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)

A visit to Ceres and the Asteroid Belt.
Ceres, a dwarf planet amid the Asteroid Belt, hold the potential to be the hub of a vast mining and manufacturing network in the Belt, as well as potentially growing the food to support future colonists. Today we'll look at colonizing Ceres and asteroid mining, faming in space, and a potential distant future of a developed asteroid belt.

Colonizing Ceres (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 look at Neptune, a potential gateway to the stars...
The Icy Giants, Neptune and Uranus, are often overlooked for as candidates for colonizing our solar system. Even when noted, the focus tends to be on their larger moons like Triton. Today we will challenge that notion by looking at way we might place a colony on the planet itself, and how Orbital Rings and Chandelier Cities might let us colonize any gas giant. We will also look at how helium-3, a core ingredient of aneutronic fusion abundant on Neptune, might serve as the fuel of future starships, and the physics behind some other starship drives future science might give us access to, such as laser propulsion.

Colonizing Neptune (Narration Only)

Interstellar travel is very time consuming, moving from star to star, but perhaps we could use stars themselves as spaceships, and move whole solar systems or even galaxies.
Today we'll look at how to use Shkadov Thrusters, novas, supernovae, black holes and quasars to move through space, literal starships.

Fleet Of Stars (Narration Only)

In order to get into space, we require either huge amounts of rocket fuel or dangerously powerful energy sources, making personal spacecraft a technology limited to science fiction. But by harnessing beamed power sources to run engines, we may be able to create a spaceplane cheap enough and safe enough that  anyone could have one in the future.

Beam Powered Spaceships (Narration Only)

Natural disasters can topple civilizations, even in modern times, but with more and more technology civilizations become more robust and capable of predicting future calamities and preventing such ruin. So what other threats face spacefaring civilizations, both at the interplanetary and interstellar scale?

Threats to Interplanetary & Interstellar Civilizations (Narration Only)

Venus is a desolate scorching world on which no life can exist. Yet if it can be cooled down, there is no other planet we know of more suitable for terraforming and colonization. We will examine methods of cooling Venus down and preparing it to be settled in the future.
