Happy 30th Birthday, Pioneer 10

Posted by timothy on from the not-yet-over-the-hill dept.

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."

  1. talk about clear reception.. by supernova87a · · Score: 5, Interesting

    The amazing thing is that the satellite is sending out a signal with as much power as maybe a watch battery, and we're receiving it from over 10^9 km away...

    Of course, the receiving dish is as big as a football field, but still.

  2. The reverse may apply, too by Rob+Cebollero · · Score: 5, Interesting

    Imagine if one day we *do* see an extraterrestrial probe land here. As far advanced as it will appear to us, it may only be an ancient relic of its creating civilisation.
