獲得許可 SpaceX「星艦」將進行第二次試射

太空探索技術公司 SpaceX 宣佈,將於星期六 18 日美東時間上午 8 點,嘗試第二次發射「星艦」Starship。

在獲得了第二次飛行發射許可後,SpaceX 原定於17日發射「星艦」,但總裁馬斯克在社交媒體上 X 發文表示,由於「星艦」需要更換一個格柵翅片執行器(Grid fin actuator),因此發射被推遲到 18 日。

此次發射標誌著 SpaceX 第二次嘗試將「星艦」飛船送入天空軌道。太空船屆時將從德州發射,與助推器分離後繞地球飛行,並在升空約 1.5 小時後降落在夏威夷海岸附近的太平洋區域。

據悉,太空總署計劃在 2025 年利用「星艦」將「阿提米斯」登月計畫的太空人送上月球,但在載人飛行前需要進行多次試飛 。

SpaceX 於今年 4 月首次發射「星艦」,但在發射後,33 具主引擎有 7 具沒有啟動,在飛行期間兩級火箭也未能分離,4 分鐘後自行引爆。這次升空也損壞了發射台的部分設施。SpaceX 隨後對「星艦」、發射塔和發射台系統進行了改進。

根據 SpaceX 網站介紹,「星艦」是迄今全球體積最大、推力最強的運載火箭,總高度約 120 米,直徑約 9 公尺。火箭由兩部分組成,底部是第一級「超級重型」助推器,頂部是太空船船艙,可重複使用。
