Exactly right. That's why Nuclear Propulsion coupled with  3.5 million kilograms of Hydrogen fuel will cut the trip to Mars down to 86 days. Chemical rockets would require twice the fuel.

The equation below proves that Hydrogen is the best Nuclear Rocket fuel!

This kind of Nuclear Thermal rocket fueled by enough liquid hydrogen can beat everything else to Mars.

The Spin Launch vehicle would need to be larger and outfitted with a discharge to orbital reservoir coupling. The vehicle would also need to glide home for refueling and relaunch.


At -252.87°C and 1.013 bar, liquid hydrogen has a density of close to 71 kg/m³ .

The trip time to Mars would be inversely proportional to the kilograms of Liquid Hydrogen available in orbit for the Nuclear Thermal rocket motor. The more Liquid Hydrogen launched to Space, the shorter the trip time to Mars. Two weeks of travel time would be achievable! Fueled by the power from Chinbrazo!

The best approach would be to send uniform propellant tanks through the inside of the Spin Launcher Throw Arm and eject them repeater style, then collect and feed the Nuclear Thermal Mars Rocket from a magazine. This would involve a one way trip for the propellant tanks. We can cut the trip time from 9 months to a fortnight.

200 kg of Hydrogen would require 3 cubic meters of Rocket volume.
