Do the ASTRA satellites ever go wrong?

Answer

The ASTRA satellites are immensely complex and, like all machinery, can develop a fault or even fail and in orbit, they cannot be repaired. The satellites also have a limited life and are not expected to operate to their full capacity for ever. However, we launch replacement satellites before those in orbit reach the end of their useful life. We also closely monitor the performance of all the satellites 24/7 and operate a policy of in-orbit backup so, in the event of a problem, another satellite in the same orbital position can be brought in to take over the broadcasts.
