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.

A frozen landscape with breathtaking views, Greenland wants to attract more tourists, but its remote location and fragile environment -- which make it a unique destination -- also pose challenges.
"The effects of global heating are at their most pronounced in the Arctic," Michael Hall, a University of Canterbury professor and tourism expert, told AFP.
Global warming is accelerating "the loss of Arctic sea ice in summer, (as well as) the melting of permafrost, ice shelves and glaciers", he said, referring to elements that contribute to the island's uniqueness.
Across Greenland, locals are witnessing first-hand the effects of global warming.
On the southwestern coast, in Maniitsoq, the sea ice has not been solid enough to walk on since 2018. Residents have also seen it shrink from year to year, in addition to less abundant snowfalls.
Tourists are nonetheless awestruck by the vistas.
"It's terra incognita," said Amy Yankovic, a 55-year-old American tourist.
The Texan native traveled for almost 24 hours to get to Greenland, taking three connecting flights.
Tourism accounts for around eight percent of global greenhouse gas emissions, according to the United Nations, most of which is attributed to transportation.
There is "a kind of 'last-chance tourism', where visiting these endangered sites is about wanting to see them before they disappear", said Emmanuel Salim, a geography lecturer at the University of Toulouse in France.
He said similar destinations such as Churchill in Canada -- known as the "polar bear capital of the world" -- "have tried to position themselves as places for 'learning' about the environment".
But while such destinations can raise awareness about better environmental practices, their carbon footprints continue to rise, he lamented.
Developing tourism in a fragile environment is a tricky balancing act.
"Mitigation of the impacts of global heating on the Arctic is a global responsibility," said Hall, adding that "current mitigation attempts are greatly inadequate."
Greenlandic authorities insist they want a prudent development of the tourism sector, in order to create jobs.
"In recent years we've seen that young people have started to become tour operators," Maniitsoq mayor Gideon Lyberth told AFP.
"We're very, very happy, because young people have been leaving here for Nuuk, to live there, but now they're coming back," he said.
"Clearly such developments will usually be seen as a good idea, at least in the short term," Hall said.
