wow. finding what I am looking for for a change :) ok so i don't understand exactly how it wrks but nuclear has a higher energy density. and while there are many conceptual methods developed it appears that a nuclear thermal rocket would be the method that could be developed the fastest. the...

ah nm. i found that it includes the oxidizer as well.

is the oxidizer included in the propellant or would i need another 8x that mass to get the 450 impulse? only thing i can think of bigger than that would b like a nuclear reactor but that primarily generates heat and thru e=mc^2 it would take a really much bigger amount of mass to generate...

the method of thrust would be combustion as of now. still haven't determined which method would b best. i was thinking 2H2(l) + O2(g) = 2H2O(g). the eventual mass of the object being accelerated by the burning hydrogen would need to include the added mass of the fuel needed to propel it and i...

first off, thanks to any that respond w useful info :) the end answer i need to find on the first topic is how many atoms of hydrogen are required to propel a mass of "x" at an acceleration of 1g in space (assuming no gravitic influence) but i would settle for how to figure out what the fuel...
