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 10:54pm Monday 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 1:22pm 6/18/15 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 12:14pm 4/30/15 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 2:22pm 3/25/15 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 11:00am 1/27/15 11:00am

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

18

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 10:23pm 1/23/15 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 11:01am 1/07/15 11:01am

We Found a New and Cheaper Way to Get to Mars

There are myriad reasons why getting from Earth to Mars is hard, but chief among them are two 1) the massive amount of fuel needed and 2) a launch window that is limited to every 26 months, when the two planets are in optimal alignment. A couple of mathematicians have calculated a new path to Mars that solves both—and… » 12/23/14 4:25pm 12/23/14 4:25pm

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 4:00pm 12/07/14 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 12:30pm 12/02/14 12:30pm

Why We Should Keep Trying to Time Travel

H.G. Wells coined the term "time machine" all the way back in 1895, just a decade before Einstein published his groundbreaking paper on special relativity that would begin show how time travel is possible. The fascination with using technology to look into the past or the future hasn't faded in the last century. And… » 11/20/14 10:03am 11/20/14 10:03am

The Futuristic Technology That Could Enable Interstellar Travel

Technically savvy scientists and engineers have put much effort into conceiving far-future technologies that might make possible near- light-speed travel. You can learn a lot about their ideas by browsing the web. It will take many centuries for humans to make any of those ideas real, I think. But they do convince… » 11/14/14 2:08pm 11/14/14 2:08pm

Yes, Time Travel Is Possible; Here's How

Time travel's been one of man's wildest fantasies for centuries. It's long been a popular trend in movies and fiction, inspiring everything from Charles Dickens' A Christmas Carol to H.G. Wells' The Time Machine to the Charlton Heston shrine that is The Planet of the Apes. And with the opening of Interstellar » 11/05/14 1:25pm 11/05/14 1:25pm

Why Space Travel Matters More Than Ever

Yesterday, somewhere in the Mojave desert, investigators began the long process of understanding the events that led to the tragic accident that killed one pilot and left another injured. And even after they finish, plenty of questions about the future of the commercial space industry will remain. But the one we'll… » 11/01/14 10:26am 11/01/14 10:26am

Kraft Foods Gave Away a Real Spaceship Simulator in 1959

If you were an American kid in the 1950s and 60s you were bombarded with an amazing promise: one day, when you're all grown up, you'll be able to vacation on the moon. But until then you'll have to settle for space-adventure TV shows and comic books. Unless, of course, you won this real live space simulator from 1959. » 10/23/14 3:29pm 10/23/14 3:29pm

Wernher von Braun Predicted We'd Send Men to Mars No Sooner Than 2050s

Student researchers at MIT have concluded that given current technology, any colonists to Mars would die after about 68 days. Mars One, the company that hopes to put people on Mars by the 2025 (and film a reality TV show there, so you know they're legit) insists that the MIT researchers are wrong. But as any student… » 10/15/14 1:20pm 10/15/14 1:20pm
