In December, China lodged a formal complaint with the UN Office for Outer Space Affairs (UNOOSA), citing the same reason.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">In November, SpaceX Starlink internet satellites also dodged debris from Russia&#8217;s anti-satellite missile test to avoid in-orbit collisions.<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">Traditional communications satellites operate at an altitude of 35,786 kilometres in Geosynchronous Equatorial Orbit (GEO). But over the last few years, the Low-Earth-Orbit (LEO) satellites have taken over the skies, which operate at 500 kilometres to 2,000 kilometres above the Earth&#8217;s surface. LEO is becoming increasingly crowded due to increased satellites, raising the risk of collisions.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">The major contributor of space debris is nonfunctional spacecraft, abandoned launch vehicle stages, mission-related debris, explosions in orbit. Russia and its commonwealth allies currently have the most space junk circulating space, with the US, China, France and India following closely.<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">Increasing space debris may lead to <strong>Kessler Syndrome<\/strong>. Kessler Syndrome is a phenomenon where the space junk around Earth&#8217;s orbit will reach a point where more and more debris will collide with each other leading to more significant problems eventually making the Earth&#8217;s orbit challenging to use. It may pose issues for satellites, mission planners and astronauts, including disrupting critical functions such as communication, climate monitoring and remote sensing.<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\"><a href=\"https:\/\/polscienceweb.com\/index.php\/portfolio\/nasa-launches-james-webb-space-telescope\/\" target=\"_blank\" rel=\"noreferrer noopener\">NASA launches James Webb Space Telescope with a mission to unfold the universe<\/a><\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\"><a href=\"https:\/\/polscienceweb.com\/index.php\/portfolio\/james-webb-space-telescope\/\" target=\"_blank\" rel=\"noreferrer noopener\">James Webb Space Telescope \u2013 the successor of the Hubble Space Telescope<\/a><\/p>\n\n\n\n<\/details>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-text-align-center\">Source : <a href=\"https:\/\/www.bbc.com\/news\/business-59806499\" target=\"_blank\" rel=\"noreferrer noopener\">BBC<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Recent near-collisions of the Starlink satellite with China&#8217;s space station have prompted conversation of accumulation&hellip;<\/p>\n","protected":false},"author":1,"featured_media":6936,"comment_status":"closed","ping_status":"closed","template":"","portfolio-category":[427,429,426],"class_list":["post-6933","portfolio","type-portfolio","status-publish","has-post-thumbnail","hentry","portfolio-category-427","portfolio-category-december-2021","portfolio-category-newsfeed"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
