Conceptual Rocket Propulsion Systems

Rocket engines of today are insufficient for any type of human travel in our own solar system. Humans have yet to ever go beyond our own moon, just an inch away in the ocean of our solar system. This is due partly because of the sheer time it takes to travel using present-day technology. Currently, NASA is working on many types of propulsion systems for tomorrow. Of these, matter-antimatter, nuclear fusion, and light propulsion are the most intriguing.
Of the three, antimatter propulsion would generate the most energy. When antimatter comes into contact with normal matter, both particles are completely annihilated, releasing pure energy and shooting off radiation at the speed of light.…
