I don't fully understand how the craft will be able to head toward Venus, against the solar wind. With no medium to push against or any other means or propulsion, I don't see how the craft can ever head upwind. A sail boat has water to "push off" of and can heading upwind at an angle but this craft does not ya know? Anyone know the physics behind this?
