带去的其他设备还可以用火星大气中天然的氮气、二氧化碳和表面的冰水制造出肥料、甲烷和氧气。

Additional equipment carried over could also produce fertilizer , methane and oxygen using the atmosphere 's natural elements of nitrogen , carbon dioxide and its surface of ice water .

稀薄的大气导致本来在地球大气中效率极佳的碟形构造在进入火星大气时效率底下。

The craft was shaped as a giant saucer-a form that is very efficient as an air brake , when it is entered into the atmosphere with its huge cross section perpendicular to the trajectory of descent .

生命无法在火星的大气环境下生存。

The atmosphere of Mars could not support life .

这一团队将在地球的实验室中模拟火星的大气条件，使用来自秘鲁PampasdeLaJoya沙漠的一种土壤，这种土壤据称几乎与火星上发现的土壤完全相同。

The team will replicate Martian atmospheric conditions in a laboratory , using soil from Peru 's Pampas de La Joya desert - reportedly nearly identical to that found on the Red Planet .

事实上，在火星的大气中已经检测到甲烷和甲醛的存在。

In effect , methane and formaldehyde have been detected in the Martian atmosphere .

股流在温暖地季节，春天和夏天冒出，可能是冰块开裂气体蒸发，使得甲烷释放到火星的大气当中。

The plumes were emitted during the warmer seasons , spring and summer , perhaps because ice blocking cracks and fissures vaporized , allowing methane to seep into the Martian air .

这样，太阳风和太阳的紫外辐射赋予火星外层大气中的原子和粒子一个电荷，然后由太阳风产生的电场将带电粒子一扫而空。

Instead , the solar wind and the sun 's UV radiation give an electric charge to atoms and particles in Mars outer atmosphere . Then electric fields generated by the solar wind the charged particles .

火星上的大气压力只有地球的100分之1。

The atmospheric pressure on Mars is about 1 / 100 of that on earth .

通过了解火星表面的大气变化，该团队希望有助于在地球上建立更多高效、精确的环境模拟中心。

By understanding atmospheric changes on the surface of Mars , the team hopes it will help build more dynamic and accurate simulation centers on Earth .

白天，这些植物将承受高强度太阳紫外线照射，这是由于火星稀薄的大气不含有臭氧层来像地球一样阻挡紫外线；

During the day , the plants would have to endure high levels of solar ultraviolet radiation , because the thin Martian atmosphere has no ozone to block it like the Earth 's atmosphere does .

火星地形对火星大气运动的影响及火星尘暴发生的可能机制

The Effects of Topography of the Mars upon the Atmospheric Motion of the Mars and the Possible Mechanism That Produced the Dust Storm on the Mars

该研究中心将逼真还原火星的地貌和大气状况，以供未来太空种植研究之用。太空种植将为探测火星等其他太阳系行星的载人任务提供补给。

It would create a perfect replica of the Martian landscape and atmosphere for future research into space farming that could serve manned missions to Mars and other planets in the solar system .

本文在准地转模式的假定下，讨论了火星地形对火星大气的影响，并根据文章所提供的信息对火星尘暴发生的物理机制作了粗略的解释。

In this paper , the influence of the surface topography to the atmosphere of the Mars is examined on the assumption of a quasi-geostrophic model , and a rough explanation is given for the possible physical mechanism that produces the dust storm on the Mars .

研究报道甲烷有可能是地球早期的温室气体。在火星的早期，它与地球十分相似，那么早期的火星大气中也可能存在大量的甲烷。

It has been proposed that methane is the greenhouse gas in early Earth , methane could be abundant in the atmosphere of early Mars due to the similarities between early Mars and Earth .

Over the course of a full Martian year , Surveyor will return an unprecedented amount of data regarding Mars ' surface features , atmosphere , and magnetic properties .

这个结论一度很难在火星气候模型中说得通。火星气候模型显示，早期火星冰冷，大气稀薄，不支持大量静态水的存在，不可能有流淌了几百万年的河流。

This conclusion has been difficult to square with climate models , which point to a colder early Mars with a thin atmosphere that could not have supported large bodies of standing water , or rivers that ran for millions of years .
