In this streaming audio and video panel discussion from MIT, three space experts make their predictions about what the next 100 years will bring when it comes to exploring space.
They talk about potential ways to make space travel cheaper and more accessible along with power point presentations of images to help us visualize some of these developments. The talk is quite informal, and the lecturers have fun with it. There's a lot of interesting topics addressed such as the state of the U.S. space program, the possibilities of asteroids hitting the earth, and much more.
