NASA launches spacecraft to gauge if Jupiter's moon Europa can host life 探寻地外生命,NASA巨型太空船飞向木卫二 NASA launched a spacecraft from Florida on Monday on a mission to examine whether Jupiter's moon Europa has conditions suitable to support life, with a focus on the large subsurface ocean believed to be lurking beneath its thick outer shell of ice. The U.S. space agency's Europa Clipper spacecraft blasted off from the Kennedy Space Center in Cape Canaveral on a SpaceX Falcon Heavy rocket under sunny skies. The robotic solar-powered probe is due to enter orbit around Jupiter in 2030 after journeying about 1.8 billion miles (2.9 billion km) in 5-1/2 years. 美国国家航空航天局(NASA)周一从佛罗里达州发射了一艘宇宙飞船,其任务是研究木星的卫星欧罗巴(木卫二)是否具备支持生命存在的条件,将重点考察据信在其厚厚的冰壳下潜藏着的大型地下海洋。 在晴朗的天空下,美国航天局的 “欧罗巴快船”航天器搭乘太空探索技术公司(SpaceX)的猎鹰重型火箭从卡纳维拉尔角的肯尼迪航天中心发射升空。 这艘以太阳能为动力的机器人探测器将在5年半的时间里飞行约18亿英里(约合29亿公里),于2030年进入木星轨道。 ☞ gauge 英 [ɡeɪdʒ] 美 [ɡeɪdʒ] n. 测量仪器;宽度,厚度;(测量或判断的)尺度,标准;(铁道的)轨距;(枪管的)口径;(汽车)胎压计 v. 估计,判断;测量 ☞ lurk 英 [lɜːk] 美 [lɜːrk] vi. 潜伏;潜藏;埋伏 n. 潜伏;埋伏 复数lurks 第三人称单数lurks 现在分词lurking 过去式lurked 过去分词lurked If someone lurks somewhere, they wait there secretly so that they cannot be seen, usually because they intend to do something bad. 潜藏 He thought he saw someone lurking above the chamber during the address. 他以为他看见有人在演讲时潜藏在了会议室里。 ☞ 木星的冰冻卫星木卫二很可能是在太阳系中检查外星生命迹象的最佳地点之一,但人类要做的是首先抵达那里。NASA的“欧罗巴快艇”(Europa Clipper)太空飞船采用SpaceX的“重型猎鹰”火箭作为动力。“重型猎鹰”是有史以来人类建造的动力最强的火箭之一。
