In this episode we examine the concept of a Space Elevator, a popular piece of developing technology designed to lift people and cargo into space at a fraction of normal launch costs. We will look at technology as well as many of the misconceptions about Space Elevators which have emerged.

Upward Bound: Space Elevators (Narration Only)

In this episode we examine the Skyhooks and Rotovators, technology designed to lift grab spaceplanes or rockets at far slower speeds than normal and lift them into space at a fraction of normal launch costs.

Upward Bound: Skyhooks (Narration Only)

In this episode we'll be looking at improvements to rocket systems, with the main focus on re-usability. We will also look a bit deeper at rocketry principles, at some other improvements and alternative uses for rockets, such as oceanic launches, and discuss Metallic Hydrogen, a potential game changing fuel.

Reusable Rockets (Narration Only)

While potentially dangerous, nuclear powered spacecraft offer far faster and more efficient spacecraft than traditional chemical rockets. Today we will examine the various means of using atomic power sources to propel spacecraft, bot to get off Earth and to travel to other stars.

The Nuclear Option (Narration Only)

The Launch Loop is a type of space vehicle launch assist mechanism that allows us to transfer vast amounts of energy and  momentum from ground based generators to a launch vehicle high in the upper atmosphere.

Launch Loops (Narration Only)

Today we look at using Space Towers, Buoyant Structures, Airships, and Space Fountains as means of launching spaceships, as well as their other applications to create enormous structures that normal materials could never permit.

Space Towers (Narration Only)

The Orbital Ring is a type of launch-assist system that goes beyond moving small ships and crews into space and allows cheap movement of bulk cargo up to space, into orbit, and beyond.

Orbital Rings (Narration Only)

To explore space and expand beyond Earth we will need a robust orbital infrastructure to serve as our beachhead. Today we will explore the necessary components for that, how we will go about creating them, and threats to them like Kessler Syndrome, a potential cascade destruction of all our space-based assets.

Orbital Infrastructure (Narration Only)

Could we grow our foods in the heavens rather than on the earth?
In order to do serious exploration and colonization of space, we will need a source of food beyond Earth. But can we go beyond simply small hydroponic gardens to entire vast space farms in orbit of our planet, and could those farming on satellites and space stations eventually replace earth-based agriculture as our main food source at home?

Space Farming (Narration Only)

A Moon Base may be built within a generation, but long term colonization will take many more. As more people travel and immigrate their, establishing more lunar colonies, tension between them and Earth could lead to conflicts and possibly even warfare.

Battle For The Moon (Narration Only)

Earth has often been compared to a spaceship, one that's successfully orbited our star and the galaxy many times over billions of years. So what about moving our planet or even converting it or another world into a spaceship? Can we use entire planets to cross the intergalactic void to settle planets in distant galaxies or superclusters? And what sort of engine and drive could move a whole planet?
