NASA Ready to Study Heart of Mars(NASA准备去研究火星的内部)

NASA 将要走上研究火星内部的征程。

NASA安排于最早在5月5日用自己的Geodesy和InSight号(一个固定的着陆器)在火星表面上降落,将会成为第一个献身于探索火星深深的内部的任务。它也会成为自从阿波罗登月器后 NASA第一个将一个地震仪(一种测量地震的仪器)放在另外一个行星的土壤上的任务。

InSight号携带了一批敏感度高的仪器去收集数据。和一个探测器的任务不同,这些仪器需要一个固定的着陆器,它能够被小心地放置在火星表面上和表面下。

在某种 意义上,火星是外部行星的下一个门——一个附近的例子,展现出气体、尘埃和热如何混合、排列在一起,变成一个星球。仔细的观测火星内部的深处将让科学家们懂得它的地壳、覆盖物和地核与地球的是多么的不同。

NASA is about to go on a journey to study the interior of Mars.

Scheduled to launch as early as May 5, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight), a stationary lander, will be the first-ever mission dedicated to exploring Mars’ deep interior. It also will be the first NASA mission since the Apollo moon landings to place a seismometer, a device that measures quakes, on the soil of another planet.

InSight carries a suite of sensitive instruments to gather data and, unlike a rover mission, these instruments require a stationary lander from which they can carefully be placed on and below the Martian surface.

In a sense, Mars is the exoplanet next door – a nearby example of how gas, dust and heat combine and arrange themselves into a planet. Looking deep into Mars will let scientists understand how different its crust, mantle and core are from Earth.

火星气候的简介

关于温度

火星的平均气温是-64°F。在中午的时候,火星的气温能够达到80°F。它在冬季里温度能下降到-199°F。它的气温也和海拔有关,你越往上爬,气温降低得就越快。

关于大气层

火星稀薄的大气层有96%的二氧化碳,1.93%的氩, 1.89%的氮和一些氧气和水。它的大气层里拥有直径为1.5微米的小颗粒,这就是它的外表是黄褐色的原因。它的大气压强大约是地球海平面的1%。(0.4到0.87帕)

关于氧气

在火星的两极有一大片的白色固体——干冰(固体二氧化碳)。因为二氧化碳里面含有氧元素,所以可以通过加热干冰使干冰变成气态的二氧化碳。这样做不仅能够使火星的氧气体积增加,而且也增厚火星的大气层。

关于湿度

火星的湿度跟温度的起伏紧密相连。夜晚很冷,相对的湿度能上升到80%到100%。相反,白天的湿度就相对低了很多。

关于水资源

在火星的中央地区,科学家们已经发现火星地表下仅几尺就藏有几层冰。NASA很早就发现火星的高纬度地区地下面很浅的地方就有冰,后来又发现中纬度地区也拥有同样的特点。

Volunteer to Settle Mars

Who Are We?

We are students of the JianHua Experimental School. We are a English team. Our slogan(口号) is “King of Europe”

Value of This Volunteering :

1.Let more and more people in China know the mars immigration(火星移民)

2.Help China be the first country to live on mars.

Why Will We Do It?

If we don’t do it, China will  fall behind the world because this century(世纪) is the age of mars immigration(火星移民的时代). Moreover(而且), the  US is already had  Elon Musk and his SpaceX.

What  Will We Do?

We will publish some articles on this website. They’re about:

1. How to increase the thickness(厚度) of the atmosphere on mars?

2. What plants can probably survive(生存) on mars?

3. What probes(探测器) can detect( 探测)more exactly about the information of mars, like the atmosphere(大气层), the water, the climate(气候), the soil(土壤) and so on.

4.  What’s rockets can be lighter(更轻), cheaper(更便宜) and quicker?

Frequently Asked Questions(FAQ)

Question 1: Why must human beings study about how to get and live on mars?

Question 2: Why we can settle mars, not the other seven biggest planets?

Question 3: When probably will the first crowds(群) of human race live on mars?

Answers of The Questions

Answer 1: It’s because people want to do something to make human race a long-living species(物种), for that protecting(保护) the environment is great but not enough.

Answer 2: It’s because mars is the most similar(最像) to earth. The other planets are too cold, too hot, haven’t seen traces of water or can’t produce(产生) oxygen(氧气).

Answer 3: They will probably live on mars around 2025.

Finally, we hope those who are interested in this issue(问题)join “the king of Europe”!

Thank you !
