Do customers get a discount for launching on a used rocket?

The first one definitely will (unless negotiations break down and they decide to launch without a customer, but that seems unlikely). Eventually when it becomes routine maybe not.

Securing is purely a safety precaution, it's not actually required. https://twitter.com/elonmusk/status/726218218109444096

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…

It is amusing that you insist your speculation about something you've never done is more valuable than the experience of someone that has pioneered it.

Actually no they did not weld anything to the legs. Elon said that they realize it wasn't needed. They did use octojack though to support the weight off the legs.

What's octojack? Can't seem to find any other references to that.

Sorry meant Octoweb jacks

If the problem is simply the seawater, you could use a large plastic liner to create a pool of fresh water floating in the sea, and land in that.

This pool of freshwater would need to be many kilometers in diameter to give a high chance of hitting it with an unpowered parachute descent (thanks to unpredictability of the winds). At this point you are talking about doing something that is much, much more expensive than the current approach of a powered landing. How are you going to get so much freshwater out into the sea, anyway? That's way more water than could…

A freshwater lake would seem easier

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…

Have you considered if your instinctive discomfort with group identities might make it difficult to understand the genuine differences in mindsets and worldviews that arise between different groups of people? I ask because it seems that people who reflexively dismiss the importance of groups can make as many errors in judgement as those who reflexively adhere to group identities.

What numbers? Unsecured cargo is unsecured cargo. A metal object sitting on a flat metal deck gets tied/braced/chained.

By the time the rocket lands, there's very few fuel left, basically you see a near empty Pepsi can. It's as stable as it can get.

Ever see an empty pepsi can in a stiff breeze?

Check out the history of the person you're replying to. That person doesn't get stoked about anything. It's a shame, really.

Getting stoked about trivial stuff and mistaking stunts for real achievements is one of the ways we will end up in Idiocracy. I see here, a whole generation of people reduced to a bunch of stupid cheerleaders... The shame is on you. Not because you play along in this charade. But for how you see and project me for not taking part in it.

Ya, because SpaceX is the only company to have ever transported something on the deck of the ship. It was a rocket until the moment it landed. Now it's cargo.

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'm an American, and I'm just wondering why it makes you uncomfortable? Does chanting at sporting events make you uncomfortable as well? edit: Reply button showed up finally

Watch a Hitler rally and that feeling you get is what I feel about chanting, clapping nationalism.

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.

and it won't affect your buoyancy at all.
