This month marks the fiftieth anniversary of Apollo 11, the NASA mission that first put men on the moon. In the decades since Apollo 11, the American space program has atrophied. No manned American space mission has left low Earth orbit since 1972. But recent developments in the space programs of other nations, along with new interest in space from private industry, have instigated a new interest in an American space program. The Trump Administration has announced plans to build an American military presence in space, and also its intentions to send another manned mission to the moon. Rivka Galchen joins Dorothy Wickenden to discuss what’s next in outer space.
