    bro you can read his posts they speak for themselves

     

    regardless, I don't think his other businesses will affect SpaceX. as far as I knew they're completely isolated

    His posts have always been a little crazy. Oftentimes it’s misunderstanding the situation, or humor that gets taken wrong.   There are things he has said and done that are disappointing, but he’s human.  People change over time so what he believed 10 years ago isn’t the same as now. Media does like to try and take down whoever happens to be popular at that moment.

    Probably. But if some capital investor bought Falcon 9 business, the price of launch would triple immediately and most of benefits of reasonable prices to industry would be lost for several years or even decades. Blue Origin seems to be maximizing profits instead of developing space tech and they would be happy if they could keep prices higher than SpaceX. Other companies need many years to develop large rockets.

    The way I see it going would be for Blue or somebody to buy the rights to Falcon simply as a shortcut for their own rocket. It’s more about the information they’ve learned landing 250 rockets than about the design of it. Im pretty sure that info would be worth a few million. And yes- they would most definitely not keep prices as low.

    . worst case scenario it bankrupts the company and we lose falcon.

    I think if SpaceX went bankrupt to that extent there’s someone out there willing to buy the rights to falcon 9, at least for the foreseeable future until they all get on the reusable bandwagon. 

  4. I had an idea and it’s probably dumb but here goes. Instead of a bladder to hold the liquid fuel, what about a bladder that holds a harmless gas inside the tank. To force liquid out of the tank you inflate the bladder with gas. The gas is contained in the bladder so only liquid is forced out of the tank by the pressure of the gas. In the receiving tank there could also be a gas bladder that starts full, but when you want to receive gas you open it up and push the gas into the full tanks bladder to pressurize it.   The empty tank bladder deflates, creates volume and reduces pressure, while the full tank bladder inflates, decreases volume for the liquid, and pressurizes the tank as it empties so liquid is forced out. 
     

    Just something stupid that popped into my head reading about the liquid bladders used currently for the ISS.

    If continuously transmit simple melodies (whistle with lips or drum with fingers), then sooner or later some melody will match the aliens': door lock, parked car alarm, launch code of a planet-killer missile, or so,

    Proposed space telescope constellation (8m objective!) launched by Starship:

    Cool to see ideas using the available volume.

    I keep seeing this layout, but I wonder if it would be better if the load were attached to the inside of the clamshell door?  Then they just have to slide off guide rail instead of at a weird angle.   Bad part would be the door would have to be able to support the load during high G launch

    It’s not so much that it will hover, it’s that it can… in contrast to Falcon 9 which cannot. This means that they have full control of descent speed right down to zero m/s, which will allow much more precise maneuvers than F9’s suicide burn, even if SH is actually still moving the entire time. 

    Yes but I doubt they could switch from one to the other mid burn. Either they plan to hover or they plan not to.  They’re not gonna bring down extra fuel if they don’t have to.  


    if they could hover to make themselves more accurate I would have expected something of the sort during the initial testing. They definitely  landed the prototypes off center ( I think the first one even had a leg off the pad). They also had all the fuel they needed to hover if they chose to. 

  8. I think people over estimate the ability to hover.  The ability is there but I don’t think we’ll see it used. We’ve all seen the landings of the prototypes. They don’t hover. Why? Because it takes too much fuel.  (Yes I know there’s a weight difference between the prototype and an actual rocket - doesn’t change the fuel requirements).   The only prototype that hovered was hopper, and that’s all it did.  I doubt they can switch from a suicide burn into a hover at the last seconds. It has to be planned ahead of time. 
     

    blue origin can get away with hovering because their payload is light and their goal is to get just barely into space.  Also it’s built into the flight profile.

    He completely avoided federal income taxes in 2018, I doubt he’s paid much since

    Completely made up his rags to riches story, in fact his father owned a emerald mine

    Freaked out and called a man a pedophile for not using his mini submarine

    Tesla is one of the most dangerous working conditions in the US

    won't let his workers unionize cause he’s too cheap to pay them living wages or give them benefits

    Was very dominant and abusive to his first wife

    Just to name a few from the top of my head.

