Wow, that's really cool. It looks like a huge step forward in extraterrestrial propulsion technology. I'm really looking forward to seeing how this plays out.

Don't hold your breath. They made a gas plasma with a kind of microwave oven, but that's a very very very long way from a fusion reaction. Also this happened 13 years ago.

The near future is ion propulsion. They're talking 1 month to get to mars using an ion thruster. It has extremely low average thrust, but extremely high specific impulse. An average spaceship would accelerate 0-60mph in four days using ion drives from a decade ago. The speed boundary of current liquid fuel rockets is nearly 18000mph. The theoretical limit of an ion motor is 200,000mph.
