Astronauts typically need a couple of days to get used to microgravity. But as Tim Peake demonstrates in this new video, astronauts eventually develop an extreme tolerance to all that spinning and floating.
Sometimes you just need to cut loose—from the Earth’s gravity. Want to feel what it’s like to be free from gravity, but can’t get yourself to the ISS? You’ve got some options.
We all dream of journeying (or living) among the stars. But space is a spectacularly awful place for humans, and we’re not suited for life there at all. And yet, it doesn’t have to be that way. Here are all the ways we’ll need to re-engineer the human body, in order to make space our home.
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.
How do you test a new method for CPR in space without actually going into space? You take flight in a microgravity plane, obviously. For the last 20 years, NASA's Reduced Gravity Office has opened up its zero-g planes to college students from around the country, who get the once in a lifetime opportunity to test…
Last week we showed you how NASA simulates space here on Earth, with everything from advanced virtual reality to monstrous thermal vacuum chambers. But all of that still can’t prepare you for how an object, or an experiment, will behave in zero gravity. Sometimes you just have to fly.
Have you ever wondered what the International Space Station might look like from inside a floating ball of water? Your wish has been answered.
We didn't think the zero-G fire experiments aboard the International Space Station could get any more stunning. We were wrong.
In honor of World Snake Day, which is today, here's what happens when you put a bunch of snakes on a plane...for science.
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.
A brief exchange in the back of last week's issue of New Scientist asks: "I understand that the lines and sagging skin we acquire as we age are due to the sun and gravity. If I lived in a space station in zero or microgravity away from the sun, would I stay looking young?" A perfectly innocuous, if even somewhat…
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.
No, it's not a scene from a classic Simpson's episode, but rather an experiment that could lead to highly adaptable robots.
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.
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.
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.
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.
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.
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…
