SpaceX Falcon 9 FT launch - Thaicom 8 - SLC-40

[Grendal]

Ok:

Elon Musk "Rocket landing speed was close to design max & used up contingency crush core, hence back & forth motion. Prob ok, but some risk of tipping."

e.g. One(Some )of the legs used it a crumpling zone?

More from Elon: "Crush core is aluminum honeycomb for energy absorption in the telescoping actuator. Easy to replace (if Falcon makes it back to port)."

I wonder if it happened from the landing itself? Or was it because of the extreme landing burn putting excessive pressure on the core? Maybe we'll find out more details.

Hope they have recordings from multiples angles and sources..

Or a nice video from a chase plane... I love the chase plane videos.

Landing itself. It is no doubt at the end of the actuator stroke. It's sort of like a bump stop in automobile suspension, except not reusable.

Crushable honeycomb cores are pretty typical for one time shock absorption in space vehicles. Its light and effective. And can have reasonably repeatable performance.

Okay. This is the coolest video yet:

Hat trick! Wow I live for these webcasts now. The shot as the first stage fired the reentry burn was amazing. The cameras were disposed of for entry but imagine the shot if they can keep one shooting all the way to the still love you! Can't wait until the first booster is reused, mars in their sights!

Did you miss my post just before yours?

All the way in... Only a brief moment where the camera gets clogged with schmutz.

Youtube has a settings section where you can slow down the video. I just watched it at the slowest setting. Highly recommended.

So is that about 2 minutes of real time compressed into 30 seconds?

That blew my mind. Again.

I looked in the YouTube settings and do not see a way to change the video playback speed.

Push 'play' in the embedded video in the thread then move your mouse to the lower right hand corner. Click the 'wheel' (settings), choose 'speed' etc...

 

[Daliman]

Grendal, thanks so much! My mind is officially blown. I was writing my post and didn't see yours until later. Coolest post of the day!

Okay, thanks, I did that but no "Speed" control appeared. I'm in Chrome in iOS and on my Mac. Maybe it's a Windows thing.

Could be. There is a little cog shaped symbol in the lower right. If you click on it, it gives you a few choices and one is speed. You can slow the playback to .25. If you don't get the cog shaped symbol then it's a windows thing.

Use HTML5 for playback instead of Flash and you will have speed control.

Here we go:

The Hosted Webcast:

For those that don't want to hear all the chatter, The Technical Webcast:

Thanks @Grendal for posting the webcast early on so I knew where to find it!

First time I've been able to see the 1st stage landing real time!

Wish I could give rep points again... changed my "like" to "love" instead!

Why does the side view look like the rocket is leaning quite a bit to one side? Optical illusion or bent leg?

Part of it is an optical illusion. Part of it might be what Elon tweeted about the aluminum honeycomb leg crush. The cameras are a type of fish eye go-pro lens which distorts the image. You were not the first to notice it though.

Or it's a hoax?

If you have 3 minutes listen to this guy spew gall:

 

[Electroman]

Idiot.

I can't be bothered to spend any time listening to completely delusional people.

 

[scaesare]

C'mon. He has some other very convincing videos proving the earth is actually flat.

Try and be a bit more open minded.

 

[Johan]

For every action there's a reaction. It's rocket sience and human culture all mixed up. Poetic.

 

[Grendal]

He has a whole series of videos. Cuckoo.
