THIS IS COOL:

In an effort to promote space exploration, a private group plans today to launch the first spacecraft to sail in Earth orbit on the solar wind.

If successful, the mission will provide scientific proof for a concept that has captivated science fiction for decades – that ships can travel great distances across the heavens under the power of giant solar sails nudged by the faint energy of light itself.

The “today” in this story is actually tomorrow, Tuesday. Let’s hope it works!
