The daily problems on Brilliant are actually fantastic. Great way to challenge your brain each day. Thanks again to Brilliant for making these videos possible: http://brilliant.org/realengineering/

> The daily problems on Brilliant are actually fantastic... (blink blink) Okay, different type of problem than the daily problems on Patreon.

Utter fantasy, you will know this one day, SpaceX is a scam, a squillion dollar one who, like NASA; have done precisely FA in space. We have nothing up 'there' and never will, its not possible. Go ahead and rage, its cold hard truth and every human on earth will know it in the end. Check it out or be duped fools - your freedom of choice. Have a great day all.

0:45 ~ There were not "40 formulations" or "57 Formulations". It was #biblical {needs citations, would need to locate the times i found them} #YorkRite metaphor of lose your head=#40. ~ Spray #WD40 on airplane bolts during servicing bare threads and nuts; #PBLaster is a better penetrant or #capillarylube (#turgor air pressure helps), and the #gremlins of vibration would cause objects to fall from the sky. ~ if not done on the ground, happened via thread lube, the reason someone invented #ThreadLock and possible clue why their color is blue, to fight YorkRite or BlueWhite UGLE #roundhead mystery #WaterOfLife is bleeding or pressure releasing the blood of not our #clans (they intend to kill the letter K #klans, because that DNA is listed as enemy of England, and the Vikings never used Fire Funerals). ~ I personally like Red as the color of #ThreadLock, halt accidents and machine failures, rust is an enemy, yet you do want #galvanic or #ionic bonding (not #oxidants, #oxidative) or machine force mechanical #torquebinding.

And then spacex gonna make guns for the mars expedition

FakeX

its science jack septiceye

Why do you say 95% of the aluminum goes to "waste" when it is CNC machined... the shavings can just be melted down and made into a solid piece again.

as a materials engineer this video gave me a hard on

Bro fuck brilliant I don’t wanna sign up 😒, love your vids doe 🙃

That isn't a starship. By definition, a starship is a vehicle for traveling between stars. We aren't even close to that level of technology at this point in time.

If anyone says SSTOL sucks, they’re retarded in the sense of money and efficiency.

I thought aluminum was more heat resistant than steel?

+Michael David It's not that big of a problem outside the LEO (which has a lot of space junk). And even if that, somehow, becomes one - Whipple shields (http://en.wikipedia.org/wiki/Whipple_shield ) to the rescue!

+caav56 Thank you for replying. Aren't small meteorites the biggest threat to space travel? How can this be avoided?

It sucks in the metal fatigue department, though. That's why aluminum airframes have strict "flight hours" limit, until they must be scrapped.

excellent

From 2,5 to 10 (!) millimeters is extremely thin??? I guess there’s a mistake)

FYI that aluminum CNC'd away IS NOT wasted. It's collected, melted down, and reused to make new aluminum billets. At least it is in any other business besides SpaceX. I assume they do the same. No one would just "waste" that much aluminum and just throw it away, actually wasting it.

Where in aluminum is it pronounced aliminium

SPACE X ] LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL FUCKING RETARDED!!!!

8:26 "But nothing this heavy has entered the Martian atmosphere before, and it's not going to be an easy task for it to slow down" *A wild asteroid appears!* "Hold my beer"

I'm glad Elon musk is bringing back the old style like relanding

AlumiNUM.

Because the future is all chrome!

elon musk- hold my beer hahaahahehhhhhg

Donkeys years away,so don't get excited, as the military already have the tr3b,that surpasses this bollocks by a long way

Omg! do people still buy all this BS? it's the 21st century for God's sake get yr heads out of theyre asses!

Because its fucking awesome

"This results in 95% of the material going to waste." @ about 5:08. Ever hear of recycling?

I'm surprised how many commenters haven't ever heard the way "aluminium" is pronounced in the Queen's English.

`honestly, other than Musks tunnel idea, I think he will be one of THE masterminds that create the future

As a machinist with 9 years experience... I resent the idea of that an isogrid is very expensive to machine... I would estimate $150 per ft^2 in aluminium, -on the very high end. If it costs more, your machinists are padding.

NASASS you need to stop faking shits

BIGBALLSHIT BIGBALLSHIT BIGBALLSHIT

7:08 great pun

This shit would look bangin' in my kitchen.

It's H not Hach. Are you Indian or Irish? I can't tell.

This video is 10 minutes longer than it needs to be!

I care less!

I care less!

A big ship landing on mars would create alot of heat. Steel can withstand more heat that is why. there saved you 12 minutes of pointlessness.

you can't pronounce "Aluminium" and then type Aluminum.

Electric cars - first produced in the late 1800s Rockets - took men to the moon in the late 1960s Elon Musk - builds electric cars and rockets = amazing visionary

"...And this is where stainless steel really shines..." HA IT SHINES

"mersjen"

REALISE! REAL LIES! Fooling the fools....

Me human, me no know why smart human make metal ship, talking human help me human know smart human reasons. I now better human.

Wow!

So many videos so little time....

The Star HOPPER is just the short, kludgy test mule for motor and control testing. It ain't going to Mars. You meant Star Ship.

