Just to elaborate: due to wave action and leverage on the underside of the hull, parts of the deck of a ship can accelerate downward faster than the acceleration from Earth's gravity, and while the deck underneath the rocket has fallen faster than the rocket and its heavy engines it can also lurch to a side. Even if the center of gravity makes it equivalent to a sheet of rolled steel, so that it wouldn't tip over, it…

Of course if there is any chance of the rocket moving, it isn't even safe to pull up alongside, let alone send people onto the deck to secure it.

There are protocols for securing unsecured cargo. Whether delivered by rocket or crane, things land on decks every day and are tied down by hand.

>diminish amazing things.. Sorry. We are living in a period where mediocrity and even complete fraudulent stuff is hailed as profound and "amazing". People with differing opinions matter, and I would say they matter more than ever. And I don't think people love being a contrarian". It is quite easy being a fanboy, but it is hard to go against popular opinion, and be a "contrarian". There is no love in being a contrar…

Even easier than being a fanboy is to promote one's own superiority via dismissal and sneering at the efforts of others. You probably see yourself as sophisticated, but your remarks are no different than a 7 year old putting down somebody for throwing like a girl. It's adolescent, not contrarian.

>Even easier than being a fanboy is to

Easier? How? Because you said so?

>promote one's own superiority via dismissal

How come I haven't noticed that it isn't working, then?

>sneering at the efforts of others..

This is where you show your fanboy colors. The GP said something along the line "I don't think that is as amazing as you say", and you overreact, saying that they are, "sneering at others efforts". Another commenter said SpaceX is facing "incredible" criticism in HN. All signs of over reaction, typical of fanboys when their need and expectation of unquestioning acceptance and praise from everyone, for their object of worship, are not met..

>You probably see yourself as sophisticated, remarks are no different than a 7 year old putting down somebody for throwing like a girl, It's adolescent, not contrarian.

More typical, hurt fanboy reaction. Stop for a moment and and think about what exactly in my comment have provoked you to attack me in this fashion.

You're getting downvoted into oblivion, but yeah, that's basically how I feel. Cultural differences, I'm sure, because I'm not USian; but every time I see it on the youtube videos it makes me deeply uncomfortable.

I knew I would get down voted, because the collective group-think mindset is very strong around this particular issue, and Americans have been programmed to think its acceptable to make these kind of cult-chants when they do something special. It is a special event - most definitely - but the cult-chant ruins it. Very obnoxious.

Honestly you just sound kind of brittle if others chanting USA! ruins something for you. Sometimes the USA chant is overdone but in this case I think it's awesome.

>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 outsi…

Or... they launch rockets into space, and land them back on a small platform.

That's the response I was hoping for. My only critique then is please register a personal account. You can't have a name like SpaceX_Tech and not expect us to take everything you say as something that they would endorse. I'd be appalled if a programmer I employed created an account under my company name, for use of expressing every personal opinion under the sun. I hope you understand the position I'm coming from and…

To be honest, I hadn't considered the ramifications of using the company name as part of my username. You make a good point about the potential of being mistaken for representing the company in some official capacity and I will heed your advice and register under a different username. I'm curious about the etiquette in regards to identifying myself as a SpaceX employee though. I originally joined to relay some of my…

Stick with your name. You earned it.

To each their own. What starts as an awesome technological event, ends with thought-stopping cult-like behavior. I guess the two are entwined, eternally, throughout human culture, so I shouldn't be surprised ..

I wouldn't think twice if you had in your profile something like "I work for SpaceX." Good to know, but not the source of your opinions. Your account is young enough that you can gain all that back without the boss in your name. This isn't my first account. Plus, and I can't speak for everyone, but as a former would-be astronaut, this kind of stuff is tops to me. Info from insiders is always welcome. Consider startin…

Thanks again for the advice, I certainly value your point of view. This is the last time I'll post from this account, I'll go ahead and start a new one at some point. I appreciate your sentiment in my starting a blog but I don't think I'd have the time to meaningfully contribute to it and I don't feel comfortable enough in my writing ability to do the kind of long form writing I feel such a topic deserves. There are…

I'd also advise you to remember that SpaceX isn't taking kindly to employees passing out internal information.

With respect to Musk, that is total bunk. Any structure like this will have to be secured to the deck. The fact that it is a rocket doesn't matter. He may think that it is safe from falling over, but the insurance company and/or the health and safety people will tell him that cargo that tall needs to be secured. Ropes, chains, welding ... it cannot just sit there. A Volvo station wagon, on that deck at sea, would be…

Cargo shifting is a big deal. The yearly casualty rate for Bering Sea crab fishing used to be over 1% per year, because the shifting weight of crab pots on overloaded vessels in heavy seas. I saw a training film when I was aboard a tender boat in Alaska. Those boats could look fine one minute then capsize and be as good as sunk in the next 2. Shifting weight on vessels has and does cause rapid capsizing and deaths at…

This is pretty light cargo relative to the weight of the ship. It's a few tons of rocket and thousands of tons of ship. I don't think it's going to matter to the ship if it shifts, the only risk is losing the rocket over the side.

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.

If a one gram bullet hits a 100 kg Athlete what happens?

There are several orders of magnitude there.

In my opinion, it may not necessarily be a national pride thing, as much as it's just an impulse. Because in sports, this happens often, I think it's more about showing how happy they are than crediting the United States for the accomplishments they made. As an American (and specifically, a 16-year-old Software Engineer), growing up in the United States, this is normal, and is sometimes patriotic, sometimes an automa…

Have you ever thought about how this pride for your nation, pervasive at the point of feeling natural, might cloud your judgment when dealing with other nations that might have competing, but perfectly legitimate, interest? In other words, are American citizens able to put themselves in the place of others, and judge fairly and dispassionately about international events? Because this is what I have strong doubts abou…

I think you're overthinking this cultural convention. It's like talking to a Japanese person and saying, "How you ever thought about how bowing instead of shaking hands de-normalizes physical human contact?"
