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?

speaking of which, radio hams wanting to try to receive the carrier from the probe can find infos on the communication system here and here (scroll to the section on ICE).
orbital data are much more difficult to find and ICE is not on JPL's Horizon. There are daily heliocentric ephemeris up to 1997 here and lots of old orbital data here. Unfortunately, the latter date from before the sizeable 1986 maneuvers (see this pdf for info), So they are probably useless, even if you had a good orbit propagator to take into account all perturbations (including solar radiation pressure that must be non negligeable for such a small spacecraft). |
