Switch to a backup system is successful
NASA engineers late on October 15 successfully rebooted the Hubble Space Telescope, which has been silent since September 27, when a unit that formats data so it can be relayed to Earth suddenly failed.
Engineers were able to switch Hubble from the failed unit to a duplicate device, officially known as the science instrument control and data handling system, which is still operating on the 18-year-old spacecraft.
