| Neil, tired but happy after the "walk" on the moon, in the Eagle lunar module still landed on the Moon |
Neil Armstrong is dead: Neil did not survive after complications of an operation on blocked coronary arteries, on 25 August 2012. The man that set the first step on the moon, announcing the famous line: "That's one small step for [a] man, one giant leap for mankind" survived 82 years, but did not live in the shadow of his big mission. Before working in space and going to the moon, he was between the top pilots in the world. After, he decided to teach in Cincinnati University, continuing to inspire young students into the wonders of aeronautics. The news of his death saddened not just the US, but the whole world.
Fermilab proposes plans for neutrino experiment: having served the world of particle physics thanks to its Tevatron, a proton-antiproton collider, Fermilab is proposing a new big experiment. Tevatron closed due to lack of funds and the advent of the bigger LHC at CERN, Geneva. Fermilab proposed a new neutrino experiment five months ago, which budget would have been 1.9 billion dollars. Due to the amount of money required, they were asked to rework their plans and on the 28th of August, they proposed a new plan, requiring only 789 million dollars. The new experiment would be called Long-Baseline Neutrino Experiment (LBNE) and would research on one of the most mysterious particles: neutrinos, its oscillations (between three of his families: muon, electron and tau neutrinos) and differences between neutrinos and anti-neutrinos, which could shed some light on the CP violation, a fundamental law which could explain why more matter than antimatter exists in the universe.
Ice cover in arctic seas reaches new low: a satellite survey by NASA reported that ice cover in the arctic seas reached a new low on August 2012, taken from a sample of recordings since 1979. It is also expected to be lower on September. Scientists at NASA say the increased sea ice lost is due to the increased temperatures last year. The survey recorded a surface of 1.58 million square miles, from 1.61 million square miles in September 2007. Professor Peter Wadhams, from Cambridge University, reported to BBC News that models and calculations show that the arctic sea could become ice-free by 2015 or 2016. The alarmist view of the professor has been criticized in the past, but this new measurement could show hints toward this prediction. The ice cover getting thinner is a positive feedback system - which accelerates when it starts - as warmer temperatures caused by less ice in the seas allows the generation of storms which destroys more ice and accelerate its melt. The implications of ice-free artic seas are serious, as lack of ice would decrease the reflected light by the planet increasing temperatures even further, and causing permafrost to melt, which would release copious amounts of methane, a powerful greenhouse gas.
NASA plans new mars mission: just after a few weeks from the launch of Curiosity, the new mars rover, NASA announces plans a 425 million dollars lander which scope would be drilling into the red planet to probe its mantle, crust and core. The analysis of the interior of Mars would help understand how it evolved from the stage of incandescent ball of magma. Earth's interiors have been unveiled analyzing seismic activity, but the structure of the other rocky planets (Venus, Mars and Mercury) is mostly unknown. Mars is big enough to have developed a crust, mantle and core, but does not show the expected tectonic activity.
