This drive would significantly reduce the risk to humans, so it definitely lowers the blue curve on that graph. Whether or not the difference buys us enough time, I don't know. It will probably be a few years before this technology is tested in space, and at least several more before it could be part of a manned-mission to Mars. Those robots will change a lot in the next decade.
