Happy 30th Birthday, Pioneer 10

tlon writes: "Pioneer 10, the spacecraft that brought us the first pictures of Jupiter, turned 30 today. Launched in 1972, the probe is now some 7.4 billion miles away, as it cruises out towards Aldebaran, the eye of Taurus. NASA will attempt to contact the spacecraft today, (it was successfully contacted last year), but the round trip time is over 22 hours. How's that for a ping latency? See Nasa's Pioneer 10 Page for more details."
