ENCORE  For a half-century, space has been the playground of large, government agencies.  While everyone could dream of becoming an astronaut, few could actually do so. Things have changed.  We hear how a geeky son of immigrant parents incentivized the ground-breaking launch of SpaceShipOne, and spawned the commercial rocket industry.  And while you’re waiting for a ticket to ride, why not build your own satellite to keep tabs on the kids or just check out the back forty?  A CubeSat could be your next basement project. And the hitherto untold story of how black women mathematicians a half-century ago helped get a man into orbit, and astronauts to the moon.
