美国宇航局探测器 "毅力"号飞向火星寻找生命迹象

周四，美国宇航局发射了其最新的火星车- "毅力号"。这次任务最引人注目的一个技术是火星车会将火星大气中的二氧化碳转化为氧气。"未来，火箭推进剂和宇航员呼吸的氧气就可以用这种方式来产生。"NASA说。这辆重2260磅、长10英尺的火星车是美国宇航局有史以来最大、最重的机器人火星车（它的名字来自于弗吉尼亚州的一名七年级学生）。"毅力号"也是美国国家航空航天局派往火星的第四辆漫游车。

NASA launched its latest Mars rover, dubbed Perseverance, on Thursday. The most dramatic goal of the mission will be the rover’s attempt to demonstrate a technology that converts carbon dioxide in the Martian atmosphere into oxygen. “In the future, oxygen generated this way could be used by astronauts as rocket propellant and for breathing,” NASA said. The ability to do so will be a critical consideration in planning human landings and bases on Mars. The 2,260-pound, 10-feet long rover is the biggest and heaviest robotic Mars rover NASA has ever built (its name came from a Virginia seventh-grader). It’s the fourth sent to Mars by the National Aeronautics and Space Administration.  source
