1.It's the perfect time for the DART mission to occur. 这是DART任务执行的最佳时机。  2.Didymos and Dimorphos will be relatively close to Earth -- within 6,835,083 miles (11 million kilometers) -- in September 2022. 在2022年9月，飞船蒂迪莫斯号和天体迪莫菲斯将相对接近地球——在6835083英里(1100万公里)之内。 3.The spacecraft will come speeding in at about 15,000 miles (24,140 kilometers) per hour, targeting Dimorphos, said Nancy Chabot, DART coordination lead at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. 位于马里兰州劳瑞尔的约翰霍普金斯应用物理实验室的DART协调主管南希·查伯特说，飞船将以大约15,000英里(24,140公里)每小时的速度靠近，目标就是迪莫菲斯。 4.A camera on the spacecraft, called DRACO, and autonomous navigation software will help the spacecraft detect and collide with Dimorphos. 飞船上的一个名为DRACO的摄像头和自动导航软件将帮助飞船探测到迪莫菲斯并与之碰撞。 5.DRACO is short for Didymos Reconnaissance & Asteroid Camera for OpNav. DRACO是蒂迪莫斯侦察和小行星相机的缩写。  6.The mission's aim is to deliberately crash into Dimorphos to change the asteroid's motion in space, according to NASA. 据美国宇航局称，该任务的目标是故意撞击迪莫菲斯，以改变小行星在太空中的运动。 7.This collision will be recorded by LICIACube, or Light Italian Cubesat for Imaging of Asteroids, a companion cube satellite provided by the Italian Space Agency. 这次碰撞将由意大利航天局提供的一颗伴星LICIACube(意大利小行星成像轻立方体卫星)记录下来。 8.It's the Italian Space Agency's first deep space mission. 这是意大利航天局的首次深空任务。 9.The briefcase-size CubeSat will travel on DART and then be deployed from it prior to impact so it can record what happens. 这颗公文包大小的立方体卫星将在DART上运行，并在撞击前从其上方开始拍摄，这样它就可以记录发生了什么。  10.Three minutes after the impact, the CubeSat will fly by Dimorphos to capture images and video. 撞击三分钟后，这颗立方体卫星将飞越迪莫菲斯，以捕捉图像和视频。 11.The video of the impact will be streamed back to Earth, which should be "pretty exciting," said Elena Adams, DART mission systems engineer at the Johns Hopkins Applied Physics Laboratory. 撞击的视频将被传送回地球，这应该“非常令人兴奋”，埃琳娜·亚当斯说，她是约翰·霍普金斯应用物理实验室的DART任务系统工程师。 12."Astronomers will be able to compare observations from Earth-based telescopes before and after DART's kinetic impact to determine how much the orbital period of Dimorphos changed," said Tom Statler, DART program scientist at NASA Headquarters, in a statement. 美国航空航天总部DART项目科学家汤姆·斯塔特勒在一份声明中说:“天文学家将能够比较DART运动撞击前后地球望远镜的观测结果，以确定双形态星的轨道周期改变了多少。”  13."That's the key measurement that will tell us how the asteroid responded to our deflection effort." “这是关键的测量，它将告诉我们，小行星如何对我们的偏转操作做出反应。”   问题 |
