Stephen Petranek explains why colonizing Mars may be sooner than you’d think in this TED Talk.

It sounds like science fiction, but journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. In this provocative talk, Petranek makes the case that humans will become a spacefaring species and describes in fascinating detail how we’ll make Mars our next home. “Humans will survive no matter what happens on Earth,” Petranek says. “We will never be the last of our kind.” 

In the middle of the New Mexico desert lies Spaceport America, a glittering, alien structure advertised as the very first purpose-built commercial spaceport.

It’s home to Virgin Galactic, a space startup that promises to send tourists into orbit as early as next year.

But even if that milestone happens, it will follow years of delays, setbacks, and even tragedy. Local residents in the nearby town of Truth or Consequences were told to expect big things when New Mexico joined the private space economy, but many now wonder if the dream of a space industry will ever materialize.

Lex Fridman interviews Elon Musk in this fascinating podcast.

Elon Musk is the CEO of Tesla, SpaceX, Neuralink, and a co-founder of several other companies. This is the second time Elon has been on the podcast. You can watch the first time here: https://www.youtube.com/watch?v=dEv99vxKjVI This conversation focuses on the incredible engineering and innovation done at Neuralink. This work promises to help treat neurobiological diseases, to help us further understand the connection between the individual neuron to the high-level function of the human brain, and finally to one day expand the capacity of the brain through two-way communication with computational devices, the Internet, and artificial intelligence systems.

Microgravity can be used to unlock old materials and make new ones in ways that can’t be replicated on Earth. Private companies know this, and are leading the charge toward the next gold rush. But can they turn low Earth orbit into a home for the next industrial revolution?
