Why NASA is sending a spacecraft to an asteroid to bring a piece back

Not to be outdone by their ESA colleagues, NASA is sending a spacecraft to an asteroid to bring a piece of it back. Her name is OSIRIS-REx, and she will be visiting Bennu—great name for an outpost in a sci-fi movie—one of the primordial asteroids that have been orbiting the Sun for millions of years.

Playing around with a water bubble in space must never get old

I'm happy when I see astronauts happy. There's something about seeing people in space enjoy all there is about space that's just infectious. Even the little things, like playing around with a giant water bubble blob. I mean, I would do the same thing they're doing. Let it swallow my hands while a GoPro is inside. » 11/05/14 8:58pm 11/05/14 8:58pm

Watch a feather and a bowling ball fall at the exact same speed

To this day, I've never felt dumber than when elementary school me thought that 100 pounds of bowling balls would fall faster than 100 pounds of feathers. This video doesn't show that riddle in action but something even cooler: how things fall at the same rate inside the world's largest vacuum chamber. » 11/03/14 8:36pm 11/03/14 8:36pm

Get goosebumps listening to Carl Sagan talk about space exploration

I'm ashamed to admit that I didn't know about The Sagan Series—an ongoing series of educational videos featuring Carl Sagan's voice created by Reid Gower—until today, when I watched The Frontier Is Everywhere. The combination of his words, his voice, and the imagery gave me the chills. Highly recommended. » 10/23/14 2:11pm 10/23/14 2:11pm

NASA reveals details of mission to capture and bring asteroid near Earth

By the end of the decade, NASA will send a robotic spaceship to grab a 40-foot (12-meter) asteroid and bring it close to Earth, placing it in an orbit around the Moon, and then send astronauts in an Orion spaceship to study it. They just published six papers detailing this historic mission, crucial for humanity's… » 10/01/14 8:13pm 10/01/14 8:13pm

The Webb Space Telescope's sunshield is complete and it looks amazing

NASA has finished and stacked the Sunshield for the Webb Space Telescope and it's now getting ready to test it. Look at this huge thing. That's enough tinfoil to cover a roasted chicken— if the chicken was the size of Tyrannosaurus Rex. According to NASA, it provides the equivalent of a 1,000,000 Sun Protection Factor. » 7/25/14 6:11pm 7/25/14 6:11pm

What's hiding behind these giant holes on the Moon?

You've probably seen the mysterious giant hole that was discovered in Siberia, which appears to lead into a large cave. We don't know its origin yet, but it isn't the only hole like that on Earth. Or the Moon: NASA found these formations there too, which are perfect for future human outposts. Or current alien/Nazi UFO… » 7/17/14 7:37pm 7/17/14 7:37pm
