火星沒有高速公路，卻有里程競爭。金氏世界紀錄報導，美國航太總署（NASA）火星車「毅力號」（Perseverance）在 2026 年 10 月 11 日從耶澤羅隕石坑邊緣的「Lac de Charmes」朝「Idubi」岩區行駛約 91 公尺後，總里程來到 45.22 公里，正式超越「機會號」（Opportunity）保持的 45.16 公里，成為在其他天體上開最遠的車輪機器人。
EN Mars has no highways, but it does have a distance competition. Guinness World Records reported that NASA’s Perseverance rover drove about 91 meters on October 11, 2026, from Lac de Charmes on the edge of Jezero Crater toward the Idubi rock area. Its total distance reached 45.22 kilometers, passing Opportunity’s 45.16 kilometers to become the wheeled robot that has traveled farthest on another world.

機會號花了約十四年才累積那段里程；毅力號登陸以來只用不到一半時間就超車，關鍵不是比較會「踩油門」，而是比較會自己認路。
EN Opportunity took about 14 years to cover its distance. Perseverance passed it in less than half that time after landing. The key is not a faster engine, but a smarter ability to find its own way.

AutoNav：邊開邊想，不用步步等人遙控
火星通訊單程就要十幾分鐘，工程師無法像開遙控車一樣即時操縱。舊款好奇號常要開到視野邊緣就停、拍照、再規劃。毅力號多了視覺計算模組，能在行駛中辨識障礙並修正路線，單次行駛最遠可到約 412 公尺。
EN Radio signals to Mars take many minutes each way, so engineers cannot control a rover in real time like a toy car. Curiosity often has to drive to the edge of its view, stop, take pictures, and plan again. Perseverance has an extra vision computer that can spot obstacles and change its route while driving. A single drive can cover about 412 meters.

2026 年二月，團隊還把原供「機智號」直升機通訊的備用電腦，改造成「火星全球定位」輔助：車載相機拍 360 度地平線，比對衛星地圖，定位誤差可到約 25 公分。
EN In February 2026, the team also reused spare computer hardware originally meant for communication with the Ingenuity helicopter. It now helps with Mars Global Localisation. The rover takes a 360-degree view of the horizon and compares landmarks with satellite maps, finding its position to within about 25 centimeters.

機會號的告別因全球沙塵暴斷電而聞名，毅力號則靠核電池與更強腦力續航。兩者都是地球派人去另一顆行星「走路」的代表作。
EN Opportunity’s mission ended when a planet-wide dust storm cut off its solar power. Perseverance uses a nuclear power source and smarter navigation to keep exploring. Both show how robots from Earth can travel across another planet.

AutoNav 讓每天可規劃的科學目標變多：同樣一個火星日，車能開得更遠，鑽頭與相機就能覆蓋更大區域。里程紀錄表面是數字，背後是生產力。
EN AutoNav can help the team reach more science targets. Traveling farther in a Martian day lets the rover’s cameras and drill explore a wider area. The distance record is not just a number. It also represents more scientific work.

下一個目標：繼續開，繼續採樣
專案經理史蒂夫・李（Steve Lee）說，團隊很興奮能延續 NASA 火星探索傳統，里程還會隨著每個火星日增加。毅力號馬達原保守估計可行駛約 20 公里，現在預期壽命內有機會挑戰 100 公里級距離，讓更多古老岩層進入採樣範圍。
EN Project manager Steve Lee said the team was excited to continue NASA’s tradition of Mars exploration, with the distance record growing each Martian day. The motors were originally rated conservatively for about 20 kilometers. The team now expects them to cover at least 100 kilometers during their lifetime, bringing more ancient rock layers within reach for sampling.

對地球上的我們來說，這則新聞最浪漫的地方或許是：有一台沾滿紅塵的機器人，正安靜地在另一顆行星寫下里程碑——而且紀錄證書，還被拍進地球上的工程複製品合照裡。
EN For people on Earth, there is something moving about a dusty robot quietly making history on another planet. The record certificate was even photographed beside its engineering duplicate back on Earth.

JPL 把證書跟地球上的工程複製品合照，有種溫柔的儀式感。對孩子來說，這是理解「機器人探險家」的入口；對大人來說，則是提醒基礎研發要熬很久，才會在某一天突然超車。
EN JPL’s photo of the certificate and the Earth-based rover is a gentle way to celebrate. For children, it can open a door to the idea of robot explorers. For adults, it is a reminder that basic research can take years before reaching a memorable milestone.
