A New NASA Design Turbocharges Nuclear Spacecraft
· 2026-08-26 · 原文 · 证据态 未学
Summary NASA and industry engineers propose a synchronal bimodal nuclear rocket (S‑BNR) to dramatically cut transit times to destinations around the solar system, such as Mars, by combining nuclear thermal and electric propulsion. S‑BNR uses a single reactor with two independent fluid loops and correspondingly optimized fuel zones, eliminating complex mode-switching valves while providing both high thrust and continuous electric power. Major challenges include developing fuel elements that integrate well together, ground testing, nuclear launch safety, and multi-agency collaboration to mature the technology from modeling to in‑space demonstrations. The biggest threat to any crewed expedition to Mars is time . NASA’s shortest blueprint for sending people to the Red Planet and back requires
