摘要
太空浩瀚无垠,但是地球周围的太空却越来越拥挤。由于新科技和相互竞争的宇航公司大量出现,导致进入近地轨道的成本更低廉了。但是太空中的物体越多,意味着使飞船受损的撞击事件可能也会越多。围绕地球的废弃垃圾层若不断增加,最终可能就没有空间来容纳未来有用的新卫星了。
Space is vast.But the area around our planet is getting crowded.New technologies and the proliferation of competing rocket companies have made it cheaper to reach 05 low Earth orbit.But more objects in space can also mean more spacecraft-damaging collisions.And surrounding Earth with a continually denser layer of outmoded junk means that eventually there wouldn't be room for the new,useful satellites of the future.
