DIY Spaceflight The democratization of space

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.

ENCORE  Everyone talks about the weather but no one does anything about it. Not that they haven’t tried.  History is replete with attempts to control the weather, but we’d settle for an accurate seven-day forecast.

ENCORE  Got aches and pains?  Critters in the Cretaceous would have been sympathetic.  A new study reveals that painful arthritis plagued a duck-billed dinosaur.  Scientists impressively diagnosed the animal’s condition without a house call by examining its 70 million-year old bones.
