EPOXI EARTH OBS - HRII RAW SPECTRA V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: July 17, 2025 | Last Modified: 2025-07-17

This data set set contains version 1.0 of raw, 1.05- to 4.8-micron spectra of Earth acquired by the High Resolution Infrared Spectrometer (HRII) during the EPOCh phase of the EPOXI mission. Three sets of observations were acquired on 18-19 March, 28-29 May, and 4-5 June 2008 to characterize Earth as an analog for extrasolar planets. Each observing period lasted approximately 24 hours, and spectra were acquired twice per hour. During the observing period in May, the Moon transited across Earth as seen from the spacecraft. Additional Earth observations are planned for the mission, and these data will be added to a future version of this data set.
