NASA's LLCD tests confirm laser communication capabilities in space

This week, NASA released the results of its Lunar Laser Communication Demonstration’s (LLCD) 30-day test carried out by its Lunar Atmosphere and Dust Environment Explorer (LADEE) that is currently in orbit around the Moon. According to the space agency, the LLCD mission proved that laser communications are practical at a distance of a quarter of a million miles and that such a system could perform as well, if not better, than any NASA radio system.Read More

Cities reimagined as cellular dreamscapes

Nickolay Lamm is a self-identified artist and researcher, who is making a career of transforming ordinary images into extraordinary visual displays of quantitative information, to borrow from Ed Tufte. We take a look at his transformation of New York, Chicago, Hollywood, and Washington D.C. through converting cellular network transmissions into visual overlays.Read More

LADEE sets data transmission record from lunar orbit

NASA’s Lunar Laser Communication Demonstration (LLCD) experiment made history yesterday as it beamed data back to Earth from lunar orbit at previously unheard of speed for a space mission. Operating from the LADEE lunar orbiter, the LLCD used lasers to transmit data to Earth at 622 megabits per second (Mbps) as a demonstration of a technology that NASA hopes will one day not only keep up with the communications demands of future missions, but also greatly enhance their capabilities.Read More

Ford and GM team up on fuel-saving 9- and 10-speed transmissions

Over the course of the past several years, German manufacturer ZF Friedrichshafen has introduced 8- and 9-speed transmissions. Vehicle models from the likes of Chrysler and Land Rover have made use of the new hardware, touting fuel economy gains and other advantages. Now, the other two major Detroit auto manufacturers are teaming up to develop 9-speed transmissions of their own, and they're taking it one step further: 10-speed transmissions. Read More

Pinion sealed gearbox offers an alternative to those darn derailleurs

Rear derailleurs are problematic, particularly on mountain bikes. They get bent, they get gunked up, and they’re exposed to the elements. While sealed hub transmissions lack these problems, not all of them have axles that are strong enough for multi-terrain use, they add revolving weight, and that weight is added in the back of the bike – not low and in the middle, where you want it. German company Pinion has developed what it claims is something better ... a sealed gearbox located adjacent to the bottom bracket. Read More

Land Rover introduces first 9-speed automatic gearbox

Land Rover has announced that it will demonstrate the world's first nine-speed automatic transmission for a passenger car at the 2013 Geneva Motor Show. The ZF HP9 9-speed gearbox has a higher top gear in a more compact design, in order to fit in the same space as conventional 6-speed transmissions. According to Land Rover, it will also provide smoother gear shifts with improved accelerations and lower fuel consumption.Read More

GM's TapShift technology shows why automatic transmissions may soon replace manuals

The 2012 Chevy Camaro ZL1 - the most powerful production Camaro ever - will make use of the latest iteration of TapShift technology. This automated transmission option allows drivers to move through gears using paddle shifters. The updated 2012 TapShift system creates faster shifts, that make the automatic Camaro quicker to 60 mph ( 96.5 km/h) than the manual version. While the transmission choice for a muscle car as fast and powerful as the ZL1 would traditionally have been obvious in the past (manual all the way), GM's updated TapShift technology makes a strong case for the automatic.
