If you're heading to the International Space Station, try to bunk in the Japanese section. It's as quiet as a Zen temple.

Canadian astronaut Chris Hadfield recently went aboard the ISS and has been recording what it sounds like. It's not quite the elegant "2001: A Space Odyssey" experience you might expect. It's more like a noisy tin can.

After recording last week the ambient sounds of the U.S. lab, with its noisy air pumps and fans, Hadfield managed to get samples of what the ISS toilet sounds like, as well as the relative serenity of the Japanese Experiment Module (aka Kibo). … Read more

I have a bone to pick with predictions. I was supposed to have my own personal jetpack by the year 2000. I'm still waiting. That's why I'm just a little skeptical about this BBC Future infographic that looks ahead a century and a half.

As we reported earlier this week, the infographic is packed with predictions ranging from "most likely" to "least likely" from 2013 until 150 years into the future.

For this year, the BBC is giving us pretty good chances that the Great Firewall of China will fall and that doctors … Read more

My brother has told me that if a manned Mars mission were seeking volunteers, he'd be the first in line, even if it meant never coming back. I wouldn't want him to go, but my desire to keep him Earth-bound is even more intense after checking out a new study on the impact of radiation on potential manned Mars missions.

A study published in PLOS One looks at the effects of galactic cosmic radiation on mice. Researchers exposed the mice to particle irradiation like that found in space. The result was cognitive impairment in line with the symptoms of Alzheimer's disease.… Read more

No matter how much you keep up with technology, it's challenging to predict its impact past a few years down the road. There are so many possibilities on the horizon -- especially considering the non-stop advancements in connectivity, nanotechnology, and other expanding fields of next-gen science -- that future generations may think of the early 2000s in the same way we think of the early 1900s: as a time when society stood on the cusp of incredible change.

A new BBC Future infographic takes a shot at what could happen in the realm of science, technology, and society as a whole from now to 2150. The predictions, which come from a cavalcade of sources (IBM, MIT, NASA, news outlets, and many others), indicate that the world we know today could be largely different in just a decade. … Read more

Looking out my window, it's a beautiful sunny day. Perhaps it's even a bit sunnier than usual here in New Mexico. Turns out, there may be a reason for that. The Earth is as close to the sun today as it will be for the whole year of 2013.

How close is close? The Earth is a mere 91,402,560 miles away from the sun today. Usually, we're right around 93 million miles. The phenomenon of getting all cuddly with our closest star is called perihelion. "Peri" means near and "Helios" was the Greek god of the sun. … Read more

We already know how to explore planets with relatively low gravity, like Mars. The Curiosity Rover is engineered to hang onto the planet's surface, despite it having just 38 percent of the gravity we enjoy on Earth. What happens if you want to check out a small moon or an asteroid with a fraction of that gravity? You design a robotic hedgehog, of course.

Stanford University researchers and NASA are working together on spiky space balls that could dance across the surfaces of moons and asteroids whose low gravity and rough surfaces would bog down a regular rover. … Read more

The moon could have some serious competition in 2013.

No, we're not finally building a real Death Star, no matter how much the American people demand one. I'm talking about a surprise visit from a recently discovered heavenly body known as the comet Ison. The chunk of ice and rock has likely broken free from the Oort cloud and is heading our way right now. If it survives the journey, astronomers say it could become even brighter than our lunar neighbor in the night sky as it makes a pass through our neighborhood next fall.

According to NASA, the wayward comet is currently hurtling toward the sun somewhere in the vicinity of Jupiter's orbit. By October, it should come very near Mars, possibly allowing NASA's rovers a view as it shakes its tail in their direction. From there, it appears it will continue toward the center of the solar system, passing within a single solar diameter of the sun's surface before heading back more or less the way it came. … Read more

The Mars Curiosity rover recently detected signs of organic compounds on the Red Planet, but NASA won't call the findings definitive. One holdup is the issue of contamination. The trace amounts may be the result of contamination from the rover itself.

The contamination issue could rear its head again should the rover or future expeditions turn up any microbes. Finding microbes on Mars would be a cause for scientific celebration, but a study published in "Proceedings of the National Academy of Sciences of the United States of America" shows that Earth microbes could very well survive in the brutal conditions on Mars.… Read more

Around 2015, NASA plans to incorporate a spacesuit that amusingly looks like the one worn by Buzz Lightyear in "Toy Story" -- sans the shiny laser beam.

Before you laugh, know that these new digs aren't toy dressings; the Z-1 NASA spacesuit offers a plethora of advantages compared with the space agency's previous designs. Think of it as the baseline architecture for future NASA spacesuits. … Read more
