[漢羅] JWST 太空望遠鏡 當咧去 L2 點 ê 路-lih

這張縮時攝影圖內底,有 JWST 太空望遠鏡 tī 天星滿滿 ê 夜空咧行,這馬拄 ùi 獵戶座頭前行過。 伊飛過月球了後,繼續 tùi 伊 ê 終點飛去。 這張是 tī 12 月 28 號翕 ê。 這个縮時攝影是每 10 分鐘翕一張,攏總翕 12 張。 Kā in 對予齊齊了後,閣疊一張有足濟背景星 ê 深空彩色相片,才產生這張動畫。 JWST 太空望遠鏡 12 月 25 發射了後過 2 工半,to̍h 已經飛超過月球軌道 ê 懸度矣。 紲落來伊會 ùi 地球 ê 重力脊 飛到踅 L2 點 ê 暈輪軌道。 L2 點 是 地球-太陽 系統 ê Lagrange 點 ê 其中一點。 Lagrange 點 tī 太空中是一个足方便 ê 所在。 假設太空中有一粒大天體(比論講地球)踅另外一粒大天體(比論講太陽)leh 行,Lagrange 點 to̍h 是這个系統內底 引力 kah 向心力平衡 ê 所在。 Tī 遮 ê 物件會 kah 這兩粒大天體做伙行。 所以,若是有一个質量較細 ê 物件,比論講太空船,to̍h 較愛留踮這位。 L2 點是 5 个 Lagrange 點 ê 其中一點。 伊 tī 地球-太陽 ê 連線頂懸,差不多離地球 150 萬公里遠 ê 所在。 JWST 太空望遠鏡會 tī 明年 1 月 23 飛到 L2 點,這 ê 時陣已經是發射了後 ê 第 29 工矣。 伊這馬已經離開地球表面重力範圍。 你嘛會當 tī 線頂追蹤伊 ê 進度,看伊複雜 ê 安搭過程

[English] JWST on the Road to L2

This timelapse gif tracks the James Webb Space Telescope as it streaks across the stars of Orion on its journey to a destination beyond the Moon. Recorded on December 28, 12 consecutive exposures each 10 minutes long were aligned and combined with a deep color image of the background stars to create the animation. About 2.5 days after its December 25 launch, JWST cruised past the altitude of the Moon’s orbit as it climbed the gravity ridge from Earth to reach a halo orbit around L2, an Earth-Sun Lagrange point. Lagrange points are convenient locations in space where the gravitational attraction of one massive body (Earth) orbiting another massive body (Sun) is in balance with the centripetal force needed to move along with them. So much smaller masses, like spacecraft, will tend to stay there. One of 5 Lagrange points, L2 is about 1.5 million kilometers from Earth directly along the Earth-Sun line. JWST will arrive at L2 on January 23, 29 days after launch. While relaxing in Earth’s surface gravity you can follow its progress and complicated deployment online.
