美國太空探索公司SpaceX一枚獵鷹9號火箭殘骸預計於週三撞擊月球,撞擊威力相當於3噸黃色炸藥,將在月面留下坑洞。
美國太空探索公司SpaceX一枚獵鷹9號火箭殘骸,預計於週三(5日)以時速超過5000英里撞擊月球。這塊重約4500公斤的火箭上節將撞擊月球西北側,威力相當於3噸黃色炸藥,為已知第二起廢棄火箭意外撞月事件。
AI-generated summary
獵鷹9號火箭於2025年1月載送月球著陸器及科學儀器升空,任務完成後火箭上節持續在太空漂浮。
美國太空探索公司SpaceX一枚獵鷹9號(Falcon 9)火箭的部分殘骸,預計將於週三(5日)以時速超過5000英里的速度撞上月球,撞擊威力相當於3噸黃色炸藥(TNT),並在月球表面留下坑洞。
綜合外媒報導,這塊殘骸是獵鷹9號火箭的上節,長約12公尺、重約4500公斤,大小相當於一棟5層樓建築。該火箭於2025年1月載送兩具月球著陸器及科學儀器升空,完成任務後,火箭上節便持續在太空漂浮,SpaceX也無法阻止它撞向月球。
獨立天文學家、太空物體追蹤軟體開發者葛雷(Bill Gray)推算,火箭殘骸將於美東時間5日凌晨2時34分(台灣時間5日下午2時34分),以超過時速5000英里(約8047公里)的速度,撞上月球西北側、愛因斯坦環形山(Einstein Crater)附近。
科學家預估,火箭殘骸的撞擊威力相當於3噸黃色炸藥,撞擊當下預計會產生短暫閃光,並將岩石與塵埃拋向太空。研究團隊估計,超過100萬公斤碎屑可能被向上拋出,之後大部分仍會落回月球表面,可能留下直徑約27公尺,深約5公尺的坑洞。
人造物體撞擊月球並非首次,過去已有多國太空載具為研究或任務需求刻意撞月;2022年,中國火箭殘骸也曾意外撞上月球背面。這次預計將是已知第二起廢棄火箭意外撞月事件。

French President Emmanuel Macron has urged Europe to develop an independent crewed space flight capability within ten years. The call, made at a Paris space summit, aligns with European Space Agency chief Josef Aschbacher's push for increased resources and autonomy.

China postponed its Chang'e-7 lunar mission after failing to meet launch requirements, rolling the rocket back to its assembly building. Analysts noted the delay could temporarily ease political and media pressure on NASA.

NASA's mission to rescue the Swift Observatory failed. The commissioned Katalyst unmanned spacecraft experienced a technical problem and spun out of control. NASA announced that it had canceled the rescue. It is expected that the Swift Observatory will naturally fall into the Earth's atmosphere and burn up later this year.

Independent trackers debate two unconfirmed explanations—a YF-100 engine anomaly or a structural failure near Max-Q—following a rocket break-up 85 seconds after launch.

China suffered a rare rocket failure as an unmanned Long March 7A exploded less than 90 seconds after lifting off from the Wenchang Space Launch Site, destroying the ChinaSat-4B communications satellite.

Chinese space scientists have outlined a lunar exploration concept featuring three astronauts working alongside intelligent machines, including robot dogs and a pressurized rover.
