Check the landing video from the onboard camera - Guido: how well would our optical flow algorithm cope with such images? Looks quite complicated to me....

Note that videos there are said to be "thumbnail" quality, so I think videos with higher resolution (and possibly frame rate) have been acquired, just that they were not downloaded yet.

well, he kind-of falls into his own trap: confusing/discussing "evidence" with "likelihood", and "there is" with "it may". He should have made more efforts in his writing, what he says is a bit pointless! (just put the Icarus' paper)

interesting story with many juicy details on how they proceed ... (similarly interesting nickname for the "operation" chosen by our british friends) "The spies used the IP addresses they had associated with the engineers as search terms to sift through their surveillance troves, and were quickly able to find what they needed to confirm the employees' identities and target them individually with malware. The confirmation came in the form of Google, Yahoo, and LinkedIn "cookies," tiny unique files that are automatically placed on computers to identify and sometimes track people browsing the Internet, often for advertising purposes. GCHQ maintains a huge repository named MUTANT BROTH that stores billions of these intercepted cookies, which it uses to correlate with IP addresses to determine the identity of a person. GCHQ refers to cookies internally as "target detection identifiers." Top-secret GCHQ documents name three male Belgacom engineers who were identified as targets to attack. The Intercept has confirmed the identities of the men, and contacted each of them prior to the publication of this story; all three declined comment and requested that their identities not be disclosed. GCHQ monitored the browsing habits of the engineers, and geared up to enter the most important and sensitive phase of the secret operation. The agency planned to perform a so-called "Quantum Insert" attack, which involves redirecting people targeted for surveillance to a malicious website that infects their computers with malware at a lightning pace. In this case, the documents indicate that GCHQ set up a malicious page that looked like LinkedIn to trick the Belgacom engineers. (The NSA also uses Quantum Inserts to target people, as The Intercept has previously reported.) A GCHQ document reviewing operations conducted between January and March 2011 noted that the hack on Belgacom was successful, and stated that the agency had obtained access to the company's

I knew I wasn't using TOR often enough...

Cool! It seems that after all it is best to restrict employees' internet access only to work-critical areas... @Paul TOR works on network level, so it would not help here much as cookies (application level) were exploited.

Short range chemical analysis methods exist already, but using new high power lasers one could extend the operation length to e.g aircraft.

Isabelle?

The optical setup is very simple and lightweight: a compact semi-conductor DFB laser source and an all optical fiber system for amplification and supercontinuum generation. Interesting for space applications!

never seen a representation so accurate...

Let's start betting which party Aliens vote: GREEN, BLUE, RED, BLACK?

http://astrobiology.nasa.gov/ for the moment is down. My bet, the microbe they found notified its cousins and they are currently invading the US

you can still see the rest of it here: http://www.nasa.gov/multimedia/nasatv/index.html a good link with a summary and discussion on the announcement is here: http://www.guardian.co.uk/science/2010/dec/02/nasa-life-form-bacteria-arsenic

fantastic images!!! the footsteps of Apollo 14 are incredible!!

An educational movie on biomimetics. (german)

A preview of an educational movie on plant growth. Could be usefull for boom deflection.

1,2 million of this "fake" identical ny times were distributed today in the US

These guys from caltech work on a minituarized, automated microscope. Could be interesting for any type of human space exploration.

probably just for fun, but could be interesting to evaluate

videos on scienes - easier than reading the papers...

Nice Multimedia!

new game by NASA ... !

Another entry by the Planetary Society for the Apollo 11 50th anniversary, this time a podcast series on its political background.
