研究近地小行星“龙宫”的日本探测器隼鸟2号向地球发回了最新数据，显示这一岩石天体所含有的水分远少于科学家的预期。隼鸟2号于2018年6月27日抵达龙宫附近。从那时起，隼鸟2号就开始对龙宫的表面进行调查，并放出多台探测机器人登陆小行星表面。▲隼鸟2号的可见光相机和近红外光谱仪观测证实，龙宫确实很缺少水分。2019年2月，日本宇宙航空研究开发机构（JAXA）完成了一次复杂的着陆操作，以采集龙宫表面的土壤样品，这些样品将在2020年晚些时候由返回舱带回地球。在对龙宫进行了将近一年的调查之后，隼鸟2号已经采集了许多宝贵的数据，将有助于科学家更深入了解太阳系的早期情况。“在收到首批数据之后才几个月，我们...
Study of near-earth asteroids "prince" of the Japanese probe hayabusa sent back to earth, 2, the latest data, display the rock bodies of water is far less than scientists had expected. Hayabusa 2 arrived on June 27, 2018, near the dragon palace. Since then, hayabusa 2 began investigating the surface of the dragon palace, and sent out more than one probe landed on the asteroid's surface. Bring hayabusa 2 of visible light and near infrared spectrometer observation confirmed camera, dragon temple is really a lack of moisture. In February 2019, the Japan aerospace exploration agency (JAXA) completed a complex operation, landing in dragon palace on the surface of the soil samples, these samples will be later in 2020 by the capsule to earth. In dragon palace after nearly a year of investigation, hayabusa 2 has collected a lot of valuable data, will help scientists to further understand the early situation of the solar system. "A few months after I received the first batch of data, we...
