There's something awesome (in the literal sense) and unsettling about watching something and being able to say "I am witnessing history".

Strictly speaking, every time you watch something you're witnessing history.

Please don't post unsubstantive comments here.

Correct, the engines were going to be retired anyway but they are keen to reuse the titanium grid fins on the boosters which cost a small fortune to make. The core actually had older ablative grid fins made of aluminium so no great loss there[0]. [0] https://i.redd.it/l6s2bds7pl801.png

Have you seen an approximate price for those fins anywhere. I saw the interviews, but I want to know how expensive is expensive.

Platinum is USD$32K per KG, so if the platinum grid fins are 100KG, then they would cost > $300K each just for materials. With 4 per booster that might be a million dollar price tag for the grid fins.

That was like watching a sci fi film when the two cores landed.... I watched it with my mother (who is 80!), and she said it was as significant as the moon landing. Do we know the fate of the centre core yet?

> Do we know the fate of the centre core yet? I might be reading into something that's not there, but the presenters (I didn't get their names) acted like they received surprising news in thier monitors at 39:03[1] just as they were about to report on the drone ship landing. Dude: "We've just gotten confirmation..." Lady: "oh!" Dude: "Oh" Lady: "[laughs] We are waiting to hear what happens..." 1. https://youtu.be/wbS…

I think it was the right move, even if they knew then the main core had blown, it is too easy for the naysayers to make that the story. Taking away from the real and powerful narrative SpaceX must tell. That for the first time since the Saturn V we have a rocket powerful enough in active service to take us to the Moon/Mars, at a 1/3 of the price of the next heaviest lifter.

Someone asked me to be a reference, I said no, they still put me as a reference anyway. I was not happy. Didn't badmouth him, but I also didn't say anything good about him. And when asked if I would hire him where I worked, I said no.

I asked permission from all of my references beforehand. Two were coworkers and the last was my previous team lead. I knew all of them had positive opinions regarding my work. The problem was BlueOrigin’s reference-questionnaire. One of my references shared it with me afterwards. It’s a stock template - except pretty much all the questions seem contrived to find reasons not to hire someone. One of the questions was a…

> Another was (almost verbatim) “Please provide a reason why we should not hire [candidate]?” (As opposed to “Can you think of a reason?” - I was surprised that the question straight-up assumes there is a reason).

Think outside the box. Reply with, "No."

The fins are titanium, not platinum. The cost of material is negligible.

Thanks for the closure - I've been refreshing twitter all morning. I've seen the much-touted $90M price-tag for the FH launch, but does that take into account loss of the core or boosters?

The damage to the ASDS might be more of a problem. Depending on how badly it was damaged, it might not be available to catch other cores that could have landed otherwise

It look cool to have them land on their own, but wouldn't it be much cheaper to use parachutes and drop them in the ocean !? Either way they are going to take them apart down to each bolt and then reassemble again to make sure there are no faults. You don't simply fill it up and relaunch.

You made an incorrect assumption based on bad logic. The parent didn't say they didn't look like rocket scientists, he/she said that they could pass as PR people, regardless of whether or not they were rocket scientists. Let me phrase it a different and rude (sorry) way. "You know they're including real engineers because there is at least one person in the spotlight that would never be employed by a PR firm."

> The parent didn't say they didn't look like rocket scientists That's exactly what the parent said. Let me quote it for you: > He doesn't look like a TV star, he looks like an engineer, a rocket scientist. He looks real. The implication being that the other hosts looked fake, not like engineers or rocket scientists but like PR people. I think you're being overly charitable here, but even if you're right and your int…

>The implication being that the other hosts looked fake, not like engineers or rocket scientists but like PR people.

You made the same incorrect jump! The implication is only that he's definitely not in PR so he's probably a real engineer. The others have the looks to be in PR (which is why he "wouldn't be surprised" if someone said they were). Yet he never said they couldn't also be real engineers.

They are just attractive enough that it's ambiguous as to whether or not they are real engineers or just PR folks.

Devil's advocate, here. Am I the only one that find it quite disturbing that a private corporation taking over more public space? In the long run this stuff will bite humanity at large in the butt.

In what way are they 'taking over', and what space?

I would claim they are expanding the market and generally that is beneficial for all stakeholders.

We are not discussing a finite resource like forests, here.
