Anyone know whether and how this question has been conclusively answered?

Extract from interview with Jacob Trombka, team leader for NEAR Shoemaker's
gamma-ray spectrometer instrument:

        "One curious find from the probe's magnetometer is that no remnant
magnetism has been found on Eros. Yet the gamma-ray data does show an iron
signal, which means that Eros is loaded with a demagnetized iron of some
sort.

           Those two factors are causing us to scratch our head, to try and
figure out what's going on here," Trombka said. "Eros is a very primitive
body. The question is whether this is a primitive body that we haven't seen
here on Earth in terms of meteorites collected to date." "

Seems appropriate that this question should arise from the spacecraft named
after Eugene Shoemaker.

sorrowfully, we stand by you
