14 CFR 1203.404: Handling of unprocessed data.

It is the usual practice to withhold the release of raw scientific data received from spacecraft until it can be calibrated, correlated and properly interpreted by the experimenter under the monitorship of the cognizant NASA office. During this process, the data are withheld through administrative measures, and it is not necessary to resort to security classification to prevent premature release. However, if at any time during the processing of raw data it becomes apparent that the results require protection under the criteria set forth in this subpart D, it is the responsibility of the cognizant NASA office to obtain the appropriate security classification.
