美国"毅力"号火星车成功着陆火星

NASA has unveiled the first pictures from its fifth Mars rover, Perseverance, after a successful landing on the red planet's Jezero crater at approximately 3:55 pm Thursday.

“毅力”号火星车于本周四（2月18日）下午3点55分左右在火星的耶泽罗陨石坑成功着陆后，美国宇航局发布了第一批由其传回的照片。“毅力”号是美国宇航局的第五辆火星巡游车。

"This landing is one of those pivotal moments for NASA, the United States, and space exploration globally – when we know we are on the cusp of discovery and sharpening our pencils, so to speak, to rewrite the textbooks," acting NASA Administrator Steve Jurczyk said in a press release. "The Mars 2020 Perseverance mission embodies our nation's spirit of persevering even in the most challenging of situations, inspiring, and advancing science and exploration."

美国宇航局代理局长史蒂夫·尤尔奇克在一份新闻发布稿中称：“此次着陆是美国宇航局、美利坚合众国和全球太空探索的关键时刻之一。我们正处于发现和磨练的时期，而这次着陆改写了教科书。火星2020“毅力”号任务代表了美国在最具挑战性的形势下坚忍不拔的精神，启发和推动了科学与探索。”

Perseverance, the most technologically advanced robot NASA has sent to date, traveled 293 million miles to reach Mars over the course of more than six months after launching on a United Launch Alliance Atlas V rocket from Cape Canaveral Space Station on July 30. It will remain on Mars for nearly two years, searching for signs of ancient life and exploring the planet's surface.

“毅力”号是美国宇航局迄今为止发射的技术最先进的遥控设备。去年7月30日从卡纳维拉尔角空间站搭载联合发射联盟的阿特拉斯5号火箭发射升空后，“毅力”号在6个多月的时间里飞行了2.93亿英里（4.7亿千米）才到达了火星。“毅力”号将在火星上停留近两年，寻找远古生命迹象，探索火星表面。

The mission will help prepare the agency for future human exploration on Mars in the 2030s.

该任务将有助于美国宇航局为2030年后人类探索火星做好准备。

The $2.7 billion rover, built in NASA's Jet Propulsion Laboratory in Pasadena, Calif., is about 10 feet long, 9 feet wide, seven feet tall and about 2,260 pounds, roughly 278 pounds heavier than its predecessor, Curiosity.

这个耗资27亿美元（约合人民币175亿元）的火星车是在美国宇航局位于加州帕萨迪纳市的喷气推进实验室制造的，车体长10英尺（约3米），宽9英尺，高7英尺，重2260磅（约1025千克），比它的前任“好奇”号火星车大约重278磅。

Perserverance is designed to drive an average of 650 feet per Martian day and features seven scientific instruments, a robotic arm that reaches about seven feet long, a rock drill. It is nuclear powered, using a plutonium generator provided by the US Department of Energy.

按照性能要求，“毅力”号平均每个火星日可以行驶650英尺，包含7个科学设备、一个能伸到7英尺长的机器手臂，还有一个凿岩机。这个核动力火星车使用的是美国能源部提供的钚发电机。
