"Exosphere" in this context seems like a pretty broad application of the term, though. Any solid body is going to emit a certain amount of gas in a vacuum, however exceedingly small that might be.
It's a smart & interesting experiment nevertheless. There appears to be a continuum of possible volatile content levels for members of the Belt's general asteroid population as well as an increasing number of objects that seem to be intermediate between the traditional categories of "comet" & "asteroid". Measuring the emissions of Luetia will provide some very valuable baseline data that directly pertains to all that. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
