The problem isn't only the half life of the plutonioum, its the degredation of the rest of the RTG scintillators.

I imagine that the antenna pointing accuracy must be incredibly precise.

Noted. It'd be tough to send a repair guy out there to PM it as well ...

Thanks R.A.
(((ping))))

Wow, you guys are so smart. I wasn't even aware we had a craft this far out. I better broaden my horizons a bit . . .

Some mileage bonus :)
To: Joe Hadenuf
They are getting pretty good :)
To: RadioAstronomer
The mileage bonus is all yours ... I want the overtime check ;)

Scientists beamed a message to the craft Friday from a radio telescope in the desert east of Los Angeles. A radio telescope in Spain received the response 22 hours and six minutes later, said Larry Lasher, the mission's project manager.I believe radio signals travel just below the speed of light, so would this mean it took about 11 hours 3 minutes each way? Was the signal transmitted as soon at it was received from the spacecraft or was their processing time involved?

I believe radio signals travel just below the speed of light,Radio wave ARE light. Just at a lower frequency than our eyes can detect.

This evening is one reason I got NASA TV on my dish ... the video from the capture of Hubble today was fantastic. They're about to start disassembling the old solar panels on Hubble and installing the new, rigid ones.

Was the signal transmitted as soon at it was received from the spacecraft or was their processing time involved?Depends on the command. Some (if not most) spacecraft have an echo return of the commands sent so the ground can determine if the proper commands were recieved by the spacecraft.
To: RadioAstronomer
So radio signals travel at the same speed as light waves?
To: RightWhale
KEWL!!!!
To: Joe Hadenuf
In a vacuum, yes. The velocity changes with frequency (very small) in other mediums such as an atmosphere or water.
