Interplanetary robot
Mars fascinates scientists because of its similarity to Earth, and it fascinates the public because our myth of 'Martians' is a vision of life beyond Earth. The Mars adventure continues with the launch of a robot vehicle by UK scientists. It's part of project to build an 'autonomous robotic scientist' to explore the Martian surface and is key to the European Space Agency's 2011 ExoMars mission.
The six-wheeled vehicle housing a myriad of scientific instruments and detectors is the Mars rover, nicknamed 'Bridget'. Astrium, an EADS company, are developing the ExoMars rover prototype and coordinating its technologies with other UK-based institutions.
Test bed to prove the rover's stamina
Searching for a terrain similar to that found on Mars, the team took the rover to El Teide National Park in Tenerife. Lester Waugh, leading the EADS Astrium team, explains, 'The rover's not waterproof so we need good weather to test it in, but also the conditions need to be dry as any moisture affects the way the sand reacts under the wheels.'
Solar panels will supply power and radioisotope heater units will help it withstand the extreme cold on Mars. The team is optimizing the performance of the wheels, suspension, the drive system, so it doesn't dig itself in on tricky terrain.
Taking up to twenty minutes for radio signals to reach Earth demands a powerful navigation system to allow the rover to operate solo so they are also developing next generation computer software capabilities.
Maximizing proctive science time
The rover will land on Mars packed to capacity with scientific gadgets designed to be as light and as small as possible. These include: a microseismometer searching for Marsquakes; an advanced meteorological system analysing the Martian weather; a wide-angled panoramic camera which will be our eyes on Mars; a Raman spectrometer providing rock analyses; even a mole to retrieve samples from beneath the surface.
The extended development time is essential for rigorous testing, as Waugh explains, 'When we put things in space we have to make sure that they'll survive the radiation environment, the extremes of heat and cold. Our science proctivity is crucial, and malfunctions may affect that. The more science we get back the better justification there is for spending more money on planetary exploration.'

⑨ 英文介紹火星
火星
火星是八大行星之一，按照距離太陽由近及遠的次序為第四顆。肉眼看去，火星是一顆引人注目的火紅色星，它緩慢地穿行於眾星之間，在地球上看，它時而順行時而逆行，而且亮度也常有變化，最暗時視星等為+1.5，最亮時比天狼星還亮得多，達到-2.9。由於火星熒熒如火，亮度經常變化，位置也不固定，所以中國古代稱火星為「熒惑」。而在古羅馬神話中，則把火星比喻為身披盔甲渾身是血的戰神「瑪爾斯」。在希臘神話中，火星同樣被看做是戰神「阿瑞斯」。有時火星也被稱為「紅色行星」。
