NASA’s space agency says the Hubble telescope may switch to backup devices later this week. It may mean that the space telescope can resume its scientific research. The problem started a month ago.
NASA says In a brief update, it has completed a formal investigation into all operations related to a possible switch to backup devices. That switch is likely to happen later this week, although a reason is being investigated crashed payload computer It’s still going.
It remains to be seen if the supposed enablement of backup devices will work by the end of this week. A month ago, NASA tried to switch to two spare memory modules, but failed. The command to enable the backup module could not be completed. Subsequent efforts, including the collection of diagnostic information, were also unsuccessful.
NASA previously suspected the memory module to be the cause, but the organization indicated that the memory errors might also just be a symptom and that another piece of hardware could be the cause. The drive unit/data science coordinator and the power control unit were also later considered in the power control unit. If one of these systems is the suspected cause, it will be difficult to switch to backup devices. If using the Standby Command Module/Scientific Data Coordinator or the Standby Power Controller, multiple hardware parts of the spacecraft must also be swapped due to the way they are connected to the science instrument command and data processing. The payload computer is part of that.
The task of a useful computer is to manage and control all scientific instruments. A month ago, this computer no longer received the “Stay Alive” signal; This is the normshake hand Between the payload computer and the main telescopes to indicate that everything is fine. When this signal was not met, all scientific instruments were automatically put into safe mode. This is still the case, which means that no scientific research was possible a month ago.
