Why Did NASA Just Launch a Planetary Defense Mission? 為什麼 NASA 剛剛啟動了行星防禦任務?

"Unveiled" Channel on YouTube shows what it is that NASA is worried about. Earth needs defending.

The so-called Double Asteroid Redirection Test (DART) is interesting. Launched in November, 2021, this is one of NASA’s most ambitious planetary defense projects to date. The SpaceX head, Elon Musk, even says it could "avenge the dinosaurs"! This informative video takes a closer look.

The fascinating Double Asteroid Redirection Test (DART) is a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). In September 2022, a certain space probe is set to deliberately crash into the minor-planet moon Dimorphos of the double asteroid Didymos to assess the future potential of a spacecraft impact to deflect an asteroid on a collision course with Earth through a transference of momentum.

DART is a joint project between NASA and the Johns Hopkins Applied Physics Laboratory (APL). It is being administered by NASA's Planetary Defense Coordination Office, and several NASA laboratories and certain offices are providing technical support. International partners, such as the space agencies of European Space Agency (ESA), Italian Space Agency (ASI), and JAXA Japan, are contributing to related or subsequent certain projects. In August 2018, NASA approved the project to start the final design and important assembly phase. The interesting DART spacecraft was successfully launched on 24 November 2021, with collision slated for 26 September 2022 to 2 October 2022. Check the news after the collision to see the results.

YouTube 上的“揭幕”頻道展示了 NASA 所擔心的事情。地球需要保衛。

所謂的雙小行星重定向測試(DART)很有趣。這是美國宇航局迄今為止最雄心勃勃的行星防禦項目之一,於 2021 年 11 月發射升空。 SpaceX 的負責人埃隆馬斯克甚至說它可以“為恐龍報仇”!這個內容豐富的視頻需要仔細看看。

Unveiled 為您提供非凡問題的令人難以置信的答案!

7:41 結論

引人入勝的雙小行星重定向測試 (DART) 是 NASA 的一項太空任務,旨在測試一種行星防禦近地天體 (NEO) 的方法。 2022 年 9 月,某個太空探測器將故意撞擊雙小行星 Didymos 的小行星衛星 Dimorphos,以評估航天器撞擊的未來潛力,通過動量轉移使小行星在與地球碰撞的過程中偏轉。

DART 是 NASA 和約翰霍普金斯應用物理實驗室 (APL) 之間的一個聯合項目。它由 NASA 的行星防禦協調辦公室管理,幾個 NASA 實驗室和某些辦公室正在提供技術支持。國際合作夥伴,例如歐洲航天​​局 (ESA)、意大利航天局 (ASI) 和日本宇宙航空研究開發機構的航天機構,正在為相關或後續的某些項目做出貢獻。 2018 年 8 月,NASA 批准該項目開始最終設計和重要組裝階段。有趣的 DART 飛船於 2021 年 11 月 24 日成功發射,碰撞時間定於 2022 年 9 月 26 日至 2022 年 10 月 2 日。請查看碰撞後的新聞以查看結果。
