Could Human Reach Mars???????

Rocket powered by nuclear fusion could send man to Mars

Human travel to space has been a long un achievable task in the olden days. But now man has conquered the space. As the next step in that man is going to conquer our neighboring planet also. Astronauts are at the step closer to reach our neighboring planet “Mars” by the using rockets propelled by nuclear fusion, the energy which powers the sun and the stars.

University of  Washington researchers and scientists at a Remond-based space propulsion company are building components of a fusion powered rocket to eradicate the existing hurdles for deep space travel such as long times in transit, cost and health risks. “Using existing rocket fuels, it’s impossible for humans to go beyond Earth so we are hoping to give a much more powerful source of energy which would lead to interplanetary travel as commonplace” said researcher John Slough.

With the existing technology of chemical rocket fuel it will take nearly 4 years to reach Mars for human being also it is very expensive. But with the nuclear fusion propelling rocket we can reach Mars with in 90 days with minimum cost. The fusion needed to power a rocket is also very small 

i.e. 1 gallon of rocket fuel = a small grain of this material.

PRINCIPLE: The plasma (blue) is injected into the rocket nozzle. Lithium (red) metal rings then collapse at great force around plasma, compressing it to fusion conditions. The sudden release of fusion energy vaporizes and ionizes the lithium in the magnetic nozzle, causing it to eject and power the rocket forward.

Normally nuclear fusion reaction is annoying one, everyone will get afraid to travel in a fusion reacting rocket. But the specialty of this rocket is it uses 1 billion factor reduced fusion energy from hydrogen bomb, too little to create explosion. Also it uses magnetic field to contain fusion fuel so it guide the passengers and spacecraft in a safe mode.

Note: This technology is right now at the stage of laboratory testing
