How Asteroid Mining Could Pay for Our First Space Colony

Many of us dream of living on other planets, but are two things we'll need before it can actually happen: money and raw materials. Now some companies say they have a solution to this problem. They'll mine asteroids for valuable metal ores, and for basic resources like water that we'll need once we're far from Earth. » 2/17/15 4:56pm 2/17/15 4:56pm

This Huge Engineering Project May Be Our Best Chance At Colonizing Space

Space colonization has reached an impasse, for reasons far more fundamental than a lack of money for the Space Shuttle program. There is simply no way humans can travel easily offworld without using massive amounts of rocket fuel to escape the gravity well — and that's both expensive and environmentally… » 2/04/15 11:30am 2/04/15 11:30am

Which Religions Are Prepared to Accept Life in Space?

Assuming we don't blow ourselves up before then, colonizing other planets may be the last hope for the survival of humanity. Most of the preparation for this cosmic expansion has centered around solving the more immediate, physical problems of transporting our bodies into deep space, but what about our culture?… » 1/27/15 12:21pm 1/27/15 12:21pm

What Are The Best Reasons Why We Should We Explore Space?

It's difficult to look up on a clear night and not feel the pull to get out there, anywhere, and see a little more of the universe than the little blue marble that we've anchored ourselves on. But, when faced with the need to justify the money, time, and tech to get us there, what are the best reasons to explore space? » 9/29/14 4:20pm 9/29/14 4:20pm

Watch the Synthetic Leaf Creator Explain How We Could Colonize Space

Royal College of Art graduate Julian Melchiorri has developed a "man-made biological leaf," made from chloroplasts and a silk product, that produces oxygen the same way a real plant does. As Melchiorri explains in the video, that could be a boon for space exploration. » 9/25/14 4:30am 9/25/14 4:30am

A Mars One Candidate Explains Why He Wants A One-Way Ticket To Space

Last year, twenty-thousand people were vying for the possibility of a seat aboard the Mars One — the project that aims to stick a human settlement up on Mars. That number has been whittled down to the finalists — and one of them shared his reason with us for trying to get aboard. » 9/09/14 4:38pm 9/09/14 4:38pm

What Would Make You Move To A Space Colony?

With it's rising temperatures, declining energy resources, and rapidly filing landfills, the earth sometimes gets a bad rap. Still, it's a pretty hard-to-beat combination of habitable oxygen-levels and replenishing food sources. So, what would make someone leave all that behind? » 9/08/14 4:20pm 9/08/14 4:20pm

8 Things We Can Do Now to Build a Space Colony This Century

Before humans start living in space on a regular basis, there's a lot of basic science and political agendas that need to advance. We talked to scientists and experts about the fundamental things they think we should do right now, if we want to have a space colony in the next 100 years. » 9/08/14 10:55am 9/08/14 10:55am

Our First Ever Look At The Surface Of The Moon

Fifty years ago exactly today, we got our first up close shot of the surface of the Moon as Ranger 7 beamed back this shot to show us what it could see. » 7/31/14 1:00pm 7/31/14 1:00pm

What One Item Would You Want To Bring Along With You In Space?

If we do someday all get the chance to head outwards deep into space, one thing is for sure: cargo space is going to be limited. So, if your space shuttle only had room for one extra item, what would you bring along with you? » 7/28/14 7:20am 7/28/14 7:20am

Could We Drink The Water On Mars?

It's looking more and more likely that there is indeed flowing, liquid water somewhere on Mars or, at least, forming water. So, if we find it, could we (and should we) also drink it? » 7/16/14 4:20pm 7/16/14 4:20pm

These Are the Mining Robots That Will Colonize the Solar System

How are we going to convince governments and corporations to fund the colonization of space? Probably by promising them riches from mining operations. Here are the space robots that will make that possible. They won't just be mining, either. They'll be building and replicating themselves. » 6/06/14 2:20pm 6/06/14 2:20pm

The One Scientific Field Most Likely to Get Humanity Into Space

If humans are actually going to live on other planets or space stations one day, we're going to need more than rocket fuel and futuristic propulsion systems. We're going to need environmental science. Here are some fundamental reasons why. » 4/09/14 12:27pm 4/09/14 12:27pm

Massive Spaceships Could Be Fueled by Human Exercise

What would be the most efficient way to power a spaceship carrying hundreds of thousands of passengers? According to some newly-published calculations, the best option would be to use the passengers themselves—by harnessing the power of exercise. » 4/01/14 5:00pm 4/01/14 5:00pm

British Think Tank Revives 40-year-old Plan to Build Space Colonies

The esteemed British Interplanetary Society is resurrecting an ambitious idea for creating giant orbiting homes in space. But to make it economically and technically feasible, it will have to rely on a plan devised by Gerard O'Neill back in the 1970s. » 12/03/13 2:40pm 12/03/13 2:40pm

How Self-Replicating Spacecraft Could Take Over the Galaxy

Forget about generation ships, suspended animation, or the sudden appearance of a worm hole. The most likely way for aliens to visit us — whatever their motive — is by sending robotic probes.
