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

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

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

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

Episode 144: Power Satellites - How transmitting power down from space may be our future.
Visit our sponsor: https://skl.sh/isaac2
Beaming energy down from satellites in orbit to replace the production of electricity on Earth may solve many of our problems, and avoid a potential economic or ecological crisis such as energy bottlenecks or global warming. Today we will explore how wireless microwave transmission of energy down to rectennas may not only be possible, but could be massively profitable in the near future and spur our exploration and colonization of space.

Power Satellites

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

A look at environments and ecology on truly massive space stations.
Check out Cheddar's video on Extinction: https://chdr.tv/youtu0277c
As we expand in space and build ever large space stations, true space habitats, we will need to incorporate ecosystems into them. However, such space habitats will have their own weather and cycles unlike those of Earth, and we will need to adapt to those unique conditions, which will vary by size and type. Today we will look at everything from smaller rotating habitats like Kaplana One and O'Neill Cylinders to vast structures such as Ringworlds, Supramundane Planets, Mega-Earths, and see the unique challenges each of them will offer us in the future.

The Environments Of Space Habitats

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

So often expanding into space can seem like a Catch-22, where every proposed idea for development can only be practical if space is already developed. Today we'll take a look at some potential options for pushing forward our orbital infrastructure such as asteroid mining or power satellites, and take a look at what other technologies and industries might start the avalanche to our future in space and on other planets.

Kickstarting Space Industry

The option of using floating platforms, balloons, or cargo air planes to launch rockets into space and save fuel is often discussed but rarely employed. Today we'll look at stratostations, rockoons, and other suggested methods for getting into space using these methods.

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.
