CAPE CANAVERAL

635822407456257244-snc-cargo-dc-on-orbitCAPE CANAVERAL — Multibillion-dollar contracts NASA is expected to award as soon as Thursday will establish the fleet of U.S. vehicles servicing theInternational Space Station into the next decade, and could introduce a new spacecraft to Kennedy Space Center.              The space agency was scheduled to announce the winners of contracts to deliver cargo to the space station on unmanned craft between 2018 and 2024, decisions that have been delayed multiple times this year.The incumbent cargo haulers, SpaceX and Orbital ATK, hope to continue their services, while Boeing and Sierra Nevada Corp. hope to claim a piece of the action that could be worth up to $14 billion.                                                                                    For Sierra Nevada, which last year lost out to Boeing and SpaceX on contracts to fly astronauts, the cargo deals offer a second and perhaps last chance to bring the Dream Chaser mini-shuttle to life.

Augmented Reality Wizards Blippar Will Unveil New Tech At TechCrunch Disrupt London

What if you could learn about anything just by taking a photo of it?  Blippar already has 3 million people doing that every month plus another 62 million signed up. Now Blippar is ready to unveil the next phase of its technology and business, and it’s going to do it onstage at TechCrunch Disrupt London. Blippar CEO   Ambarish Mitra   is basically tech’s version of Slumdog Millionaire. After running away from home and living in the slums of Delhi, India, Mitra sold magazines door-to-door. But then he won $10,000 in an e-business plan competition and used the money to form an Internet portal for women that was free to those with low incomes. He eventually IPO’d that business, studied at the London School Of Economics, and sold his next business, Swiftcover, to AXA Insurance. Mitra started Blippar when augmented reality was just in its infancy. And while devices like the Microsoft HoloLens promise a future where we see digital graphics overlay information atop ou...

Now, turn 2D videos into 3D in a jiffy

By using a software that powers sports video games, researchers at the Massachusetts Institute of Technology (MIT) and the Qatar Computing Research Institute (QCRI) have developed a system that automatically converts 2D video of soccer games into 3D. The converted video can be played back over any 3D device -- a commercial 3D TV, Google's new Cardboard system which turns smartphones into 3D displays or special-purpose displays such as Oculus Rift. "Any TV these days is capable of 3D. There's just no content. So we see that the production of high-quality content is the main thing that should happen," says Wojciech Matusik, associate professor of electrical engineering and computer science at MIT. Today's video games generally store very detailed 3D maps of the virtual environment that the player is navigating. When the player initiates a move, the game adjusts the map accordingly and, on the fly, generates a 2D projection of the 3D scene that correspond...

World's Tiniest Engines Could Power Microscopic Robots

Scientists have created the world's tiniest practical engines, and these light-powered machines could one day power microscopic robots small enough to enter living cells, the researchers say. As  technological innovations   make devices smaller and smaller, scientists are developing machines that are only the size of complex molecules — nanometers, or billionths of a meter, in scale. In comparison, the average human hair is about 100,000 nanometers wide. One of the main reasons "nanobots" remain in the realm of science fiction is that figuring out a way to make them move has been challenging. Researchers have tried using a variety of power sources and propulsion systems for nanotechnology, but these typically lack speed, strength and control. [The 6 Strangest Robots Ever Created] "There have been many small machines, but they operate incredibly slowly — taking many seconds or minutes to move a single arm, for instance — and with very low forces," said...
