A highly regarded NASA astronaut since 1991, Pisces Susan Helms dispels many of the stereotypical images of her sign, which is traditionally accused of being unassertive—even wimpy—and afraid to take risks.

从1991年起，苏珊·赫尔姆斯就成为一名 NASA 的航天员，她打破了人们对于双鱼座固有传统形象的认识，人们很传统地认为双鱼座是一群没有担当的，甚至是怕事的，而且还害怕冒险的人。

Launching astronauts on a commercial vehicle would be unprecedented, but not far-fetched: NASA has already contracted SpaceX to take cargo to the ISS on unpiloted flights of its Falcon 9 and Dragon system, beginning in 2010, although SpaceX will need to carry out successful demonstration flights by then.

用商业飞船运送宇航员将是前无古人的，但并非不现实：NASA已经和SpaceX签订了一份合同，计划在2010年利用'猎鹰9'火箭和'龙'型飞船向国际空间站运送货物，前提是 SpaceX必须证明自己具备这种能力。

Professor Jorge Arenas of the Instituteof Acoustics in Valdivia, Chile,acknowledged that the problem was serious but said,"NASA has developedone of the safest and risk-controlled space programs in engineeringhistory."

智利瓦尔迪维亚声学院的教授乔治—阿瑞纳斯承认此问题十分严重，但是他说： NASA 已经创造出了工程学历史上最安全、风险控制得最好的太空计划之一。

Effort, mental demand, and performance are valuably the important results in the NASA Task Load Index assessment.

由NASA工作负荷量表评量结果反映出飞行员在此一操作阶段时，努力、心智需求、自我表现为重要的评量向度。

The idea would be that you could send data from France to Mars in a seamless way, says Adrian Hooke, a NASA scientist based in Washington, DC, who has been developing the protocol over the past decade with Vint Cerf of Google, a founding father of the internet, and others.

NASA华盛顿总部研究人员埃德里安·虎克和互联网之父、Google副总裁兼首席互联网顾问文顿·瑟夫及小组其他成员在这个协议上已经研究了十个年头了，虎克表示："意思就是你可以从法国向火星无缝发送数据"。

The electrokinetic model works well in an atmospherical medium, it is interesting to notice that some tests conducted in vacuum have demonstrated that it still remains a thrust in a micro-Newton to a milli-Newton range (this fact has been fully confirmed in some granted patents from the NASA and others companies).

动电学模型在空气媒质中表现很好，有趣的是在一些真空环境的测试中已经证明了仍然存在从微牛顿到毫牛顿级的推力（这个事实已经在一些由NASA和其他公司申请并被批准的专利中完全证实）。

Even though it's been nearly 40 years, this committee is still very busy making recommendations to NASA on the curation and distribution of all kinds of extraterrestrial samples to scientists all over the world.

时至今日已经将近40年了，该小组依然忙碌于向 NASA 提供所有类似的地外样品在掌管以及向全球的科学家分发方面的建议。

By 2015, to hear NASA tell it, a new manned spacecraft--the evocatively named Orion--will be carrying crews to Earth's orbit.

听听NASA的事，到2015年，一种新型载人飞船将会把人送到地球轨道。

Indeed, NASA's science budget is, he says, almost as big as that of the National Science Foundation, America's main funder of non-medical research.

的确，NASA的科研预算，他说，几乎和美国非医学研究的主要赞助人，美国科学基金一样多。

In the meantime, unknown to NASA, GE was developing its own design: a gearless, counter-rotating pusher system.

而在同一时期，GE也在进行着自己的开发设计（不知为何，NASA对此并不知情）：一个无减速器的反向旋转的推进系统。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
