Walt Disneys Wonderful World of Color - Earth Star Voyager Ep 1 - 2, 1988 in English Eng

The Earth Star Voyager is a spaceship sent to another solar system to prepare it for colonization. Earth itself is horribly polluted, so the mission is vitally important. But as the departing starship gets under way, signs begin to emerge that their mission may unwittingly be part of a larger conspiracy.
