NASA's 28-yr-old Hubble telescope active again after 22 days
NASA's 28-year-old Hubble Space Telescope has resumed its operations after 22 days, the agency said on Saturday. The telescope had suffered a backup gyroscope malfunction on October 5 which caused it to show the rate of rotation far in excess of the actual rates. NASA was able to stablilise and realign Hubble by switching it between different operational modes.
