The computer coordinates and controls the various telescope instruments and also monitors them for technical issues.
The US space agency successfully completed a procedural test this week, which is essential for switching to Hubble’s backup hardware. It was a payload computer for the telescope Manufactured in the 80’s It is responsible for controlling and monitoring all of the Hubble science instruments.
This computer, which is necessary to continue Hubble’s scientific operations, suddenly stopped working on June 13, Commenting on scientific notes telescope.
the source of the problem
At the moment, it is unknown What is the reason for failure?, although it has been determined that the source of the problem is in piece of “hardware” The Scientific Instruments and Data Management Controller (SI C&DH) unit, which coordinates commands and data and sends them to scientific instruments.
To solve the problem, the engineers made the decision Switch to Backup Devices. In such cases, the Hubble payload computer has secondary spare ‘hardware’, although a change has been made. It’s not easy, because it requires turning off the other parts.
