How far can we go with chemical rockets?
Summary
Daniel and Kelly explore the limitations of chemical rockets for deep space travel, highlighting their inefficiency and massive fuel requirements. They introduce ion thrusters as a superior alternative that separates energy from propellant, enabling higher velocities with less mass. The episode details how solar power currently limits these thrusters to inner solar system missions, making nuclear-powered ion drives the necessary physics-based solution for reaching Mars and beyond.
