英语作文关于火星70词并翻译

火星是太阳系九大行星之一,按离太阳由近到远的顺序,火星排在地球的后面,列为第四。它的平均直径为6790公里,约为地球直径的一半。它的密度也比地球小,为3.933克/立方厘米(地球为5.52克/立方厘米)。火星与太阳的平均距离为228000000公里,环绕太阳一圈约相当于地球上的687天。火星上的一天相当于地球上的24小时37分22.6秒,比地球的一天稍长一点儿。火星有两个小卫星:火卫一和火卫二。火星的自转轴同地球一样,也是倾斜的,同时因为它也具有大气,所以也和地球一样有四季节变化。火星表面的平均大气温度为零下23摄氏度。火星没有可检测出的磁场,连同它密度小的情况,可以认定它没有大型的金属内核

Mars is one of the nine major planets of the solar system, according to from the sun by the near to far order, Mars row behind the earth, as the fourth. Its mean diameter is 6790 km, which is about half the diameter of the earth. Its density is smaller than the earth, 3.933 grams / cubic centimeter (the earth is 5.52 g / cm3). The average distance to Mars from the sun is 228000000 km, a ring around the sun, the equivalent of about 687 earth days. The day on Mars is equivalent to the earth in 24 hours 37 minutes and 22.6 seconds, slightly longer than the earth one day a little. Mars has two small moons Phobos and Deimos. The rotation shaft of Mars like the earth, is tilted, and because it also has an atmosphere, so it just like the earth there are four seasonal variation. The average air temperature of the surface of Mars to minus 23 degrees celsius. Mars has no detectable magnetic field, together with its density is small, can be concluded it had large metal core

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 productive 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 productivity 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.'
