From bridges to cars, 3D printing proved this year that it’s still relevant and exciting. The hype may have died down a little, but 3D printing was still creating waves in manufacturing in 2018. On the important-but-boring side, manufacturing companies are using the tech for things like weight reduction and cost savings. More interestingly, […]

From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25. An international team of 32 authors from 24 institutions in eight countries led […]
They’ve awarded cash prizes as part of an ongoing competition. NASA has selected five winners in an ongoing contest it has been running to get smart ideas about how to build a 3d-printed habitat on Mars. The winners have passed level one of the 3D-Printed Habitat Centennial Challenge, which required developing about 60 percent of […]
Can gardens help astronauts go farther? “Our plants aren’t looking too good,” astronaut Scott Kelly tweeted from the International Space Station on December 27, 2015. He was right: The attached picture showed four baby zinnias bathed in magenta light. Three of the four leafy stalks were discolored and curling in on themselves. The station’s garden […]
Despite the increasing role of private companies in space exploration, most believe NASA’s role is still vital for future. Sixty years after the founding of the National Aeronautics and Space Administration (NASA), most Americans believe the United States should be at the forefront of global leadership in space exploration. Majorities say the International Space Station […]
The first independent tests of the EmDrive suggest there’s a mundane explanation for the wildly controversial device. Spaceflight is hard. Blasting heavy cargo, spacecraft, and maybe people to respectable speeds over interplanetary distances (not to mention the luxury of stopping at destinations) requires an amount of propellant too massive for current rockets to haul into […]
After spending nearly a year aboard the International Space Station, American astronaut Scott Kelly returned to Earth in 2016—only to find that his DNA had changed.
WASHINGTON (Reuters) – Initial tests in Nevada on a compact nuclear power system designed to sustain a long-duration NASA human mission on the inhospitable surface of Mars have been successful and a full-power run is scheduled for March, officials said on Thursday.
The slope rises as high as London’s Big Ben tower. Beneath its ruddy layer of dirt is a sheet of ice 300 feet thick that gives the landscape a blue-black hue. If such a scene sounds otherworldly, it is. To visit it, you’ll have to travel to Mars.
Right now, private companies and NASA have a nice, functional, symbiotic capitalist relationship. SpaceX and its competitors build and will soon operate the vehicles, while NASA pays for the service. But with Elon Musk’s eyes tilted toward Mars, that won’t last for long.
