This chart tells you why we wont be getting critical minerals like lithium or rare earths from space. You're not brining back 100s of thousands of tons and if you tried you'd fill the atmosphere with nitrous oxides from reentry. Space resources are for space.

While not particularly well written, this new paper introduces architectural forms that minimize tensile stresses for structures built in-situ on Mars. Neat idea. nature.com/articles/s4159…
