SpaceX! :)
sidcool 10y ago
This is exhilarating! Perfect lift off, separation, landing and deployment. I am OK with this becoming routing and boring .
kegan 10y ago
How long does it take for Dragon to reach ISS? I should be able to see ISS tomorrow night from my location. Do you know if I would be able to see Dragon too?
- J0-nas 10y ago
  In the webcast they said that if you can see is ISS you'll see it
  - lutorm 10y ago
    Rendezvous isn't scheduled until the 22nd, so there will likely still be quite a distance between the ISS and Dragon tomorrow. They will be in trail, while the Earth rotates, so depending on where the ISS passes relative to you there's a possibility the Earth might have rotated enough by the time Dragon comes around to not see it. It's definitely worth keeping a look out though.
FLUX-YOU 10y ago
Oh god, 30-60 FPS during the entire landing except for the 15s burn. Fucking brilliant, SpaceX.
pbreit 10y ago
I hadn't seen the landing from the rocket before. That was cool. Makes me wonder what else in corporate america warrants employee cheering?
- mikeash 10y ago
  This is only the second time they've had live video all the way down. Getting that much data back from the thing must be tough. They've been making steady improvements, though, and it's now paying off delightfully.
  - rst 10y ago
    Probably easier when it's coming down on land, and not offshore past the horizon.
    - Ajedi32 10y ago
      The last one was offshore, and had video all the way down: https://youtu.be/tTmbSur4fcs?t=26m4s https://youtu.be/tTmbSur4fcs?t=26m4s

Always cool being able to watch these and understand how my dad felt during the space race of the 1960s.

- wiremine 10y ago
  Watched it this morning... extremely cool. I missed why they landed on land instead of on a barge. Anybody know?
  - unspecified 10y ago
    The landing is all based on how much fuel is left after the primary mission is complete: some missions require more fuel to get to their destination orbits, others require less. This launch was an ISS resupply, which is on the low end of fuel requirements. So the first stage can get all the way back to its launch site. Other launches are in the middle of the fuel range: they just follow their ballistic path to the barge, and do not have the extra fuel to get turned all the way back around for a return to the launch site. A few launches are at the very high end: the upcoming Echostar mission has such a high fuel requirement that SpaceX isn't even attempting a landing: they're just dumping the whole stage into the ocean like we've been doing for 60 years. SpaceX is saying that this upcoming Echostar launch will be their last "expendable launch", ever.

      Very helpful. Thx! > A few launches are at the very high end: the upcoming Echostar mission has such a high fuel requirement that SpaceX isn't even attempting a landing: they're just dumping the whole stage into the ocean like we've been doing for 60 years... SpaceX is saying that this upcoming Echostar launch will be their last "expendable launch", ever. Can I infer that they won't be doing launches that require high-end fuel usage? Are they just giving up on those types of use cases, or do they have another solution for those moving forward?

...and here's the technical webcast for those of you who can't stand talking heads: https://www.youtube.com/watch?v=rUDLxFUMC9c https://www.youtube.com/watch?v=rUDLxFUMC9c (Although they don't show the onboard footage for the takeoff, unfortunately. Or in-tank footage, which is always cool.)
