"Humans will survive no matter what happens on Earth,"...

Roman Mars is obsessed with flags -- and after you watch this talk, you might be, too. These ubiquitous symbols of civic pride are often designed, well, pretty terribly. But they don't have to be. In this surprising and hilarious talk about vexillology -- the study of flags -- Mars reveals the five basic principles of flag design and shows why h...

So the Mars Rovers didn't scoop up any alien lifeforms. Scientist Penelope Boston thinks there's a good chance -- a 25 to 50 percent chance, in fact -- that life might exist on Mars, deep inside the planet's caves. She details how we should look and why.

Planetary scientist Joel Levine shows some intriguing -- and puzzling -- new discoveries about Mars: craters full of ice, traces of ancient oceans, and compelling hints at the presence, sometime in the past, of life. He makes the case for going back to Mars to find out more.

Learn all the hubbub going on with the big Red Planet in these insightful and utterly fascinating talks.

A manned mission to Mars has long captivated our collective imagination. Perhaps the most significant obstacle to achieving this mission is fueling a craft to and from Mars. Erika Debenedictis offers some compelling theories on how we can make it happen.

At Serious Play 2008, Charles Elachi shares stories from NASA's legendary Jet Propulsion Lab -- including tales and video from the Mars Rover project.

Stellar astronomer and TED Senior Fellow Lucianne Walkowicz works on NASA's Kepler mission, searching for places in the universe that could support life. So it's worth a listen when she asks us to think carefully about Mars. In this short talk, she suggests that we stop dreaming of Mars as a place that we'll eventually move to when we've messed ...

While we like to imagine little green men, it's far more likely that life on other planets will be microbial. Planetary scientist Nathalie Cabrol takes us inside the search for microbes on Mars, a hunt which counterintuitively leads us to the remote lakes of the Andes mountains. This extreme environment — with its thin atmosphere and scorched la...

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.

NASA engineer Bobak Ferdowsi helped the Curiosity rover land on Mars -- and he's curated these talks that deepen our understanding of the world around us.

What would it take to live on Mars? In an imaginative talk, architect Bjarke Ingels shares his prototype Martian "city" in Dubai, where they're building technologies that humanity would need to thrive on the Red Planet.

When form and function don’t exactly match up, these speakers offer masterful advice on how to keep good design in mind. (Sorry, Pocatello.)

Every minute, 400 pounds of hydrogen and almost 7 pounds of helium escape from Earth's atmosphere into outer space. Astrophysicist Anjali Tripathi studies the phenomenon of atmospheric escape, and in this fascinating and accessible talk, she considers how this process might one day (a few billion years from now) turn our blue planet red.

Elon Musk discusses his new project digging tunnels under LA, the latest from Tesla and SpaceX and his motivation for building a future on Mars in conversation with TED's Head Curator, Chris Anderson.

With his show 99% Invisible, Roman Mars discovered new ways to jolt public radio out of its old paradigms, while at the same time spinning riveting tales of design.

Nagin Cox explores Mars as part of the team that operates NASA's rovers.

While it may not be simple or easy, these fascinating talks make aerospace engineering a little more accessible to the average person.

What would it take to settle Mars? In a talk about the future of space exploration, Lynn Rothschild reviews the immense challenges to living elsewhere in the universe and proposes some bold, creative solutions to making a home off planet Earth -- like "growing" houses out of fungi or using bacteria to help generate electricity.

"Venus is too hot, Mars is too cold, and Earth is just right," says planetary scientist Dave Brain. But why? In this pleasantly humorous talk, Brain explores the fascinating science behind what it takes for a planet to host life -- and why humanity may just be in the right place at the right time when it comes to the timeline of life-sustaining ...

Canadian filmmaker Martin Villeneuve talks about "Mars et Avril," the sci-fi spectacular he made with virtually no money over a seven-year stretch. In this charming talk, he explains the various ways he overcame financial and logistical constraints to produce his unique and inventive vision of the future.

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...

Cynthia Breazeal wonders: Why can we use robots on Mars, but not in our living rooms? The key, she says, is in training robots to interact with people. Now she dreams up and builds robots that teach, learn -- and play. Watch for amazing demo footage of a new interactive game for kids.

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 ...
