In the next two decades, human beings will return to the moon, set foot on Mars, and launch telescopes capable of detecting extraterrestrial life.

Brian Greene is joined by Zurbuchen, Japan's Masaki Fujimoto, Europe's Kirsten MacDonnell and Australia's Aude Vignelles, as they reveal their plans for what promises to be a New Golden Age of Space Exploration.
