writes with this news from the BBC: The European Space Agency (ESA) says its comet lander, Philae, has woken up and contacted Earth. Philae, the first spacecraft to land on a comet, was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November. It worked for 60 hours before its solar-powered battery ran flat. The comet has since moved nearer to the sun and Philae has enough power to work again, says the BBC's science correspondent Jonathan Amos. An account linked to the probe tweeted the message, "Hello Earth! Can you hear me?"

: From the ESA's Rosetta blog:When analysing the status data it became clear that Philae also must have been awake earlier: "We have also received historical data - so far, however, the lander had not been able to contact us earlier," [according to project manager Dr. Stephan Ulamec.] Now the scientists are waiting for the next contact. There are still more than 8000 data packets in Philae’s mass memory which will give the DLR team information on what happened to the lander in the past few days on Comet 67P/Churyumov-Gerasimenko.

On April 1, Bruce Schneier announced
his eighth Movie-Plot Threat Contest
; this time around, he asked for a story that showed the evils of encryption, and found a winner
in a story that describes an untraceably encrypted U.S. election in the year 2020 -- the first American election to allow on-line voting -- which results in victory for an unexpected third-party candidate.Read Replies (0)

New submitter garyisabusyguy
writes with word that, according to London's Sunday Times, "Russia and China have cracked the top-secret cache of files
stolen by the fugitive US whistleblower Edward Snowden, forcing MI6 to pull agents out of live operations in hostile countries, according to senior officials in Downing Street, the Home Office and the security services," and suggests this non-paywalled Reuters version
, too. "MI6 has decided that it is too dangerous to operate in Russia or China," writes the submitter. "This removes intelligence capabilities that have existed throughout the Cold War, and which may have helped to prevent a 'hot' nuclear war. Have the actions of Snowden, and, apparently, the use of weak encryption, made the world less safe?"Read Replies (0)

writes with the news that the European Space Agency may have located
the agency's Philae
lander. The official Rosetta blog says Fortunately, it was possible to narrow down the lander’s final location by using the radio signals sent between Philae and Rosetta as part of the CONSERT experiment after the final touchdown. Combining data on the signal travel time between the two spacecraft with the known trajectory of Rosetta and the current best shape model for the comet, the CONSERT team have been able to establish the location of Philae to within an ellipse roughly 16 x 160 metres in size, just outside the rim of the Hatmehit depression.
That means just a few candidates for Philae's current location, based on imaging performed by Rosetta's OSIRIS camera
