新技術有望將前往天王星的航程縮短一半
New Tech Could Cut Travel Time to Uranus in Half
探索外太陽系傳統上是一場耐力的考驗，通常需要超過 13 年才能抵達冰巨星天王星。
Exploring the outer solar system has traditionally been a game of patience, often taking over 13 years to reach the ice giant Uranus.
然而，來自麻省理工學院的研究人員提出了一個革命性的轉變。
However, researchers from MIT suggest a revolutionary shift.
藉由利用 SpaceX 的星艦，科學家提出了一種新的任務架構，可將航行時間大幅縮短至僅 6.5 年。
By utilizing [SpaceX’s Starship|Entity], scientists propose a new mission architecture that could slash transit time to just 6.5 years.
這種方法摒棄了依賴緩慢的多行星重力助推的傳統技術，轉而採用一種高能量設計，利用軌道加油來實現直接飛行軌跡。
This approach moves away from legacy methods, which rely on slow, multi-planet gravity assists.
此外，太空船可以採用氣動煞車技術，利用其隔熱盾在天王星大氣層中進行減速。
Instead, this high-energy design uses in-orbit refueling to power a direct trajectory.
研究身為行星科學優先目標的天王星，對於了解冰巨星的形成及其獨特的行星磁場至關重要。
Furthermore, the spacecraft could employ aerobraking, using its heat shield to slow down in the Uranian atmosphere.
儘管軌道加油等技術尚未經實證，但這項提案預示了太空探索的變革。
Studying Uranus, a priority destination for planetary science, is crucial for understanding ice giant formation and unique planetary magnetic fields.
如果成功，我們很快就能解開隱藏在太陽系深處的秘密。
Moving from decades-long wait times to a mission achievable within a career timeframe makes exploring the outer planets more feasible than ever.
