美国国家航空航天局深空探测船朱诺进入环绕星轨道后向地球传送了第一张木星的照片。
美国航天局星期二公布的第一张照片显示了木星四颗最大卫星中的三颗卫星，分别是埃欧、欧罗巴和蓋尼米德。
朱诺在经历了5年、28亿公里的旅程后上星期进入木星轨道。地面控制人员当时特意将朱诺上的摄像机和其它设备一并关闭，防止这些设备在朱诺穿过木星辐射带时受到损伤。
朱诺探测船会在接下来的20个月里研究这颗离太阳距离排行第五、体积最大的行星，帮助科学家探索太阳系的起源，寻找木星大气层底下是否存在固体表面的证据。
朱诺摄像机预期下个月底将在离木星最近的时候拍摄传送第一批高清图片。
NASA'S deep space probe Juno has sent back its first image of the planet Jupiter since arriving at the interstellar gas giant.
The U.S. space agency released a picture Tuesday showing Jupiter surrounded by three of its four largest moons — Io, Europa and Ganymeade.
Juno entered orbit around Jupiter last week after a five-year, 2.8 billion kilometer journey. Ground controllers deliberately kept the probe's camera — dubbed the JunoCam — and other instruments shut down as a precaution as Juno passed through Jupiter's extreme radiation environment.
The probe will spend the next 20 months studying the fifth — and biggest — planet in our solar system, to help scientists determine the foundations of our solar system, and to search for signs of a solid surface beneath its cloud-covered atmosphere.
The JunoCam is expected to send its first high-resolution images of Jupiter late next month, when the probe makes its next closest pass across the planet.
