[漢羅] DART：去挵小行星 Dimorphos

人類敢有法度對抗 欲挵著地球 ê 小行星？ 會當！ 大粒 小行星 ê 毀滅性 衝擊，捌 tī 地球 發生過幾若擺，有當時仔會造成地球生物 ê 大滅絕。 為著欲保護地球 tī 未來莫去予小行星 舂著，NASA 昨昏做一个新 ê 行星防衛機制 ê 實驗。 In kā 雙小行星改道實驗 (DART) 機器人太空船 駛去挵 小行星 Dimorphos。 伊是小行星雙星系統內底較細粒彼粒，大細差不多 170 公尺大。 Tī 這支影片 內底，這个衝擊實驗是成功--ê。 理論上，這个實驗若是較早做咧，就算咱用太空船細力 kā 小行星踢一下，嘛有法度 kā 較大粒 ê 小行星 踢離開地球。 咱會當 tī 這支縮時攝影影片內底看著 DART 先飛過倒爿 ê 大粒 小行星 Didymos，紲落來才飛到 細粒小行星 Dimorphos。 是講這支影片 tī DART 挵著小行星 ê 時陣就煞矣。 毋閣 太空船 kah 全球 ê 望遠鏡 監看 Dimorphos 軌道改變 ê 工課 才 拄 開始。

[English] DART: Impact on Asteroid Dimorphos

Could humanity deflect an asteroid headed for Earth? Yes. Deadly impacts from large asteroids have happened before in Earth's past, sometimes causing mass extinctions of life. To help protect our Earth from some potential future impacts, NASA tested a new planetary defense mechanism yesterday by crashing the robotic Double Asteroid Redirection Test (DART) spacecraft into Dimorphos, a small asteroid spanning about 170-meters across. As shown in the featured video, the impact was a success. Ideally, if impacted early enough, even the kick from a small spacecraft can deflect a large asteroid enough to miss the Earth. In the video, DART is seen in a time-lapse video first passing larger Didymos, on the left, and then approaching the smaller Dimorphos. Although the video ends abruptly with DART's crash, observations monitoring the changed orbit of Dimorphos -- from spacecraft and telescopes around the world -- have just begun.
