"A made-in-Japan solution for space junk that goes against the grain."

Against the grain, get it? They're talking about wood.

"Wooden satellites would mitigate the increase of metal in the stratosphere and the risks from tumbling satellites at a time when the atmosphere is growing ever more crowded thanks to SpaceX's launches of thousands of satellites and the expansion of its competitors such as Amazon."

"Back in 2022, Kyoto scientists sent wooden samples -- cherry, birch and magnolia -- into space. Magnolia, which is a hardwood, is relatively light and has dimensional stability that is superior to other species, Koji Murata, a Kyoto University professor who specializes in wooden materials and agriculture, says, making it a winning candidate for the project."

Finally some action on #spacejunk

The NPRM ... lays out five upper stage disposal options including conducting a controlled reentry, moving it to a less congested storage or graveyard orbit, sending it on an Earth-escape orbit, retrieving it within five years and performing an uncontrolled atmospheric disposal or natural decay within 25 years. The FAA noted that the proposed rule would “align commercial space orbital debris mitigation practices with those accepted by the U.S. government for its space missions.” The rule will be open for public comment for 90 days following its publication in the Federal Register.
