NASA's New Lunar Rover, Now Testing In Arizona 59

Posted by timothy from the detatchable-p-suit dept.
MarkWhittington writes "NASA has unveiled a new prototype lunar rover, called the Chariot, a production version of which is hoped to be operational on the lunar surface by 2019. NASA is now testing the Chariot lunar rover in Arizona, on terrain that resembles the lunar surface." Perhaps Arizona's an even closer match to the moon's surface than is Texas, or Moses Lake, WA where NASA was testing the last time we mentioned Chariot. (Here's a bit of video from the Texas round.)

First Secure Quantum Crypto Network Up and Running 102

Posted by timothy from the all-new-perfect-forever-place-your-bets dept.
John Lam was one of many readers to send in news that on Thursday, "at a conference in Vienna, Austria, as reported by the BBC, a European Community science working group built a quantum backbone using 200-km of standard commercial optical fiber running among seven sites and successfully demonstrated the first secure quantum cryptographic key distribution network. In addition, each of the seven links used a different kind of quantum encryption, demonstrating interoperability between the technologies. To paraphrase, the project focused on the trusted repeater paradigm and developed an architecture allowing seamless integration of heterogeneous quantum-key distribution-link devices in a unified framework. Network node-modules managing all classical communication tasks provide the underlying quantum devices with authentic classical channels. The node-module architecture uses a layered model to provision network-wide, end-to-end, provably secure key distribution."

Free Online Scientific Repository Hits Milestone 111

Posted by CmdrTaco from the a-whole-lotta-smart-stuff dept.
ocean_soul writes "Last week the free and open access repository for scientific (mainly physics but also math, computer sciences...) papers arXiv got past 500,000 different papers, not counting older versions of the same article. Especially for physicists, it is the number-one resource for the latest scientific results. Most researchers publish their papers on arXiv before they are published in a 'normal' journal. A famous example is Grisha Perelman, who published his award-winning paper exclusively on arXiv."

About two years ago, i visited my parents at home during the summer holidays. One morning i stood in front of our house and looked at the city of Lindau, Germany. And suddenly i saw a silverish cigar in the sky above the city like i had seen it on many ancient photos. That moment i knew i had seen a modern Airship for the first time.
They are building this Airship in Friedrichshafen, a town at the lake of constance where they also built most of the great Airships of our century, including the Hindenburg. And this Airship has the same name as all his ancient brothers: ZEPPELIN.

for further information take a look at the hompage of "Zeppelin Luftschifftechnik GmbH".
