  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. 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.