     

    Several of those assertions are false, but even so, They make him human-not evil.  There is a huge step between being a jerk or an ass and being hitler type evil. 
    like I said, I’m not glossing over the fact that he can be weird and also do stupid things, but there’s no need to lie and make up stories if you don’t like him. 

  10. I’m not a Musk fan boi, but I do find it really weird how some people just can’t understand that being rich doesn’t make you evil.  They seem to spend their time trying to tear down anything he accomplishes, no matter what it is. 

    Is he a little crazy? - sure

    does he accomplish amazing things that cost you nothing (or next to nothing if you consider the small amount of funding nasa has given him)  and create progress for the entire world? - also sure. 

    making up conspiracy theories to tear him down is just ridiculous. There are plenty of reasons to like or not like him, making stuff up is what 3rd graders do.   Now if you have any evidence of any of that, then fine- let’s looks at it. But just deciding because someone is rich they must also be evil is wrong.

    I asked a similar question the other day* and folks were kind enough to answer.  Fact is that there are many here who are in the enthusiast-to-expert range of knowledge on this and other topics... and others like me that are basically interested Neanderthals who enjoy talking to the highly educated.

     

    Point being: sometimes its fun to chat with the community, even when a dry 'google' might reveal the answer.

     

    *I may not be a full-on troll, but I do have a snarky sense of humor.

    It’s not what he’s asking, it’s the way he’s asking, like he’s spoiling for a fight. He seems to think he’s so much smarter than actual rocket scientists and seems ver confrontational in how he “asks” questions. 
     

    those are the signs of a troll. It’s ok to ask legitimate questions.

    That sounds like a fun story but I cannot find tail nor feather of it anywhere -- tell me more!

    it’s easy to google: oilsands tailings pond ducks

    numbers of ducks range from a dozen to 1600 seemingly depending on what the initial bias against the oilsands is in the reporting. 
     

    as it relates to spacex though, it would be a huge PR bust- even for seagulls to be roasted live on camera. On the other hand they could probably try and spin this as the booster saving those poor birds on the landing zone. (Even though it’s not likely true)

    I don't mean to crap on Tim. Really, I don't. But asking "why don't more sea level engines use tapered vacuum nozzles" suggests he does not have nearly as deep an understanding of rocket science as he seems to hold out. It is kind of a waste of time to ask Elon dumb questions. If I had 1/10th the access to Elon that Tim has, we could REALLY learn some good stuff.

    Maybe Elon answers his questions cause he doesn’t go on public forums making an ass of himself by saying how dumb other people are. Just sayin

    Its extremly annoying to see this stuff only in videos. Its mostly still images, only people are moving a bit. Is there a summary with just pictures somewhere?

    I agree. As someone who looks at most forums on my phone data (which is limited) it’s frustrating that video is the go to format for showing still pictures. All we need is a picture with a small write up underneath. I end up skipping most of the video content unless it’s important enough to remember when I get home

    Controlling yaw with just two flaps in the coronal plane, actuating ventrally or dorsally, is impossible. You can control roll easily, though. Lift the left flap to decrease drag and roll left, and vice versa. Lift both to decrease aft drag and send the center of pressure forward of the center of mass, pitching up; extend both to increase aft drag and pull the center of pressure aft of the c enter of mass, pitching down.

    The reason for four flaps is that you actually can control yaw aerodynamically. Order the forward flaps to roll left and the rear flaps to roll right, and you'll yaw left.

    If you only have two flaps, you can't nudge yaw without a high AoA, but there's no barrier to using RCS for yaw with low AoA.

    You could always use a split flap like the B2 apparently does. One side splits up and down and creates yaw in that direction like a speed brake. 
     

    nevermind. I just remembered that the angle of attack is to great for this type of flap to really be effective.
