NASA SPACECRAFT ARRIVES AT JUPITER
NASA的航天器抵达木星
It only took five years and 1.7 billion miles, but in July NASA’s Juno spacecraft completed a daredevil maneuver to get into orbit around the largest planet in our solar system. Launched in August 2011, Juno is the first human-made object to orbit Jupiter since the end of the Galileo mission in 2003. The solar-powered spacecraft is designed to study the giant planet’s structure and intense magnetic field.
NASA的“朱诺”号航天器仅耗时5年,走行17亿英里,在7月份完成了一次英勇的行动进入了围绕太阳系中最大行星运行的轨道。“朱诺”号于2011年8月发射,是2003年“伽利略”号任务结束后第一个绕木星运行的人造物体,它由太阳能提供动力,被设计用来研究木星结构和强磁场。
But first, Juno had to survive its long cruise through space and then a harrowing trip through the planet’s punishing radiation belts. On July 4, the pinwheel-like spacecraft began spinning faster, tumbling into position for a successful orbit. In the following weeks, it sent back stunning new images and fresh reams of data.
但“朱诺”号首先要经历穿越太空的长期航行,然后完成穿越木星强辐射带的艰难旅程。7月4日,这个像纸风车的航天器旋转速度开始加快,进入指定位置成功开始绕行。在接下来的几周,它发回了令人惊叹的新图像和大量新数据。
