美國"毅力"號(hào)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(hào)火星車于本周四（2月18日）下午3點(diǎn)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?！耙懔Α碧?hào)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(jiān)合眾國和全球太空探索的關(guān)鍵時(shí)刻之一。我們正處于發(fā)現(xiàn)和磨練的時(shí)期，而這次著陸改寫了教科書?；鹦?020“毅力”號(hào)任務(wù)代表了美國在最具挑戰(zhàn)性的形勢(shì)下堅(jiān)忍不拔的精神，啟發(fā)和推動(dòng)了科學(xué)與探索。”

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”號(hào)是美國宇航局迄今為止發(fā)射的技術(shù)最先進(jìn)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(hào)火箭發(fā)射升空后，“毅力”號(hào)在6個(gè)多月的時(shí)間里飛行了2.93億英里（4.7億千米）才到達(dá)了火星?！耙懔Α碧?hào)將在火星上停留近兩年，尋找遠(yuǎn)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(zhǔn)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(gè)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(jìn)實(shí)驗(yàn)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(hào)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(hào)平均每個(gè)火星日可以行駛650英尺，包含7個(gè)科學(xué)設(shè)備、一個(gè)能伸到7英尺長的機(jī)器手臂，還有一個(gè)鑿巖機(jī)。這個(gè)核動(dòng)力火星車使用的是美國能源部提供的钚發(fā)電機(jī)。
