8月6日,一辆跟SUV同样大小的探测器,以每小时20920千米的速度闯入火星大气层,它就是“好奇号”。它要在这个数十亿年前温暖且充满水的星球上寻找碳、甲烷和其他有机体的踪迹,并且研究其地形、化学和可能的生物。“好奇号”能够兼职这么多功能,多亏了随身携带的秘密武器。它的重量超过900公斤,约是2004年登陆火星的“勇气号”和“机遇号”重量的5倍。这么重的身躯以每小时2万公里的速度降
On August 6, a detector of the same size as the SUV broke into the Martian atmosphere at a speed of 20,920 kilometers per hour. It was a “curiosity”. It wants to find traces of carbon, methane, and other organisms on this warm, water-filled planet billions of years ago, and study its topography, chemistry, and possible creatures. “Curiosity” can be used as part-time, thanks to the secret weapon that can be carried around. It weighs more than 900 kilograms, about five times the weight of Mars’s “Glory” and “Optimum” that landed on Mars in 2004. Such a heavy body descends at a speed of 20,000 kilometers per hour
