Japan's Solar Sail Operates Successful in Space

GreenTracker| Japanese scientists are celebrating the successful deployment of their solar sail, Ikaros, a 2100 sq ft membrane launched in space to demonstrate the principle of using sunlight as a simple and efficient means of propulsion and alternative energy. 

The Japan Aerospace Exploration Agency (Jaxa) confirms that the sail is already generating power through the thin-film solar cells embedded in the membrane. This development won’t replace convention propulsion systems in space travel, but they are another step forward into achieving the ultra-lightweight, very fast spacecraft that doesn’t use fuel. via BBC
