Of course a ship could be assembled in space to take care of the launch problem, and it could carry a lander as was used on the moon mission so that the lander wouldn't need to be large.
And throw on some solar sails that also collect solar power.
But if this turns out to be a viable thrust and can be scaled up by technological advances, this could be coolest.
BTW, rather than trying to work on finding a Planet B, I think the future of Man In Space is in space, not necessarily on the surface of various terraformed planets. If we can communicate through our Earth's van Allen belts to the rovers on Mars, why can't a spacecraft create it's own van Allen belts to shield itself from the radiation problems?
