SUMMARY: Scientists at the University of Chicago have received their first samples of cometary dust from NASA's Stardust mission, which returned back to Earth in mid-January. The samples consist of several thin slices of a single dust grain, as well as a larger piece which can be sliced up even finer. Mission scientists believe that the spacecraft collected a total of 2,300 particles larger than 15 micrometres across (1/3rd the width of a human hair).

I don't know whether to hope that the samples are not different in any substantial way from some already plentiful class of meteorite material (making studies easier), or for it to show some remarkable new property, making this stuff more interesting. Either way, the result will be exciting.

I have read two accounts about the data, one from Texas that said the results are exactly as predicted, and one from England saying that they are absolutely astonished at what they are looking at.

A happy medium would be nice.

Any particles which have traces of elements more complex than olivine or radio-active isotopes will increase the likelihood of another mission.
