美國"毅力"號火星車成功著陸火星

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”號火星車于本周四（2月18日）下午3點55分左右在火星的耶澤羅隕石坑成功著陸后，美國宇航局發(fā)布了第一批由其傳回的照片。“毅力”號是美國宇航局的第五輛火星巡游車。

"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."

美國宇航局代理局長史蒂夫·尤爾奇克在一份新聞發(fā)布稿中稱：“此次著陸是美國宇航局、美利堅合眾國和全球太空探索的關(guān)鍵時刻之一。我們正處于發(fā)現(xiàn)和磨練的時期，而這次著陸改寫了教科書。火星2020“毅力”號任務(wù)代表了美國在最具挑戰(zhàn)性的形勢下堅忍不拔的精神，啟發(fā)和推動了科學(xué)與探索?！?/p>

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”號是美國宇航局迄今為止發(fā)射的技術(shù)最先進的遙控設(shè)備。去年7月30日從卡納維拉爾角空間站搭載聯(lián)合發(fā)射聯(lián)盟的阿特拉斯5號火箭發(fā)射升空后，“毅力”號在6個多月的時間里飛行了2.93億英里（4.7億千米）才到達了火星。“毅力”號將在火星上停留近兩年，尋找遠古生命跡象，探索火星表面。

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

該任務(wù)將有助于美國宇航局為2030年后人類探索火星做好準備。

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.

這個耗資27億美元（約合人民幣175億元）的火星車是在美國宇航局位于加州帕薩迪納市的噴氣推進實驗室制造的，車體長10英尺（約3米），寬9英尺，高7英尺，重2260磅（約1025千克），比它的前任“好奇”號火星車大約重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”號平均每個火星日可以行駛650英尺，包含7個科學(xué)設(shè)備、一個能伸到7英尺長的機器手臂，還有一個鑿巖機。這個核動力火星車使用的是美國能源部提供的钚發(fā)電機。
