A Few times?! but its not a nervous "tick," Speaking in public can be stressful, so people will fall back on things to do say to fill the dead spaces. its just a different version of "umm"
Thanks for the update and videos of progress. The focus on the earth/ mars transit is understandable given the difficulties involved but I was a little disappointed in the lack of vision presented on the colony development itself, from the early exploration phase to find the important resources, to colony autarky.
I'm confused by the idea of "milli-g" fuel transfer. If there is milli-g's of acceleration on the fuel of the tanker, it would seem to me, that the RATE of fuel transfer in these conditions, especially when it would have to go through some interconnect valves that would restrict the flow of fluid, would take a very long time for it to transfer a significant amount of fuel. Are there any calculations to support this method of fuel transfer? Wouldn't it be better to pressurize the tanks of the tanker and let it flow (from pressure gradient) to the empty tank. What does the milli-g acceleration add to this? It seems insignificant. Any hard numbers for it?
Maybe would use both methods, without any acceleration fuel will not stay on the bottom of fuel tank (will splash in some ways and from bubble in the middle) , acceleration is needed to separate gases from liquid then can use pressure differential pomps or simply flushing in a large pipe to transfer propellant from one vehicle to another.
an object would eventually fall fast in milli-g environment. it would accelerate slow. so it might take a while, but flow would be fast after, say, a half hour or so
@@theOrionsarms Maybe they could have a balloon inside the Tanker's fuel tank (is there any cryogenic balloon?) that expands to push the fuel to the Starship's empty tank..
@@abptlm123 using cold gas thrusters for moving fuel in a side of fuel tank is proven technology, it's used in upper stage of falcon9 when reignited its engine in the orbit, expanding balons or rotating roket for separation of liquid from gas are theoretical concepts that nobody using at least to my knowledge.
Would the first starship to arrive on Mars be uncrewed? And if so, will there be some mechanism to autonomously unload the cargo? For example, if they wanted to set up a fuel depot before humans arrived.
Definitely uncrewed, they need a propellant depot up and running before humans arrive. My best guess is that they will attempt to set up an in situ propellant depot within the belly of the first starship. Or a pre assembled, small propellant depot which can be dropped from the cargo bay with no assembly required. We won't be able to control any construction robots in real time, so any construction will have to be autonomous and there are too many places for errors there.
The ceramic tiles on the Space Shuttle were problematic as I recall, though I suppose the Starship is less dense hence less subject to thermal stress. However the Shuttle was also intended as a reusable system but ended up with a turnaround of many months and more than a billion dollars per launch so I hope they can really hit that fully and rapidly goal. Of course the Shuttle being operated by a government agency probably didn't help.
If you are only going 78 m/s in free fall, that is only 180 mph. Couldn't they design the seats to withstand a 180 mph accident in a worst case scenario? Pressure suits and airbags. There will be broken bones and potentially even deaths but most people should be able to survive a worst case scenario (i.e. if the engines don't light for some reason).
If I am not wrong, the special Stainless Steel they are using is the grade 301 kind, with the following physical properties: Density: 0.285 lbs/in3 7 .88 g/cm3, Electrical Resistivity: microhm-in (microhm-cm): 68 °F (20 °C): 27.4 (69.5), Specific Heat: BTU/lb/° F (kJ/kg•K): 32 -212 °F (0 -100 °C): 0.12 (0.50), Magnetic Permeability: H = 200 Oersteds: Annealed < 1.02 max, and Melting Range: 2250-2590 ° F (1399-1421 ° C). from: www.combmet.com/301-stainless-steel-alloy/
People have spent upto 9.5 months on the international space station. But after a few months they really need rehabilitation to get used to earths gravity, and to recover in general. Its likely the effects from a full mars mission would be pretty debilitating
Looks like just about the same as trying to control a falling brick. Difficult. Cant imagine that orientation readjustment will go all that smooth. Hope it was tested many times in a simulation.
