    You only need a graphing calculator because you’re not allowed to use wolfram alpha, desmos, or Matlab. Since you’re mandated to use graphing calculators, (sometimes even specific models) there’s no incentive to make them cheaper or better since you need to buy them anyway.






  • Wood is interesting, but the article doesn’t address off gassing at all, which is a huge problem for communication satellites. Is there a way to keep the wood from off gassing? For 3d prints in vacuum, they metal coat them to keep the gas inside. Or maybe you could resin soak them? With hopefully an extremely UV stable resin. But I didn’t know what the weight trade looks like then, resin is heavy.

    But if you’re looking composites anyway, carbon fiber would be another great option. Lightweight but with a few manufacturing constraints. But should burn up to carbon dioxide on reentry.
