Linda Kim Shelmerdine discovered her considerable powers during her hormonal years (the Sun was having similar problems then). But she read the Superheroes' guide books, and her years in 4-H helped, too. Now 59, SpaceGirl is somewhat disillusioned with the way Superheroism is viewed these days, both by the public and by other Superheroes. But she takes her job seriously, and takes occasional vacations at her crater-side retreat on the Moon.
