For over fifty years, slowly at first, but with increasing intensity, we've been sending objects up into orbit. Most of these items begin life as useful 使節を開始する有用な devices, such as the thousands of satellites that bring us information and give 装置として us our 21st century communication, but even these eventually fall out of use 結仕 使われなくなる or break. These satellites, living or dead, share an increasingly crowded layer, 混雑した層 known as near-earth orbit, with rocket parts, tools, and pieces of metal from objects that have already crashed together and broken into pieces. 粉々になる ?? This garbage poses a threat both (to working" satellites of which there are thousands), and (to the earth itself.) For example, in 2009 a disused Russian 使われなくなった module crashed into an active US satellite) destroying both and forcing the International Space Station to change course to avoid the thousands of broken ためらう pieces. While most junk that falls back to earth burns up in the atmosphere. 大気圏上空で larger chunks can occasionally hit the ground, posing a threat to people and Pieces that do burn up] leave pollutants in the atmosphere, such as Property aluminum particles, which can destroy the ozone layer アルミニウム 粒子 It's clear that removing space junk is vital if we are to maintain and build upon our current satellite network. The problem has been discussed continuously since the 1970s, when Donald Kessler, a senior scientist at NASA 継続的に described a scenario (later known as Kessler syndrome) (where a runaway 制御不能の others more and more likely. While the 2009 incident may be the first large cycle of collisions begins, with each collision creating more debris, making 衝突のサイクル near-earth collision, it is thought that Kessler syndrome has already begun with smaller objects. Since Kessler syndrome was first described, many solutions have been proposed, from using lasers to robotic garbage collectors, but cost has been an obstacle to most. In 2021, a Japan-based company named Astroscale launched ELSA-d (short for "End-of-Life Services by Astroscale Demonstration") to show
