How Failed Gyros Are Making Hubble's Life Harder

After decades of operation on orbit, the Hubble Space Telescope is now missing critical hardware which was required in its original design. Three Gyroscopes are supposed to be needed, so the telescope launched with 6, but they keep failing and now there are only two.
However, engineers have come up with new control algorithms to allow operation with fewer gyroscopes, and this is what I want to explain.
