Re: The Outer Solar System Can Be Ours!
You are wrong.
VERY small amounts have been spent on new propulsive systems, e.g. VASIMR.
Far amaller amounts than even ONE mission.
A sail would be USELESS in the outer solar system for necessary functions like orbital braking and orbital changes. A system such as VASIMR which needs to be flown DS1 style to ascertain fact vs lab wonder, would be ideal.
