NASA – NASA is ending attempts to regain contact with the long-lived Mars Exploration Rover Spirit, which last communicated on March 22, 2010.
A transmission that will end on Wednesday, May 25, will be the last in a series of attempts. Extensive communications activities during the past 10 months also have explored the possibility that Spirit might reawaken as the solar energy available to it increased after a stressful Martian winter without much sunlight. With inadequate energy to run its survival heaters, the rover likely experienced colder internal temperatures last year than in any of its prior six years on Mars. Many critical components and connections would have been susceptible to damage from the cold.
Engineers’ assessments in recent months have shown a very low probability for recovering communications with Spirit. Communications assets that have been used by the Spirit mission in the past, including NASA’s Deep Space Network of antennas on Earth, plus two NASA Mars orbiters that can relay communications, now are needed to prepare for NASA’s Mars Science Laboratory mission. MSL is scheduled to launch later this year.
Spirit landed on Mars on Jan. 3, 2004, for a mission designed to last three months. After accomplishing its prime-mission goals, Spirit worked to accomplish additional objectives. Its twin, Opportunity, continues active exploration of Mars.
Lengthy detective work with data NASA’s Mars Exploration Rover Spirit collected in late 2005 has confirmed that an outcrop called “Comanche” contains a mineral indicating that a past environment was wet and non-acidic, possibly favorable to life. more> http://is.gd/MeA01V

By John Moe – The House Subcommittee on National Security, Homeland Defense and Foreign Operations is examining issues related to cybersecurity in a hearing scheduled for Wednesday. Republicans hold a majority in the House. They have indicated that while they may not be as eager to sign off on President Obama’s cybersecurity plans as their colleagues in the Democrat-led Senate, they would like to get something done to protect our Internet infrastructure against escalating attacks.
EurActiv – Most business leaders believe that Europe’s young people lack the so-called ‘soft skills’ that are considered essential by many employers. Closer links between business and schools are seen as a way to bridge this skills gap.
