This information from Emily is amazing.

ICE is alive and may perhaps be assigned to a new mission.

An ignorant question here, but why would you instruct a still-functioning spacecraft to turn off it's radio transmitter? Wouldn't that almost guarantee to kill the spacecraft (or at least make it harder to find?)

I can't imagine the radio output would be powerful enough to interfere with any radio studies (and long-term tracking info might be kinda fun anyway - to measure all those funky solar pressure effects and so on....)

That's sort of the point

Yes, but what's the harm in leaving the spacecraft alive? If you neglect possible radio interference with a DSN station while it's trying to communicate with another s/c on the same frequency and in the same part of the sky, but really, what are the odds of that happening?

[Hungry4info]

Yes, but what's the harm in leaving the spacecraft alive?

Funding.

[ugordan]

Funding.

Funding doesn't run the spacecraft radio transmitter. It does not do so whether we're listening or not.

[Hungry4info]

Oh. I thought one needed to continue funding a mission for it to remain active/operational, like with Voyager. Is the funding to pay the people who work with the spacecraft?

Polluting the solar system with radio waves could be a serious issue as we develop more sensitive instruments for listening to the cosmos.

I don't see how this can worsen the situation when we've already crowded the Earth orbit with all kinds of radio-active stuff. As along as it's tracked and catalogued, no confusion should arise. We might as well turn the Voyagers off then - or do missions that radiate, but continue to be funded not classify as "pollution"?
