What's the latest on this craft? I've not seen anything for a long time.

The last very weak signal was received on January 23 2003.  NASA made another attempt at contact in early February of 2003 but no reply was received.  It is thought that the power from the RTG is now too low to power the radio transmitter so no more attempts at contact were made.

This is one of the last things I've got on the spacecraft:

This little probe has been one of the most amazing thing man has ever made... I was grown up with here and I was so deeply sad when they shutted down the mission in early 2003...

Btw, how many interstellar probes are out there in deep space? Btw, I think only the voyager twins are still alive, right?

Pioneer 10 and 11, Voyager 1 and 2, and now New Horizons are the only probes on escape trajectories.

The diagram above refers to the 'Pioneer Anomoly,' as it is known, which scientists have been unable to explain yet. Some extremist physicists believe it may alter the entire theory of the Universe pioneered (pun intended) by Einstein.

btw, i didn't think New Horizons was on an escape trajectory... isn't it going to orbit Pluto visit Charon?

No, it was going to do a Pluto/Charon flyby and then do a flyby of another KBO. So, Ben is right, it's on an escape trajectory. :)

No, it is not was. Hasn't launched yet.

:-)

Pioneer 10 and 11 both went silent when, as stated, the nuclear decay rate dropped below the amount needed to send out a powerful enough signal for us to detect. If we had a larger dish than the DSN, we might still be hearing from it.

Haha, you are just as guilty, Ben. We both are having some trouble with our tenses today!
