    Many years from now, space travelers will zip around the solar system in
    extraordinary spaceships. Meteoroids? No problem. Punctures in the hull
    will heal themselves. Radiation? Astronauts will be shielded from the most
    powerful cosmic rays. Low on fuel? Impossible. The craft will be propeled
    by inexhaustible sunlight pressing against a lightweight solar
    sail--kilometers wide yet only a few molecules thick.

    How do you make such a super-spaceship? The first step is to find the
    right building materials.
