    • EPOXI EARTH OBS - MRI CALIBRATED IMAGES V2.0

    Metadata Updated: August 22, 2025

    This dataset contains calibrated, 750-nm filter images of Earth acquired by the Deep Impact Medium Resolution Visible CCD (MRI) during the EPOCh and Cruise 2 phases of the EPOXI mission. The MRI instrument was only used during the first Earth observing period on 18-19 March 2008 and the last two on 27-28 March and 04-05 October 2009. Each observing period lasted approximately 24 hours, and one MRI image was taken simultaneously with the first north/south scan of the HRI IR spectrometer at half-hour intervals to serve as context spectra. On 27-28 September 2009 during the first attempt at Earth south polar observations, a full set of MRI context images was acquired although the HRII and HRIV instruments were turned off by fault protection shortly after the sequence started. Version 2.0 includes the application of a horizontal destriping process, new absolute calibration constants for filters, and revised electronic crosstalk calibration files.
