🔍Introduction

引言

2025 was an extraordinary year of engineering achievement for NASA's Voyager 1 spacecraft, most notably the successful restart of thrusters that had been dormant for 21 years, ensuring humanity's most distant space messenger could continue transmitting unique scientific data from interstellar space. This remote repair operation on the 47-year-old spacecraft represents one of the most impressive engineering feats in space exploration history.

2025 年對 NASA 的 Voyager 1 太空船來說是一個非凡的工程成就年，最重要的是成功重新啟動了休眠 21 年的推進器，確保人類最遠的太空使者能夠繼續從星際空間傳輸獨特的科學資料。這次在 47 歲太空船上完成的遠程修復作業，代表了太空探索史上最令人印象深刻的工程壯舉之一。

📊Historic Thruster Revival Breakthrough

歷史性推進器復活突破

On May 14, 2025, NASA announced the successful restart of Voyager 1's main roll thrusters, which had been considered permanently inoperative since 2004 （來源）.

2025 年 5 月 14 日，NASA 宣布成功重新啟動 Voyager 1 的主滾轉推進器，這些推進器自 2004 年以來一直被認為永久失效。
