Proposed Nuclear Engine Could Send Humans to Mars in Just 45 Days

A pioneering concept suggests future crews could reach Mars in as little as 45 days using a nuclear thermal or nuclear electric propulsion system. Engineers claim the design harnesses the immense energy density of nuclear reactions to dramatically cut travel time compared to conventional rockets. Shorter voyages might reduce health risks from cosmic radiation and microgravity. While questions about reactor safety and cost linger, researchers see potential for faster, safer exploration of deep space in the coming decades.
