  1. This bundle consists of Passive Seismic Experiment (PSE) observations in two collections, the SEED (Standard for the Exchange of Earthquake Data) collection and the ASCII table collection. The SEED collection contains data in MiniSEED files and their metadata in DatalessSEED files. The ASCII Table collection contains the same data in PDS-compliant ASCII files, with the data in GeoCSV (comma-separated value) tables and the metadata in StationXML files. These data were compiled by Ceri Nunn, Yosio Nakamura, Sharon Kedar, and Mark Panning as part of a PDART project and archived by the PDS Geosciences Node.

  2. The Ronald Greeley 35mm Slide Collection consists of color and grayscale slides that include images of planetary bodies (Moon, planets, asteroids, and comets), planetary missions (e.g., Voyager, Galileo, Viking), planetary analog sites on Earth, and presentation materials for research results presented at national conferences. The slides were produced by Dr. Ronald Greeley during his tenure as a research scientist in the late 1960s while at working at NASA Ames, through to the early 2000s when he was a Regents Professor at Arizona State University. The slides were digitized to preserve the research materials of Dr. Ronald Greeley, who played a critical role in the planetary missions to the planets of the inner and outer Solar System.

    Presently, only the Jovian System bundle is archived at the Geosciences Node. Additional bundles may be added in the future.

  3. The MSL Mastcam Photometry bundle is released.

    This bundle contains derived data from the Mastcam and Navcam instruments on the Mars Science Laboratory Curiosity rover. The three-dimensional cubes contain core bands of Mastcam multispectral images calibrated to radiance and radiance factor. Navcam stereo images were used to provide bands containing geometric information. The data were generated by Jeff Johnson, Johns Hopkins University Applied Physics Laboratory.

  4. Priyanka,

    Unfortunately the CRISM team has no plans to produce MTRDR products for CRISM observations acquired past May 21, 2012. The current processing that creates the MTRDRs also does VNIR/IR data joining and browse product generation using information from EPF sequences. Once the scanning gimbal started experiencing issues (limited or no EPF sequences), and especially after the IR heaters died (no IR data), using the current processing on those subsequent images became impossible.

  5. The XAS Spectra of Synthesized Glasses bundle has been released. These data have been added to the Spectral Library interface.

    This database includes X-Ray Absorption Near-Edge Structure (XAS) spectral data from a PDART investigation of synthesized glasses (DOI 10.2138/am-2016-5555). In this investigation, multivariate techniques were used to enable accurate XAS measurements of Fe, Cr, Mn, and Ti ratios across the whole spectral region through creation of a broad suite of experimentally homogenized glasses of geological relevance for use as XAS standards. Iron, Cr, Mn, and Ti were analyzed as epoxy-mounted polished glass beads using XAS at the GeoSoilEnviroCARS beamline at the Advanced Photon Source, Argonne National Laboratory using a spot size of ca. 1x1 μm.

  6. The Astromaterials Database bundle is posted.

    This bundle is a compendium of published geochemical data on astromaterials analyzed in terrestrial laboratories. The data were compiled by Kerstin Lehnert and colleagues as part of a PDART project now available online (https://www.astromat.org/) and further archived by the PDS Geosciences Node.

    The data may be accessed here:
