NASA may have its sights set on Mars, but before it can send astronauts to the Red Planet it needs to hone its skills with long-distance, long-duration human spaceflight beyond low-Earth orbit. Enter the “missing link” in exploration evolution: the Asteroid Redirect Mission, or ARM, NASA’s plan for developing the technology and experience for Mars while learning…

What Will We Name the Features on Pluto? You Decide.
This July the New Horizons spacecraft will perform its long-awaited flyby through the Pluto system, capturing unprecedented data and images of the distant icy planet and its companion satellites Charon, Nix, Hydra, Kerberos, and Styx. The first two worlds, in particular, will have their surfaces seen in high-resolution, allowing scientists to observe and map their features…
Curiosity Has Found Yet More Evidence For a Life-Lovin’ Mars
Cold as hell and no place to raise your kids, the surface of Mars today is a quite inhospitable place for any forms of life we know of. But that wasn’t always the case – billions of years ago Mars may have been a lot more like Earth, with a magnetic field, a much denser atmosphere, lakes…
No Signal Yet From Philae (But ESA Isn’t Giving Up)
The first attempt by ESA and Rosetta to hear back from Philae has turned up only radio silence – but that doesn’t necessarily mean the lander is on permanent shutdown. It may just be that it’s still too cold and dark where Philae is to have sufficiently warmed up its components for reactivation. “It was…
MarsOne CEO Responds to Claims of Conspiracy and Fraud
The suffix “-gate” is often added to words to create a meaning of conspiracy or public debacle, à la the 1972 Watergate scandal that destroyed Nixon’s term as U.S. president, and we might soon be referring to this as “Marsgate” – the allegations of MarsOne of illegitimacy and fraudulent (or at the very least sketchy) practices…
NASA’s MAVEN Spacecraft Spots Mars’ Secret Invisible Aurora
Only a day after skywatchers in mid- to upper-latitudes around the world were treated to a particularly energetic display of auroras on the night of March 17 as a result of an intense geomagnetic storm, researchers from the University of Colorado announced findings from NASA’s MAVEN mission of auroral action observed on Mars – although in invisible ultraviolet wavelengths rather than visible…
This is What it Would Look Like to Fight Flying Dragons on Titan
Obviously this is a totally-for-fun sci-fi video, but what a video! Created by Oscar-nominated Irish filmmaker Ruairi Robinson, it shows fleets of very industrial-looking fighter skiffs hunting giant flying eels through the skies of some very cloudy planet… the first thought that came to my mind was Titan! (Although Titan is more hazy than cloudy…
Closing In on Planet Pluto: an Interview with New Horizons PI Alan Stern
After more than nine years of traveling through space the New Horizons spacecraft is now in the home stretch of its journey, with less than 120 days and 143 million kilometers to go before it makes its historic flyby of the Pluto system on July 14. It will be the first time we get a good close-up look…
Ground-Based Radar Reveals the Surface of Venus
These days if you look toward the west after sunset you’ll see a bright star that’s the first to appear in the sky – except it’s not a star at all but our neighboring planet, Venus. Covered in a dense layer of thick clouds, Venus not only reflects a lot of sunlight but also keeps its…
Ganymede’s Aurorae Hint at an Ocean Ten Times Deeper than Earth’s
It’s long been suspected that Jupiter’s giant moon Ganymede may harbor a subsurface ocean of liquid water beneath its icy yet hard-as-rock crust, and now some ingenious observations with the Hubble Space Telescope are making an even more convincing case for it!
The Next Chapter of Philae’s Big Adventure is Here!
If you’ve been following the animated adventures of Rosetta and Philae from the European Space Agency you may have been wondering when the next episode of Philae’s big adventure would be coming. Well it’s here, and you can find out (again) what happened to the little lander on November 12, 2014 when it made its…
What is a Neutron Star, Anyway?
Neutron stars are strange cosmic beasts. Stellar corpses that are several times the mass of our Sun but only about the width of Manhattan, they can contain a mountain’s worth of star-stuff within the space of a sugar cube, creating all sorts of weird physics that requires funny-sounding names like “quark-gluon plasma” to even try to describe what’s…
