TheEpicSquared Posted January 14, 2017 Share Posted January 14, 2017 (edited) Successful deployment of all 10 satellites! Mission success! What a great return to flight! And what a great way to gather rep points! Edited January 14, 2017 by TheEpicSquared Link to comment Share on other sites More sharing options...
Oliverm001x Posted January 14, 2017 Share Posted January 14, 2017 Thank you for everything Spacex Can not wait until next time January the 26th 05:00-07:30 GMT. Until then, goodbye! Link to comment Share on other sites More sharing options...
CatastrophicFailure Posted January 14, 2017 Share Posted January 14, 2017 And now to clear out the hundred or so emails I get from the forum every time there's a launch. Not complaining. Link to comment Share on other sites More sharing options...

Nah, SpaceX is still behind Robin of Sherwood. I'll look forward to them splitting an F9 with another F9 at the upcoming FH test though. Improbable feats of marksmanship aside, congrats on absolutely successful return to flight SpaceX! Link to comment Share on other sites More sharing options...
Ultimate Steve Posted January 14, 2017 Share Posted January 14, 2017 I was sadly unable to watch the launch live, so I plugged my ears until I got home and watched it as if it was live. That landing - that camera view! A link to the rocket all the way down! YEAH! WOOOOOOOOOOOOOOOHOOOOOOOOOOOOOOOOOOOO! That is the highlight of this year so far for me. THAT WAS AWESOME!

Shpaget Posted January 14, 2017 Share Posted January 14, 2017 What's the deal with the instantaneous launch window? Those ten sats are bunched up after separation and each has to adjust its own orbit anyway. Is it due to plane change caused by Earth's rotation? But, even in the worst case scenario - polar orbit (which happens to be the case with Iridium NEXT) the change in plane is only 0,25° per minute, surely they can manage such plane change.

Has to do with lining the launch trajectory up with the barge. Link to comment Share on other sites More sharing options...

Also worth noting, IIRC all ten of those sats are going into the same plane, so mucking about with changing the plane of all ten after launch is probably impractical, hence the window.

Mad Rocket Scientist Posted January 14, 2017 Share Posted January 14, 2017 WOOOO!!!! Seeing a launch in person is amazing! It looked great, I was able to track it all the way to S1 seperation and see some of the nitrogen plumes with binoculars. Link to comment Share on other sites More sharing options...
Elthy Posted January 14, 2017 Share Posted January 14, 2017 I totaly forgot the launch until i looked at reddit. Watching a launch while knowing it wont explode is only half as exciting, just like sports when you know the outcome. But that stage 1 camera was awesome, i wished it was fullscreen.

Brotoro Posted January 15, 2017 Share Posted January 15, 2017 (edited) I would like it to remain half-screen, but with the simultaneous barge-cam view on the other half. Edited January 15, 2017 by Brotoro Link to comment Share on other sites More sharing options...
sojourner Posted January 15, 2017 Share Posted January 15, 2017 5 hours ago, Frybert said: Has to do with lining the launch trajectory up with the barge. Incorrect. They wouldn't limit the success of a paying customer's launch based on an attempted landing. Also, if that were true, then ALL of their launches with attempted barge landings would require instantaneous launch windows, which we know is not the case.

Shpaget Posted January 15, 2017 Share Posted January 15, 2017 The barge doesn't move a lot relative to the launch site. And is powered and maneouverable and the booster has guidance. The explanation is not satisfactory. Link to comment Share on other sites More sharing options...
Green Baron Posted January 15, 2017 Share Posted January 15, 2017 (edited) Good to see the SpaceX flying again ! They pointed out that the barge landing is "just" an experimental part of the mission, which first and foremost is to put the payload into orbit. Is it about the word "instantaneous" ? Maybe the instantaneous launch window was just was the name suggest, the possibility to launch into desired orbit at a certain time under certain conditions ... Just a guess.

I thought all the Iridium NEXT satellites were targeting a particular longitude? In which case it would be an instantaneous window, or as narrow a one as can be managed.The launch vehicle can compensate to some extent during ascent but it (obviously) only has a finite amount of fuel to waste. Assuming a circular orbit and taking the orbital velocity from the SpaceX feed, I make it a 33m/s delta-v for a 0,25° plane change. For comparison, the Shuttle OMS could put out about 300m/s total delta-V, so on that scale, 33m/s is not trivial. It also requires fuel that could otherwise be used for stationkeeping over the lifetime of the satellite. Link to comment Share on other sites More sharing options...

However an instant launch window would probably imply that if its any hold during the final part of countdown they abort and wait for the next window. The shuttle- mir missions had an less than 2 minute window who would be much of the same. Link to comment Share on other sites More sharing options...
