Wondering if there are any studies about using wood as a material for insulation in spacecraft? My specific question is does anyone have any experience with it working as an insulator? I remember a specific type of hardwood (Jarrah) being used as a thermal insulator for large scale LNG tanks, but jarrah is super heavy. Are there any good examples of wood used in space?

We made a cubesat mockup out of wood recently, and it prompted all sorts of other ideas.

    $\begingroup$ Giving the benefit of the doubt that this isn't a spammy plea for survey votes, it needs to be edited to focus on a single question. There are at least 4 separate questions here. I have, accordingly, voted to close as "Needs more focus" until it is fixed up. $\endgroup$

    $\begingroup$ Lol, It can be both you know. But I guess the thing I'm most interested in, is the thermal properties. I've heard of specific hardwoods being used as insulators at an LNG facility, so I'm most interested in that. $\endgroup$

    $\begingroup$ In addition to being heavy, Jarrah though not rare, it is not an abundant timber. The trees only grow in the south west region of Western Australia & they can't be grown in plantations. They need to grow in a diversified forest. $\endgroup$
