Two and a half years after launch, on 25 June 1998, the mission almost ended during a routine spacecraft maneuver. Contact was lost and some wrote off SOHO as lost for good. However, the team refused to surrender, and after painstaking work over a three-month period, they managed to bring the mission back online by the end of September.
> Following a period of re-commissioning the spacecraft and its twelve instruments - all of which survived despite the extreme temperatures they suffered during the blackout - the mission was fully back online in early November. But the troubles were not over yet. By the end of the next month, all three of the spacecraft's gyroscopes had failed, igniting a new race against time to save the mission. New software was developed that could control SOHO without the need of gyroscopes. Installed in February 1999, the code allowed the spacecraft to return once more to full scientific operations. In the process, this made SOHO the first spacecraft to be stabilized in three axes without gyroscopes.
