This new spaceflight tech has a really retro really feel.
The world’s first picket satellite tv for pc, a tiny Japanese spacecraft known as LignoSat, arrived on the Worldwide House Station (ISS) as we speak (Nov. 5) aboard a SpaceX Dragon cargo capsule.
LignoSat measures simply 4 inches (10 centimeters) on both sides, however it may find yourself having a big effect on spaceflight and exploration down the street.
“Whereas a few of you may assume that wooden in house appears a little bit counterintuitive, researchers hope this investigation demonstrates {that a} picket satellite tv for pc might be extra sustainable and fewer polluting for the atmosphere than typical satellites,” Meghan Everett, the deputy chief scientist for NASA’s Worldwide House Station program, stated in a press briefing on Monday (Nov. 4), a couple of hours earlier than the Dragon capsule lifted off.
Typical satellites are made primarily of aluminum. After they deplete in Earth’s environment on the finish of their lives, they generate aluminum oxides, which might alter the planet’s thermal steadiness and injury its protecting ozone layer.

These impacts have gotten extra of a priority because the orbital inhabitants grows, due to the rise of megaconstellations like SpaceX’s ever-growing Starlink broadband community, which at the moment consists of about 6,500 energetic satellites.
Wood satellites like LignoSat — which substitutes magnolia wooden for aluminum — might be a part of the answer going ahead; they would not pump such damaging pollution into the environment after they fell again to Earth, mission crew members have stated.
“Steel satellites is likely to be banned sooner or later,” retired Japanese astronaut Takao Doi, an aerospace engineer who’s now a professor at Kyoto College, instructed Reuters. “If we are able to show our first picket satellite tv for pc works, we need to pitch it to Elon Musk’s SpaceX.”
LignoSat, which was developed by researchers at Kyoto College and the Tokyo-based logging firm Sumitomo Forestry, will quickly get an opportunity to show itself.
A few month from now, the cubesat will probably be deployed into orbit from the ISS’ Kibo module. If all goes in line with plan, its onboard electronics will document and beam dwelling key well being information for the following six months.
“Scholar researchers will measure the temperature and pressure of the picket construction and see the way it may change within the vacuum atmosphere of house, and the atomic oxygen and radiation situations as effectively,” Everett stated.
LignoSat crew members additionally say a profitable check may have implications far past Earth orbit.
“It might appear outdated, however wooden is definitely cutting-edge expertise as civilization heads to the moon and Mars,” Kenji Kariya, a supervisor on the Sumitomo Forestry Tsukuba Analysis Institute, instructed Reuters. “Enlargement to house may invigorate the timber business.”
