Freezing soil is a natural phenomina in cold and mountain areas, which has great impact on the regional climate, water cycle, and water balance. The land surface process in the condition of soil freezing and thawing is one of the most important process in the area. This paper firstly reviews the present study on land surface process in the condition of soil freezing and thawing, especially the development after the the hydrological land surface model introduced into the study of General Circulation Model, then introduces the undergoing international research project, such as Project for Intercomparison of Land-surface Parameterization Schemes and Cold Land Process Field Experiment by NASA, and finally analyses and puts forward the future research field and topics.

冻土是全球中高纬地区和高山地带普遍存在的自然现象，它对全球以及区域性气候、水循环、水平衡等都有着巨大的影响，土壤冻融条件下的陆面过程正是这种影响的重要环节，介绍了土壤冻融条件下陆面过程的研究现状，特别是在大气环流模型中引入水文陆面模型以来陆面过程研究的迅猛发展，对现在国际上正在进行的考虑冻土的陆面过程研究项目，如陆面过程参数化比较计划的第二阶段第五期PILPS (2E)以及美国NASA的寒区陆面过程实地试验计划也进行了介绍，并在此基础上对土壤冻融条件下陆面过程的发展趋势进行了分析。

But as Fermi project scientist Steve Ritz (NASA/Goddard Space Flight Center) notes, GRBs give us a chance to conduct the experiment in space by letting gamma rays run a very long race across the vast distances of intergalactic space.

不过根据费米望远镜项目科学家史蒂夫·里茨（美国航空航天局/戈达德宇宙飞行中心）的说法，伽马射线爆发提供了一个在太空进行实验的机会，因为伽马射线需要穿过广阔的星系空间，这是一段非常遥远的距离。

But NASA thinks it has an answer to the psychological challenge of interplanetary isolation.

不过， NASA 认为他们已经找到了治疗这种星际孤独的良方。

It is not only private companies that are suffering. In 2005 the European Space Agency concluded that ITAR made its co-operation with NASA's Mars rover "too complicated to be feasible" and that it had to become more autonomous.

受到干扰的不仅仅是私人公司。2005年欧洲太空署发现ITAR同NASA合作的火星计划以"可行性太低，复杂性太高"收尾，前者不得不变得更加自主。

NASA's principal investigator for the rover mission, Steve Squyres, and his colleagues report in the journal Science that the sedimentary rocks analyzed by Opportunity contain sulfate salts and a mineral called jarosite - harsh chemicals that are also found in briny water here on Earth.

此次漫游者任务的主要航天局调查员 Steve Squyres 和他的同伴在《科学日志》上发表道，"机遇号"分析的水成岩物质含有硫酸盐的成分以及一种叫做黄钾铁矾的矿物，这种化学物质具有很强刺激性，在地球的咸海水中也有这种物质。

That's Richard Gross, of NASA's Jet Propulsion Laboratory. He is the scientist who performed the calculations.

这位是NASA喷气推进实验室的理查德·格罗斯，是完成该计算的科学家。

He was part of a team of chemists at NASA's Jet Propulsion Laboratory in California, which was developing a device for preventing the contamination of spacecraft traveling on Mars and in outer space .

他是 nasa Jet 推进工程实验室中的一个化学专家小组中的一员，负责研发防止去火星的太空船以及外太空的废物污染的仪器。

Together with NASA's Jet Propulsion Lab, the company invented an infrared sensor that serves as the thermometer.

公司与NASA喷气推进器实验中心一起，开发了能够测量温度的红外传感器。

The impacts "sent towering mushroom-shaped fireballs of hot gas into the Jovian sky," according to NASA.

列维9号的彗星断裂成21个碎块撞击木星的情景，撞击产生的蘑菇形的火球在冲击到了木星的上空。
