From Engadget: Pioneering astronaut Neil Armstrong dies at 82

Pioneering astronaut Neil Armstrong dies at 82

It’s a story that we hoped we’d never have to report. Neil Armstrong, the first man to set foot on Earth’s Moon, has died at the age of 82 after complications from heart surgery three weeks earlier. His greatest accomplishment very nearly speaks for itself — along with help from fellow NASA astronauts Buzz Aldrin and Michael Collins, he changed the landscape of space exploration through a set of footprints. It’s still important to stress his accomplishments both before and after the historic Apollo 11 flight, though. He was instrumental to the Gemini and X-series test programs in the years before Apollo, and followed his moonshot with roles in teaching aerospace engineering as well as investigating the Apollo 13 and Space Shuttle Challenger incidents. What more can we say? Although he only spent a very small portion of his life beyond Earth’s atmosphere, he’s still widely considered the greatest space hero in the US, if not the world, and inspired a whole generation of astronauts. We’ll miss him.

From Popular Science – New Technology, Science News, The Future Now: Video: A Real Working Hoverbike Zooms Across the Desert

Tandem-Duct Aerial Aerofex

Future tech doesn’t always look the way the ’70s might’ve predicted, but sometimes it does. Case in point: this beautiful, fully functional hoverbike that could’ve been torn out of our archives. It’s going to be a while before you see one zipping down the street, but if the public does get a chance to ride one, the bike is rideable right out of the box–no training required.

Brought to you by aerospace firm Aerofex, the bike runs on a pair of powerful fans. It picks up on instinctive movements people make while riding a bicycle or motorbike, then moves in the same way (except, you know, flying), meaning anyone can have a go at it. For safety reasons, they’ve tested it at 30 mph and 15 feet high, although earlier versions of it went as fast as a helicopter.

Like all fun toys, the military will probably get this one first. The founders aren’t planning to make a manned version immediately, they told Innovation News Daily; instead they’re opting to use it as a test platform for creating hover drones.

But until we see it somewhere else, fight back your Star Wars speederbike dreams with this test run video, shot in the Mojave Desert.

From Engadget: MIT ‘microthrusters’ are the size of a penny, could reposition tiny satellites

MIT 'microthrusters' are the size of a penny, could reposition tiny satellites

Bus-sized satellites require massive engines for even the slightest movements, but as far smaller structures become a possibility, a tiny driving mechanism can offer usable thrust. To serve this next-gen tech, MIT saw a need to develop “microthrusters,” which are each the size of a penny and can be mounted to tiny cubed satellites. With thruster components measuring a few microns each, the magnetic levitation system is able to accommodate 500 microscopic tips that emit ion beams in a very small package, serving to push two-pound structures through space. The tiny devices have not made their way into orbit yet, but they have been tested in a vacuum chamber. Because of their size, it’s possible to add several to each satellite, then enabling sophisticated movements for more precise turns.

There are currently two dozen “CubeSats” in orbit, each measuring only slightly larger than a Rubik’s cube, but without any thrusters to power them, positioning can’t be adjusted once they’re released. Because of their current location, CubeSats eventually burn up in the atmosphere, but once they’re released farther from Earth, they won’t be able to enter the atmosphere on their own, remaining in orbit as “space junk” even after completing their missions — micro thrusters could also serve to move these satellites closer to the planet so they can burn up during re-entry. There’s no word on when, or even if, MIT’s invention will make its way to the launchpad, but you can take a closer look in the demo video after the break.
