“Space exploration must be undertaken not only out of simple human curiosity but also to further the survival of the species. The twentieth century has seen the unprecedented development and proliferation of magnificent technologies. Many of them, through design, ignorance, or misuse, are capable of destroying life as well as enhancing it. Space exploration alone holds the promise of eventual escape from a dying planet, provided we wisely manage our resources in the meantime and actually survive that long.” HumansWellsLongSimpleSpaceTechnologyCenturyDyingDesignIgnorancePlanetsDevelopmentPromiseSurvivalCapableResourcesSpeciesCuriosityManageExplorationDestroyingMagnificentTwentieth CenturySpace ExplorationUnprecedentedMisuseProliferation Author:Edgar Mitchell
