Faster forms of spacecraft propulsion have been a dream for decades, but now one researcher thinks he has a solid idea. Known as directed energy propulsion, it would involve firing a laser at a tiny spacecraft to speed it up to a significant fraction of the speed of light, potentially allowing for missions to Mars in less than an hour, rather than the months it takes at the moment. (Of course we couldn't stop and would plough into Mars in a titanic explosion.)
