While a week has passed since the Hubble Space Telescope went into safe mode for the third time, this important scientific tool has not yet been able to return to normal.
According to NASA, the problem began in the early hours of October 23 when error codes generated by Hubble Science Tools referred to "the loss of a specific sync message." These messages allow tools to accurately respond to data requests and commands. Following this error, the team members performed the required correction mission on the Hubble system and allowed the scientific operation to resume the next morning. 38 In the morning of the Eastern time zone (10:08 Tehran time) the same thing happened again, but this time the scientific tools lost a set of synchronization messages instead of a message. As a result, Hubble automatically went into safe mode and has been in this state ever since. Hubble scientific operations have now been halted, but the NASA team insists that Hubble's instruments are "safe" and that the space telescope will remain in Safe Mode for the duration of the investigation.
Launched in 1990, it has provided stunning views of the universe and valuable astronomical data. Hubble The joint mission of NASA and the European Space Agency was supposed to last only 15 years, but despite occasional flaws, it is still active, and according to current Hubble signs, by the end of the 2020s and possibly even the 2030s. It will continue to operate.
Mission specialists are currently working to better analyze the current situation regarding the synchronization problem by analyzing the spacecraft data and system diagrams. They are also working on developing new methods of collecting data from Hubble, a process that is expected to take at least a week, but no timeline has yet been set for Hubble to return to regular scientific operations.
This is the third This is the time when Hubble will enter safe mode in 2021, and one can only hope that this time too the telescope will wake up safely. The situation on June 13 this year, when Hubble entered safe mode due to a malfunction of the power control unit, seemed vague, and it took a full month for NASA to return Hubble to the conductor state, which was eventually converted to successful backup hardware. . Hubble also went into safe mode last March due to a software flaw. An event that also took place in 2008, 2018 and 2019.
Despite these problems, Hubble is an extraordinary scientific tool and it is hoped that it will return to normal as soon as possible. Its successor, the James Webb Space Telescope, is also preparing for launch in late fall. The launch is currently scheduled for December 18.
