Messenger Flies Past Mercury in Preparation for Permanent Mission (1/2)



 大意
NASA has sent a new craft to research.


 听写
The Youngmenunmanned spacecraft was launched by NASA in August, 2004. Messenger which stands for Mercury surface basing space environment gear geochemistry and ranging, swooped prove than 199 kilometers of Mercury, the smallest planet in the universe that is also closest to the sun. Eric Finnegan is systems engineer for NASA’s Messenger mission. Finnegan says Messenger made a nightne-time-approach tort toward Mercury at nearly 26 thousand kilometers per hour. The planet’s gravitational pull slowed the spacecraft by 8 thousand kilometers per hour, for its eventual descent into orbit around Mercury in 2011. Finnegan says Messenger sent back preliminary photos of the approach, he says the spacecraft will begin beaming back more detailed imageryinmidry and data within the next day or two. “We were very very excited, we had a very successful flyby today, we still will be waiting for the next day or so to get down imageryinmedry but our mission initial indications flying by the planet using just their radio beeping beacon information now looks good.” Planetary scientists hope the 450-million-dollar mission will help them answer key questions about Mercury, a tiny planet with temperatures that swing between 315 degrees in the day time to minus 180 degrees at night.

这个无人宇宙飞船2004年8月由NASA发射。代表“空间环境，地质化学和范围”的“信使”下扑199千米到达水星。水星是宇宙中最小的行星，也是距离太阳最近的行星。EF是NASA信使任务的系统工程师。他说信使以每小时26000千米的速度在夜间靠近水星。行星的重力将飞船的速度降低为8000千米每小时，它将在2011年最终进入水星轨道。F说信使发回初步的照片，并将在未来一两天发回更加详细的照片和数据。“我们很激动，今天的飞行十分成功，我们还得等上一两天来获取图像。但我们绕行星通过电波信号获得的最初信息看起来不错。”行星学家希望这项斥资4亿5000万美元的任务能帮助他们解答水星的关键问题。这颗小行星的温度范围从白天的315度直到晚上的零下180度。


 总结
播音员语速很慢，却不明白她在讲什么……最近听力状态奇差，听了无数遍还是听的很烂……从ST烂到TIH……
