NASA称，今日将由一大片太空垃圾进入国际空间站2英里范围之内，但是预计不会造成什么问题。

NASA says a large piece of space junk could pass within 2 miles at the station today , but notes it does not expect to be a problem .

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。

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 .

一份旨在限制未来这些碎片可能会对航空飞船造成的危险的报告在去年的四月份由宇航局发布，用来评估他们关于太空垃圾，名为MMOD（微流星体和太空碎片）的项目。

The report , Limiting future collision risk to spacecraft , was commissioned by Nasa last April to evaluate its programmes on'space junk ' , officially known as MMOD ( Micrometeoroids and Orbital Debris ) .

你在空间站亲眼眼看到过太空垃圾吗？

Have you ever seen some space junk with your own eyes ?

太空垃圾污染等等问题。

The problem of space pollution , etc.

美国宇航局工程师克里昂？莱维特表示，处理太空垃圾迫在眉睫。

Nasa engineer Creon Levit said it was imperative that something was done about space junk .

比起温室气体问题，太空垃圾问题应更容易达成共识。

It should be easier to reach an agreement on space junk than on greenhouse gases .

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

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。

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

目前还不知道该物体的目的是什么，不能排除民用目的：比如一个吸入太空垃圾的项目。

Its purpose is unknown , and could be civilian : a project to hoover up space junk , for example .

这块红色的物体被发现以及有几天的时间了，在最后被证实其实只是一块太空垃圾。

Red-faced astronomers only discovered it a few days before and until then they thought it was a piece of 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。

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

不幸的是，大多数的灯可以坚持的时间甚至还不如“好奇号”，最终它们都会被太空垃圾撞毁。

Unfortunately , most won 't even last as long as Curiosity ; eventually , they 'll succumb to space debris impacts .

但它给人一种一切都自然发生的感觉，给人一种超现实的自由感，和一种恐怖的随机感（太空垃圾风暴无端爆发）。

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

而最大的一起太空垃圾事件发生在2007年，当时中国军方炸掉了一颗卫星，只是为了展示中国有能力这么做。

The single largest space-junk incident was in 2007 , when the Chinese military blew up a satellite just to show that it could .

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

漂移的太空垃圾可能与太阳能帆板发生碰撞，帆板结构的动力学特性也是设计需要考虑的重要指标。

The drifting space junk may collides with the solar panels . The dynamics characteristic of the structure is an important indicator when spacecraft was designed .

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。

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

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。

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 .

目前，科学家们正在对近地轨道上的两万块太空垃圾进行检测，其中的绝大多数来自于碰撞的残骸或太空飞船的废弃物。

Some 20,000 pieces of rubbish are currently being monitored in low-Earth orbit , the majority of which are discarded bits of spacecraft or debris from collisions .

阻力变小会使太空垃圾积聚在轨道上，可能会与国际空间站或其他航天器相撞。

The lower drag can cause space junk to accumulate in orbit , which could result in a collision with the International Space Station or other spacecraft .

太空垃圾问题和气候变化问题类似：需要大家共担责任，面临的威胁大小难以预料，有许多“搭便车”的机会。

As with climate change , there 's a burden to be shared here , a threat of uncertain magnitude , and plenty of opportunity for free riding .
