Whisper Heard From Pioneer 10

Irishman writes "NASA has heard from the Pioneer 10 spacecraft for the first time since March. Unfortunately, it is too faint to get scientific data from the craft. CNN has the story here. Considering that the craft is twice the distance from the Sun as Pluto is and that it has spent 30 years subjected to space, this is amazing! Now if only computer manufacturers could make equipment even remotely this sturdy."

      Yeah, I know that I was being pendantic. I think its just a difference in perspective between physicists and chemists/geologists.

      By the way, if you had said natural abundance, then I wouldn't have had a problem with it. Plutonium is not found in measurable amounts in nature on Earth. Plutonium isotopes do occur in nature on Earth, just not in measureable quantities. Every nuclear reaction that occurs in a nuclear reactor also occurs in nature on Earth (due to background raditaon hitting uranium, etc.), but just not very often.

    Besides having a large dish on earth do communication is one thing... and having communications system based on a remote probe is another.
    Moreover the Voyager serves the purpose too. It is farther than Pioneer... infact it is the farthest man made object. It is working perfectly right now. Rather than send repeaters after the sent out probes what is preffered is to send better probes in another direction.

  4. Where is it going? by phorm · · Score: 4, Insightful

    Where exactly is the Pioneer headed to. Is it intended to eventually make a circular path and eventually head home, or will it just continue to wander out into space? If we could start planting satellites in circular synchronous orbits, perhaps we could eventually have a transmission array that could gradually extend throughout the solar system.

    Sending out probes is cool when we can collect info, but it's not really useful if the data isn't able to be processed. A probe that wanders away isn't really very useful, unless perhaps somebody picks it up and sends it home or comes to visit.
