NASA has successfully deployed its Advanced Composite Solar Sail System which can propel a spacecraft using only power from the sun. The solar sail is now in orbit around Earth, harnessing photons from the Sun to navigate space.
The solar sail, which spans around 860 square feet, operates similarly to a sailboat on Earth, but instead of relying on wind, it uses the pressure exerted by the Sun’s rays for propulsion.
Photons, or particles of light, bounce off the sail’s reflective material, pushing the spacecraft in the desired direction based on the sail’s orientation.
NASA said this approach to space travel holds significant promise for the future of exploration, including “low-cost deep space missions.”
Unlike traditional spacecraft, which are restricted in the distances they can cover by factors like fuel capacity and engine power, space travel with solar sails is limited only by the durability of its materials.
Researchers believe this innovation could be utilized in early-warning satellite systems, space surveillance and enhanced solar observation missions. Additionally, because of the sail’s highly reflective materials, it may be visible from Earth on clear nights, offering a rare opportunity for stargazers to witness this technology in action.
