It looks great, but why insist on uploading such a large thing as a GIF? (or GIF equivalent) If it is a movie (series of images), there is no shame in making a movie file...  :) (i.e. MP4 or something like it)

Thank you, I just prefer a file that loops (which honestly I don't know if I can do that with a video). Might end up putting an .MP4 as well when I get a chance!

This is a neat view... maybe the closest one of the booster landings - taken from the Delta IV launch tower:

(Although the guy recording missed the landing moment in his excitement)  ;)



The Uber shaky cell-phone vid only makes it more surreal.

I now have a different mental image of what an alien invasion (or just a future marine assault) will look like.

Forget the Sci-Fi imagery of large ships slowly descending...

Instead, hundreds or thousands of cylinders coming down at terminal velocity (or even faster!), then a last second retro burn, ramps opening, soldiers running out...

Coming soon to a theater near you.

Sactly what I had in mind...

The legs opening in the last second is pretty alien too.

Apologies if repost. GREAT audio and angle of the booster(s) landing.



Is this the first time that we have seen landing video from LC-37B (Delta-IV pad)?  I don't remember seeing landing video this close in for previous landings that wasn't official SpaceX cameras. 

I would assume that ULA would have had to allow access to it's pad infrastructure to record this event, is that correct?  Or was this ULA employees recording the landing?

The same person (YouTube Handle: ChillyWilly) has taken other landings from the same location:

So far, German media was very positive and enthusiastic about Falcon Heavy and its launch. I have seen several very well written and factually correct (!!) articles. But a few days ago, some articles came up that quote William Anders (Apollo 8) who voices all sorts of criticism about SpaceX. Unfortunately, this seemed to be the result of an interview Anders gave to a German newspaper. So there is no primary English source. I am paraphrasing:

Quote
* A flight to Mars is more difficult than Musk or anyone else thinks
* His plans are laughable
* The biggest problem on long flights is radiation. Astronauts are going to get fried
* The long time in 0 gravity is difficult, astronauts will not be able to walk once on Mars
* Musk does not advance space flight, he just distracts from other things
* NASA should not get hypnotized by people like Elon Musk, new satellites for communication, weather and climate science are more important than helping Elon with his Mars mission.

I find this extremely depressing to see. Its unfortunately widely distributed and repeated by other media sites. What motivated him saying stuff like that? Not only is at least half of his arguments wrong, but even if his problems were real, shouldnt he fight on the other side of the fence, given his history? I dont get it.

I was involved in an argument in another place about Elon not doing anything to expand the frontiers of knowledge.
Following a question 'Don't you believe possibly reducing the price of a moon landing by 20000 is expanding the frontiers' - and getting the response 'The Nazis had reusable rocketry too' - I dropped out.
Yes, the ME163 was indeed a reusable rocket, sort-of.

I do. The answer is old age.

Some people age gracefully, with a fully functional brain capable of adapting to change, right until the very end.
But other people, when going old, experience something that is best described as "mindset lock".
I've seen it happen to several people, not the least of which was my own farther-in-law. When it happens you can argue all you want but the person in question will not change its opinion, no matter what evidence to the contrary is presented.

Looks like he's just saying that NASA shouldn't get involved with SpaceX beyond purchasing services from them. I think this is short-sighted but shouldn't affect SpaceX's plans for Mars (IMHO).

Are there any videos that clearly show the 1-3-1 sequence in the landing burn? Every video I've seen looks like it could be single, whereas the entry burn's 1-3-1 sequence was clearly visible. I know it happened due to how much shorter the landing burn was, but what clues am I missing in the videos?

Watch the official SpaceX video:


Scroll to 29:45 in the video (T+07:45). Initially, only the center engine starts, but after about 2 seconds you can see another two starting as well.

GO for launch, GO for age of reflight
