Yet there's a sense of everything happening spontaneously, of surreal freedom plus a fearful randomness that unleashes those debris storms.

It will always be cheaper and easier to prevent debris rather than remove it after the fact.

防止太空垃圾产生总是比产生之后清除成本要低，也更容易。

For example, when a U.S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

例如,2009年,一颗美国卫星撞上一枚老旧的俄罗斯火箭时,它裂成了2000多块碎片,增加了太空垃圾的数量。

It is the solar maximum period so some solar activity can be expected, and they have already laid the groundwork for their space junk claims.

现在是太阳活动峰期所以可以预期某些太阳活动，而且他们已经为太空垃圾的声明打好了底子。

To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most.

为了减少额外的太空垃圾，各国同意所有新的太空工具最多只能在太空停留25年。

NASA says it believes a large piece of space junk is not going to be any threat to the astronauts in space.The rocket debris is expected to pass within 2 miles of the Shuttle Discovery and international space station tomorrow.

NASA称，大片的太空垃圾不会对太空中的宇航员造成威胁。明天，预期该火箭残骸将进入发现号航天飞机和国际空间站两英里之内。

Many scientists also suggesting different ways to clean up space junk.

许多科学家还提出了清理太空垃圾的不同方法。

Nudging would also be more accurate and it is thought the process could divert up to half of all space junk.

运用激光具有准确性高的特点，据预计，这样的方法可以清扫掉近一半的太空垃圾。

Nasa is considering using lasers to deflect space junk around Earth and stop it colliding with satellites.

美国宇航局NASA目前正在打算利用激光给环绕在地球周围的太空垃圾来一次大扫除，目的是为了防止他们与卫星发生碰撞。

Lasers similar to those used for welding in car factories would be fired through telescopes to 'nudge' piles of rubbish left in orbit.

这种激光的应用类似于汽车厂里的焊接技术，而这种激光将会通过望远镜来发射并推开轨道上遗留的太空垃圾。

In England scientists are testing a metal net that can be fired into space junk.

在英国,科学家正在测试一种可以发射到太空垃圾中的金属网。

The gentle movement would stop them from taking out communications satellites or hitting the International Space Station.

这样的一个动作这将有效的预防太空垃圾与通讯卫星或者国际空间站发生撞击。

The theory marks a change in approach from previous research which looked into using expensive military Star Wars-style lasers to destroy space junk.

利用军用的类似于星球大战的激光来清理太空垃圾，这样的一个理论与之前的研究有很大的区别。

The environment of the assessment of the prominent monument was permanently commented.

杰出的纪念馆的评估环境被永远地评论了.

The museum has a collection of Du Fu's poems and paintings.

纪念馆收藏了杜甫诗作和绘画作品.

We now state the idea of the previous paragraph as a theorem.

现在我们把上一段的概念叙述成定理.

It is misleading to refer to the principle as an " energy theorem ".

将功的定理称为 “ 能量定理 ” 是会使人误解的.

The normal mesangium contains about 2 to 4 mesangial cells, a macrophage-like function.

正常系膜含2～4个具有巨噬细胞的功能的系膜细胞.

It iswonder that a few years after the fall of the Yangtze River Delta!

难怪这几年落在了长三角后面了!

Join the Changjiang delta with the Zhujiang River Delta and progress together with them.

力争上接长三角,下联珠三角,共同发展进步.

Layout of environmental incorporation in the region of Changjiang deltais imperative under the situation currently.

摘要当前,长三角生态环境一体化规划势在必行.
