View Full Version : Comparing various reaction masses...

A lot has been discussed about various reaction masses, including hydrogen, boron (boronite), and others.

If we allow for any energy source, of any intensity (temperature) as well as any power (J/s), what's the best reaction mass for blast-off through LOE? LOE to upper orbits? Long haul (distance planets) or really long haul (to another system)?

Most importantly, why?
