Hey, you’ve gotta hand it to the folks at NASA, who used a time-honored trick to get the 28-year-old Hubble Space Telescope back in operation. Earlier in October, a gyroscope used to point HST at observing targets failed and a backup didn’t start up properly. The fix? Basically turning various systems on and off as well as making some maneuvers. Think of this as the spacecraft equivalent of rebooting your computer or whacking it on the side…

Hubble returned to normal operations on Saturday; it’s currently doing a long-exposure observation of a star-forming galaxy in the infrared spectrum. The orbiting observatory has made over 1.3 million observations since it was launched.
