"NASA's Innovative Solar Sail Propulsion System Ready for Deep Space Missions"
NASA's solar sail technology has reached Technology Readiness Level 6, making it available for inclusion in mission proposals. The sail, developed over 25 years, is designed to provide precision navigation through space and could enable missions close to the Sun. Solar sails work by reflecting sunlight and offer an efficient, fuel-free propulsion method for uncrewed space missions. The technology has been successfully demonstrated in previous missions, and proposals for its use in upcoming missions are now being sought.
