World’s First Wooden Satellite Deployed In Space; NASA Ready To Test Its Durability

Published

on


The world’s first wooden satellite developed by Japan has been exposed to space. The Lignosat was deployed alongside four cubesats from the International Space Station (ISS) in December 2024 to test alternatives to conventional satellites.

It was developed by Kyoto University and Sumitomo Forestry after wood quality was tested in space.

The satellite was launched to the station by SpaceX in November last year as a step toward building environment friendly satellite and reduce space debris. It weighs about 900 grams and is made of 10 cm long honoki magnolia wood panels assembled with a Japanese wood-joinery method without the use of glues or screws.

In a blog published on Tuesday, NASA said that the satellite’s performance will be monitored by researchers.

“Researchers will use sensors to evaluate strain on the wood and measure its responses to temperature and radiation in space,” the agency stated. “Geomagnetic levels will also be monitored to determine whether the geomagnetic field can penetrate the body of the wooden satellite and interfere with its technological capabilities. Investigating uses for wood in space could lead to innovative solutions in the future.”

The deployment followed extensive experiments aboard the ISS that tested the durability of wood in space environment. Based on the results of the Exposure Experiment of Wooden Specimen to Outer Space, scientists settled on honoki magnolia wood.

The satellite will reportedly float in orbit for six months, enduring radiation and temperature swings from –65°C to 125°C. Traditional satellites are made using materials such as aluminium, titanium, teflon and thermoplastic which harm the atmosphere when they burn up after decommission.

Some of the materials just float in orbit in the form of debris, posing risk to satellites and the space station. Wooden satellites, experts, hope will solve these problems.

NASA Takes Instagram Followers By Surprise With Picture Of A Crane; ‘Is It Hacked?’

Published

By



NASA, on Thursday, surprised its Instagram followers by posting a picture of a Sandhill Crane. The image featured the crane looking dead straight into the camera with NASA‘s rocket assembling building visible as a blur in the background.

Deviating from the lines of astronomy, NASA chose to educate its followers about the bird which according to the agency is among the 1,500 species of animals and plants that reside at the Kennedy Space Center (KSC) in Florida.

The agency said that KSC, which shares space with the Merritt Island National Wildlife Refuge is a particularly favorable environment. The sandhill cranes get drawn to this region due to the region’s shallow freshwater habitats, which provide nesting space and a variety of food sources.

Also featuring in this picture is the Vehicle Assembly Building where NASA assembles its rockets including the Space Launch System (SLS) which launched Artemis 1 Moon mission in 2022.

The image shared by NASA took the followers by surprise who questioned ‘why the bird?’

“Has anyone hacked NASA’s page?” one user asked. “You’re a NASA page, why are you acting like the Nat Geo channel?” asked another.

Others just appreciated the bird staring into the camera with its big brown eyes and thanked NASA for the information.

U.S. satellites reveal China’s solar dominance

The sun‘s energy is plentiful. And China is capitalizing.

Images captured by two Earth-observing satellites, operated by the U.S. Geological Survey, revealed a rapid expansion of solar farms in a remote northern Chinese region, the Kubuqi Desert.

“The construction is part of China’s multiyear plan to build a ‘solar great wall’ designed to generate enough energy to power Beijing,” writes NASA‘s Earth Observatory. (For reference, although all this energy won’t directly power the Chinese capital, around 22 million people live in Beijing; that’s over two and a half times the population of New York City.)

The two Landsat satellite images below show a section of the major solar expansion between 2017 and 2024. Use the slider tool to reveal the changes. (For a size and scale reference, the images below are about 10 kilometers, or 6.2 miles, across.)

And the solar complex is still growing. It will be 250 miles long and 3 miles wide by 2030, according to NASA.

Though China’s energy mix is still dominated by fossil fuels — coal, oil, and gas comprised 87 percent of its energy supply as of 2022 — the nation clearly sees value in expanding renewable energy.

“As of June 2024, China led the world in operating solar farm capacity with 386,875 megawatts, representing about 51 percent of the global total, according to Global Energy Monitor’s Global Solar Power Tracker,” NASA explained. “The United States ranks second with 79,364 megawatts (11 percent), followed by India with 53,114 megawatts (7 percent).”

Energy experts say that solar energy, like wind, is an important part of an energy supply, as they’re renewable and have been shown to reduce energy costs. Fossil fuels, of course, still play a prominent role in most states’ energy mix today.

But the economics of solar are clearly there. The proof, via U.S. satellites, is in the Kubuqi Desert.
