      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.

    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.

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.

    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.

    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.

    The moronic way of doing things we have and do today, wasting 95% of a material, the reason is expensive, you could put into modular molds and assemble together, to maximize material and fabrication time/process and make the rockets reusable. Also Rockets are not only great polluters, but highly inefficient from the load to space POV, a better way is with a SABRE engine aircraft, similar for other planets. Also we could use the H-bomb mechanism in small and controlled way to make nuclear power to work positively for us, immense power, small material. Also discarded rocket/spacecraft stages should be responsibility of the entity that launches it to recover them on an orbital dumpster or direct them to a specific location for reuse/recycling

    That isogrid structure has a problem I see. It's diagonally positioned. Further resistance to buckling would be achieved if it lined up straight. Test this one yourself, make two tubes of cloth(same size) but one with the weave diagonal and the other straight, then fill each with a long balloon keeping the pressure of each the same. Now try to buckle each. The one with diagonal weave will be substantially weaker.
    Curiously I found this in an article describing why penile erections can be so stiff. (The tissue fibers run straight both around the circumference (one layer) and lengthwise another layer)

    I can pour a half inch thick steel bar
    And can pull a muscle trying too bend it
