Perijove 16 :木星經過
Perijove 16: Passing Jupiter

觀看朱諾號飛越木星。 美國國家航空航天局(NASA)的機器人太空飛行器朱諾號(Juno)正在繼續進行為期一個月的環繞太陽系最大行星的高延時軌道飛行。 這段影片來自第 16 周,這是朱諾號自 2016 年年中抵達木星以來第 16 次經過木星附近。每次環行都會經過木星雲頂稍有不同的部分附近。 這段彩色增強影片是由 21 張朱諾相機靜態影像數字合成的,從而產生了 125 倍的延時效果。影片開始時,木星正在上升,朱諾號從北面接近木星。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。 隨著朱諾號的遠離,引人注目的海豚狀雲層清晰可見。 近景過後,木星向遠處退去,此時木星南部上空出現了不尋常的雲層。 為了獲取所需的科學資料,朱諾號俯衝到如此接近木星的地方,以至於它的儀器暴露在非常高的輻射水平下。
原文:Watch Juno zoom past Jupiter. NASA's robotic spacecraft Juno is continuing on its now month-long, highly-elongated orbits around our Solar System's largest planet. The featured video is from perijove 16, the sixteenth time that Juno passed near Jupiter since it arrived in mid-2016. Each perijove passes near a slightly different part of Jupiter's cloud tops. This color-enhanced video has been digitally composed from 21 JunoCam still images, resulting in a 125-fold time-lapse. 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. As Juno moves away, the remarkable dolphin-shaped cloud is visible. After the perijove, Jupiter recedes into the distance, now 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.
