    I would assume they just stick some Falcon9-diameter tanks in the hopper, they allready have the tooling.

    https://www.reddit.com/r/spacex/comments/a4eo12/first_grid_fin_has_been_removed_from_the_3x_flown/ Those gridfins look almost new although they were reused 3 times. Titanium would be a good candidate for a strong metall that can also resist high temperatures, but since Elon is talking about a "heavy" metal i can also imagine something nickel based, it could resist even higher temperatures. But even with the extremly low balistic coefficient of an almost empty starship i just cant imagine it reentering from interplanetary velocitys on just metall as a heatshield...

    Maybe they will go with a non-abaltive heatshield. Copying the shuttle would definetly be counterintuitive xD
  4. Everyone i know with decent age iphones complains about the lag and constant crashes. This includes an iphone 6 and SE, the 6 got unusable in the last months... Sadly the fairphone is extremly outdated in its hardware (it allready was at release), i like the concept. If you want good ROM support look at the XDA developer forums for devices you consider, its easy to check how much development is happening for the phone there...

    I doubt Elon will want to go with clustering again after the huge mess with the Falcon Heavy. Redesigning the core again for this task is propably as hard as building a new rocket, especially if you allready have tooling/engines for the large version. Maybe the will make the BFS land sideways somehow, that way they dont need the risky turn during reentry and have an easier way to disembark.
  6. That is the most shady computer part website ive ever seen. Also i wonder which DDR3 Ram doesnt work on Intel but AMD Systems?
  7. Thats perfectly possible with an APU. You can just install a better GPU later, also you can swap the CPU for something better if you want to (just have to add a GPU, too). AMDs current mainboards are supposed to work with their next generation processors till 2020...
  8. You will need to do some tinkering to use modern CPUs with Windows 7, so be prepared for that... Also Integrated Graphics arent as bad as they used to be, the AMD Ryzen 2400G is realy good for ultra tight budgets.

    Since they will require an extensive thermal management system anyway i dont see why SpaceX couldnt add a "refrigerator" or something to liquefy the boiloff...
  10. With a decent cooler an the right knowledge you can overclock the CPU quite a bit... A i7 3770 without k would be almost exaclty as fast as your current CPU, even for free it wouldnt realy justify the hassle to change the CPU.
  11. Why go with Intel? The i3 8100 costs about as much as an AMD R5 2600 (at least in germany, but i think those rising prices for Intel CPUs are the same everywhere) while offering less cores, less power per core, no hyperhreading, no overclockability, a worse stock cooler and less paths for upgrade. AMD said it would support AM4 till 2020 while Intels Socket 1151v2 has liekly seen its last generation of CPUs with the 9000 series...

    Harvester creator of KSP is back!

    To bad he doesnt do a KSP 2.0 (obviosly with another name). Modell airplanes are completly uninteressting for me, and limiting the game to VR will block out 99% of potential customers...

    Im sure someone allready measured this, but have no idea where to look. Are we sure the new Raptor engines on the BFS are sealevel engines? They seem a bit to big to fit 31 of them in the same diameter...

    SpaceX Discussion Thread

    Yeah, but they plan to lift off almost every time the land somewhere, so thats the case they have to worry about. Im sure they have thougt about it... BTW: I remember an article about ablation caused by material blasted away during the lunar landings. One mission landed close to a previos unmanned lander which was kinda sandblasted even by the small engine of the descent module. Landing one BFS on the moon wouldnt be much problem, but the second one would need a proper landing pad or a protective wall so it doesnt damage the first one.

    One thing i just thought about: Even the grasshopper version of the BFS will be a very powerfull rocket, to the point i cant realy imagine it taking off from just a flat surface without a launchpad. Reflected soundwaves could pose a huge threat, also even if it lands on solid concrete i imagine the landingpad wouldnt last long. This will be an even bigger problem on Mars...
