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.'

I. 描述火星之旅的英文小短文70词
光阴似箭，转眼就到了2025年，已成为发明家的找发明了磁悬浮火箭，这个火箭可以到任何星球去，于是我打算乘磁悬浮火箭到火星去旅行。
“嗖”的一声，还没来得及眨眼，磁悬浮火箭一下子就到了火星。我踏上火星，碰到了一位火星人，只见火星人打量了一下我，很有礼貌地说：“欢迎你，地球人。”我惊奇地问：“你怎么也会我们地球人的语言?”火星人微笑着说：“你不知道宇宙人的沟通是无障碍的吗?既然际是第一次来火星，那我就带你参观一下火星吧!”
于是，我们来到了街道，只见这里绿草如菌，鲜花盛开，马路上一点灰尘也没有，甚至连一辆汽车也没有。火星人说：“我们火星人一般都步行，如果要去很远的地方，就乘超光速飞船。”哇，原来外星人的交通工具这么先进啊!
接着我们离开了街道，来到居民区。一到小区，我大吃一惊，只见一幢幢高楼耸入云西，看样了足足有1000层，而且没有电梯，只在一楼的楼梯处安装了一台收音机模样的装备。火星人说：“这可不是普通的收音机，你只要对它说到几层楼，它就会送你上去。”我怀着激动的心情对收音机说：“我要到110层楼!”话音刚落，收音机就把我送到了110层楼。等我回过神来时，收音机又不见了。火星人又说：“这收音机会随时隐身，你只要向它发出命令，它就会自动现身送你上下楼。”哦，原来在火星上下楼是这么简单呀!
然后，火星人又带我参观了空气处理厂和水处理厂。这两个工厂十分清洁，没有一点臭味。我很奇怪，问火星人：“地球上的水和空气都受到了污染，可在火星上为什么就不一样了呢?”火星人告诉我：“因为这些水和空气都被净化器处理过了，人们呼吸的空气绝对保证清新。”我想：原来火星上的空气和水都是洁净、无污染的呀!
接着，火星人又带我参观了博物馆、超市、植物园……一切都是那么新奇，那么有趣。
时候不早了，我依依不舍地和火星人告别，心想：地球也能像火星上这么整洁有序，那该多好呀!
J. 以去火星为辩论作文一英语作文
红袖添香的雅致抄、青梅煮酒袭的风趣,还有,雨夜读书的清幽.
还记得,小时候,好玩.还因为这样闯祸了,被父亲痛打了一顿.当时不懂得把书好好珍惜,只知道玩.把父亲心爱的那本《水浒传》撕下几页,用来折成小时候最流行的纸飞机和同伴一起玩耍.被打后还不理解为什么父亲会为这几页纸打了心爱的我,但从此以后,我再不敢对书这样残忍了.慢慢还懂得了珍惜它!
我上小学了.读书让我知道：冰心老奶奶对我们的殷切期望、列宁让我们知道了怎样才算是一个诚实的孩子、狼牙山五壮士让我们对英雄有了敬慕.随着我逐渐地成长,读的书也越来越多了,原来的小人书、机器猫、故事会,都不能满足我对知识的那种渴求.于是努力寻求更多更喜欢的书籍来陪伴我度过快乐的时光.
