How Traveling to Deep Space In Cryogenic Sleep Could Actually Work

Our bodies aren’t meant for space. We require too much maintenance to speed through the stars. We need a steady supply of things absent from space — namely water, food and oxygen. We crave warmth but won’t find it in deep space, where the average temperature is -455 degrees Fahrenheit. Even if we could survive in an… »8/21/15 3:15pm8/21/15 3:15pm

These Space Farmers of 1959 Were Way Ahead of Their Time

Earlier this week astronauts aboard the International Space Station ate fresh food grown in space for the first time. It’s an exciting accomplishment and will be crucial for the survival of the first crewed missions to Mars. But it’s been a long time coming, as we can see from this 1959 comic strip depicting the… »8/12/15 2:01pm8/12/15 2:01pm

In 1969, the Apollo 11 Astronauts Reunited With Their Families (Sort Of)

Neil Armstrong (blowing a kiss to his sons) is flanked by Michael Collins and Buzz Aldrin on July 27, 1969 at Ellington Air Force base in Houston, Tex. On July 24, the Apollo 11 astronauts returned from their historic trip to the moon, but due to infection fears, they were quarantined for 21 days. »7/27/15 10:54pm7/27/15 10:54pm

6 Horrible and Doomed Space Missions, Brought to You By Crowdfunding 

Government funding for space travel ain’t what it used to be. Private organizations are our best hope for exploring beyond Earth’s increasingly noxious atmosphere, and to get your cash they’re turning to Indiegogo and Kickstarter to fund ambitious space missions. Unfortunately, most of the projects are bonkers messes… »6/18/15 1:22pm6/18/15 1:22pm

New Test Suggests NASA's "Impossible" EM Drive Will Work In Space

Last year, NASA’s advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive, or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum. »4/30/15 12:14pm4/30/15 12:14pm

We Should Be Able To Detect Spaceships Moving Near The Speed Of Light

A pair of engineers say it's possible to detect the signatures of spacecraft traveling at relativistic speeds, and we can do so using current technologies. The trouble is, their new analysis also suggests that moving through space at ludicrous speed is more hazardous than previously thought. »3/25/15 2:22pm3/25/15 2:22pm

Which Religions Are Prepared to Accept Life in Space?

Assuming we don't blow ourselves up before then, colonizing other planets may be the last hope for the survival of humanity. Most of the preparation for this cosmic expansion has centered around solving the more immediate, physical problems of transporting our bodies into deep space, but what about our culture?… »1/27/15 11:00am1/27/15 11:00am

After Earth Falls, Will Interstellar Space Travel Be Our Salvation?


It may be just a matter of time before the Earth becomes uninhabitable. As astrophysicists and avid science fiction fans, we naturally find the prospect of interstellar colonization intriguing and exciting. But is it practical, or even possible? Or is there a better solution? »1/23/15 10:23pm1/23/15 10:23pm

NASA Made These Gorgeous Travel Posters For Actual Exoplanets

As the exoplanet discoveries from Kepler keep pouring in, we're realizing just how fantastic, bizarre, and varied the planets of our universe truly are. Someday, we might see them with our own eyes. NASA's Jet Propulsion Laboratory has created a stunning set of exoplanet travel posters that will make you wish very… »1/07/15 11:01am1/07/15 11:01am

A Brief History of Space Travel as Told by the Art That Inspired It

Humanity has been obsessed with exploring the stars for millennia, it just took a little while for us to obtain the means of actually doing so. In his new book, The Art of Space, author Ron Miller explores both how we developed the technology necessary for space travel and how that technology has steadily migrated… »12/07/14 4:00pm12/07/14 4:00pm

We're Running Out of the Nuclear Fuel That Powers Space Travel

Rosetta's lander lasted just 60 hours on a comet after it bounced into the dark shadows of a cliff, where its solar panels couldn't power the vehicle. Why didn't it carry a more reliable power source, say a nuclear battery like one that's unfailingly fueled Voyager for decades? It's a simple question with a… »12/02/14 12:30pm12/02/14 12:30pm
