This product represents averaged radiometric diameters and geometric albedos derived from observations made by the Infrared Astronomical Satellite in 1983 for 1796 numbered asteroids and 88 unnumbered asteroids whose orbital elements were determined using astrometry from two or more apparitions.
SPICE deals with ancillary data needed to support the planning for, and analysis of, science instrument data. As well as software (the SPICE toolkit) and documentation, SPICE provides data files, called kernels, that contain ancillary information which has been created in such a way as to allow easy access and correct usage by the space science and engineering communities.
The High Rate Detector (HRD) from the University of Chicago is an independent part of the CDA instrument on the Cassini Orbiter that measures the dust flux and particle mass distribution of dust particles hitting the HRD detectors. This data set includes all data from the HRD through June 30, 2010. Please refer to Srama et al. (2004) for a detailed HRD description.
This archive contains digital elevation models (DEMs) of the lunar south pole. Elevation data at 200 pixels per degree of latitude (~150 m spatial resolution) were obtained with radar interferometry from the Goldstone Solar System Radar and calibrated with Lunar Reconnaissance Orbiter laser altimetry data. Elevations are given in meters with respect to a 1737.4 km sphere.
The Cassini Radio Science Titan Gravity Science Experiment (TIGR16) Raw Data Archive is a time-ordered collection of radio science raw data acquired on February 17, 18 and 19, 2011, during he Cassini Extended-Extended Mission.
Dust Impact Detection System (DIDSY) consists of six independent subsystems with the primary aim of registering the impacts of all particulates of significant mass incident on the probe during the post-perihelion encounter with Comet Halley in 1986. Mounted on Giotto's front dust shield, the detectors will determine the mass spectrum of the dust, with a limiting sensitivity of some 10^^-17^^ g, increasing to the largest grain masses encountered along Giotto's trajectory through the cometary environment with an ultimate spatial resolution of some 70 km. An additional detector is located on the rear shield to monitor those dust particles (m > ~ 5 X 10^^-7^^ g) that are able to penetrate the front dust shield. An ambient plasma monitor is also incorporated into DIDSY to measure the inJpact plasma generated by both dust and gas impacts on the spacecraft. The system is controlled and its data processed by a microprocessor-based system that allows the wide range of anticipated impact rates (varying from a few per minute, to ~ 10^6 s^^-1^^ at closest approach) to be handled. The instrument weighs 2.26 kg and consumes 1.9 W of power during normal operation.
This data set contains Calibrated data taken by the New Horizons Linear Etalon Imaging Spectral Array instrument during the Jupiter encounter mission phase.
This data set contains CODMAC level 3 data acquired by the Rosetta Orbiter ALICE UV Spectrometer during the third earth flyby mission phase, which took place between 2009-09-14 and 2009-12-13.
The Cassini Radio Science Saturn Ring and Atmospheric Occultation experiments (SROC17) Raw Data Archive is a time-ordered collection of radio science raw data acquired on November 10, 2012, during the Cassini Extended Extended Mission.
