Maybe someone who knows satellites can help here. I assume with one gyro the satellite still has pointing function because one gyro senses in 3 axis, but that if that one gyro were to go it would no longer know where it was pointing or perhaps without enough accuracy for science.
But... it’s a telescope. Couldn’t it determine direction from images received from a spotting or wide angle lens? Does it not have one?
