When we think of space satellites, we tend to think of bulky and polluting metal machines, but the situation could change. Researchers from Kyoto University have developed the first wooden satellite to orbit the Earth, aiming to combine solidity and respect for the environment.
Stronger than it seems
Called LignoSat, this wooden satellite weighs 900 grams and is the size of a palm. Designed by researchers at Kyoto University and real estate builder Sumitomo, LignoSat sits in orbit about 400 km above Earth, reports Reuters. Koji Murata, professor of forestry sciences at Kyoto University, explains that the choice of wood is not trivial, it is more sustainable in space than on Earth, because there is no water or oxygen which could rot or ignite it. At the end of its life, when the satellite must fall back to Earth to burn, it would also produce fewer toxic compounds.
For six months, the electronic components on board the satellite will have to measure how the wood resists the extreme environment of space with temperatures oscillating between -100 and 100°C every 45 minutes and alternating between darkness and light. sun. If the tests prove conclusive, the researchers hope to be able to propose a wooden satellite model that would be certified by NASA, proving that wood can be a feasible space material.

An environmental challenge
Space is far from being the empty space we imagine: many space debris resulting from previous missions float around the earth and scientists are alerted to the threat that this debris can represent when it will fall and burn on Earth.
Interviewed by the BBC, Dr Simeon Barber, a space researcher at the Open University in the UK, said he was skeptical that wooden ships could provide the complete answer to space pollution. If he specifies that “materials like wood that can burn more easily would certainly reduce these metal contaminants” he warns that manufacturers could choose to take more equipment and create another type of pollution.

Wooden Satellites: The Next Big Thing in Space?
So, researchers at Kyoto University have decided that regular satellites are too… well, metallic? Yes, you heard it right! Introducing the latest in space innovation: a wooden satellite orbiting Earth. Because when you think of high-tech, cutting-edge science fiction, obviously, you think about trees, right? It’s like they’ve taken “going green” to a whole new level — next stop, a wooden space station! Maybe they can hang some bird feeders out there too!
Stronger than it Seems!
Meet LignoSat, the wooden wonder weighing in at 900 grams—that’s just about the weight of a medium-sized cat! Imagine a cat, but instead of sleeping on your keyboard, it’s measuring temperature changes 400 kilometers above the Earth… and it doesn’t even need to be fed. Built with an environmentally friendly twist, this satellite is aiming to blend strength with sustainability, which is a much-needed upgrade from the “bulky and polluting metal machines” we usually associate with space.
Professor Koji Murata explains that wood is not just for furniture or constructing treehouses anymore. It’s ready for the stress of space, potentially enduring extremes of -100 to 100°C every 45 minutes—all without breaking a sweat. It’s like asking your Scotch pine to hit up the North Pole and the Sahara in the same day! And when it breaks down? No toxic compounds—yay for no more unwanted astronaut allergies!
An Environmental Challenge
Now, let’s talk about space pollution. Contrary to popular belief, space isn’t just a glamorous void; it’s full of debris—like an untidy closet, but instead of shoes and old magazines, it’s bits of metal from past missions. And we thought our planetary issues were bad! Dr. Simeon Barber from the Open University is skeptical about whether our dear LignoSat will save the day. He hints that while wood may reduce metal contaminants, it could also lead to new forms of pollution. It’s a bit like trying to solve your fridge’s mold problem by just stocking it with pizza. Seems clever until you remember the pizza leftovers!
So, can we finally rest our heads easy knowing that wooden satellites will solve space pollution? Or should we keep our Earthly concerns in orbit? With six months of testing on the wood’s endurance ahead, expect a mix of results, excitement, and possibly some very crispy satellite pieces falling back to Earth! Fingers crossed!
In conclusion, as we get ready to launch this wooden marvel into the stars, let’s keep eye on those eco-friendly goals. Because who knows? It might not be long before we’re building *spaceships* out of driftwood and sending picnics to Mars — and is there anything more sensible than enjoying a BBQ on the Red Planet?

Traditionally, space satellites conjure images of large, metal structures associated with pollution and waste. However, scientists at Kyoto University have revolutionized this perception by creating LignoSat, the world’s first wooden satellite, which aims to harmonize durability with environmental stewardship.
Stronger than it seems
Named LignoSat, this innovative satellite weighs 900 grams and has a compact size comparable to that of a human palm. In collaboration with real estate giant Sumitomo, researchers designed this satellite to operate at an altitude of approximately 400 kilometers above the Earth’s surface, according to a report from Reuters. Koji Murata, a professor specializing in forestry sciences at Kyoto University, emphasizes that the selection of wood as the primary material is significant; it proves more resilient in the harsh conditions of space compared to Earth, where factors like water and oxygen would lead to decay and combustion. Furthermore, when LignoSat completes its mission and re-enters the atmosphere to incinerate, it is expected to emit significantly fewer toxic substances.
For an extensive period of six months, the satellite’s onboard electronic components will rigorously test the wood’s durability against the intense and fluctuating conditions of space, experiencing extremes of temperature that range from -100 to 100°C every 45 minutes while subjected to cycles of darkness and sunlight. Should the experimental results be promising, the research team aspires to produce a wooden satellite variant that could secure NASA certification, thereby validating wood as a viable material for future space applications.
An environmental challenge
Space is not the desolate expanse it often appears to be; it is riddled with an alarming amount of space debris from past missions that poses a potential threat when re-entering the Earth’s atmosphere. This debris raises concerns among scientists regarding the environmental risks associated with its eventual disposal.
Expressing his skepticism, Dr. Simeon Barber, a prominent space researcher at the Open University in the UK, cautions that while the introduction of wooden satellites may alleviate some aspects of space pollution, it does not offer a comprehensive solution. He remarks that “materials like wood that can burn more easily would certainly reduce these metal contaminants,” yet he warns that manufacturers could opt to deploy additional equipment, potentially leading to a new form of pollution.

To release fewer toxic compounds than conventional satellites made of metal or plastic.
The team is particularly interested in understanding how wood can withstand the extreme temperature fluctuations in space, which can swing from -100°C to 100°C every 45 minutes, along with the cyclical exposure to sunlight and darkness. The six-month mission aims to test the satellite’s performance under these conditions, assessing its structural integrity and any potential degradation of the wood.
While this design presents a novel approach to satellite construction, experts are cautious about overestimating the potential of a wooden satellite to address space pollution. Dr. Simeon Barber, a space researcher at the Open University, points out that while burning wood could lead to a reduction in metal debris upon re-entry, there’s a risk that manufacturers might compensate for the use of wood with more equipment, leading to different forms of pollution.
Despite the skepticism, the project marks an important step toward integrating sustainability into space technology. If LignoSat’s tests are successful, it could pave the way for the use of more eco-friendly materials in future satellites, contributing to a greener approach to space exploration. Ultimately, this initiative could spur greater discussions on how to balance advancements in technology with environmental responsibility, fostering innovation that carefully considers its impact on both Earth and outer space.
As we look forward to the results of LignoSat’s mission, the intersection of cutting-edge technology and environmental stewardship continues to take shape, reminding us that sometimes even the most traditional materials can have a place in our futuristic aspirations—perhaps one day, we could indeed see wooden space stations, turning imagination into reality.
