Technically it isn't fuel, but an oxidizer.A collection of liquid oxygen droplets ie. leftover fuel
They showed a video from the fuel tank too (more greyish in color)

It's an aluminum can and mostly empty. Not very heavy.
It most likely hit the barge too hard for its legs and fell over, bursting into flames.

cancelled, just read that:No press conference, then?

landing burn (from reddit, 15s exposure):
Actually hitting the target was the hard part, so this is an excellent result
Yeah, this result is surprising to me. They've done plenty of soft landings before, so I expected the most likely failure would be to just miss the barge.
This will probably turn out to be a stupid software bug, like someone forgot to merge in the change that adjusts for the height of the barge above the water

According to their tweets, the pad is fine. Other stuff, not so muchlanded hard?
I wonder if the sea pad is still afloat
Exactly. They got within one inch of a groundbreaking success. Nobody has landed an orbital-speed device on a schoolyard pad in the entire human history yet. The closest thing to that was the Curiosity Mars crane, and there the entire delivery vehicle was designed with that sole goal in mind, and the crane was subsequently disposed of. F9's 1st stage landing is as tough rocket science as it gets.Actually hitting the target was the hard part, so this is an excellent result
Man, I hope they release some footage of the landing sequence.
"Didn't get good landing/impact video. Pitch dark and foggy. Will piece it together from telemetry and ... actual pieces."
Nice.Grid fins worked extremely well from hypersonic velocity to subsonic, but ran out of hydraulic fluid right before landing.
Upcoming flight already has 50% more hydraulic fluid, so should have plenty of margin for landing attempt next month.
Autonomous barge way out to sea for that very reason :]Was that barge manned? I hate to be the guy that's sitting in the bridge, wondering if a big 'ol rocket booster was about to fall on my head.
They rock indeed.
Eventually, SpaceX wants all of its Falcon rockets to fly themselves back to safety — at first at sea, and then on land. Musk has said this kind of rocket reusability is an essential part of his plan to reduce the cost of launching payloads to 1 percent of what it is today. Over the longer term, he envisions making spaceflight cheap enough to allow for the colonization of Mars, thus making humanity "a multiplanet species."

I'm a bit disappointed that with all the cameras they had they made an excuse about fog for no pictures of the smash-up in the atlantic.
Could it be that they would prefer not to show the carnage?
Yes, I looked that up after posting, so it appears a disposable 1st stage reaches 10M at MECO (main engine cut-off), but a reusable 1st stage gets to 6M at MECO. In either case 1st stage separates a few seconds past MECO.Fact check :The 1st stage wasn't going that fast. ISS orbit is 17,000mph, but the the 1st stae only gets up to 4,000mph. Still plenty fast, but not "orbital speed" (and therefore no serious re-entry heating)

Testing something like that at night seems pretty stupid. I mean, wouldn't you want to get as much visual data as possible?

Not sure if they have a choice, to be honest. They got a very very small window for launch for the delivery. So they gotta do what they gotta do.

In addition to what people have already pointed out about paid launches and laugh windows, I would think that they must have telemetry data of the crash, and in which case, that will always been more useful than visual data from a camera.
SpaceX just tweeted a vine of the ship landing, looks like it tipped over at the very end.
They were out of hydraulic fluid, which means no more steering. That's why it comes down at the weird angle. If they had not run out, there was a good chance it would have come down correctly and landed properly."Close"? I guess it crashed where it was supposed to land, but that seems like a disaster to me. I wonder what happened.
"Close"? I guess it crashed where it was supposed to land, but that seems like a disaster to me. I wonder what happened. Was that really meant to land perfectly vertically? It almost looks like it was upside down...but isn't. It's going to be truly amazing when they manage to do this.

Uhh you missed the point in which even having the rocket come down in a small targeted area at all was the huge achievement. Before they just aimed to have it burn up in space or fall in the ocean somewhere.
