If there’s any thread that goes through my career, it’s about how we create mechanisms that are going to support humans in the years to come. The job of the 100 Year Starship, which is part of the Dorothy Jemison Foundation for Excellence, named after my mother, is to make sure capabilities exist in 100 years for interstellar flight, developing a means of pushing mankind to a neighboring star. For the most part, we know what we need to do to get to Mars. But if you’re going to put 5,000 people, for example, aboard a world ship and send them traveling for 50 years before they get someplace, they need enough wherewithal to continue to feed themselves and live. That means we have to learn a whole lot more about food and sustainability.