質量 6.421e+23 kg
赤道半徑 3,397.2 km
平均密度 3.94 gm/cm3
平均日距 227,940,000 km
自轉周期 24.6229 小時
公轉周期 686.98 天
赤道地表重力 3.72 m/sec2
赤道逃逸速度 5.02 km/sec
最低地表溫度 -140 ℃
平均地表溫度 -63 ℃
最高地表溫度 20 ℃
大氣壓力 0.007 bars
大氣組成 二氧化碳 95.32% 氮 2.7% 氬 1.5% 氧 0.13% 一氧化碳 0.07% 水 0.03% 其他 0.000291%
火星表面的土壤中含有大量氧化鐵，由於長期受紫外線的照射，鐵就生成了一層紅色和黃色的氧化物。誇張一點說，火星就像一個生滿了銹的世界。由於火星距離太陽比較遠，所接收到的太陽輻射能只有地球的43％，因而地面平均溫度大約比地球低30多攝氏度，晝夜溫差可達上百攝氏度。在火星赤道附近，最高溫度可達20℃左右。火星上也存在大氣。其主要成份是二氧化碳，約佔95％，還有極少量的一氧化碳和水汽。
火星比地球小，赤道半徑為3395公里，是地球的一半， 體積不到地球的1/6，質量僅是地球的1/10。火星的內部和地球一樣，也有核、幔、殼的結構。
火星的自轉和地球十分相似，自轉一周為24小時37分22.6秒。火星上的一晝夜比地球上的一晝夜稍長一點。火星公轉一周約為687天，火星的一年約等於地球的兩年。
火星有兩個衛星。靠近火星的一個叫火衛一，較遠的一個叫火衛二。由於火星在希臘神話中被看做是戰神阿瑞斯，所以天文學家以阿瑞斯的兩個兒子——福波斯和德瑞斯命名它的兩顆衛星。
火衛一
Phobos
火衛一呈土豆形狀，一日圍繞火星3圈，距火星平均距離約9378公里。
它是火星的兩顆衛星中較大，也是離火星較近的一顆。火衛一與火星之間的距離也是太陽系中所有的衛星與其主星的距離中最短的，從火星表面算起，只有6000千米。它也是太陽系中最小的衛星之一。
在希臘神話中，火衛一是阿瑞斯（火星）和阿芙羅狄蒂（金星）的一個兒子。「phobos」在希臘語中意味著「恐懼」（是「phobia」－恐懼的構詞成分）。
火衛一在1877年由Hall發現，1971年由「水手9號」首次拍得照片，並由1977年的「海盜1號」、1988年的「火衛一號」進行觀測。
火衛二
Deimos
火衛二是火星的兩顆衛星中離火星較遠也是較小的一顆，也是太陽系中最小的衛星。
公轉軌道: 距火星23,459 千米
衛星直徑: 12.6 千米 (15 x 12.2 x 11)
質量: 1.8e15 千克
在希臘神話中，火衛二是阿瑞斯（火星）與阿芙羅狄蒂（金星）的另一個兒子。「deimos」在希臘語中意味著「驚慌」。火衛二在1877年8月10日被Hall發現，在1977年由海盜1號首次拍得其照片。 火衛二和火衛一是由像C型小行星那般的富含碳的岩石組成的，並且它們都有很深的地坑。火衛二和火衛一可能是由於小行星的擾動與木星的作用才使它們圍著火星運動的。
火星上有明顯的四季變化，這是它與地球最主要的相似之處。但除此之外，火星與地球相差就很大了。火星表面是一個荒涼的世界，空氣中二氧化碳佔了95%。濃厚的二氧化碳大氣造成了金星上的高溫，但在火星上情況卻正好相反。火星大氣十分稀薄，密度還不到地球大氣的1%，因而根本無法保存熱量。這導致火星表面溫度極低，很少超過0℃，在夜晚，最低溫度則可達到-123℃。
這是美國宇航局海盜號環繞器拍攝的火星全球照片。圖中可以清晰地看到巨大的「水手谷」。水手谷長約4000公里，深度約8公里。(USGS)
火星被稱為紅色的行星，這是因為它表面布滿了氧化物，因而呈現出鐵銹紅色。火星表面的大部分地區都是含有大量的紅色氧化物的大沙漠，還有赭色的礫石地和凝固的熔岩流。火星上常常有猛烈的大風，大風揚起沙塵能形成可以覆蓋火星全球的特大型沙塵暴。每次沙塵暴可持續數個星期。
Mars
Mars is one of the eight planets, according to the Sun from near and far away from the order of the fourth stars. Looked the naked eye, Mars is an eye-catching fire red stars, which slowly walk through in the trans-pacific, between the Earth's point of view, it is sometimes shun row and retrograde, but also often change the brightness, the most dark, as the magnitude +1.5, the brightest when the much brighter than Sirius has also reached -2.9. As fiery Mars Yingying, brightness constantly changing, the location is not fixed, so that Mars in ancient China as "Ying Huo." In ancient Roman mythology, put the Mars compared to wearing armor was covered in blood of the God of War "Mars." In Greek mythology, Mars also be seen as God of War "Ares." Mars is sometimes also called "Red Planet."
