On July 30-31, the spacecraft conducted another Sample Mass Measurement (SMM) calibration activity. After sample collection, the mission team will use the SMM pirouette to measure the mass of the collected regolith in the TAGSAM head. The team is awaiting the downlink of the complete data set from the spacecraft to be able to analyze the performance of the spin maneuvers, but preliminary data indicates that they executed as expected.
