新型核聚變火箭引擎有望大幅縮短前往火星的航程
New nuclear fusion rocket engine could make travel to Mars much faster
想像一下，只需三個月而非七個月就能抵達火星。
Imagine reaching Mars in just three months instead of seven.
總部位於英國的 Pulsar Fusion 公司，正透過研發「直接聚變驅動器」(Direct Fusion Drive)，讓這項夢想更趨近於現實。
A UK-based company, Pulsar Fusion, is pushing this dream closer to reality with its work on a Direct Fusion Drive.
二〇二六年，該團隊在實驗性的 Sunbird 系統中成功實現了「首次電漿」(first plasma) 的里程碑。
In 2026, the team successfully achieved "first plasma" in their experimental Sunbird system.
透過使用強大的磁場來約束離子氣體，他們證實了聚變引擎所需的核心架構是可行的。
By using powerful magnetic fields to confine ionized gas, they are proving that the core architecture needed for a fusion engine is possible.
這些引擎可作為「太空拖船」，在軌道間運送人員，並提供足夠的動力來維持複雜的機載系統。
These engines could serve as "space tugs," ferrying crews between orbits with enough power to sustain complex onboard systems.
科學家必須掌握極端高溫下的電漿約束技術，並創造能承受強烈輻射的材料。
Scientists must master plasma confinement at extreme temperatures and create materials that can withstand intense radiation.
如果科學家能克服這些巨大的工程障礙，這項技術將能從根本上改變太空探索的經濟效益，並讓我們更易於探索太陽系。
If scientists can overcome these immense engineering hurdles, this technology could fundamentally change the economics of space exploration and make our solar system far more accessible.
