I always try to watch the webcasts and I can't help but cringe so hard when they start chanting 'USA USA USA', every single time. What is up with that?

As a Brit we don't have anything as catchy. UKGBNI, or even just UK doesn't have the same ring to it. 'Enganld' wouldn't work because we're too diverse. It would be a bit like the SpaceX folks cheering 'California' in that I'm sure a lot of them are from elsewhere. I've come across it in a few other contexts and I take it like a football chant.

Finally, someone who fucking gets it.

HN is such a Mecca of sperglords that the can't even understand a sports chant.

Pretty sure he means the barge would sink from the big hole he thought the rocket would put in it.

Of course, but my point is that the barge is so much more massive that the idea of punching a hole all the way through doesn't really make sense, and even if that were possible, such a small hole wouldn't sink it anyway.

I'm a lot bigger than a bullet but it can still punch a hole through me.

Can someone please explain to me how the falcon orients itself during this total process?? Does it use fins, or simply engines and whatever those little jets are that, say, the space shuttle had around its nose... How does the falcon manage to physically orient its body? Also, is that process completely autonomous? Is there a remote flight engineer steering this to the barge - or is it completely self-guided

In space it uses nitrogen thrusters to orient. Once in the atmosphere it uses grid fins to orient. The entire liftoff and return is piloted by Falcon's flight computers -- no humans involved.

Ugh, I completely agree. I'm Canadian and it's been a dream of mine for a long time to work for SpaceX. I'll gladly take a big paycut and live in bumfuck nowhere, California to do it (my wife is another story but that's a different discussion). But every time this USA chant comes up I just imagine what it would be like to be in that crowd and be absolutely exhilarated at each success - not just for the company but fo…

I attended a conference from the head of the CNES (Centre National d'Etudes Spatiales, ~ French NASA) in Paris a week ago and he talked about that. Ariane 6 is going to be built with a cost effective approach and trying to focus on market needs (3D printing of parts, reusability of the first stage, etc.) At first, concerning SpaceX, his group of experts told him that the design of the rocket wasn't going to work and…

I can't imagine how anyone with the slightest clue could conclude that the first stage would sink the barge. The scales are just too different; the barge outweighs the rocket by orders of magnitude. I hope this is one of those "lost in translation" things, because otherwise I fear for that group of supposed experts.

The previous attempt literally did make a big hole in the deck.

the world has changed... in older generations you were allowed to be patriotic without being dumped on

I think you were supposed to be patriotic, with the cold war and all. Now a days, you are supposed to understand that governments indoctrinate patriotism and purposely inflict unneeded international distrust and tensions for their own selfish agenda.

Oh my god. We've reached peak smugness.

Close it down boys. HN is over. No more fun.

Am i missing something, is the need to land vertically a requirement of a fragile fuselage? Seems wasteful to carry extra anything (in this case rocket propellant) to space, just to avoid having to re-right the rocket when you get it back on earth for a subsequent launch. Is extra fuel payload < landing gear or parachutes?

If it's such a good idea, why don't all airlines use it for airplane landings?

Airliners don't land on their tails either. If that's your model then Adeline is the correct approach.

Well the advances remain to be seen in the decades to come. I could understand that level of excitement for putting a person on Mars but not for a satellite deployment or ISS restocking mission. Maybe it's just a cultural difference but there is something unsettling and cringey about seeing those employees act so enthusiastic. Is it genuine? Maybe for some employees. But the camera setup makes me think there is some…

>I could understand that level of excitement for putting a person on Mars but not for a satellite deployment or ISS restocking mission. I have seen that level of excitement over a soccer match. I think your priorities are personal, and you should maybe not project them to other human beings. Not everything is objective.

Soccer and sports in general are the spaces reserved for tribal and pre-civilized behaviours: rooting for one team against another, chanting, cheering for a victory or for the defeat of the opponent (in confrontations that are purely symbolic). Those who take this behaviour outside of the stadium often tend to salute their comrades with a straight arm, and resort to knives and sticks to prove their superiority outside of the pitch.

Or, you could see it like this. Europe has seen enough of nationalistic pride and of masses chanting in the streets. It didn't end well, and we know it. The USA don't happen to have made the experience yet in first person, though they certainly have a second hand knowledge of it.

Pride in the accomplishments of your own nation is a good thing. However often it clouds your perception of its faults and wrongdoings.

> you just KNOW What a complete load of utter tripe. Its a bunch of people getting excited and happy and celebrating success. That's it. Are England supporters chanting after a soccer match aggro-patriotic douchebags? The SpaceX crowd aren't even celebrating a victory over anybody, it's purely about achievement. Good for them.

>Are England supporters chanting after a soccer match aggro-patriotic douchebags?

Yes
