Historically, spacecraft have followed trajectories that took between six and nine months to reach Mars, using traditional chemical propulsion on roughly Hohmann transfers. It is commonly believed that advances in propulsion technology, such as nuclear thermal or VASIMR, are necessary to reduce that transit time. In this paper, we show the feasibility of transit to Mars using the SpaceX Starship taking 90 days. We outline two trajectories that reduce each transit to between 90 and 104 days each way. These trajectories are within NASA career radiation limits, while 180-day trajectories are not.
从历史上看，航天器沿着传统化学推进方式进行大致霍曼转移轨道，需要六到九个月才能抵达火星。人们普遍认为，推进技术的进步，如核热推进或可变比冲磁等离子体推进（VASIMR），对于缩短这段航行时间是必要的。在本文中，我们展示了使用SpaceX星际飞船90天抵达火星的可行性。我们概述了两条轨道，每条轨道可将单程航行时间缩短至90至104天。这些轨道处于美国国家航空航天局（NASA）职业辐射限制范围内，而180天的轨道则不在此范围内。
