Comment Re:Exponential debris spread (Score 2) 225

Mod parent up!
So, a 1-5 mm piece of debris caused a hole 40cm, i.e. 400mm wide - probably creating hundreds or thousands of pieces of new debris. Since the satellite is in the crowded low earth orbit (apogee 693km), perhaps the chance of it hitting a piece of its own solar panel in the future is probably now higher than "1:35 and 1:130", though those bits would not be traveling quite as (relatively) fast as the original impact.

Apparently this exponential debris effect is called the Kessler_syndrome

Comment Once a year in Belgium (Score 1) 222

In Belgium, many towns have been doing this once a year since 2008 or earlier: it's called Nacht van de Duisternis / La Nuit de l'Obscurité.

Besides startgazing and awareness, there are many activities including guided walking tours to learn about nocturnal animals (and the effect light has on them).

Comment Fon Fonera (Score 1) 344

How about flashing OpenWrt/dd-wrt on the Fon Fonera (http://www.fon.com)? I have an Asus WL-500G v1 running OpenWrt and an Asus WL-500W still running stock firmware (but purchased with the intent to install OpenWrt, if necessary), but the Fonera seems quite interesting too.

The Best Robots of 2009 51

kkleiner writes "Singularity Hub has just unveiled its second annual roundup of the best robots of the year. In 2009 robots continued their advance towards world domination with several impressive breakouts in areas such as walking, automation, and agility, while still lacking in adaptability and reasoning ability. It will be several years until robots can gain the artificial intelligence that will truly make them remarkable, but in the meantime they are still pretty awesome."

NASA and Space Station Alliance On Shaky Ground 73

coondoggie writes "Even as the latest shift of astronauts arrived at the International Space Station, challenges with the orbital outpost on the ground are threatening its future. Those challenges include the pending retirement of the space shuttle but also the way NASA and the ISS are managed. A report issued this week by the Government Accountability Office said NASA faces several significant issues that may impede efforts to maximize utilization of all ISS research facilities."
