Any weblinks where we can learn something about the where-abouts of ICE/ISEE ( International Comet Explorer / International Sun Earth Explorer ) as the craft was expected to return to Earth in 2014?

Is receiving telemetry the same as getting transponding?

Is receiving telemetry the same as getting transponding? No; transponding is just getting a phase-coherent copy of the uplink carrier back on the downlink without modulation. But based on the last updates to http://spacecollege.org/isee3/ they have succeeded in commanding the s/c to send modulated data. Still not clear what if anything is being sent, but this is definitely very encouraging. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
