From today's BBC's Japan developing wooden satellites to cut space junk:
"We are very concerned with the fact that all the satellites which re-enter the Earth's atmosphere burn and create tiny alumina particles which will float in the upper atmosphere for many years," Takao Doi, a professor at Kyoto University and Japanese astronaut, told the BBC.
"Eventually it will affect the environment of the Earth."
"The next stage will be developing the engineering model of the satellite, then we will manufacture the flight model," Professor Doi added.
As an astronaut he visited the International Space Station in March 2008.
During this mission, he became the first person to throw a boomerang in space that had been specifically designed for use in microgravity.
Question: How does one throw a boomerang in space? Does it return? Will space boomerangs be standard issue for Space Force?
Reading about Takao Doi one sees quite a list of accomplishments, including discovering two supernovae in their spare time. For someone so versatile perhaps space-boomerang-throwing came easy.
