LignoSat is a small Japanese wooden satellite. It is credited as the world's first satellite to be made of wood.[1][2][3][4]

Background

LignoSat was developed by Kyoto University and logging firm Sumitomo Forestry as a demonstration of using wood for space exploration uses.[4]

The satellite is named after the Latin word for "wood" which is "Ligno". LignoSat is made of wood from honoki, a magnolia tree native in Japan. Wood from the tree is customarily used for sword sheaths. The choice of material was determined through a 10-month experiment aboard the International Space Station. The satellite was assembled through a traditional Japanese crafts technique without screws or glue.[4] It still has some traditional aluminium structures and electronic components.[3]

LignoSat 1

The LignoSat 1 is a CubeSat and measures 10 centimetres (3.9 in) on each side,[5] and weighs 900 grams (32 oz)[3]

The satellite was launched to space on November 5, 2024 by SpaceX's Falcon 9 Block 5 rocket inside the uncrewed Cargo Dragon from the Kennedy Space Center in Florida to the International Space Station.[6][7]

It was deployed into orbit from the ISS on 9 December 2024,[8] but it could not establish communication with ground station.[9] During the time in orbit the satellite stayed in one piece. [10]

LignoSat 2

LignoSat 2 is a 2U CubeSat. As of 2023, it is planned for launch in 2026.[11]
