NASA is taking additional steps to investigate the malfunction that happened to the computer of the space telescope 'Hubble' that began on June 13 and caused the suspension of scientific observations. At the same time as the investigation, NASA is looking at indirect ways to activate the backup hardware integrated in the satellite. The telescope itself and the rest of the scientific instruments were not damaged, and they were moved to a safe state.
The source of the problem is in the unit that contains the information and data handling (SI C & DH), where the load computer is also located. Some bits of hardware on SI C & DH may be the source of the malfunction.
The team is currently testing the control unit of the scientific data system - a component that sends and decodes commands and data. They also examine the power unit's regulator inside the power control unit, which is designed to ensure a stable supply of voltage to the computer's hardware. If the person responsible for the malfunction is found in one of these systems, the team must complete a complicated series of operations in order to switch to the backup units. This procedure will be more complex and dangerous than the ones the team tried last week - so switch to hardware backup systems and memory components. To switch to a backup CU / SDF or power regulator, there are also other hardware boxes on the spacecraft that need to be enabled due to the way the SI C & DH unit is wired.
Over the next week, the group will review and update all operating procedures, commands, and related items needed to activate the switch to the backup hardware. They will then test their performance against a high-fidelity simulator.
The team activated a similar switch in 2008, which allowed Hubble to continue science operations as normal after the Cu/SDF module failed. On Hubble's last service mission in 2009, the entire SI C & DH unit, including the faulty Cu / SDF module, was replaced with the unit currently in use.
Since then 'Hubble' has made about 600,000 additional observations which bring the total number of observations made during its thirty years of life to more than 1.5 million. These observations continue to improve our understanding of the universe.
The telescope was launched in 1990 and has been observing the universe for 31 years. He contributed to some of the most significant discoveries about our universe, including the acceleration of the universe, the evolution of galaxies over time, and the first atmospheric studies of planets beyond our solar system.

Not suitable for 'Hidan', which usually provides quality content.
This highlights how important it is to launch James Webb
If the space telescope was in working order, he would surely have seen that the search had begun for a brave mathematician who would agree to admit "that what is known as the mathematical constant pi" is not constant at all, but varies between 3.1416 and 3.164
