Small Solar Power Sail Demonstrator 'IKAROS': Confirmation of Photon Acceleration

2010 · Agency-reported flight demonstration

Measured evidence

What this work contributes

Reports orbit-determined solar-photon acceleration following sail deployment. JAXA gives an estimated sunlight-pressure thrust of 1.12 mN, providing a real example of travel without consuming onboard propellant for that force.

Where the evidence stops

Solar sailing exchanges momentum with sunlight; it is propellant-free propulsion, not force-free motion. Performance depends on sail properties, area, orientation, and illumination.
