Traditional materials may lack the necessary properties for optimal performance in space. Nanomaterials provide several advantages:
Lightweight: The reduced mass of nanomaterials like graphene minimizes the overall weight of the spacecraft, which is crucial for achieving high velocities. High Strength: Nanomaterials offer superior mechanical strength, ensuring the sails can withstand the harsh conditions of space. Reflectivity: Materials like metallic nanofilms have high reflectivity, which is essential for maximizing the radiation pressure from the Sun.
