Making light work of orbit and attitude control
Microsatellites have to be very light – every gram counts. The same applies to the gyroscopes used to sense the satellite's orientation when in orbit. A novel prototype is seven times lighter and significantly ...
Fastest rotating man-made object created
(Phys.org) —A team of researchers at the University of St Andrews has created the world's fastest spinning man-made object.
Important step forward for gait analysis of horses
Horses who develop a limp are one of the major sources of frustration for horse owners as well as vets. The same applies for Wobblers disease (ataxia) where growth abnormalities or articular process joint ...
Pulsars make a GPS for the cosmos
(Phys.org) —CSIRO scientists have written software that could guide spacecraft to Alpha Centauri, show that the planet Nibiru doesn't exist … and prove that the Earth goes around the Sun.
NASA gives up fixing Kepler planet-hunting telescope
NASA called off all attempts to fix its crippled Kepler space telescope Thursday. But it's not quite ready to call it quits on the remarkable, robotic planet hunter.
Swapping motion-sensing units
(Phys.org) —NASA's Mars Reconnaissance Orbiter is switching from one motion-sensing device to a duplicate unit onboard.
The robot and its virtual twin (w/ Video)
It walks, falls, and gets up on his own, follows a ball by sight and shoots. It also knows how to do many other things. The small humanoid robot DARwIn-OP was developed by a Korean company and three U.S. universities to serve ...
Novel hollow-core optical fiber to enable high-power military sensors
The intensity of light that propagates through glass optical fiber is fundamentally limited by the glass itself. A novel fiber design using a hollow, air-filled core removes this limitation and dramatically ...
China astronauts float water blob in kids' lecture
Astronauts struck floating martial arts poses, twirled gyroscopes and manipulated wobbling globes of water during a lecture Thursday from China's orbiting space station that's part of efforts to popularize ...
Kepler spacecraft's breakdown changes NASA mission's course
Crippled in space, the Kepler spacecraft's planet-hunting days are likely over. But its discoveries may be yet to come.
(Phys.org) —Eight hundred and eighty nine exoplanets (planets around stars other than our Sun) have been discovered to date. Most of them were found using the Kepler satellite, which spots small dips in ...
Scaling up gyroscopes: From navigation to measuring the Earth's rotation
Accurately sensing rotation is important to a variety of technologies, from today's smartphones to navigational instruments that help keep submarines, planes, and satellites on course. In a paper accepted for publication ...
US army seeks new technology to replace GPS
The US army is working to limit its dependence on GPS by developing the next generation of navigation technology, including a tiny autonomous chip, the director of the Pentagon's research agency said Wednesday.
Wearable electronics move on from iPhone, to iWatch and beyond
You can wear your heart on your sleeve. Why not your electronics? In a burgeoning trend that has captivated Silicon Valley, a mind-boggling array of "wearable electronics" has begun to arrive, not just at a website or clothing ...
