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.” 

Dava Newman is the Apollo Program professor of AeroAstro at MIT and the former Deputy Administrator of NASA and has been a principal investigator on four spaceflight missions. Her research interests are in aerospace biomedical engineering, investigating human performance in varying gravity environments.

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?

Bloomberg takes a look at the future of non-terrestrial real estate.

Over the past few decades, the International Space Station has allowed astronauts to live, work and conduct research in microgravity. But with the station’s planned retirement by 2030, private companies are being asked to create the next generation of space habitat.

Bloomberg describes how the first trillionaires will come to be.

There are millions of asteroids in our solar system. Because some are full of materials that are rare on Earth, they have been valued at stupendous amounts. But the most valuable resource in space may be something that’s abundant back on the ground.
