Augmented Reality for Drone Air Traffic Management (video)
NASA is using augmented reality software to bring drone air traffic information to life using commercially available headsets. Flight paths, volumes, current positions, and status are just some of the information that can be seen using the interactive software. Fed by real-time data from NASA’s Unmanned Aircraft Systems Traffic Management project, the software will give…

The dust bunnies that built our planet – Lorin Swint Matthews (video)
Consider the spot where you’re sitting. Travel backwards in time and it might’ve been submerged at the bottom of a shallow sea, buried under miles of rock or floating through a molten landscape. But go back about 4.6 billion years, and you’d be in the middle of an enormous cloud of dust and gas orbiting…

Could we survive prolonged space travel? – Lisa Nip (video)
Prolonged space travel plays a severe toll on the human body: microgravity impairs muscle and bone growth, and high doses of radiation cause irreversible mutations. As we seriously consider the human species becoming space-faring, a big question stands: even if we do break free from Earth’s orbit, can we adapt to the extreme environments of…

Eye vs. camera – Michael Mauser (video)
Your eyes don’t always capture the world exactly as a video camera would. But the eyes are remarkably efficient organs, the result of hundreds of millions of years of coevolution with our brains. Michael Mauser outlines the similarities and differences between your eye and a video camera.

Is Mars’ Soil Too Dry to Sustain Life?(article)
Article by Space Messengers Speaker Frank Tavares: Life as we know it needs water to thrive. Even so, we see life persist in the driest environments on Earth. But how dry is too dry? At what point is an environment too extreme for even microorganisms, the smallest and often most resilient of lifeforms, to survive?…

What’s the smallest thing in the universe? – Jonathan Butterworth (video)
If you were to take a coffee cup, and break it in half, then in half again, and keep carrying on, where would you end up? Could you keep on going forever? Or would you eventually find a set of indivisible building blocks out of which everything is made? Jonathan Butterworth explains the Standard Model…

Earth Climate Models Bring Exoplanet To Life (video)
In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening chorus of data crunching. Day and night, they spit out five quadrillion calculations per second. Known collectively as the Discover supercomputer,…

What are gravitational waves? – Amber L. Stuver (video)
Ted Ed video: In September 2015, scientists witnessed something never seen before: two black holes colliding. Both about 30 times as big as our Sun, they had been orbiting each other for millions of years. A fraction of a second before the crash, they sent a vibration across the universe at the speed of light…
