    Interesting, but i wonder what the point is? I would think that it would still need a metal container for shielding of the electronics. I guess we wouldn't have to worry too much about re-entry debris, at least from the covering. I just find it odd that they would use plywood, especially at today's prices!

      Well remember this is a 1U CubeSat, so it's only 4 inches on a side and hence 96 square inches of Baltic birch plywood.
      One of the objectives is to see how wood holds up in space and if there is any possibility of using it as a material in
      space. There will be a camera pointed back at Woodsat so they can observe what happens to it over time.


      "The mission of the satellite is to test the applicability of wooden materials, especially WISA-Birch plywood in spacecraft structures and expose it to extreme space conditions, such as heat, cold, vacuum and radiation, for an extended period of time."

        That is rather interesting.
        actually surprised it hasn't been tested before to see how wood products hold up.

        Perhaps in the vacuum of space I could get the finish on my projects without dust or runs.

          I too was surprised to hear that wood had never been tested in space before. Maybe the strength to weight ratio is too low so they never considered it in the beginning. But now that the cost of pushing junk into orbit has dropped dramatically it might be worth it. Thinking long term (very long) what if you could erect a biosphere on the Moon or Mars, then plant trees that would one day become raw material for so many useful products just as wood did here on Earth a couple centuries ago. And an added bonus is there capacity to process CO2 and generate some O2.

            Thinking along those lines you would truly need to have a very diverse variety of trees.

            When you look at how each species has it's own useful purpose, take the somewhat rare purple heart. with its density among other properties it's used in Hollands Dutch grain mills as the staves in the Wallower Wheel for power transmission. I believe the other gear is Elm or oak. with the two species in combination it greatly reduces vibrations within the windmill.

            Only reason I know that is because when I toured an authentic Dutch mill and seen all the purple heart pieces I couldn't imagine they would spend the money just to have the amazing purple wood up there.

            Here's a link to information about the windmill. looks like they used 16 species for specific tasks.
