美國木星探測船傳回第一張照片

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.美國國家航空航天局深空探測船朱諾進入環繞星軌道後向地球傳送了第一張木星的照片。

美國航天局星期二公佈的第一張照片顯示了木星四顆最大衛星中的三顆衛星，分別是埃歐、歐羅巴和蓋尼米德。

朱諾在經歷了5年、28億公里的旅程後上星期進入木星軌道。地面控制人員當時特意將朱諾上的攝像機和其它設備一併關閉，防止這些設備在朱諾穿過木星輻射帶時受到損傷。

朱諾探測船會在接下來的20個月裏研究這顆離太陽距離排行第五、體積最大的行星，幫助科學家探索太陽系的起源，尋找木星大氣層底下是否存在固體表面的證據。

朱諾攝像機預期下個月底將在離木星最近的時候拍攝傳送第一批高清圖片。
