Japanese researchers just sent the world’s first wooden satellite to space, as reported by CNN. LignoSat, named after the Latin word for wood, was developed by Kyoto University and a company called Sumitomo Forestry.

The world's first wooden satellite, built by Japanese researchers, was launched into space on Tuesday, in an early test of using timber in lunar and Mars exploration.

The tiny satellite built by Japan will test the suitability of timber as a renewable material in space.
