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.

Three Chinese astronauts returned to Earth on Monday after a six-month stay on the Tiangong space station, part of China’s effort to be a global leader in space exploration.

A parachute slowed their capsule's nighttime descent to a remote landing area in China's Inner Mongolia region. The crew emerged after touching down at 1:24 a.m. A Chinese national flag stuck in the ground near the capsule flapped in the wind.

In recent years, the country's space program has brought back rocks from the moon and landed a rover on Mars. It aims to put a person on the moon by 2030, which would make China the second nation after the United States to do so.

The space station astronauts returned after welcoming a replacement three-person crew last week for the latest six-month mission. The new team of one woman and two men will conduct experiments, carry out spacewalks and install equipment to protect the station from space debris.

A space agency official said in April that Tiangong had maneuvered several times to avoid debris and had partially lost power when the solar wing's power cables were hit by debris, according to a report from the official Xinhua News Agency.

China is among the countries that have created space debris, including the reported break-up of a rocket stage in August during the launch of the first 18 satellites for a global internet service similar to Starlink, the still-growing constellation of satellites operated by Elon Musk's SpaceX.

Tiangong, which means Heavenly Palace, was completed two years ago and orbits the earth.

Only Chinese astronauts have gone to the space station so far, but a space agency spokesperson said last week that China is in discussions to select and train astronauts from other nations to join the missions, Xinhua reported.

Astronauts from several nations have traveled to the International Space Station, but China is blocked from that program mainly because of US concerns over the military's involvement in China's space program.

China laid out an ambitious plan last month to become a leader in space science research by 2050 in conjunction with its advances in space exploration.
