Japanese researchers have developed the world’s first wooden satellite, which is set to launch in September on a SpaceX rocket.
This experimental satellite, called LignoSat, measures 10 centimeters on each side. It was created to help reduce the environmental impact caused by retired satellites.
Traditional satellites made of metal can leave harmful particles in the atmosphere when they burn up upon re-entry. In contrast, the wooden material used in LignoSat is expected to completely burn up, preventing these emissions.
LignoSat was developed through a collaboration between Kyoto University and Sumitomo Forestry. They chose wood because it offers a more environmentally friendly alternative to metal. The project aims to show that using wood in space can be both practical and beneficial for the environment.
Astronaut Takao Doi supports the idea of using non-metal materials for satellites. He believes that wooden satellites could become more common in the future. After LignoSat is launched, it will be sent to the International Space Station (ISS). There, scientists will collect data to see how well the wooden satellite holds up in space.
By studying LignoSat, researchers hope to learn more about the potential for wooden materials in space missions. They aim to understand how the wood handles the harsh conditions of space, such as extreme temperatures and radiation. This information could lead to more sustainable satellite designs and help reduce space debris.
