Have you ever worried about debris from falling rocket hitting you on head? That scenario has never been high on list of life's worries. chances of piece of space junk hitting us were almost zero. However, that is changing. Scientists say there is growing likelihood that rocket parts falling back to Earth could hit and kill someone in next ten years. This is because more countries are sending more rockets into space. Scientists say space is becoming congested. They are calling on nations and companies that send rockets into space to be more responsible. They want them to control reentry of any rocket parts floating in lower atmosphere.

Scientists in Canada did research on number of rockets launched into space, and risk of people being hit by falling debris. There were 133 rocket launches in 2021. That was record. It looks like that record will be broken this year. scientists said more than 60 per cent of rockets are abandoned in space after they release their satellites. abandoned spacecraft can circle the earth for years before they fall back down. key finding of the research is that rocket parts are more likely to hit somewhere (or someone) in Global South. However, most rockets are launched from Global North. The scientists say countries and companies are "exporting risk to rest of the world".
