Naturally Earth isn't as heavy as Jupiter so instead of doing the whole shift on one pass you make six passes by the Earth, one every six months as the orbits cross, and wind up going the other way around the sun three years after launch. The actual shape of the impactor is likely to flat with solar cell wings that are tilted with motors to get sunlight to gently twist the impactor around to the correct facing. -HJC

Those are going to be some mighty low amp motors to run on that amount of power. Pat
From: David E. Powell on 9 Apr 2010 01:02 I always dug the idea of a towed launch myself. For SSTO the Scramjet/ Scramrocket seems the best idea. Use the natural air up until you can't anymore, and get a really good speed up, then shoot in some oxidizer for the final part of the insertion.
