Many of us ponder what lies in\u00a0outer space<\/strong>. When we look up at the night sky, we see stars, the\u00a0twinkle<\/strong>\u00a0of a moving\u00a0satellite\u00a0<\/strong>and occasionally a distant planet. But one thing we don\u2019t see is the millions of pieces of\u00a0junk<\/strong>\u00a0filling up space. It\u2019s this\u00a0debris<\/strong>\u00a0that\u2019s causing problems for the existing technology that\u2019s up there and which we rely on.<\/p>\n

The amount of space junk is increasing. Over the last few decades, satellites and\u00a0rockets<\/strong>\u00a0have been\u00a0launched\u00a0<\/strong>into space,\u00a0littering<\/strong>\u00a0the<\/strong>\u00a0cosmos<\/strong>\u00a0as they go. It\u2019s estimated there are now millions of discarded pieces of metal and other materials in\u00a0orbit<\/strong>\u00a0\u2013 everything from old rocket\u00a0segments<\/strong>\u00a0to accidentally dropped\u00a0astronaut<\/strong>\u00a0tools, and even flecks of paint. The fear is that if we don\u2019t start taking this litter out of the sky soon, it will become a significant threat to active satellites. Nobu Okada, Chief Executive of Astroscale \u2013 a company working on ways to clean up space junk \u2013 says hitting \u201ceven a small paint fleck\u2026 has enough power to blow up other satellites.\u201d<\/p>\n\n

Read the rest of the article and write down your reflection<\/p>\n

Several ideas are being looked at to capturethe debris\u00a0floating<\/strong>\u00a0around in space. In 2018, the RemoveDebris\u00a0spacecraft<\/strong>\u00a0carried out various experiments, including testing a net that could\u00a0snare<\/strong>\u00a0a satellite and firing a harpoon at a target in orbit to try to catch it.<\/p>\n

This year the UK Space Agency is helping to fund new approaches to tracking satellites and debris in space. Jacob Geer from UKSA told the BBC: \u201cSpace surveillance and tracking<\/strong>\u00a0is one of the key things we can do to keep safe those satellites we rely on now, and to make sure certain orbits don\u2019t become inaccessible for future generations because there\u2019s too much debris in them.\u201d<\/p>\n

It\u2019s clear that a solution is needed so a\u00a0celestial<\/strong>\u00a0deep clean<\/strong>\u00a0can take place. But looking to the future, like any litter problem, we need to look at ways of creating less \u2013 and that shouldn\u2019t be the stuff of\u00a0science fiction<\/strong><\/p>\n\n\n\n\n\n\n\n\n\n
