gbrumfiel writes "A meteor that exploded over Russia's Chelyabinsk region this morning was the largest recorded object to strike the earth in more than a century, Nature reports. Infrasound data collected by a network designed to watch for nuclear weapons testing suggests that today's blast released hundreds of kilotons of energy. That would make it far more powerful than the nuclear weapon tested by North Korea just days ago, and the largest rock to strike the earth since a meteor broke up over Siberia's Tunguska river in 1908. Despite its incredible power, the rock evaded detection by astronomers. Estimates show it was likely only 15 meters across — too small to be seen by networks searching for near earth asteroids." Today's meteor event came a day after California scientists proposed a system to vaporize asteroids that threaten Earth. Of course, the process needs to be started when the asteroid is still tens of millions of kilometers away; there's no chance to shoot down something that's already arrived.

NASA said the asteroid came "the closest-ever predicted approach to Earth for an object this large".

colinneagle writes "While Steve Jobs' ire in regards to Android is well known, a recent report from Reuters relays that current Apple CEO Tim Cook never wanted to sue Samsung in the first place. 'Tim Cook, Jobs' successor as Apple chief executive, was opposed to suing Samsung in the first place, according to people with knowledge of the matter, largely because of that company's critical role as a supplier of components for the iPhone and the iPad. Apple bought some $8 billion worth of parts from Samsung last year, analysts estimate.' In various earnings conference calls, Tim Cook has repeated that he hates litigation, but has still toed the party line by exclaiming that Apple welcomes innovators but doesn't like when other companies rip off their intellectual property."

New submitter dmfinn writes "While his union address covered a wide range of topics, President Obama made sure not to skip over the U.S.'s space program. The talking point was nearly identical to the one he gave in 2009, in which he called for space R&D spending to be increased past the levels seen during the the original cold war space race. Now, 4 years after that speach, it appears things have gone the opposite way. Since 2009 NASA has seen some serious cuts. Not only has the space-shuttle program been deactivated, but the agency was forced to endure harsh funding cuts during the presidents latter term. Despite an ominous history, it now seems that Obama is back on the space objective, pushing congress to increase non-defensive R&D spending to 3% of the U.S. GDP. It's important to keep in mind that not all of this money goes directly to space related programs, though under the proposed budget the National Science Foundation, Department of Energy Office of Science, and the National Institute of Standards and Technology Laboratories will have their budgets doubled. There will also be an increase in tax credits towards companies and organizations working on these R&D projects. Should the U.S. go back to its 'Let's put a man on the moon' ideology, or is the federal government fighting an uphill battle against newly emerging private space expeditions? Either way, the question remains whether or not Obama will act on any of the propositions."
