NASA's New Solar Sail Successfully Unfurls and Begins Testing

The Advanced Composite Solar Sail System is tumbling as expected, with ongoing evaluations to stabilize and optimize its performance.

NASA's solar sail, launched in April, has deployed from a CubeSat and is currently tumbling in space.
The sail uses sunlight for propulsion, aiming to reduce mission costs and enable efficient deep space exploration.
Initial observations confirm the sail's deployment and reflectivity, making it visible in the night sky.
The tumbling motion was planned, and NASA will stabilize the spacecraft after analyzing the sail and boom performance.
Public can track the sail's progress and share sightings via the NASA app and social media.
