@Valansch Thx, I think they're starting their own space program using swarm intelligence to solve problems they can't. Once they've colonized Titan they'll just laugh at their subscribers and point and their 'terms of service'.. brilliant !

Why not use titanium? It’s stronger than other metals but also way lighter.
Aaron Washburn
Aaron Washburn - 5 hours ago
@Geohie Kim are you insinuating that titanium is heavier than stainless steel? Titanium is about 60% the density of stainless, ~4.5 g/cc compared to 7.9-8.1 g/cc. There are only three structural metals less dense than titanium: aluminum, magnesium, and beryllium.
Wyatt B
Wyatt B - 12 hours ago
SpaceX is going to mass produce these. Titanium is too expensive. Stainless steel checks off all the requirements like titanium.
Geohie Kim
Geohie Kim - 15 hours ago
@Alpha Bears uuhh, definitely not. It's quite heavy. it is, however, quite good in the strength-to-weight department. but for rockets, lighter is better than stronger, at least if they're similar in magnitude.

If these frigging people are so brilliant and want to be efficient make the material half as thick and 10 times as strong by machining the triangles at 1/10th the size. seriously WTF. How many stupids make a rocket scientist?
Geohie Kim
Geohie Kim - 20 hours ago
but that won't help with pressure, or possible leaks due to puncture from the thinner wall. they likely have thought of this, (also the smaller the triangles are, the heavier they collectively are, defeating the purpose)

All the houses built in the last 20 years will melt into the dirt in a few more years or so, thats when the dozers cram them into the ground to forget about the expensive trash we're making these days. Fast forward to Earth circa 2600 and hey you guys look what i just found in the ground??!?! Earth treated plastic called Tyvec or dupont or something. Once the forces that make diamonds are applied to this horrible idea called home-wrap, we're gonna have ULTRA-LIGHTWEIGHT plastic which is virtually INDESTRUCTIBLE!!!! Thats whats UP!!! the perfect starship material!!!! Those corporate bozos may actually do something worthwhile......eventually. Maybe. I guess.

@Jason Walker there are millions of women who use the same amount of money with one freaking Musk. What kind of comparison is that? Anyway, the world will end before we gona hv the need to go to mars. Trust me. No reply needed
Jason Walker
Jason Walker - 8 days ago
US women spend more on gel nails every year than Musk will spend on the entire Mars rocket development program. You don't even want to know how much gets spent on useless pastimes like organized sports, where fat lazy people sit on their butts and watch other people exercise (this is about the stupidest waste of resources on our entire planet). The entire world's space budget - military and civilian alike, government and commercial alike - pales in comparison to the overwhelming waste that you and others like you engage in on a daily basis.

Stainless steel is a bit of a marketing term. Depending on things like quality and how well it is processed before the end user receives it but even stainless still can and will rust in the right conditions. if you find metallurgy a little interesting I suggest falling down the stainless steel rabbit hole on the internet, it is pretty interesting.

For fuck sake we don’t need rockets to go to space,we never have.Our space fleets don’t use rockets nasa and Elon Musk are going to be remembered as a joke because we have been going to mars for decades and humans live there.We have been going to other galaxies and we have space stations throughout the galaxies.The world needs to know the truth and we need to destroy the people in charge because they are only looking out for themselves not the world.we have antigravity technology medicine is extremely advanced which is only for the military and really rich people.The international space station is a joke and they won’t be remembered for the good they do which is not a lot they will be a joke and remembered as pathetic.

