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.

The Voyager 1 spacecraft is now 11 billion miles from Earth, speeding along at 38,000 miles per hour towards the edge of the heliosphere, the bubble that surrounds the solar system. Voyager chief scientist Ed Stone discusses the craft’s discoveries about the environment at the edge of the solar bubble.
Sean M. Carroll of CalTech discusses how the direction of the arrow of time was defined by the Big Bang. He also speculates about what might have come before the Big Bang. The lecture is entitled The Origin of the Universe & the Arrow of Time.
