Low Gravity Seriously Messes With An Ant's Ability To Explore Space

Experiments aboard the International Space Station with common pavement ants have shown just how badly microgravity impairs the insects' ability to search unexplored areas. Remarkably, however, tumbling ants demonstrated an uncanny ability to regain contact with the surface. » 3/31/15 7:00am Today 7:00am

These Astronauts Are Having Way Too Much Fun With This GoPro

Have you ever wondered what the International Space Station might look like from inside a floating ball of water? Your wish has been answered. » 11/05/14 7:20am 11/05/14 7:20am

Oh Man, All The Space Sex Geckos Are Dead

Sad news from Russia's Foton-M4 satellite. The spacecraft on which a group of geckos spent a few weeks trying to get it on in microgravity returned to Earth, as planned, earlier today. The only problem? The lizards were frozen solid. » 9/01/14 5:42pm 9/01/14 5:42pm

Candid Videos Of Astronauts Being Dorks In Space Are Just Adorable

What do the ISS astronauts do in their free time? Sometimes, they like to act out action movie scenes—and the part where a character falls to his death is much more fun in microgravity. That's when they aren't playing with their floating food or doing weightless backflips. » 6/27/14 12:40pm 6/27/14 12:40pm

Hearts Weaken, Shrink And Become Spherical In Space

A new study of a dozen NASA astronauts has found that exposure to microgravity causes hearts to become more spherical in shape — a change that could lead to serious cardiac problems while in space and back on Earth. » 3/31/14 9:40am 3/31/14 9:40am

What the hell are 800 ants doing on the International Space Station?

No, it's not a scene from a classic Simpson's episode, but rather an experiment that could lead to highly adaptable robots. » 1/20/14 2:33pm 1/20/14 2:33pm

Going into space accelerates the aging process

As if astronauts didn't already have enough health-related concerns to be worried about, a new study shows that microgravity environments speed up biological aging and the onset of cardiovascular disease by affecting blood vessel cells. » 11/01/13 1:20pm 11/01/13 1:20pm

How to drink coffee in space without burning your face off

Zero gravity is all fine and well — but not being able to grab a cup of joe in the morning would be a huge dealbreaker for many prospective astronauts. Thankfully, NASA has a solution to the problem. » 7/15/13 7:20am 7/15/13 7:20am

Behold a piece of art that could only be created in zero gravity

What do you do if you're a physicist and want to get experiments done in microgravity, but can't drum up the cash to go to space? You use magnets to both get results and make a picture that looks like it came out of 2001: A Space Odyssey. » 6/19/13 3:20pm 6/19/13 3:20pm

This is what happens when you play with fire in space

The simple flame is an extraordinarily complex phenomenon, one that involves thousands of chemical reactions. But fire also plays off the effects of gravity. So what happens when you take that gravity away? As a recent experiment aboard the ISS has shown, you get a very strange flame, indeed. » 6/19/13 7:40am 6/19/13 7:40am

Proof that making burritos is more fun in space

Burritos are already the food that comes in a delicious wrapper, but there's nothing quite as delightful as a zero-gravity burrito spinning around as you assemble it. In this scene from 2010's Hubble 3D, an astronaut prepares for his spacewalk with a light, floating snack. » 7/07/12 10:30am 7/07/12 10:30am

Long space journeys could wreck your eyeballs... and brain

Fresh off the news that microgravity screws us up on a cellular level comes word that it also damages our eyes and brain. Researchers from the University of Texas, Wyle Integrated Science and Engineering, and NASA's Department of Space Medicine performed MRIs on 27 astronauts who had spent an average of 108 days in… » 3/16/12 7:40am 3/16/12 7:40am

Microgravity screws us up at a cellular level

One of the great fears of the early space race was what effect microgravity would have on human explorers — and while we know it won't instantly die when leaving the atmosphere, there's still a lot we don't know about the long term effects of low gravity. If we ever want to set up a long-term space settlement, it'd be… » 2/02/12 3:00pm 2/02/12 3:00pm

Fruit flies become slightly superpowered in zero gravity

Fruit flies were the very first animals we sent into space, way back in 1947 — yet we're still not done analyzing what happens to them in microgravity. We've known for a while that when in "zero-gravity," flies walk more quickly than they do planetside. The only problem is that we don't know if this is due to the… » 1/04/12 10:53am 1/04/12 10:53am

A Mouse Defies Gravity Using Nothing But Magnets

In a study commissioned by NASA, a research team at the University of Missouri has made a mouse levitate, using nothing but magnetic fields. As a result, the poor mouse floats in mid-air, wondering where the ground went. » 9/09/09 1:20pm 9/09/09 1:20pm

Baby-Making is Tougher in Space

Many space age dreams involve humans spreading out into the far reaches of the galaxy, but our extraterrestrial breeding program might need a little help. Scientists in Japan have found microgravity may function as a form of birth control. » 8/25/09 4:34pm 8/25/09 4:34pm
