NASA will attempt a 'risky' manoeuvre to fix Hubble telescope TODAY

NASA has announced that it will attempt a'risky' manoeuvre to fix its 31-year-old Hubble space telescope later today. Hubble accidentally went offline due to a mysterious glitch on June 13 that took down one of its main computers. But NASA says it's located the source of the problem – a faulty power regulator in the computer's Power Control Unit (PCU). It will attempt a switch to a backup PCU staring Thursday (July 15), which, if successful, will bring Hubble back to normal science operations in'several days'. Hubble, a joint project of NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA), has been observing the universe for over three decades.
