      Maybe one thing missed. SS does not have the same fatigue problem as Al alloys, the latter having zero strength as endpoint. This might be of importance when using the spaceship over a longer period and for reentry and a second takeoff. Also, considering possible injuries SS buckles and bends without cracking compared to Al alloys.

      Sometimes I forget that humans are stupid and haven't yet figured out how to grow biometal or flexmetal, like how they grow organs now, but using an interlaced combination of Bark Spider silk and Ironclad Beetle exoskeleton, which would produce a flexible material that'd be 25 times stronger than steel.

    When even an Elon Musk Fanbouy like Real Engineering has to call it an "engineering shit show", you know Musk is on his last legs. Guess you can't fool all of the people all of the time Elon. You didn't start Tesla. You stole Martin Eberhard's company in a board room coup. Most of your (massively subsidized) cars have poor build quality. And your "prophetic pronouncements" are proving false. Your "hype a loop" is dead as is your little tunnel digger.

    stainless steel gets very brittle at the temps on the side not heated by sunlight in space .

      @BOOTYMONSTER there's a big but statement they left out. To transform fcc stainless to bct martensite (not bcc like the page claims) if needs to be deformed. Temperature alone will not transform it, the 3xx series austenitic stainless steels are well documented down to -423F.

      BOOTYMONSTER 3 days ago

      ".... cryogenic temperatures can cause a normally ductile and tough stainless steel, such as 301, 302, 304, 321, to partially transform to bcc structure, resulting in an impairment of ductility and toughness. ...."

    The melting point temperatures for ss are under compared to the upper atmospheres temps ...according to modern science so how do these materials handle not only the temps but the increase in temp by the friction etc . Everything played into the equation could someone please elaborate . Not a keyboard brave guy but someone from space x pls to end all the bs going around the web....

    • Lensflare Deviant

      The temps in the upper atmosphere are a non factor the air pressure is far to low.

  • Mike Gorgichuk
    Mike Gorgichuk 5 days ago

    Real engineering indicates that after 621 miles above the earth the temperature is 3600 degrees F and gets higher. Soooooooo you would need some kind of material that can stand that temperature. 304 stainless steel melts at 4442 degrees F. Stainless steel could sustain the temperature. I'm wondering if the lunar expedition vehicles were all made of stainless Steel? Hmmmmmmmm.

    • Lensflare Deviant
      Lensflare Deviant 3 days ago

      No. You're understanding of heat and temp is somewhat flawed. The temp is high but the pressure is low. Low pressure means very little conduction of that heat.

      Lensflare Deviant well some people are just a bit confused on materials terminology, others seem to willfully ignore facts, not sure what the case is here. I’m always surprised how many people who have no knowledge or experience in metallurgy seem to believe there’s a conspiracy against titanium just because it isn’t used in everything.

      Thomas Mahoney do you still think that the term “titanium stabilized stainless “ means it’s a titanium alloy and not a steel?

    • Aaron Washburn

      Thomas Mahoney I know titanium is not steel. The BAC-188 isn’t made out of titanium, it’s made out of stainless steel.

    • Thomas Mahoney

    Death trap. They need to approach it like the Italians did to conquer K2. They used an army supplying enormous infrastructure and support for the summit team. Harder than Everest. Likewise, they need a large revolving space station rotated around the earth with similar life support to earth such as gravity (rotation) and radiation insulation etc. It would carry a substantial crew. It would then build momentum over time in orbit before being released on a fast trajectory towards Mars to likewise become captured in it's orbit. From there attempts to land using shuttles would occur until a substantial base was built. The space station would be designed to return to earth by building a similar momentum in orbit before release towards earth and repeat the process indefinitely back and forth. So Space X can't do it on their own. Needs a global syndicate and a cheaper way to get mass into space. I'd recommend a gun barrel in the earth using propulsion from the base, not the craft to reduce fuel weight with an exit speed just under the speed of sound. Unmanned of course. This stuff could unite in orbit and plug together to form the station. Humans go later. Since the station would be radiation resistant anyway propulsion would be most likely nuclear. I think the Russians use it to propel their new unlimited range missile.

    I just realized that all worker unions are in trouble, AI is taking over, the big 5 corporations of the planet, want their AI products in all factories, warehouses and delivery vehilcles to replace humans and reduce the population only to people that are clients = 90% population reduction, they can reduce population by man slaughter (taking away your job = killing you, if everyone in a family of 2 to 10 lose their job in the next 2 years then that is murder), we are exactly at the time for EVERYBODY to strike against the governments and demand that human jobs cannot be replaced .... otherwise every job you can imagine from a farmer, banker, doctor, lawyer, driver to a scientist´s job can be replaced by machines. They don´t need humans to harvest food or raw materials and process them to the final product or service, which is delivered into your house ................

    I wonder if it is possible to extrude 301 stainless steel in a 9-meter diameter tube.
    Then the SpaceX workers would not have to do all that welding. (The best weld is no weld!)
    What are the technical challenges in this?
    So far, I am unable to find out the thickness needed.

    What was the Apollo capsule made of?.....It was made of an aluminum honeycomb sandwhich bonded between sheet aluminum alloy. The base of the CM consisted of a heat shield made of brazed stainless steel honeycomb filled with a phenolic epoxy resin as an ablative material and varied in thickness from 1.8 to 6.9 cm. And dont forget this capsual was supposed to keep out the massive solar radiation as well. Kind of goes against your take.

    How long is it going to take Elon Musk to figure out that NASA in the 1960s got it right with Lunar Obit Rendevous.and the LEM? And heck, the Moon landing didn't have to deal with an atmosphere to go through and more than twice the gravity on takeoff. Leave the bulk in orbit and only take down the surface stuff you intend to leave and the bit that you need to get back in orbit.This whole thing looks to me like a colossal, but unserious, effort. I suspect just like his Boring Tunnel (a totally silly concept) which was going to be using sleds and then abandoned them, Musk will come out with something different to hype later.

      You're talking different mission goals. At no point was re-use a factor in Apollo engineering. As it is this thing won't be able to land on the moon without some support infrastructure there so it'll more likely ferry things no further than lunar orbit.