Quality 6.421e +23 kg
Equatorial radius 3,397.2 km
The average density of 3.94 gm/cm3
Average daily distance 227,940,000 km
Rotation cycle of 24.6229 hours
Orbital period 686.98 days
Equatorial surface gravity 3.72 m/sec2
Equatorial escape velocity 5.02 km / sec
Minimum surface temperature -140 ℃
Average surface temperature of -63 ℃
The maximum surface temperature of 20 ℃
Atmospheric Pressure 0.007 bars
Of atmospheric carbon dioxide, 95.32% nitrogen composition of 2.7% Argon 1.5% Oxygen 0.13% Carbon monoxide 0.07% Water 0.03% Others 0.000291%
The surface of Mars soil contains large amounts of iron oxide, e to long term ultraviolet exposure, generating a layer of iron oxide red and yellow. Exaggeration to say that Mars is like a health filled with rusty world. As the distant planet from the sun, the solar radiation received only 43% of the Earth, so Earth's average surface temperature of about less than 30 degrees Celsius, up to hundreds of degrees Celsius temperature difference between day and night. On Mars near the equator, the maximum temperature up to about 20 ℃. There are also the atmosphere on Mars. Its main component is carbon dioxide, accounting for about 95%, there is a very small amount of carbon monoxide and water vapor.
Mars smaller than Earth's equatorial radius of 3395 kilometers, half of the planet, smaller than Earth's 1 / 6, the quality of the Earth is only 1 / 10. Mars, like Earth's interior and, there are core, mantle and shell structure.
To the rotation of Mars and Earth are very similar to the rotation a week for 24 hours 37 minutes 22.6 seconds. A day and night on Mars than on Earth in a slightly longer day and night. Mars revolution is about 687 days a week, Mars year, equivalent to about two years of the Earth.
Mars has two satellites. Near Mars called Phobos, one farther away is called Deimos. As in Greek mythology, Mars was seen as a god of war Ares, so astronomers to Ares two sons - Phobos and Idris named its two satellites.
Phobos
Phobos
Phobos was a potato shape, on the 1st 3 laps around Mars from the Mars average distance is about 9378 kilometers.
It is the larger of Mars's two satellites, but also from the Mars closer to one. Phobos and Mars is the distance between the satellite and its solar system, all the main stars in the shortest distance from the surface of Mars date, only 6,000 km. It is also one of the solar system's smallest satellite.
In Greek mythology, Phobos is Ares (Mars) and Aphrodite (Venus) and a son. "Phobos" in Greek means "fear" (a "phobia" - fear of word-building components).
Phobos in 1877 by Hall discovered in 1971 by the "Mariner 9" first looks pictures by 1977, "Viking 1", 1988's "Phobos" observations.
Deimos
Deimos
Deimos is the two satellites of Mars from the Mars is also a smaller one farther away, but also the smallest in the solar system satellites.
Orbits: 23,459 km from Mars
Satellite has a diameter: 12.6 km (15 x 12.2 x 11)
Quality: 1.8e15 kg
In Greek mythology, Deimos is the Ares (Mars) and Aphrodite (Venus) and another son. "Deimos" in Greek means "alarm." Phobos 2 in the August 10, 1877 by Hall discovered in 1977 by Viking 1, the first photograph in the photo. Deimos and Phobos is made of, like C-type asteroid like that of the composition of carbon-rich rocks, and they have a very deep pit. Deimos and Phobos may be e to disturbance of asteroids and Jupiter's role was to make them around Mars movement.
A clear four seasons on Mars change, which is the most important similarities with the Earth. But beyond that, the big difference between Mars and Earth had. The surface of Mars is a desolate world, the air of carbon dioxide accounted for 95%. Thick carbon dioxide atmosphere on Venus caused the high temperature, but on Mars the situation is just the opposite. Martian atmosphere is very thin, density is less than 1% of the Earth's atmosphere and thus unable to save calories. This has led to the Martian surface temperature is very low, rarely more than 0 ℃, at night, the lowest temperature can reach -123 ℃.
It is surrounded by NASA's Viking Mars Global device taken photos. Figure can clearly see the huge "Mariner Valley." Valles Marineris is about 4,000 km, a depth of about 8 km. (USGS)
Mars is known as the red planet, it is because its surface covered with oxide, thus showing a rust red. In most parts of the surface of Mars are rich in red oxide desert, as well as ocher gravel land and solidified lava flows. Mars often have fierce winds, strong winds stirring up the st can form around the world can cover large Martian st storms. Each st storms that last several weeks.
