Outer space is humanity's final frontier with our species yet to leave the moon. But efforts to build colonies on the moon and beyond Mars have begun. The main problem with traveling to other planets is that it can take decades without a new propulsion system.
Pulsar Fusion a UK firm announced the development of a nuclear fusion engine for the UK Space Agency. With a nuclear fusion engine, the temperature inside the engine can reach the same temperature as the surface of the sun, which is able to provide rocket thrust that reaches a speed of 500,0000 km/h. In theory the trip to Pluto which should take 10 years is shortened to around 4 years only.
Rolls Royce has previously shown a mini nuclear reactor for use in space built for the UK Space Agency. At the same time the United States through DARPA and NASA are also interested in doing the same with the DRACO engine for a trip to Mars.
Nuclear fusion has already been successfully performed by scientists from Lawrence Livermore National Laboratory this year. It is seen as a clean energy source of the future because it leaves no nuclear waste. Now it may be the stepping stone to realizing the human species' dream of traveling into space like a work of science fiction