Well Dang, I can hear this one. THANK YOU ! Man on Mars ? I love the way Space X is building these things in the Open Air. Some what like a Shade Tree Mechanic would build a project. I actually find it comforting. Elon and Space X IS going to get Man to Mars. I've seen the first Man in space. First Man on the Moon. I really wish to see the First Man on Mars before my End Game. NASA had over 50 years to get the job done. FAIL ! Look what Elon has accomplished in less then 2 decades. I seen the first man in space. I seen the first man in orbit. I seen the first man on the Moon. I've seen static Space Stations Come and Go. I seen man chasing his tail getting little actual progresses beyond that accomplished. Get Man on Mars. That's what I want to see next. I'm getting Old here. My END GAME is coming up rather fast. Step it up a notch or two, Eaaa? NASA is just too Bureaucratic to accomplish anything meaningful any more. They could have and should have had Man on Mars Decades ago. ! You want to learn to live in Space ? LIVE IN SPACE ! Build the Braun Wheel Station and progress. Take the Path and progress. NEVER let up. NEVER deviate. Every dollar going to the same program. This is more then doable. The BFR being the basis for it all. Build a butt load of BFR's and use the aged and worn BFR to build the Braun Space Station. Quit messing around. Build the Braun Space Wheel and migrate it to the Moon or even Mars. Forget about all these side roads. The Braun would solve the Gravity Health issues, Eaaaa? Provide a solid sustainable long term platform to deal with Mars and or even the Moon. Knock Off all these side roads. Every step needs to be forwards. I'm getting old here people. Don't let me down . I really need to see a man on Mars before my END GAME.
Bjørnar Iversen I didn't notice him saying "y'know" at all until you mentioned it because I was interested in the content. Its just a fill in word and doesn't sound that distracting to me because he talks quite fast. Doesn't sound as bad as AOC saying "er like" every other word. I found myself saying it a lot in formal interviews so I tried to vary it with "sort of" and "kind of", mid sentance which are more meaningless fill in phrases like "errr" or "errrm" for when you're try to think about what to say next and being more guarded about what you say and don't say. The German's say "also" (alzo) which is distracting if said all the time.
Bjørnar Iversen I'd agree with you a little bit that he isn't a great public speaker, but he could have been much worse. He's probably more used to engineering and designing rockets, so less of a people person. That why these companies have public relations people, but then they might just give you a superficial overview, as they're more like sales people. Elon Musk is not the best speaker, as he stutters and is nervous but he's improved over the years. I'm sure these things come second to getting the rockets to work.
Who cares if he is a good spokesperson or not, he's not just some nice sounding PR dude like every other company has, he is the Principal Mars development engineer, he is the most qualified person in the world to speak about it. This way you get much more substance and a true look at the vision in play rather than a manufactured speech made to sound good to the public that is void of everything of importance.
Concerning the speaking tick comments...obviously Elon has been notorious for at times being the worst speaker ever but apparently, that has no bearing on genius or capability so who gives a flying fuck.
Awesome as always! i love the periodic updates we get from Paul on their plans. Thank you for uploading.
Have aready seen this but watching it twice. Plus the volume is way better, i can actually hear it this time (on phone)
This guy is awesome he is obviously intelligent. He does say "you know" a few times but it seems like a nervous tick . Thank you for the presentation!

Do you have the footage of Gwynne Shotwell and Gary Henry at IAC ?
And the interview of Lars Blackmore by the University of Cambridge?
The ceramic tiles on the Space Shuttle were problematic as I recall, though I suppose the Starship is less dense hence less subject to thermal stress.
However the Shuttle was also intended as a reusable system but ended up with a turnaround of many months and more than a billion dollars per launch so I hope they can really hit that fully and rapidly goal.

Not primarily being made of Aluminum and polystyrene should help.

wait a minute doesnt metal expand and retract according to temperatures???? I just dont see this working in stainless steel........I might be wrong

What about the lack of Gravity in-flight? It wasn't answered, 4-6 months with little gravity is not going to be good...
People have spent upto 9.5 months on the international space station. But after a few months they really need rehabilitation to get used to earths gravity, and to recover in general. Its likely the effects from a full mars mission would be pretty debilitating
on mars should be fineish its the trip im worried about don't want to turn up to Mars not able to withstand its gravity
