Man achieves its first landing on comet

导读:历时10年之久，欧航局的“菲莱”号着陆器成功着陆彗星，这也是人类历史上首次成功着陆彗星。据悉，该举将有助于进一步探究太阳系甚至人类的起源。

Man achieves its first landing on comet

十年一剑 人类探测器首次成功登陆彗星

Reported from foreign media, European Space Agency (ESA) confirmed the news that the lander, Philae has successfully landed on the surface of a Jupiter comet shorten as 67P, setting a new milestone in the history of man’s exploration into the space. This is the first successful landing on comet in history, which has much significance in the research and exploration of comets.

据外媒报道，欧洲航天局收到确认消息“菲莱”号着陆器成功着陆木星彗星67P表面，完成了航天探索中里程碑式的一步。这是历史上第一次成功着陆彗星，对针对彗星的研究和探索有着非常重要的意义。

The Philae lander is reported has flown in its probe Rosetta for over 10 years, covering up to 6.5 billion miles just to make this successful landing. Launched in March of 2004, Rosetta searched for 10 years before it finally caught the 67P comet which is coming towards the sun in the space 0.4 billion miles away from the earth in August of 2014.

据悉，“菲莱”号着陆器在此次成功着陆之前，已乘坐“罗塞塔”探测器飞行了十年有余，旅程长达65亿公里。“罗塞塔”彗星探测器于2004年3月升空，历经10年终于在2014年8月，在距离地球4亿公里的太空追上正不断逼近太阳的彗星67P。

Rosetta released Philae in 9:35 on 12th, European central time. Philae, weighting 100 kilos with 10 equipped scientific instruments, with the size of a refrigerator, approached the comet with a walking speed of 3.5 miles per hour, which takes nearly 7 hours to finally land on the core of the comet. As the small gravitation of comet, the landing of Philae needs bolts to fix its position.

据悉，“罗塞塔”于欧洲中部时间12日9时35分释放“菲莱”着陆器。“菲莱”重100公斤，大小如同一个电冰箱，携带了10个科学仪器。它以每小时3.5公里、几乎等同于步行的速度向彗星靠近，耗时7个小时才能抵达彗核。由于彗星引力小，“菲莱”着陆需要用螺栓固定。

This project involves the research and efforts of over 2000 employees and companies or factories from 14 different countries for nearly 20 years, with investments of up to 1.4 billion euros from European countries.

该项目得到欧洲各国共14亿欧元的投入，涉及2000多名员工前后近20年的研发与心血，还有来自14个不同国家的公司或工厂的参与。

Astronomers believe that comet, consisting of matters of initial solar system, is likely to maintain its elements intact due to its low temperature and the frozen surroundings. Research of comets would help reveal the many mysteries concerning the forming of solar system. Scientists hope that this landing would help understand comets formed in the initial period of solar system and further explores the origin of solar system or even of human being.

天文学家认为，彗星由太阳系诞生初期的物质组成，由于它们自身温度极低并置身于“天寒地冻”的宇宙空间，其成分几乎不变，对它们进行研究将有助于揭开太阳系形成的诸多奥秘。科学家希望借此了解形成于太阳系形成初期的彗星，进一步探究太阳系甚至人类的起源。
