早在远古时候,人们就开始关注太空中各种各样的神秘现象。浩瀚的宇宙不仅带给人们许多美好的想象,也让人们更加积极地探索太空。随着科技的飞速发展,人类把火箭、卫星、飞船接二连三地送出地球,可是也将形形色色的垃圾留在了太空中。为了解决这个问题,科学家制造了许多“太空清洁工”,利用它们来“打扫”太空。 As early as in ancient times, people began to pay attention to various mysterious phenomena in space. The vast universe not only brings people many beautiful imaginations, but also allows people to explore space more actively. With the rapid development of science and technology, humans have sent rockets, satellites, and spacecraft out of the earth one after another, but they have also left all sorts of garbage in space. To solve this problem, scientists created many “space cleaners” to use them to “clean” space.
