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 unsustainable.… » 6/15/15 2:06pm 6/15/15 2:06pm

This Watery Graveyard Is the Resting Place for 161 Sunken Spaceships

In a remote stretch of the Pacific Ocean southeast of New Zealand, the broken remains of space stations and robotic freighters litter the ocean floor, four kilometers below the waves. The world’s space agencies call this region the South Pacific Ocean Uninhabited Area. But it’s also called the Spacecraft Cemetery. » 5/14/15 4:10pm 5/14/15 4:10pm

How We'll Build The First 'Spacecoach' To The Stars

If we’re going to venture out into the Solar System and beyond, we’re going to need versatile and reliable spaceships. One possible solution comes in the form of “spacecoaches” — reusable vessels that are self-sufficient and capable of carrying explorers to virtually any destination. Here’s how they’ll work. » 5/04/15 10:40am 5/04/15 10:40am

A Failed Lab Experiment Accidentally Invented a Replacement For Cement

As the world’s cities expand at faster and faster speeds, so does its use of cement. One oft-quoted statistic shows that China alone used as much cement in the last three years as the US used in the last 100. Just one problem: Cement is responsible for pushing a hell of a lot of carbon dioxide into the world. » 4/16/15 4:29pm 4/16/15 4:29pm

Study Suggests Magnetic Fields Can Control Heat And Sound

More than a hundred years ago, physicists discovered that heat is simply the energy stored in the vibrations of atoms. This meant that heat and sound are related. Now, for the first time ever, scientists have experimentally shown that these atomic vibrations have magnetic properties, too. » 3/25/15 11:40am 3/25/15 11:40am
