The orbital characteristic of interplanetary probes has a direct bearing on the aim of probing. To explore the polar cap of the object body requires polar orbit(or the high inclination orbit).

星际探测器轨道的特征与探测目的密切相关，对目标天体两极地区进行探测显然采用的是极轨道（或接近极轨道）。

Earth will become a desert planet, with at most a shrunken polar cap and only traces of precious liquid.

So to maintain the topography of the south polar cap, there has to be water ice in there stiffening it up.

所以要想维持南部冰冠的地形，就必须有冰水使其变得坚固。

Still, this sharp view of Mars recorded on January 22nd is an example of the telescopic images possible in the coming days. The planet's whitish north polar cap is at the upper right.

然而，这张锐利的望远镜影像拍摄于1月22日，可想像未来几天的火星模样，其北极冠的白色特征就在右上方。

At night the electron density is very low when the station situates at the polar cap area.

夜间进入极差区后，电子密度则很低。

Melting of the polar ice cap is a global concern because it has the potential to alter the geopolitical balance in the Arctic heretofore frozen in time.

北极冰帽融化正引起全世界的关注，它有可能改变该地区的地缘政治平衡，这种平衡长期以来因冰冻而固定。

The retreat of the polar ice cap is making the region easier to work in, and there is thought to be lots of oil and gas to tap.

北极冰盖的消融使得在该地区作业较为容易，而且该地区储藏有大量可开发的石油和天然气。

The swirling troughs of Mars's north polar ice cap are seen above in a recently released picture from the no-longer-operating Mars Global Surveyor orbiter, whose mission was terminated in 2007.

不再运行的火星环球探测轨道飞行器（2007年终止使命）发回的最新照片上可见火星北极冰帽旋转的低谷…

Platteville, Colorado: I'm curious as to weather the polar ice cap melt has increased pressure o the earth's plates?

普莱维尔，科罗拉多州(PlattevilleColorado) ：我很好奇极地冰盖的融化会不会增加地球版块的压力。

As Stavridis noted: "Melting of the polar ice cap is a global concern because it has the potential to alter the geopolitical balance in the Arctic heretofore frozen in time."

正如斯塔夫里蒂斯所述：“融化的北极冰帽正在引起全世界的关注，因为它有可能改变这个一直被冷冻着的地区的地缘政治平衡。”

Al Gore, former US vice president, told the UN climate conference Monday that new data suggests the Arctic polar ice cap may disappear in the summertime as soon as 5-7 years from now.

美国前副总统戈尔14日在联合国气候大会上说，新数据表明，从现在起5-7年内，北极冰帽可能将在夏天消失。

Of course, in time the polar ice cap will melt.

当然了，极地的冰帽迟早也会融化。

The size of the North Polar Ice Cap in the month of September is only half the size it was a mere 50 years ago.

北极冰覆盖在今年九月份的大小，只相当于五十年前的一半。
