Final answer:
Solar sail crafts can be propelled using particles within the solar wind.
Step-by-step explanation:
The statement is true.
Solar sail crafts can be propelled using particles within the solar wind. When the solar wind particles collide with the sail, they transfer momentum to it, causing it to accelerate.
This concept is based on the conservation of momentum and is similar to how a sail on a boat works, but instead of wind, solar radiation is used as the driving force.
