They speak of mylar lasting a few months, and something more resistant to space (Kapton, or something like that) lasting for a few years. They also state that it is impractical to sail beyond Mars or Jupiter because of diminished sunlight. There are thoughts on beaming light at a sail to overcome this, but that is another story. /Don Lynn
