The World’s First Wooden Satellite in Space
sustainable: a way of using resources that does not harm the environment and can be continued for a long time
Imagine a satellite made not of metal but of wood. This is what NASA and Japan’s space agency, JAXA, are planning. The satellite, small enough to fit in your hand, is made from magnolia wood. Why wood, you might ask? It won’t add to space junk. Once the mission is done, the satellites burn up when they return to Earth, leaving no waste.
There are thousands of old satellites and space debris circling the Earth. This debris is a threat to other spacecraft and to people on Earth. It also adds to light pollution, making it harder to observe space from Earth. If this project succeeds, satellites could become more sustainable.
