  1. The 100 Year Starship

    Dr. Mae Jemison was the first black woman in space. Now, she’s leading a wildly ambitious project: to achieve interstellar travel in the next 100 years. She’s with us.

    Think Star Trek and you won’t be far off. A new Pentagon project is putting out seed money for interstellar travel. Humans, rambling around among the stars. It’s called the 100 Year Starship project. It’s as wildly ambitious as just about anything you can imagine.

    The spaceship, its energy source, its passengers’ survival – full-blown or just as DNA… all giant challenges. Not to mention that we’re sort of broke and not even flying space shuttles right now. Leader of the new effort: astronaut Mae Jemison, the first black woman in space. She’s with us.

    This hour, On Point: the 100 Year Starship.

  3. David Deutsch And The Beginning of Infinity

    Quantum computing genius and Oxford don David Deutsch is a thinker of such scale and audaciousness he can take your breath away. His bottom line is simple and breathtaking all at once.

    It’s this: human beings are the most important entities in the universe. Or as Deutsch might have it, in the “multiverse.” For eons, little changed on this planet, he says. Progress was a joke. But once we got the Enlightenment and the scientific revolution, our powers of inquiry and discovery became infinite. Without limit.

  5. Lord Martin Rees: Life and the Cosmos

    It’s famously called the Final Frontier, and thanks to rapidly developing technology we now know more about the outer reaches of our galaxy than ever. But that leaves unknowns.

    Does the universe have any limits? Are there any other earth-like planets out there? And the big one, are we alone?

    Addressing the University of Melbourne recently, Britain’s Astronomer Royal, Lord Martin Rees, reports on the latest research.

  6. Avoiding Armageddon: Diverting Asteroids with Nuclear Explosives

    Every couple of years, the earth is hit by a body with energy near that of the Hiroshima bomb. Deposited high in the atmosphere these events causes little or no damage. On longer timescales, impacts occur with the potential to destroy regions, or whole civilizations. Learn about the impact threat, followed by a systematic development of the requirements to divert such an object.
