Could we grow our foods in the heavens rather than on the earth? Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ 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...
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...
To see deeper into space, we will need much bigger telescopes. Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ As astronomy seeks to find and study distant planets and peer further and more accurately into space and time, the limitations of ground...
A look at O'Neill Cylinders, immense space habitats. Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Far larger than any conventional Space Station, O'Neill Cylinders could potentially serve as as entire city-states or nature preserves. Today we will...
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...
We return to the Upward Bound Series to look at spaceports, giant structures dwarfing the modern International Space Station, with a focus on the Gateway Spaceport design. If you want to help out the Gateway Foundation or get notifications:...
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. The channel has reached 100,000 subscribers just before this episode's release,...
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. View Lofstrom's 2009 updated paper:...
