CRS-5 Launch - YouTube
It is too bad that any video they capture of the first stage landing will be in the dark. I wonder how far out into the Atlantic the first stage lands. Maybe it will be sunrise in that part of the ocean at that time.
I wonder if they will tell us right away if the first stage landed successfully.
The rocket exhaust during landing should provide adequate illumination.
And I suspect that the landing barge will have floodlights shining on the landing area.
It's a couple hundred miles off Jacksonville, it's not far enough to be noticeably lighter that early I think. Someone transcribed the hazard area bulletin onto Google Maps: https://www.google.com/maps/d/viewer?mid=zp15b_P5ERVk.koWeOnV6-O-o
Your suspicions are correct;
Hope it all goes well!
In the morning everyone
Online broadcast is up - Countdown at T-15 min.
New here, when is the landing supposed to happen?
Hit the pad but crashed
Wonder if we'll see some pictures or video... Great launch though!
Damn. Watched the broadcast. That's great that it landed. Too bad about hard landing.
Elon Musk: "Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho."
How to achieve a less hard landing next time?
Some stunning visuals on the launch. Min 29 onwards on the video, separation, simply beautiful
They need to combine what they learned from Grasshopper/F9R with actual main stage. They obviously landed on the drone ship and into the eye of the needle. They just need to have a more precise burn in those last few seconds. I expect even hitting at 10 MPH is too much. But holy [email protected] they hit the landing pad but just a little too hard. That is a 99% success or more.
Way to go, SpaceX.
Successful launch and Dragon on orbit.
The grid fins worked at the first try, conserved enough fuel for explosion *
(In fact test was successful, accuracy changed: ~10 km to ~10 m)
Unlike Grasshopper and F9R-devxes, first stake can't hover so "hover slam" timing need to be precise.
* Elon Musk @elonmusk · Ship itself is fine. Some of the support equipment on the deck will need to be replaced...)
(Or maybe stake hit those and no kaboom.)
So the first stage landed on target, meaning within the larger circle I hope? That is impressive if true! Assume that it was still going too fast so there was significant damage to the stage and that it immediately fell over.
If that is the case then this launch represents real progress. Anxious to find out more details!
I'm curious about what Elon means by the hypersonic grid fins running out of hydraulic fluid? It is a closed system, is it not? How can it 'run out'?
Also, so, as speculated on here, it sounds like the issue was more related to the final burn than steering. Either way, it seems like the chance of success was significantly more 50%
Where you get power for a hydraulic pump? I guess, that the hydraulic pressure is provided by helium.
This point needs to be reiterated and shouted from the top of the tallest building. This was a success. The hard part is done. We're going to have reusable rockets really, really, really soon.
Amazing stuff. I think they will get it next time.
Will the onboard camera on the rocket be able to show anything? Or still too dark?
