Wood doesn't burn or rot in the lifeless vacuum of space, but it will incinerate into a fine ash upon reentry into Earth's atmosphere — making it a surprisingly useful, biodegradable material for future satellites.

Don't metal ones burn up fine?

[-] themeatbridge@lemmy.world 38 points 10 months ago

No, actually. Metal doesn't burn up, it melts to slag and disintegrates, but the metal particles don't become gas the way carbon does. Then you just have a bunch of a space debris and reactive, aerosolized metal particles knocking around the upper atmostphere. Aluminum Oxide ash can float to the ground, or it can cause ozone decomposition. We're not entirely sure which is worse based on the amount coming back from satellites, but the number of satellites we're sending up is increasing rapidly. So it wouldn't hurt if they were a little less toxic.

For the most part, yes. The problem is pollution, like aluminum oxide.

Here is an article that explains better than I ever could: https://www.space.com/air-pollution-reentering-space-junk-detected

Sounds like a radical achievement if they pull it off.

Nobody else could say they built a wooden space machine and put it into orbit successfully

The dream of wooden pirate starships becomes reality!

[-] Batman@lemmy.world 5 points 10 months ago

I'm curious what kind of fasteners they use

[-] Zorque@kbin.social 11 points 10 months ago

Self-sealing stembolts.

[-] smuuthbrane@sh.itjust.works 6 points 10 months ago

Probably dowels, maybe some glue. Doubt they would use threaded fasteners for a demonstration like this.

[-] Batman@lemmy.world 4 points 10 months ago

Darn. Could have been big ammunition in the Phillips vs straighthead war.

[-] smuuthbrane@sh.itjust.works 4 points 10 months ago

Ugh, Robertson all the way.

Torx.

The only one actually engineered for its application.

[-] Kata1yst@kbin.social 0 points 10 months ago

Proprietary sacrilege. I ain't paying extra for a shape. Not to mention, which Torx? There are literally half a dozen varieties.

[-] Mac@mander.xyz 1 points 10 months ago

Source? I can only think of half a half a dozen.

[-] Kata1yst@kbin.social 2 points 10 months ago

You, me, and the wikipedia page agree then.

Awe, a little baby Borg cube! Are they going to put an AI on that?
