These are the first global color maps of these moons produced from the Cassini data. he most obvious feature on the maps is the difference in color and brightness between the two hemispheres. The darker colors on the trailing hemispheres are thought to be due to alteration by magnetospheric particles and radiation striking those surfaces. The lighter-colored leading hemisphere is coated with icy dust from Saturn's E-ring, formed from tiny particles ejected from Enceladus' south pole. These satellites are all being painted by material erupted by neighboring Enceladus. The colors shown in these global mosaics are enhanced, or broader, relative to human vision, extending into the ultraviolet and infrared range. Resolution on Tethys in the maps is 250 meters per pixel. Image selection, radiometric calibration, geographic registration and photometric correction, as well as mosaic selection and assembly were performed by Paul Schenk at the Lunar and Planetary Institute. Original image planning and targeting for Saturn's icy moons were performed by Tilman Denk (Frei Universitat, Berlin) and Paul Helfenstein (Cornell University, Ithaca, New York). The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo. obs_ack = NASA/JPL-Caltech/Space Science Institute/Lunar and Planetary Institute prov_progenitor = JPL/PhotoJournal prov_progenitor_url = https://photojournal.jpl.nasa.gov/catalog/PIA18439 #bib_reference = Bibcode for bibliographic reference #bib_reference_url = URL to bibliographic reference #obs_copyright = Copyright mention of the original data #obs_copyright_url = URL to copyright page of the original data #t_min = Start time in MJD ( =(Unixtime/86400)+40587 or https://heasarc.gsfc.nasa.gov/cgi-bin/Tools/xTime/xTime.pl) #t_max = Stop time in MJD #obs_regime = Waveband keyword (Radio Infrared Optical UV X-ray Gamma-ray) #em_min = Start in spectral coordinates in meters ( =2.998E8/freq in Hz, or =1.2398841929E-12*energy in MeV ) #em_max = Stop in spectral coordinates in meters hips_builder = Aladin/HipsGen v10.125 hips_version = 1.4 hips_release_date = 2019-05-21T07:08Z hips_frame = tethys hips_body = tethys hips_order = 3 hips_tile_width = 512 #hips_service_url = ex: http://yourHipsServer/Tethys Cassini-PIA18439 hips_status = public master clonableOnce hips_tile_format = jpeg hips_pixel_scale = 0.01431 s_pixel_scale = 0.02673 dataproduct_type = image moc_sky_fraction = 1 hips_estsize = 18357 hipsgen_date = 2018-01-24T13:30Z hipsgen_params = "hhh=Tethys/Tethys.jpg 13467x6734" partitioning=6734 -maxthread=10 in=Tethys creator_did=CDS/P/Tethys/Cassini-PIA18439 -f color=jpg INDEX TILES hips_creation_date = 2018-01-24T13:30Z hips_order_min = 0 dataproduct_subtype = color hipsgen_date_1 = 2019-05-21T07:08Z hipsgen_params_1 = out=/asd-volumes/sc1-asd-volume6/Planets/CDS_P_Tethys_Cassini-PIA18439 UPDATE
