Now that the CRS-16 capsule has berthed at the space station with a load of Christmas presents and other essential supplies it's time to look at what we've discovered in the last few days, and clear up a few misconceptions.
In particular I want to thank John Kraus for taking some great photos of the event - which is pretty much exactly what he does -check out his work and support it here:

Some important updates on things which I probably got wrong: * The external camera is in a different place, so that bundle of cables at 3 O'clock isn't a camera. * Most people believe the pusher mates with the narrow throat of the engine rather than the top of the combustion chamber.

Rp-1 is kerosene and its basically highly refined diesel and at a high enough pressure it will self ignite from pressure alone I would need oxygen but its definitely something that would be thought of and probably be a reason to not use it for hydraulic fluid.

Yeah, it makes a lot more sense. As the injector is the more important part of the engine shouldn't be kicked out with a He presurized piston. 😉

I still think it's funny that people are calling this a failure. The previous generations of boosters just chucked spent stages like a drunk jerk with an empty beer can.
Влади́мир Пу́тин
how possible is it for a f9 booster to have a failure where the booster lands/crash into infrastructure or population. (Something like the boost back burn being to long.)

@Mein Kamph is that what your problem is? You didn't get a participation trophy? You've got to equate yourself with the most evil person in the history of the world because you feel left out? Very simple. I asked you what seems like magic to you - and you claimed all of it. Well what the man's talking about is science not magic. Magic doesn't exist. So the question is, why does science sound like magic to you? Now if you wish to participate and earn your own trophy, all you really got to do is say why something seems like magic to you that anyone else can understand. Now maybe you're a troll maybe you're a moron - maybe you're both. But if you'd like to actually learn something then by all means present a genuine question.

That was a perfect landing, except for the fact that is was not supposed to be on water. From what I've seen, the booster failures tend to happen on landing. So, failure that have no effect on the success of the mission.

firefly4f4 Pirms 6 Mēnešiem
I question whether the pusher is right up against the pintle injector. It seems more likely it's resting on the throat opening. If it was right on the injector, then that would mean the pole and that larger end would have to go through the throat, and it seems to me that would be extremely risky, as if the 2nd stage got just a little offset you'd risk damaging or catching on the throat when it exits.

I'm a bit late to this video, and have not read all the comments, but could those hydraulics be using RP1 from the main tank after all? On the exterior shots, I notice a channel that goes into the inter stage, at about the same place that the pipes on the interior shot go out of sight. Maybe it's been established or noted already, I dunno :)

Always wondered, How do the aerodynamics affect the re-entry of the 1st stage? I would have thought the engines would act as big scoops on re-entry, so much so, that the control fins burn red hot.

There is no heliocentrism, rotation movement / revolution, gravity, hubble telescope, 26000 satelites, round like a sphere earth, aliens, parallel universes, multiverses, political parties around the world are in fact just one, the same media for all and it is owned by the father of lies, the devil, nasa is owned, too, by the snake-devil, oms, onu, nato, unicef, cedo, fmi, etc. The reasons why the lies of heliocentrism are taught to us; - they want to manipulate us en masse - they want to minimise the role and the reason of the earth in Universe - they want to erase from our minds the existence of a creator - they want to bring arguments for the existence of aliens and other worlds - they want to discredit the reason of the birth in human body of God's son-Mesiah - they want to prove to us that we are some garbage of hazard - they want to discredit the reason of the Holy and Life creator's Trinity - they want to maximize an eternal reason of science and tehnology, we must worshipp them as our new idols - they want to teach us that we can become immortals / get redemption without the help of God - they want to make us believe that they already master the laws of universe - they want to overcredit the place of the sun and the Egyptian god Ra - they want to distract us from the reason of the antichrist's coming - they want to destabilise the perception of reality - they want to cancel the role of the holy bible - those that mock us / make fun of us are darkened by Lucifer Look what the Holy Spirit-God says in the Holy Scripture; Ecclesiast 1-5 "The sun rises, the sun sets down and the sun hurries to its place to rise again." Iosua Navi 10-13 "And the sun stopped and the moon stopped until God brought victory against their enemies" That's why it is written in the Rightous Book; "The sun stayed in the middle of the sky and it didn't hurry up to the sun down almost for the whole day"

The real treasure trove of such a landing is not the spoil of the booster, but all the data which have been logged during the landing event. This is why, one year later, the landing of the booster has been perfected and has become almost a show of engineering magic. All problems had had ways to show themselves, and they have been corrected one by one. Thanks to Mr. Manley for the video. I re-watched it after one year - with a different level of knowledge about SpaceX methodologies.

It always amazes me. In one hand, such a rocket is basically really primitive and easy to build. Not even a whole lot of tech is required. In the other hand, even though it is not really much that is required, tuning, tweaking and adjusting everything you have to make the rocket flight and behave like it should seems like an almost impossible difficult task. It seems like: Yeah, you got these parts, now make them fly into space. Just the fact alone that you have to make multiple tries but can't really determine what failed on the previous tests due to the rockets usually exploding. An intact but failed rocked seems like an increadibly valuable information.

I've noticed here and there in youtubeland that people are saying "Well, duh, put on a parachute." No. The idea is for precision landings. As soon as you put on a parachute, you've got things landing over large regions.

None of these photos or videos should be released without the approval of SpaceX and the US government. The best way is not to allow press coverage of the program. Manley’s effort to reveal trade secrets is proof enough that this degree of inspection is not in the interest of the company or the US. Deny him such opportunity in the future by keeping all photography far outside the range of inspection that gives foreign competition access to technology that the US has painstakingly developed.

Could someone tell me how heavy that rocket is and how fast is it traveling that you can't use anything else other than rocket boosters to slow it down for landing? Why aren't parachutes used or wings to make it glide down instead like a Joint Standoff Weapon?
stop begging for likes

wings are heavy, parachutes are inaccurate and you can't land on land and re-entry heating would melt the stage, the falcon 9 core stages reaches a top speed of over 10,000 km/h

The black triangular piece at 2 o'clock with two quick connectors looks like a fluid reservoir. The three silver canisters at 6 o'clock look like preasure accumulators. Using kerosene would not be that bad, it has lubricity and it's not that dangerous a fluid. And it's cheap. Someone's gonna say" its fuel, it's combustible, so is hydraulic oil sprayed out under pressure. If it just weeps a little, it's no more flammable. On top of the fact jp designated fuel was designed to be non flammable in liquid form. Look up the history of jp fuel, combustible but not overly flammable! Too many fatal aircraft fires.
