NASA's status report for STS-93 today stated the following:

>Collins and Ashby also continued to provide investigators with data for a
pair of experiments
>involving the study of exhaust vapors from the engines of space vehicles by
firing reaction
>control system and orbital maneuvering system engines several times as
Columbia passed over
>worldwide tracking network stations.

Can anyone point me to a more complete description of this experiment?

Thanks,
