That was an excellent read for explaining why space isn’t just hard, but expensive.
I enjoyed reading this! But on one thing
> You and I will probably die before we’re allowed to take a bottle of water through airport security again
We could again bring water through airport security for some time in e.g. Rome's FCO (2 years maybe? It's been a while)
Good read.
"Since that time, I’ve learned that small heaters (like coffee makers or kettles) can be kryptonite to an inverter, and that this is common folk knowledge among solar installers."
Is there any more on this? It can understand inductive loads maybe challenging inverters but resistive loads should be easy? Is it an issue of cheap inverter design, or something more fundamental?
Why this ISSpresso machine was developed and sent into orbit at all? What scientific outcome does it have? Why was it necessary spending taxpayer's money developing it?
The Pressurized Payloads Interface Requirements doc is kind of interesting. Lots of diagrams & such that would be great for art projects.

The flow diagram provided for fracture control is incredible. Quite a work of art. [1]

Update: After staring at this flow diagram for quite some time, I realize it's actually the most robust, "complete-seeming" finite state machine I have seen used in the real world.
