That wormhole lets us travel to other stars. It came along right as we needed it. They've put potentially habitable worlds right within our reach. Twelve, in fact, from our initial probes. - You sent probes into that? - Mm-hm. We sent people into it. Ten years ago. The Lazarus missions. Twelve possible worlds... twelve Ranger launches carrying... the bravest humans ever to live... led by the remarkable Dr. Mann. Each person's landing pod had enough life support for two years. But they could use hibernation to stretch that... making observations on organics over a decade or more. Their mission was to assess their world, and if it showed potential... then they could send out a signal, bed down for the long nap, wait to be rescued. And what if the world didn't show promise? Hence the bravery.
