Question:
In spaceflight, reaching high speeds and escaping planetary gravity requires efficient fuel usage and high specific impulse. Explain the advantages and limitations of using nuclear thermal propulsion compared to chemical propulsion for interplanetary missions. Discuss factors such as specific impulse, fuel efficiency, safety, and the impact of each propulsion type on mission planning and payload capacity. How might these considerations differ for a mission to Mars versus a mission to an outer planet like Jupiter?
