Two NASA telescopes orbiting Earth shut down within a week
Less than a week after the Hubble Space Telescope went offline, the Chandra X-ray Observatory automatically went into safe mode on Wednesday possibly due to a gyroscopic failure, said NASA. Hubble went into hibernation last Friday also due to a misalignment issue. "Chandra decided that if Hubble could have a little vacation, it wanted one too," said a Chandra astronomer.
