    Hubble is fully operational once again

    In the history of space exploration, a handful of missions have set new records for ruggedness and longevity. On Mars, the undisputed champion is the Opportunity rover, which was slated to run for 90 days but remained in operation for 15 years instead. In orbit around Mars, the honor goes to the 2001 Mars Odyssey, which is still operational 20 years after it arrived around the Red Planet.

    In deep space, the title for the longest-running mission goes to the Voyager 1 probe, which has spent the past 44 years exploring the Solar System and what lies beyond. But in Earth orbit, the longevity prize goes to the Hubble Space Telescope (HST), which is once again fully operational after experiencing technical issues. With this latest restoration of operations, Hubble is well on its way to completing 32 years of service.

    The issue began at 01:46 A.M. EDT (10:46 P.M. PDT) on October 23rd, when NASA reported that the venerated space telescope was sending error codes, which indicate the loss of a specific synchronization message. This message provides timing information that Hubble's instruments use to respond to data requests and commands correctly. The same error codes were issued two days later, indicating multiple losses of synchronization messages and triggering Hubble to enter safe mode.

    Throughout November, NASA's Hubble team attempted to restart its main computer and backup systems. On November 8th, they announced that they had retained partial control by bringing the telescope's Advanced Camera for Surveys (ACS) back online. They followed by restoring the Cosmic Origins Spectrograph (COS) and the Wide Field Camera 3 (WFC-3), Hubble's most heavily-used instrument.