What's the matter? Ya got shite in ya ears?

Very interesting.

Make mistakes to learn that is what my dad did now he knows to rap it before you tap it

The sky is calling they love to mock #REEEEEEEEEEEEEEEEEEEEEEEEEE

So it’ll last longer and weight doesn’t matter because space is fake so it’s not going anywhere

You left out how this is just a quick slap stick setup for testing hopping, This rocket will NEVER go into orbit, This rocket is also smaller then the final product that will be built, the star ship will be built completely different and not in a open field.

the delorean of rockets?

This is basically the same video that Everyday Astronaut uploaded a week before yours... Hhhmmmmmm....

Because of all the imaginary giant magnets in fake space

Hey where is the 1.03 problem

Elon is the epitome of "Because I can"

"because i believe i can" but that wont work with everthing he does

I wish I could like this video more then once.

"you know it's real because it looks so fake" there you go, nuff said. Keep on repeating what you've been told.

Rocket fuel can’t melt steel

THIS IS WHAT I CALL SCIENCE!!

I Hope this will be an success for humanity👍

Space needs flat packs

5:05 , you say that CNC ing isogrid from thicker material produces a lot of waste (95%). This is most likely not true. It is recycled. It is easy to remove lubricants and remelt it, or as a part of another batch, and create another cast. It is just the problem of time and big machine required. These machines are rather costly, and it probably day or two to machine out one section even when toolpaths are optimized and very high feed rates are used with first past done using coarse milling and big tools.

Great video! I may check out your sponsor.

Get to the point fuck head! Or go find your Lucky Charms.

Oh? I am surprised that you are still will Patreon, I thought it's business model was "unsustainable" according to their CEO.

What is an “irt form?”

the thing looks like a z movie set prop or even a 50's movies rocket model.

Well, it's just a hopper-type engine and landing automatics test platform - they can allow themselves to make it look like this without losing any functionality.

Nice video, but, I have in the past 2 months have become a flat earth believer. I do NOT believe in outer space. It was ridiculous when I was a child, but I accepted it (stupidly I did), but now I trust common sense over NASA,

So it wont rust at the bottom of the ocean...

They made it just to look like a Naboo Cruiser. 😄

Magnetics not fuel.

Why do you pronounce Mars with an E. You say Mers. Lol thought you were supposed to be smart.

Wow I Just spent the last hour watching multiple videos from your channel and have learnt so much already your a genuine mastermind at what you do and you clearly spend countless hours researching and finding information to create these short but fun and educational videos, I'm a young recording artist but I'm always fascinated with modern science and engineering. I love your videos, Keep up the good work!!! 👌🏽💯

Whoever gives this video the thousanth dislike is an idiot, because why dislike the video?

Lotta video for not giving the answer... It's Radiation... Only the stage that will carry souls needs to be SS as radiation will bounce off of it rather then passing through or being absorbed and still have a chance at reentry. Twice! First and or second stages can be made out of whatever can hold, launch and push the fully loaded "Star Hopper" to Mars or wherever.

We are so backward as a species. My money is not on Musk because Musk is *Full* *Of* *Shyte!*

We must work on defeating aging. Mars will be here for a long time. But Musk's body will decay unless he invests into defeating aging

The picture in the thumbnail looks like The Planet Express from Futurama

It’s a submarine you morons

stainless steel is only one property of this steel. Nanotechnologies allows us to create today alloys that we couldn't made before .

These guys say aluminum in a way that makes it sound like it was invented in the future, in the MCU, and then traveled through another dimension and backwards in time using the infinity stones to get to earth. And that's where aluminum foil comes from.. I mean, "AL-you-mini-yum"

Still amazes me what people can do these days but we cant save the planet...sad.

fake !!!!!!!!

Cause Elon knows

A mission to mars is exciting and all but I can't help thinking that putting all that talent, effort, and money into fusion power generation research would be a better pay off for the resources used. So ya maybe one day we can go colonise another planet in the very far future but we need solutions to survive till then far more urgently.

You can not just call stainless steel steel

When are we gonna build mobile suites.

This is a Test Mule, a Sub-Orbital Motor testing rocket. Think Little Joe.

Or Grasshopper, their previous machine of the same kind.

Blessed to see every launch since 1990 in person living in Cape Canaveral

CANNABIS

U mean they faked a video of a cgi rocket launching.

This is where steel really.... *Shines*

instead of humanity focusing on politics, we should focus on such stuff as space travel!

It's odd that i never heard of them trying the aluminum and carbon fiber laminate which is carbon fiber between two layers of aluminum. It doesn't require the same autoclave curing as basic CF does and it's shape-able. It's not the easiest to weld but the results are impressive and it has a double hull like protection if something goes wrong.

'Shit Show' really. You were professional the whole way through and then throw in 'Shit Show' Kind of cheap. Next time skip it.

The StarSHIP is the full-sized human-rated vehicle that will go to Mars. The StarHOPPER is an unmanned test rocket that will only go to five miles of altitude and is solely used to test operations and the engines for the 'real' ship. You keep mixing the terms up and saying that the StarHopper will go to Mars.

7:04 - I see what you did there...
