@edgarblythe,
If we could increase the space vehicles acceleration by one lousy meter^2 per second per minute, wed be there in less than 10 days earth time. to do that, we woud need to send up and orbit a big enough fuel tank to make the 15 x 1440 ) changs in acceleration. this tank, filled, would be a fuel feed for the vehicle compound. OOR we could make the vehicke reaklly small so it could be fueled by a solar sail powered ionic engine that could do the same thing.
