Nagin Cox What time is it on Mars?
Nagin Cox is a first-generation Martian. As a spacecraft engineer at NASA's Jet Propulsion Laboratory, Cox works on the team that manages the United States' rovers on Mars. But working a 9-to-5 on another planet — whose day is 40 minutes longer than Earth's — has particular, often comical challenges.
Xavier De Kestelier Adventures of an interplanetary architect
How will we live elsewhere in the galaxy? On Earth, natural resources for creating structures are abundant, but sending these materials up with us to the Moon or Mars is clunky and cost-prohibitive. Enter architect Xavier De Kestelier, who has a radical plan to use robots and space dust to 3D print our interplanetary homes. Learn more about the emerging field of space architecture with this fascinating talk about the (potentially) not-too-distant future.
Lisa Nip How humans could evolve to survive in space
If we hope to one day leave Earth and explore the universe, our bodies are going to have to get a lot better at surviving the harsh conditions of space. Using synthetic biology, Lisa Nip hopes to harness special powers from microbes on Earth — such as the ability to withstand radiation — to make humans more fit for exploring space. "We're approaching a time during which we'll have the capacity to decide our own genetic destiny," Nip says. "Augmenting the human body with new abilities is no longer a question of how, but of when."
Stephen Petranek Your kids might live on Mars. Here's how they'll survive
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."
Lisa Dyson A forgotten Space Age technology could change how we grow food
We're heading for a world population of 10 billion people — but what will we all eat? Lisa Dyson rediscovered an idea developed by NASA in the 1960s for deep-space travel, and it could be a key to reinventing how we grow food.
Jane Poynter Life in Biosphere 2
Jane Poynter tells her story of living two years and 20 minutes in Biosphere 2 — an experience that provoked her to explore how we might sustain life in the harshest of environments.
Armando Azua-Bustos The most Martian place on Earth
How can you study Mars without a spaceship? Head to the most Martian place on Earth — the Atacama Desert in Chile. Astrobiologist Armando Azua-Bustos grew up in this vast, arid landscape and now studies the rare life forms that have adapted to survive there, some in areas with no reported rainfall for the past 400 years. Explore the possibility of finding life elsewhere in the universe without leaving the planet with this quick, funny talk.
