Obama Dreams of Space, But Where's the Money for a Mars Expedition?

During the State of the Union address, President Obama said stirring things about human spaceflight and the future. But these are the same dreams we've been talking about for years, and without more funding for NASA these dreams will fizzle instead of coming true. » 1/20/15 11:45pm 1/20/15 11:45pm

A Daring Asteroid Mission Kicks Off After Weather Delays

Japan's space agency just launched Hayabusa 2, an ambitious deep space mission to land on an asteroid, smack it with an interceptor, collect and return samples, and deploy rovers.

Here's A Thirty-Year History Of Getting Closer To Comets

Rosetta's lander Philae is warming up to land on comet 67P/Churyumov-Gerasimenko in just a few hours. It will be our first-ever attempt at touching down on a dirty chunk of ice in space. But how close have we gotten to a comet before? » 11/11/14 1:16pm 11/11/14 1:16pm

Stock Up On Spirulina For Snacks and Fresh Air On Deep Space Missions

Meet Spirulinaha, Arthrospira bacteria that scrubs carbon dioxide into oxygen, is a protein-rich meal for astronauts, and multiplies so rapidly that eating them for dinner won't leave the space station without fresh air by morning. » 9/01/14 3:15pm 9/01/14 3:15pm

Here's Why You Should Be Excited About The James Webb Space Telescope

Peter Cullen, voice of Optimus Prime, recently lent his legendary voice to a slick animated introduction to the successor of the ridiculously prolific Hubble Telescope, NASA's James Webb Space Telescope.

10 Words You Might Think Came from Science (But Are Really From Science…

Last week it came to our attention that the phrase "blast off" was coined—not in a purely scientific context, but a science fictional one—by E. E. Smith, an early science fiction author often referred to as "the father of space opera." The term appeared in Smith's 1937 story Galactic Patrol, when one character… » 10/17/11 10:00am 10/17/11 10:00am

Satellite Goes Down, Buck Rogers Not Reporting In

It looks like the U.S. Navy was able to pull off a real-life game of missile command last night, and successfully shot down our ailing superspy satellite while everyone was busy gawping at the lunar eclipse. Hey, that's exactly how the script for the failed reboot of Buck Rogers began... does that mean we just sent a… » 2/21/08 1:30pm 2/21/08 1:30pm

A Gallery of Freakish Galaxies

It's the best kind of space picture: a collection of bizarre galaxies with freakish shapes. Who cares about those boring spiral arm galaxies when you can have the smooshed ass galaxy, or two galaxies crashing into each other? These misshapen beauties were captured by a research consortium called AEGIS, which just… » 10/03/07 2:22pm 10/03/07 2:22pm
