NASA's Hubble Telescope experiences mechanical failure

The Hubble Space Telescope experienced a malfunction when two of its four operational gyroscopes stopped working. NASA reported that the telescope had been functioning with four out of its six gyroscopes. After one gyroscope failed, controllers attempted to switch to a newer one, which also failed, leaving Hubble with only two fully operational gyroscopes. These gyroscopes are crucial for steering the telescope and ensuring its stability in space.

What is the primary function of the gyroscopes on the Hubble?

According to reports, how many fully functioning gyroscopes does the Hubble have left?
