陨石可以提供关于早期太阳系是什么样的的线索,但是找到它们是相当困难的。现在,一些科学家正在转向无人机和机器学习,以更加高效地帮助发现新落地的陨石。主题语境:天文研究篇幅:354词建议用时:7分钟1 Meteorites(陨石)can offer clues to what the early solar system was like.But finding them is rather difficult.Now,some scientists are turning to drones(无人机)and machine learn-ing to help spot freshly fallen meteorites much more efficiently.“A team of six people on a meteorite-hunting expedition can search about 200,000 square meters per day,”says Seamus Anderson,a planetary scientist in Australia.
