美国宇航局近日宣布,计划于2018年发射“太阳探测器”,探测器将在距离太阳表面近700万公里的外大气层轨道,观测日冕的活动。这将是NASA第一个飞入日冕的探测器,也是人类首次近距离接触太阳。 A US spacecraft set to launch next year will make a series of uNPRecedented dives into the sun’s scorching atmosphere to see how the star works and what can be done to better predict space weather events on Earth, scientists said on Wednesday. 科学家31日表示,美国计划在明年发射“太阳探测器”,对太阳灼热的大气层进行一系列史无前例的探索,以观测太阳的工作原理,以及如何才能更好地预测地球上发生的空间天气事件。 The Parker Solar Probe will have to survive temperatures as high as 2,500 Fahrenheit (1,371 Celsius), impacts by supersonic particles and powerful radiation as it circles as close as 4 million miles (7 million km) to the sun. 帕克太阳探测器将能够承受2500华氏度(约合1371摄氏度)的高温,以及超音速粒子和强大辐射的影响。它将在距离太阳近达400万英里(约合700万公里)的轨道上运行。 |
