TOKYO, May 29, 2024 (BSS/AFP) - The world's first wooden satellite has been
built by Japanese researchers who said their tiny cuboid craft will be
blasted off on a SpaceX rocket in September.

Each side of the experimental satellite developed by scientists at Kyoto
University and logging company Sumitomo Forestry measures just 10 centimetres
(four inches).

The creators expect the wooden material will burn up completely when the
device re-enters the atmosphere -- potentially providing a way to avoid the
generation of metal particles when a retired satellite returns to Earth.

These metal particles could have a negative impact on the environment and
telecommunications, the developers said as they announced the satellite's
completion on Tuesday.

"Satellites that are not made of metal should become mainstream," Takao Doi,
an astronaut and special professor at Kyoto University, told a press
conference.

The developers plan to hand the satellite, made from magnolia wood and named
LignoSat, to space agency JAXA next week.

It will be sent into space on a SpaceX rocket from the Kennedy Space Center
in September, bound for the International Space Station (ISS), they said.

From there, the satellite will be released from the Japanese ISS experiment
module to test its strength and durability.

"Data will be sent from the satellite to researchers who can check for signs
of strain and whether the satellite can withstand huge changes in
temperature," a Sumitomo Forestry spokeswoman told AFP on Wednesday.

Also on Tuesday, a rocket carrying a separate sophisticated satellite -- a
collaboration between the European Space Agency (ESA) and JAXA -- blasted off
from California on a mission to investigate what role clouds could play in
the fight against climate change.

The EarthCARE satellite will orbit nearly 400 kilometres (250 miles) above
Earth for three years.
