The true, stranger-than-fiction, adventure of eight visionaries who in 1991 spent two years quarantined inside of a self-engineered replica of Earth's ecosystem called Biosphere 2. The experiment was a worldwide phenomenon, chronicling daily existence in the face of life threatening ecological disaster and a growing criticism that it was nothing more than a cult. The bizarre story is both a cautionary tale and a hopeful lesson of how a small group of dreamers can potentially re-imagine a new world.
This is our home, the earth it's, it's the only place we've got. It is one strange rock because it's ours and we are here and we don't know if any other place in the universe, yet, that can support life. We're very lucky to have it as our home. Astronauts including the legendary Peggy Whitson, who spent 665 days in space, speak about how their concepts of home have changed since their experience.
For all of human history, the Sun, our home star, has measured our days and our seasons while fueling all life on Earth. Yet it remains an enigma. NASA's Parker Probe Plus is on a mission to change that, flying through dangerous radiation to become the closest spaceship to orbit our Sun. It's a journey to the center of our solar system, a mission to gather information about the most critical celestial body in the sky, our star.
Every day Astronomers are finding a new planetary system that looks pretty similar to Earth. The possibilities of life somewhere else other than Earth I think are very high. If there is life out there what would it be like? Could we talk to it? Is there anything out there like you and me? To find out, we can't just look into space, we also need to look down here. The story of how a miraculous event transformed life on Earth into a complex interconnected food web; Astronauts and experts question other intelligent life in the universe.
We sure lucked out with Planet Earth. Blue skies, rolling hills, water everywhere. But our home didn't come like this out of the box. Earth was a real fixer-upper, and it took some seriously hard work to build this paradise. Nearly four billion years of renovation. Some tiny, some huge, to make this house a home. Creatures on Earth don't just live and die. They actually change the world around them. The story of how for nearly 4 billion years, microbes, plants and animals have emerged and sculpted the planet's surface and atmosphere in the strangest of ways.
Huge asteroids have smashed into the earth, and turned it into an enveloped fire, uninhabitable to almost all life on the surface. The world will get hit again. It's just a matter of when. So, what should we do as a species? Should we just, like the dinosaurs, look up and die? The reasons the dinosaurs are extinct is they didn't have a space program. We do. We have the capability to perhaps escape the Earth. Astronaut Chris Hadfield believes the only chance for human survival is to escape from Earth and build a space colony, but there are real barriers.
