人類時隔半世紀再啟繞月任務　重返月球關鍵一步

Artemis II Successfully Launched
First Crewed Lunar Flyby in Decades Marks Key Step Toward Moon Return

NASA「阿提米絲2號」（Artemis II）任務於美東時間1日晚間19時35分（台灣時間2日上午7時35分）自佛羅里達州升空，正式展開為期10天的載人繞月任務。這是繼Apollo 17於1972年之後，人類再度執行繞月飛行，象徵重返月球計畫的重要里程碑。

NASA’s Artemis II mission lifted off at 7:35 p.m. EDT on the 1st (7:35 a.m. Taiwan time on the 2nd), launching a 10-day crewed lunar flyby. This marks humanity’s first return to lunar orbit since Apollo 17 in 1972, representing a major milestone in the effort to return to the Moon.

SLS搭配獵戶座　4太空人展開10天繞月任務

SLS and Orion Carry Four Astronauts on 10-Day Lunar Mission

本次任務由「太空發射系統」（SLS）火箭與「獵戶座」（Orion）太空船組成，自Kennedy Space Center Launch Complex 39B發射升空，在固體火箭助推器與主核心火箭分離後，約於發射8分鐘後進入太空軌道。

The mission utilizes SLS rocket and Orion spacecraft, launching from Launch Complex 39B at Kennedy Space Center in Florida. After separating from its solid rocket boosters and core stage, the spacecraft entered space approximately eight minutes after liftoff.

「獵戶座」太空船隨後透過臨時低溫推進段（ICPS）進行軌道調整，在近地點完成推進噴射並展開4組太陽能板，預計完成系統檢測後，正式進入前往月球的飛行軌道。

The Orion spacecraft then used its Interim Cryogenic Propulsion Stage (ICPS) to perform orbital adjustments, executing burns at perigee and deploying four solar arrays. Following system checks, it is set to proceed on its trajectory toward the Moon.

國際太空人團隊執行　飛越月背蒐集關鍵數據

International Crew to Fly Past Lunar Far Side and Gather Key Data

根據航太媒體SpaceNews報導，本次任務由美國太空人Reid Wiseman、Victor Glover、Christina Koch，以及加拿大太空人Jeremy Hansen共同執行。

According to SpaceNews, the mission crew includes NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen.

任務期間，「獵戶座」預計於第6天飛越月球背面，執行觀測與影像拍攝任務，為後續載人登月任務蒐集地表資料；之後將利用月球重力進行「引力彈弓」返回地球，最終降落於加州外海，由美國海軍進行回收作業。

During the mission, Orion is expected to fly past the far side of the Moon on day six, capturing imagery and conducting observations to support future crewed landing missions. It will then use a gravity assist maneuver to return to Earth, splashing down in the Pacific Ocean off California, where it will be recovered by the U.S. Navy.

最遠距離挑戰　為2028登月任務鋪路

Record-Breaking Distance Sets Stage for 2028 Lunar Landing

若任務順利，太空人將飛抵距地球約40萬公里處，有望刷新自Apollo 13以來人類最遠飛行距離紀錄。整體航程約68.5萬哩（約110萬公里），將為後續任務奠定基礎。

If successful, the crew will travel to a distance of approximately 400,000 kilometers from Earth, potentially setting a new record for the farthest human spaceflight since Apollo 13. The total mission distance will reach about 685,000 miles (1.1 million kilometers), laying the groundwork for future missions.

未來，Artemis III預計於2027年執行登月艙對接測試，而Artemis IV則規劃於2028年實現載人登月，「阿提米絲2號」的成功，將成為重返月球計畫的重要技術基石。

Looking ahead, Artemis III is planned for 2027 to conduct lunar lander docking tests, followed by Artemis IV in 2028, which aims to achieve a crewed lunar landing. The success of Artemis II will serve as a critical technological foundation for humanity’s return to the Moon.
