A new bill making its way through the U.S. House of Representatives wants to take a sledgehammer to the future of space travel for the benefit of one corporation.

The long-debunked story of NASA buying ridiculously expensive pens is just too gratifying for some people to pass up.

The space exploration industry is booming, which is an encouraging sign for our future. But some pundits are arguing that rocket launches will exacerbate global warming.

After decades of neglect, space agencies are starting to listen to planetary scientists interested in studying Venus. Here's why they want to explore an alien hellscape.

If you want to explore our solar system, you need to prepare for multi-year journeys. But a new discovery in nanoscale engineering could help cut the travel time between worlds.

NASA appears to be sick and tired of having to wait until the mid-2020s to return to the Moon on a future rocket that will be inferior to the private ones already flying, and easily lapped by ones currently being built.

It may be tempting to use our nuclear warheads to save the planet from rogue space rocks instead of pointing them at each other, it would be a waste of perfectly good nukes.

Now that Opportunity's mission is complete, many wistfully lament about "bringing our robot home." There's just one problem: it's already home.

Buckle up steampunk enthusiasts, it turns out that not only are steam-powered space probes possible, they might be perfect for hopping between comets and asteroids on research and mining missions.

Super-Earths are often thought of as just bigger version of our own planet on steroids. But these worlds offer us amazing insights into everything from plate tectonics to planetary formation and classification.

Mars One was an impossible dream. No, literally. As in not possible and could never happen. Now the company is bankrupt and its mission plans abandoned, which is really for the best.

Paradoxically, we're both closer and farther from zooming across the galaxy than you might think…

A recent paper imagines a new explanation for the strange motions of Trans-Neptunian Objects observed by astronomers for the last 200 years, but it doesn't mean that we won't still search for Planet Nine.

New models trying to infer the geology of potentially habitable moons orbiting Jupiter and Saturn hint at surprisingly cool, geologically inactive worlds, the opposite of what a diverse alien ecosystem would need.

Sci-fi Saturday returns with what will be part one of a short story...
