給航海家1號

一光日的家書
接近絕對溫度的鄉愁

人類依舊相愛爭吵

文明沒變

地球仍在旋轉

只是多了幾個AI

   ——人類歷史上最孤獨沉默的信使“航海家1號”(Voyager 1)，預計將在2026年11月成為首個抵達距離地球1光日(光走一天的距離)的太空船。Voyager 1 1977年發射，是目前唯一已經飛出太陽圈的人類飛行器，距離地球158億英里，是距離地球最遠的太空船。

      To Voyager 1

A family letter one light day away

Homesickness nearing absolute zero

Humans still love and quarrel

Civilization unchanged

Earth keeps turning

Only with a few more AIs added

     ——The loneliest and most silent messenger in human history，Voyager 1 is expected to become the first spacecraft to reach a distance of one light day from Earth in November 2026. Launched in 1977, it is currently the only human-made object to have exited the heliosphere, now about 15.8 billion miles from Earth and the most distant spacecraft humanity has ever sent.
