The environmentally friendly LignaSat probe – set to orbit this summer – has been created to combat harmful aluminium particles
Japanese scientists have created one of the world’s most unusual spacecraft – a tiny satellite that is made of timber.
The LignoSat probe has been built of magnolia wood, which, in experiments carried out on the International Space Station (ISS), was found to be particularly stable and resistant to cracking. Now plans are being finalised for it to be launched on a US rocket this summer.
The timber satellite has been built by researchers at Kyoto University and the logging company Sumitomo Forestry in order to test the idea of using biodegradable materials such as wood to see if they can act as environmentally friendly alternatives to the metals from which all satellites are currently constructed.
They don’t last very long though, they are not particularly energy efficient, and they are single story.
It’s not like they have a superior manufacturing technique.
