Perijove 11: Passing Jupiter

木星來了美國國家航空航天局(NASA)的機器人太空飛行器朱諾號(Juno)正在繼續圍繞太陽系最大的行星進行高度拉長的軌道飛行。 這段影片來自 2018 年初的第 11 周,這是朱諾號自 2016 年年中抵達木星以來第 11 次經過木星附近。 這部延時拍攝、色彩增強的影片涵蓋約四個小時,在 36 張 JunoCam 影像之間切換。影片開始時,木星正在上升,朱諾從北面接近木星。當朱諾號到達最近的視角時--從木星雲頂上空約 3500 公里處--太空飛行器捕捉到了這顆偉大行星的巨大細節。朱諾號經過環繞木星的光帶和暗雲帶,以及無數漩渦狀圓形風暴,其中許多風暴比地球上的颶風還要大。 在近交點之後,木星逐漸向遠方退去,然後顯示出木星南部出現的不尋常雲層。 為了獲取所需的科學資料,"朱諾 "號俯衝到如此接近木星的位置,以至於它的儀器暴露在非常高的輻射之下。
原文:Here comes Jupiter. NASA's robotic spacecraft Juno is continuing on its highly elongated orbits around our Solar System's largest planet. The featured video is from perijove 11 in early 2018, the eleventh time Juno passed near Jupiter since it arrived in mid-2016. This time-lapse, color-enhanced movie covers about four hours and morphs between 36 JunoCam images. The video begins with Jupiter rising as Juno approaches from the north. As Juno reaches its closest view -- from about 3,500 kilometers over Jupiter's cloud tops -- the spacecraft captures the great planet in tremendous detail. Juno passes light zones and dark belts of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. After the perijove, Jupiter recedes into the distance, then displaying the unusual clouds that appear over Jupiter's south. To get desired science data, Juno swoops so close to Jupiter that its instruments are exposed to very high levels of radiation.
