    Stupid Questions about Naval Aviation (Part 3)

    So I got hammered a bit in the Bulging Disc thread when I asked how does aviation wreck the spine (LINK) and one of the things mentioned was bad weather and vibration. I must have in my memory mixed that up as turbulence. But for the issues of bad weather and vibration, I would think a seat with...

    Stupid Questions about Naval Aviation (Part 3)

    So my understanding is turbulence can vibrate the plane and wreak havoc on the spine of the pilot over time. My question is, why don't they put some kind of shock absorbers in the seats? Like how you have hard seat mountain bikes (no suspension) and soft seat ones where there is a...

    The former program manager of Blue Origin's BE-4 engines has filed a wrongful termination lawsuit over (he says) being fired for blowing the whistle on safety violations at the company. Apparently the CEO of the company, who recently stepped down, had a very controversial tenure with allegations...

    If they lack a safety culture, then why does NASA entrust them to launch astronauts? Why has the Air Force given them the contract for development of a logistics rocket? I agree that there is a Musk cult unfortunately, but I do not see that affecting SpaceX's safety culture right now.

    SpaceX was ready. They don't just build the rocket and launch. They test fired on the ground both the Super Heavy booster and the Starship itself. But to really learn, they have to launch. As for Starship's ability to land safely on the Moon, NASA seems to think it is a good design. I am sure...

    They most certainly have revolutionized things. This is actually a very ironic thing I've seen happen: 1) SpaceX says they're going to achieve X 2) The industry says impossible, no, idiots, Elon Musk doesn't know what he's doing, can't be done, etc... 3) SpaceX achieves X 4) Industry and...

    Given their level of accomplishment thus far and the fact that they are actually launching Starships right now, it would be pretty foolish of them to have not started doing actual design work on the thing. From glancing at the Wikipedia, it says they initially constructed and destroyed via...

    I'd say it's likely more than a concept at this point. I am sure SpaceX has done quite a bit of actual design by now. And launching one hundred people into space may or may not be dumb. The point is to make humans a multiplanetary species, to ensure our survival in case something happens to...

    Not really a fair comparison though. Two very different vehicles. The Space Launch System is not reusable and as such, costs a lot more than what Starship will cost if SpaceX is successful with it. In addition, Starship is larger and far more powerful than SLS. Yes the SLS made it to the Moon...

    Yup, they have money to (literally) blow regarding these rockets. It isn't just the process of rapid iteration with rockets though, there are some other things. Big Aerospace apparently has a lot of legacy practices to it that are just there from decades ago but which are not really necessary...

    Saturn V had two (successful) launches before they put crew in it:) And sent them straight to the Moon to orbit (I think ten times) and then come back! Not saying they should only do two for Starship but just interesting.

    The Perpetual MEGA Space Thread

    I don't think that is a proper comparison though. Airplanes aren't giant bombs executing a controlled explosion. They also are reusable. Imagine if historically, every time the Navy sent up an aircraft, they had to destroy it after the mission. So the pilot would go up, execute the mission, then...

    NASA is well aware though of the difficulty involved in such a large rocket design, so I think they are willing to cut SpaceX some slack.

    Whoops, yes I mixed up the Raptor engines with the Merlin engines, which from what I understand are a fairly simple design. The Raptor is much more complex as its the first full flow staged combustion cycle engine to ever really be used. However, the current Raptor 2 is significantly less...

    How is it failure or dumb if they are continually learning and making improvements to the design each time? Also, they didn't launch without a plan to land. They were hoping to land the rocket. Nor do they launch with the intent to blow up "just to see what happens," they launch with the...

    Not really. And I don't think the two are comparable. Saturn V was an immensely costly undertaking and the rockets extraordinarily costly. Yes none blew up, but the issue is if it blows up when the rocket is supposed to be safe, not during the development phase. Blowing up rockets is part of...

    The Raptor engines used are fairly simple, unimpressive engines by the standards of rocket engineering. So they are fairly reliable.

    This was expected by many. This launch, SpaceX got loads of additional data, so their next launch may explode as well, but make it significantly further. This launch itself was improved by data from the first launch. Regarding the Super Heavy, from what I've read, it uses lots of smaller rocket...

    SpaceX already actually accounts for this. When a Starlink satellite dies, they have it designed where it will just burn up in the atmosphere. Something will need to be done eventually for all the other space junk up there though.

    SpaceX isn't the only one putting these mini satellites up there, other companies are as well and now China is planning to.

    I don't know if Zippy meant it this way, but "incel," while "technically" meaning involuntarily celibate, also refers to a subculture (?) of such men who hate women and much of society. The hate is because they can't get laid, however being involuntarily celibate by itself does not mean one is...

    I am surprised anyone in a high/respected/prestigious position would join something like this.

    Russia was/is the aggressor though. And fighting a war doesn't mean directly proportional numbers.

Almost all mechanical parts are made by machinists. Even a...

    The cheers were likely because they knew the rocket would blow, as it is the largest, most powerful rocket ever launched. The goal is to learn from the launch so they can figure out what went wrong and do better next time. That is part of their modus operandi. That isn't SpaceX's attitude...
