First wooden satellite developed by Japan aims to reduce space debris

Wood has entered debased Earth orbit successful a signifier seldom seen before. In December 2024, 5 CubeSats were released from the International Space Station, including LignoSat, a tiny outer built mostly from magnolia timber.

The task is led by researchers astatine the Japan Aerospace Exploration Agency and Kyoto University, moving with Sumitomo Forestry. The purpose is applicable alternatively than symbolic. Engineers privation to recognize however wood behaves successful abstraction and whether it could assistance mitigate immoderate of the biology effects associated with accepted satellites. LignoSat remained successful orbit for 116 days aft deployment. According to the Nanosats Database, the ngo is planned for 2027. The experimentation sits wrong wider efforts to rethink outer materials.

NASA deployed Lignosat to trial wood successful orbit from the International Space Station

LignoSat is simply a CubeSat astir the size of a java mug. Its outer panels are made from honoki magnolia wood, selected aft earlier vulnerability tests connected the station. Three wood taxon were placed extracurricular to spot however they responded to vacuum, radiation and crisp somesthesia swings. Honoki showed the astir stability.The panels were assembled utilizing a accepted Japanese wood joinery method alternatively than screws oregon glue.

Researchers wanted to spot however untreated timber would grip accent without protective coatings. Inside the satellite, sensors recorded strain, interior somesthesia changes and radiation effects. There was besides involvement successful whether the geomagnetic tract would walk done the woody assemblage and disturb onboard electronics.

Space debris and outer reentry contamination gully concern

The biology statement is portion of the appeal. Most satellites are built from aluminium.

When they pain up connected reentry, they merchandise aluminium oxide particles into the precocious atmosphere. Scientists are inactive studying however agelong those particles stay and what effect they whitethorn have.Wood behaves differently. It is renewable and produces little metallic residue erstwhile it burns. Developers anticipation that biodegradable materials mightiness bounds semipermanent atmospheric accumulation arsenic outer launches proceed to increase.

LignoSat was deployed from the International Space Station with enactment from NASA. The ngo was small, but it signals a displacement successful reasoning astir spacecraft design.A 2nd mission, LignoSat 2, is expected successful 2027. Engineers volition reappraisal the archetypal acceptable of information earlier adjusting the design. For now, the outer has offered a humble trial case. Timber successful orbit, softly circling, giving numbers backmost to Earth.
