MODIS/Aqua 24-hour Spacecraft ephemeris/orbit data files to be read via SDP Toolkit Binary Format - NRT
PM1EPHND is the Aqua Near Real Time (NRT) daily spacecraft definitive ephemeris data file in native format. This is MODIS Ancillary Data. The data collection consists of PM1 Platform Attitude Data that has been preprocessed by ECS to an internal standard supported by the ECS SDP Toolkit. This data is typically used in determining the geolocation of earth remote sensing observations.The file name format is the following:PM1EPHND_NRT.Ayyyyddd.hhmm.vvv where from left to right:PM1 = PM1 (Aqua);EPH = Spacecraft Ephemeris; N = Native format; D = Definitive; A = Acquisition; yyyy = data year, ddd = Julian data day, hh = data hour, mm = data minute; vvv = Version ID.

MESSENGER MDIS CALIBRATED DATA RECORD V1.0
공공데이터포털
Abstract ======== The Mercury Dual Imaging System (MDIS) consists of two cameras, a Wide Angle Camera (WAC) and a Narrow Angle Camera (NAC), mounted on a common pivot platform. This dataset includes the Calibrated Data Record (CDR) version of valid images than can be turned into physical units, that were acquired during the cruise phase to Mercury, and includes post- launch checkout images, flyby images of Earth, Venus, Mercury, images acquired from Mercury orbit, and inflight calibration images. This CDR dataset is the product of conversion of raw data (Experiment Data Records, or EDRs) to one of three options: physical units of radiance; or radiance factor or I/F, with or without an empirical correction for time variable instrument responsivity. In addition to the imagery, anciliary information (including calibration files used to calibrate the data) is included.
GALILEO JUPITER PLASMA RAW PACKETIZED TELEMETRY V1.0
공공데이터포털
This data set contains instrument packet files (IPFs) from the Plasma Science experiment (PLS) onboard the Galileo spacecraft during the Jupiter orbital operations phase. This data set is a very raw, binary form. It is archived for completeness only. There is another PDS data set (GO-J-PLS-3-RDR-FULLRES-V1.0) that contains all of the plasma detector counts in a form that is much easier to work with. The primary advantage of this data set is that it contains instrument housekeeping and engineering data in addition to the counts.
EPOXI HRII/HRIV/MRI INSTRUMENT TEMPERATURES V3.0
공공데이터포털
This dataset contains the raw and smoothed (averaged) instrument thermal telemetry for the entire EPOXI mission from 04 October 2007 to 08 August 2013. Measurements were collected by 59 thermal sensors located in the HRII, HRIV, and MRI instruments, on the instrument platform, and on the solar wings of the Deep Impact flyby spacecraft. For Version 3.0, thermal data from 06 February 2011 to 08 August 2013 were added.
EPOXI EARTH OBS - HRIV CALIBRATED IMAGES V1.0
공공데이터포털
This data set set contains version 1.0 of calibrated narrow band filter images (350-950 nm) of Earth acquired by the Deep Impact High Resolution Visible CCD 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. HRIV images were acquired once per hour with the filters centered on 350, 750 and 950 nm, whereas the 450-, 550-, 650-, and 850-nm data were taken every 15 minutes. 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.

EPOXI EARTH OBS - HRII CALIBRATED SPECTRA V1.0
공공데이터포털
This data set set contains version 1.0 of calibrated, 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.
