Consequently, antimatter requirements are much lower than those of pure-antimatter systems.
However, there are several technical hurdles to be overcome before an antimatter rocket can be built.
All of those missions could be performed by fusion or antimatter rockets with a mass ratio of 5:1 or less.
The principle is simple: an equal mixture of matter and antimatter provides the highest energy density of any known propellant.
Even with the improved antiproton production and storage capacities expected soon, this amount of antimatter is beyond our reach.
The first is that antimatter does not exist in significant amounts in nature, at least, not anywhere near this solar system.
The main mechanism for heating the liquid droplet is antimatter-induced fission fragments which have a range of 45 mm in the droplet.
I shall argue that the acceleration is a consequence of the excess of matter over antimatter in the universe.
