Re: Z-Pinch Renaissance

not my work but relevant underlined comments are mine. Consider a 1,000 ton spacecraft with a 10,000 km/s exhaust velocity and an acceleration of 0.722 m/s/s. For a 1 AU trip at constant acceleration, flipping at the midpoint, it will take 10.5 days and consume 66 tons of propellant/fuel. Now let's ...

Re: Z-Pinch Renaissance

These are very rough numbers ( with huge assumptions ) but your looking at 60 days will get about to Jupiter. 90 days will get you to Saturn. with a flip and slowdown because what is the point of going without stopping for a visit.
