The world's first wooden satellite has blasted off on a SpaceX rocket, its Japanese developers said Tuesday, part of a resupply mission to the International Space Station.
Scientists at Kyoto University expect the wooden material to burn up when the device re-enters the atmosphere -- potentially providing a way to avoid generating metal particles when a retired satellite returns to Earth, AFP reported.
These particles may negatively impact both the environment and telecommunications, the developers say.
Each side of the box-like experimental satellite, named LignoSat, measures just 10 centimeters (four inches).
It was launched on an unmanned rocket from NASA's Kennedy Space Center in Florida, Kyoto University's Human Spaceology Center said.
The satellite, installed in a special container prepared by the Japan Aerospace Exploration Agency, "flew into space safely", it said in a post on X.
A spokeswoman for LignoSat's co-developer Sumitomo Forestry told AFP the launch had been "successful".
It "will arrive at the ISS soon, and will be released to outer space about a month later" to test its strength and durability, she said.
Data will be sent from the satellite to researchers who can check for signs of strain and determine if the satellite can withstand extreme changes in temperature.
"Satellites that are not made of metal should become mainstream," Takao Doi, an astronaut and special professor at Kyoto University, said at a press conference earlier this year.

Paleontologists unveiled on Wednesday the fossil of a young marine crocodile dating back 10 to 12 million years that was discovered in a Peruvian desert.
The fossil of the gharial -- or fish-eating -- crocodile, around three meters long (nearly 10 feet), was discovered late 2023 in perfect condition in Peru's Ocucaje desert, around 350 kilometers (190 miles) south of the capital Lima, AFP said.
"This is the first time we found a juvenile of this species, that is to say, it had not reached its maximum size yet. It died before that," vertebrate paleontologist Mario Gamarra told a news conference.
The skull and jaws of these specimens differed from that of today's crocodiles and alligators, according to Gamarra, who headed the reconstruction of the fossil.
"They had an elongated snout and their diet was entirely piscivorous, feeding on fish," said Gamarra.
"The closest current relative to this crocodile would be the Indian gharial," he added.
The discovery was made jointly by Peru's Geological, Mining and Metallurgical Institute and the La Union school.
Peru's Ocucaje desert is rich in fossils, such as four-legged dwarf whales, dolphins, sharks and other species from the Miocene period -- between 5 and 23 million years ago -- that were previously discovered there.
