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



 大意
The scientist makes some instruction of the planet.


 听写
Astronomers say the planet is heavily cratered and has a large iron core. Louis Friedman has heads the Planetary Society. “Mercury is very ironablereally an oddball, it’s very dense, so our solar system object, it is very small. It indorses is in toward the sun. It’s only about the size of the Earth’s moon, a little larger, and as such it harder thehow did it form and however the it formed is gonna tell us something about the whole processprices of planet formation.” Friedman says the Milky Way is like a jigsaw puzzle. He says only when all the pieces are in place, and all the planets are explored, will the astronomers understand how the galaxy was formed. “Mercury’s very very dense and it’s a very heavy object, and therefore getting a really good handle on that density and its mass and associated side size will help us in trying to determine what happened at the time of planetary formation, how did they it reach that sizes and how did they it involve evolve and soon match muchabout its final orbits.” Messenger is about halfway through its journey to put it in mpermanent orbit around Mercury in 2011. But until then, there will be another flyby this October and again in September 2009.


 生词
cratered 形成火山口的。


 翻译
天文学家说这个行星上有很多火山口,有一个大的铁核。行星社团的负责人LF说:“水星是一个非常古怪的行星,密度很大,绕日运行。他比月亮稍微大一点,他如何形成将告诉我们行星形成的全部过程。”F说银河像一个拼图,只有每一片都在正确的地方,每一个行星都探索过,科学家才能明白星系是怎样形成的。“水星的密度非常大,它很重,所以研究好它的密度、质量和相关大小将帮助我们确定行星形成的过程,它们如何达到这样的大小,怎么发展,它的轨道如何。”信使的环水星行程已经完成了一半,它将在2011年进入水星临时轨道。在此之前,今年10月和明年9月还会有其他的飞船发射。


 总结
这位科学家的浆液性卡他啊……
