Two Paths To The Moon

摘要

U.S. President George W. Bush has challenged NASA to once again "explore space and extend a human presence across our solar system." Those who believe in the future and in freedom embrace this vision of permanence in space for Americans and for humankind. His new initiative places the president squarely in support of the movement of civilization into the solar system and "into the cosmos." If sustained by Congress and future presidents, American leadership of this expansion of the ecological reach of our species will be accompanied by the transfer of human freedom, first to the moon, then to Mars, and, ultimately, beyond.
