Space Greed
Once we've managed to get a handle on building structures to help us live on the harsh, dangerous surfaces of other celestial bodies -- why stop there?

Space Greed
Human needs have always created opportunities for human greed. And energy might be the most crucial need of all. Could we end up paying a subscription fee for sunlight?

Space Greed
Space is home to crucial resources, important discoveries, and big potential profit.

The New Frontier
Stars are a bit like human beings. They can be warm or cold, they come in all kinds of shapes and sizes… and, let's face it, they can be dim or bright. Recent discoveries suggest the number of stars in our galaxy alone may exceed 200 billion.

The New Frontier
For an instrument first developed as recently as the 17th century, the telescope has travelled a long way. The latest version of the once-humble telescope will be going a lot farther – carrying us ever closer to the first light.
2026-01-29 01:18:01 +0000 UTC→2026-01-29 01:48:11 +0000 UTC(30m)
The New Frontier
The question often rises is the cost of space exploration really worth it? Could the money be better spent elsewhere. If so one space program would have to remain. The planetary defence program, to locate identify and deflect a wayward asteroid.

The New Frontier
Our solar system is vast, from our own star the Sun to Earth is nearly 150 million kilometers or 1 Astronomical Unit. Jupiter is 5.2 AU distant and Pluto up to 48AU, the solar system extends far beyond this into interstellar space.

Space Greed
Survival anywhere requires that we adapt to our surroundings but how will humans adapt to survive in space?

Space Greed
Resources are tight in space. Everything that goes up there has mass and therefore a cost.

Suppressed Science
Over the centuries, scientific theories have emerged that rival religious cosmology in terms of ambition and scope. But can science ever truly explain everything?

Survival Science
ATVs have allowed us to penetrate the wilderness like never before. But they've also made the backcountry a bit more dangerous. Laura and Nick rig up some dramatic, high-speed tests to see how accidents happen and what you can do to protect yourself.
