Today the Japan Aerospace Exploration Agency (JAXA) is set to launch the first spacecraft that will speed across the solar system using a hybrid solar sail—one propelled partly by solar pressure, partly by traditional solar power.

First proposed in the 1920s, solar sails are large reflective membranes that allow a spacecraft to be pushed by radiation pressure from sunlight, negating the need for heavy onboard fuel.

It's good to see that this has come to fruition at long last.  Let's hope it works.
