Ariane 44LP | Astra 1B & Meteosat 5

Astra 1B was the second of the Astra communications satellites launched and operated by SES (Société Européenne des Satellites). It was believed to have been launched in a faulty condition, and suffered a thruster failure early in its life, causing minor drift, meaning that it became permanently difficult to obtain a steady lock on the satellite. This was most notable on analogue transmissions where the picture would move from clear to carrying sparklies and back again.