No I’m not making it up. Go through the nasa videos and the rover photos, yes it takes a while to go through but thankfully nasa doesn’t cover everything up they miss things. It’s a slow process but it’s worth it. It’s the same in Antarctica they try to cover things up that they don’t want us to see. Also reading a lot of books and looking at what archaeologists say the ones from a hundred years ago and see what they have said first hand. We can’t trust archaeologists say now because for a start humans have been around 600 thousand years, we are not using the right dates. Look up Nicholas Tesla and Erich Von danican, jason rice, Corey Goode, emery smith David Wilcock, Churchill, and look up hitler there is loads of evidence that proves hitler lived out his days free, I even found a photo of hitler with his Spanish girlfriend in New York. I believe the world should know the truth and now previous generations have passed the truth can come out but certain people and governments don’t want the truth to come out and I’m putting myself in a dangerous position by telling people the truth but I believe that’s the right thing to do. Everything to do with the space program is all contracted out to private companies because the public can use the freedom of information act and this can’t be used against private companies. A big red flag that Elon Musk is wanting to have a private company this proves he is in the secret space program. There are 2 sides to nasa there’s the one we see and the one that does the secret space program. Nasa held a 2 hour press conference and confirmed aliens are here, they only admitted to 4 races but it’s a start and it didn’t go on the news channels for obvious reasons, they did this to cover there asses they don’t want people saying why didn’t you tell us and now they can say they did. I don’t know if many people know this but news is all controlled, we only see what they want us to see it’s called a blackout and the law stops it from being released. For the record Russia and China speak openly about aliens and ufos. In the uk one of our airports was shut down and they said it was because of a drone it wasn’t a drone a ship without permission was in our skies. Governments and the 13 bloodlines who are really in charge like to discredit people and call them crazy if they don’t want the truth to come out and they still do it today and it’s not right and it needs to end now.

Sorry I should have said free energy technology and it is in use. Nicholas Tesla invented it but like now governments didn’t want this technology being used so they told everyone that Tesla was nuts and they burnt down his lab. We know this technology works because it was built and shown on tv I think it was the history channel, they built it from scratch.

Emily Truman I should amend that, “free energy” does exist in the form of solar, wind, hydropower etc. but not in any mystical device capable of pulling useable amperage out of the air.
Aaron Washburn
Aaron Washburn - 6 days ago
Emily Truman there is no free energy. Yes, there are radio waves constantly bombarding us, but the power density of these waves isn’t even high enough to light a lightbulb. You can power things remotely, but that requires amplification which is not free. And perpetual motion machines are doomed by thermodynamics and uncontrollable losses even in the most efficient machines.

I would love to see a video about how a rocket fuselage can support all the weight of the upper stages when it is only made of a cylinder of very thin sheet metal. It's just mind boggling why the Super Heavy won't just crumple like paper when the starship is put on top of it. Then when you add the fuel, and then cargo, and then put it through the acceleration and dynamic pressure. That sounds like putting a bowling ball on a paper cup and then shaking it. Also, why don't they criss cross the interior of the tank with truss structures and guy wires? This is an engineering miracle that is very mysterious.

Not taking the Michael... Can one of you engineers explain to me how 3 men got to the moon in 69 when, according to NASA, we don't have the capability to go above low earth orbit now. There is a great big fucking elephant in the room which tends to make any interplanetary adventure look like horse shit. What exactly have NASA done in the last decade for trillions of dollars a year... It's the greatest commercial scam in history.
ŠQÛ!DƜȀRT T. - 6 days ago
nah man. We did go to the moon because it was a space race. When the space race ended there wasn't any motivation to go to space anymore. Now the space buisness is joined by the private companies. Now there is moitivation because these companies don't want to die. We have the capabiliteit to go above low earth orbit. The falcon 9 launched a satalite to geostationary orbit a few days ago. And now they're developing a bigger better rocket that can go to Mars and the orbital prototypes of these rockets are almost done. So no scam. Maybe Nasa is a scam, but SpaceX is not a scam.

1543 - Jesuits invent Theory Heliocentricism
1582 - Jesuits invent Heliocentric calendar (Pope Gregorian calendar)
1651 - Jesuits invent Theory Mapping Moon (Selenography)
1763 - Jesuits invent Theory Atomic Energy
1809 - Jesuits invent Theory Transmutation of Species (see Theory of Evolution)
1923 - Jesuits invent Theory Missing Link, (bones lost molds prove find)
1931 - Jesuits invent Theory Big Bang, (another ejaculation into the virgin source)

As shown, the Judaeo-FreemasonryVatican (Jesuits) instituted Heliocentricism (a corporation that has fooled billions of people) as the next centuries ticked by these science fiction stories began entering the major Universities (all faith based); from this point on the people were taught to replace Faith with Theory (pretend).
