Great news but i dont believe we will succeed in our ventures to other planets until we learn to look after the one we have.
Sorry to get all ethereal in my view, im not taking anything away from this development in technology, just wanted to voice my heartfelt opinion.
The major push in advanced electric propulsion at this time is for the deployment of large plasma thrusters, with ever increasing power units and cost. Imagine instead a system where large power units are placed permanently in orbit around critical regions of a planet. With a beamed plasma system, spacecraft can be pushed or pulled to perform orbital transfers around the planet or accelerated to other planets at essentially the cost of a sub-orbital mission.

AN EXTRAORDINARY "hyperspace" engine that could make interstellar space travel a reality by flying into other dimensions is being investigated by the United States government.
The hypothetical device, which has been outlined in principle but is based on a controversial theory about the fabric of the universe, could potentially allow a spacecraft to travel to Mars in three hours and journey to a star 11 light years away in just 80 days, according to a report in today's New Scientist magazine.
The theoretical engine works by creating an intense magnetic field that, according to ideas first developed by the late scientist Burkhard Heim in the 1950s, would produce a gravitational field and result in thrust for a spacecraft.
Also, if a large enough magnetic field was created, the craft would slip into a different dimension, where the speed of light is faster, allowing incredible speeds to be reached. Switching off the magnetic field would result in the engine reappearing in our current dimension.
despite the danger, both superpowers have shot nuclear reactors into space - the Russians with relative frequency - and both are tinkering with new types of reactors. The Soviet Union has launched 18 nuclear-powered spy satellites. The United States in 1965 launched one reactor, which still circles the earth, and the Defense Department is currently considering a return to the business of boosting reactors into orbit.

As you can see a nuclear device may not even be needed , solar may provide the power enroute

I agree. So long as children are needlessly starving to death, and dying of preventable water-born diseases, humanity should not be going anywhere.

Finallyyyyyyyyyy, enough of Mars already
let's see some ground images of Jupiter and Saturn now
Jupiter and Saturn have no "ground".
You did know that, right?

With the rate we are breeding and over populating this tiny rock, we better hurry up and get out there to find new worlds to live on

Do you realize what will happen when people have no where left to run?
Taking care of the planet will not be on their priority list at all.
You'd better consider what it would mean to get resource extraction and industrial pollutants off the planet, if you want to conserve it over time.

Read carefully. Sure, the plasma engine uses less propellant, but the propellant they use (argon) is not the energy source, unlike propellants used in chemical rockets. This is exactly the source of difference in propellant mass! Pretty obvious, actually.
Now, the plasma engine will need energy to operate, so they will have to carry an energy source at least as heavy as conventional rockets.
Case closed.
