Cheaper material isn't really an argument here. Common aluminium and titanium alloys are dirt cheap. Doubly so in aerospace context.

- direwolf20 9mo agoWood's even cheaper. Been to the hardware store recently? You're right though. I really doubt the cost of the aluminium is relevant to any satellite. It costs over 10k to launch the smallest cubesat.
- varjag 9mo agoYeah am not even sure prime quality mahogany (proposed here) is cheaper than aluminium at all.

There are some nice pics here: https://kitsat.fi/2022-04_one-year-after-making-our-project-public-now-ready-and-waiting https://kitsat.fi/2022-04_one-year-after-making-our-project-... Sadly, I don't think it was ever launched.
