Biosphere 2 Science for the Future of Our Planet

20 個評分

Are you ready to take an incredible journey around Planet Earth and beyond? In this course, you will delve into a world of innovative science and learn from a team of Biosphere 2 and University of Arizona researchers. From plants and soils, to oceans and rainforests, the Moon, Mars, and more, this course is an exciting opportunity for anyone interested in science and Earth stewardship. Learn how a unique research station in the Arizona desert is used to investigate big ideas, such as how Earth systems interact, the effects of climate change, and what our future holds. Go back in time thousands of years with information locked in ancient trees, and travel into an imagined future where humans become Martians. Collect and analyze your own scientific data, discuss big questions with participants from around the world, and gain novel insights and understanding about our wonderfully unique planet.

Life and Resources in Space - Should We Go There?

When will humans live beyond Earth’s gravity? Module 9 is a fascinating and inspiring journey into space. Ignite your imagination as you learn about space tourism, asteroid-mining, moon elevators, robotic space explorers, and Mars colonization. While focusing on space, this module is sure to reaffirm your appreciation of Planet Earth. With Dr. Chris Impey, Associate Dean UA College of Science, UA Astronomy.

Biosphere 2

We're going to have

to go beyond what's happened in biosphere.

There is going to have to be more innovation.

I'm Chris Impey, Associate Dean for the College of Science,

Distinguished Professor of Astronomy at the University of Arizona.

My module is the last one where we sort of expand beyond the framework of

the biosphere and the Earth itself to imagine

what resources might be needed to live beyond the Earth.

The original model of the biosphere was a completely self-contained habitat, which means,

you could imagine a biosphere on the surface of the moon, or Mars,

or another location where people are self-sufficient and self-contained.

This is a real challenge to be in

such a wonderful new environment offer and yet to be so contained.

The lessons of the biosphere on complexity on

interconnectedness of all these ecosystems should

advise and inform an experiment of how to live

off Earth in a sort of simplified version of an ecosystem.

So, humans are driven to explore.

It wasn't done for food or resources.

It was done for some curiosity of nomads just wanting to see what was beyond.

As we did that with our own planet,

and as soon as we got the technology,

we started doing it in space as well.

And then, the question becomes,

how can we do it safely and sustainably?

So, astronomy has taught us that the Earth is

a very special place and also taught us therefore,

that if we leave the Earth,

which we seem to have an inclination to do,

we're going to be in situations where we have

to be able to survive in hostile environments.

These places we might go off Earth are far less hospitable than the Earth and Mars.

The Moon essentially, no atmosphere, arid,

cold, extreme amounts of radiation.

So, you do actually have to have

a completely self-contained ecosystem living situation on each place.

And we're sort of approaching a time when we could visit the moon and Mars and

stay there for an extended period or maybe eventually colonize the surface.

So, biosphere becomes relevant once again.
