Would be nice, right. A guy named Philip Lubin has been working on directed energy/photonic propulsion - which is a fancy way of saying you put a big sail on your spaceship and fire a laser at it.
The challenge is slowing down the other end. That's the part we don't have worked out yet. Of course, we might be able to send robots to Mars the slow way and have them construct a slow down laser in Martian orbit.
But for further afield, we need to work this one out, especially as lightsail propulsion might be how we get to the stars.
