Yesterday, Stephen Hawking and Yuri Milner made the mind-blowing announcement that they want to build a fleet of interstellar spacecraft that can travel at relativistic speeds—up to 20 percent the speed of light. But it’s not just about reaching our nearest star system, Alpha Centauri, although that is the new…
It’s an exciting time to be alive if you’re keen to watch humans get off this planet. A private space race is taking off, opening new pathways to orbit while sparking a burst of technological innovation. Even better, thanks to the magic of internet live streaming, we’re watching history unfold in real time.
The ironic thing about living in space is that you spend all of your time crammed into a tiny tin can. So the brave men and women at the International Space Station are probably stoked about what’s headed their way next month: a spare room.
If an asteroid were closing in on our planet, we’d know about it quickly thanks to a dedicated network of astronomers. But this week, the Near Earth Object Coordination Center (NEOCC) had its eyes fixed on something else: two Mars-bound spacecraft attempting to escape Earth’s gravity well. And they did a bang-up job…
If the thought of turning your gaze to a TV screen for election news this evening makes you want to vomit, then you might have some empathy for what two men will feel as they plummet toward the ground from 250 miles on high in a fiery metal can at a rip-roaring 17,000 miles per hour.
As America braces itself for another seven months of bickering over which suited flesh puppet most deserves to lead our country for the next four years, 250 miles up, a much more civilized transfer of power is taking place today.
We’re all looking forward to interstellar travel and colonizing Mars, but first, we’ve got a lot to learn about how the human body responds to the cold dark void of outer space. Scott Kelly’s stint on the ISS, which ends tomorrow, is helping us answer some critical questions—including what weightlessness does to our…
It’s been a few really good months for SpaceX, and now, the commercial spaceflight company is kicking rocket production into high gear in anticipation of a packed launch schedule.
Philae, the brave little comet lander that captured our hearts last year, has probably fallen silent for good. After a final, desperate effort to contact the spacecraft over the weekend didn’t pan out, the German Aerospace Agency (DLR) reports that the chances of ever speaking to the probe again are slim—and they’re…
Right on schedule, SpaceX’s Falcon 9 booster made a beautiful soft landing at Cape Canaveral Air Force Station moments ago. It’s a huge moment in the history of spaceflight, marking the first time a rocket has ascended into orbit and landed back on Earth.
Are you ready to watch SpaceX try to make history with a bold attempt to send its souped-up rocket all the way into space and back to Earth in a spectacular nighttime launch? Of course you are!
In its ongoing effort to bring America back into the crewed spaceflight game, NASA announced today that Boeing has received a second commercial crew order to ferry astronauts to the International Space Station.
Six months after a rocket exploded in June, SpaceX is on the verge of taking to the sky again—with a souped up Falcon 9 booster more powerful than anything the commercial spaceflight company has ever launched.
In two years, SpaceX will begin ferrying astronauts into orbit. But before it can do so, the commercial spaceflight company must prove to NASA that its ride will be safe. A big part of that guarantee comes from the fire-breathing propulsion system pictured above.
In a major step forward for crewed commercial spaceflight, NASA has contracted private rocket company SpaceX to blast astronauts off US soil beginning in 2017.
What happens to your brain when you have no sense of up? Researchers are scanning the brains of astronauts to track just how badly space messes with our ability to think.
Hard to believe, but it’s been one year since SpaceShipTwo disintegrated during a test flight, killing one pilot and seriously injuring the other. Undaunted by the tragedy, Virgin Galactic has been hard at work building the second version of the suborbital rocket plane—a slightly modified version that may finally…
One minute you’re fooling around in a couple of short-lived space stations that stumble into the atmosphere and burn up, the next you’ve spent a decade and a half with continuous habitation of a major International Space Station. Time flies when you’re outside the gravity well!
September 9, 2015: The Soyuz TMA-18M spacecraft arrived at the International Space Station for a ten-day mission, providing visual proof of a little bit of every day magic: in space, “up” is optional.
