Origin of how steam rockets can reduce space transport cost by orders of magnitude

Utilizing fission technology to enable rapid and affordable access to any point in the solar system

“…Water can both be electrolyzed and used in chemical propulsion systems or used directly in nuclear steam rockets (Zuppero, 1999). Unfortunately, there are no known in-space reservoirs of relatively pure water in the inner solar system.…”

“…Once water isinthedesired orbit, itcaneither beused directly insteam rockets (Zuppero, 1999) or electrolyzed for use in chemical engines. If orbits are properly chosen and in-space propellant re-supply is used, fast planetary transfers can be accomplished using currently available rocket technology.…”
