KYOTO, May 06 (News On Japan) –
A groundbreaking challenge to develop the world’s first synthetic satellite tv for pc product of wooden is underway in Kyoto, led by astronaut Takao Doi. The initiative is a part of a broader push towards environmentally sustainable area exploration.
In December two years in the past, researchers at Kyoto University started engaged on the satellite tv for pc, which measures about 10 centimeters on either side and weighs round one kilogram. Doi, who made historical past about 30 years in the past as the primary Japanese astronaut to carry out an extravehicular exercise in area, is main the challenge.
“The view of Earth from space is truly breathtaking,” stated Doi, who’s now a researcher at Kyoto University. “It leaves a deep impression.”
Doi turned more and more involved concerning the environmental affect of area improvement, notably the rise in aluminum oxide particles generated when typical steel satellites re-enter the Earth’s environment and deplete.
“As more satellites enter orbit, the amount of aluminum oxide left behind during re-entry also increases. This could contribute to abnormal weather patterns, which were previously unimaginable,” he stated.
Traditional satellites are usually constructed from metals equivalent to aluminum. When they full their missions and deplete upon re-entering the environment, oxidized aluminum particles can stay and accumulate, doubtlessly disturbing the local weather.
Doi turned to wooden as an answer. “Wood burns cleanly, turning into carbon dioxide and water vapor without leaving metal residue. A wooden satellite won’t pollute the atmosphere during re-entry, no matter how many are launched,” he defined.
Last 12 months, a rocket carrying the wood satellite tv for pc was launched. The improvement staff watched anxiously because it was launched into area alongside two different satellites. While the deployment was profitable, makes an attempt to ascertain communication the next morning failed.
“We’re not hearing anything… It’s out of sight. No good,” one staff member commented.
Despite greater than 200 makes an attempt, no response was obtained from the wood satellite tv for pc. Researchers imagine the problem might have been attributable to a failure within the exterior antenna deployment.
In response, the staff started engaged on a second model of the satellite tv for pc. Drawing on wooden’s capability to transmit radio waves, they redesigned the second mannequin with an inner antenna. The revised satellite tv for pc is scheduled for launch in fiscal 2027.
“If successful, wooden satellites could become a major step toward practical use, helping preserve the Earth’s environment,” stated Doi.
