  1. A new SHARAD derived data set is available from the PDS Geosciences Node. This is the first release of SHARAD Radargram data processed by the U.S. members of the SHARAD team. It includes data acquired from December 6, 2006 through December 15, 2007.

     

    This data set differs from the original SHARAD RDR data set in that a different set of processing parameters were used, the details of which are described in the Radargram Processing Document in the DOCUMENT directory of the archive. Future releases of this data set are planned to occur approximately monthly until the data coverage has caught up with the regular MRO release schedule.

  2. The fifth release of data from the GRAIL lunar mission is now online at the PDS Geosciences Node.

     

    This release includes new spherical harmonic models comprising data from both the primary and extended missions. In addition, all SPK data products have been revised and now include data from both the primary and extended missions. All new and revised data products can be found on the LGRS RDR archive volume. Please see errata.txt on that volume for more information.

  3. A new batch of data has been added to the Earth-based S-band Lunar Radar dataset available on the PDS Geosciences Node web site at http://pds-geoscienc...sband/index.htm. This data set contains dual-polarization backscatter maps of the lunar nearside collected at a wavelength of 12.6 cm (S-band), using the 305 m Radio Telescope at Arecibo to transmit and the NRAO's 105 m Robert C. Byrd Green Bank Telescope to receive. The data were provided by Bruce Campbell of the Smithsonian Institution's Center for Earth and Planetary Studies and archived by the PDS Geosciences Node.

  4. The fourth release of data from the GRAIL lunar mission is now online at the PDS Geosciences Node.

     

    This release comprises data from both the primary and extended mission phases and includes version 4 of LGRS EDR and CDR data, along with revisions to some RSS EDR data. It is also the first release of RSS EDR data from all other mission phases. New data products include wheel speed LGRS EDR and CDR products (WRS00, WRS1A, and WRS1B), as well as biased tracking data message standard (BTM) and biased open loop file (BOF) RSS EDR products.

  5. The NASA Planetary Data System announces the fourth release of the Analyst's Notebook for Mars Science Laboratory (MSL). The Analyst's Notebook combines sequence information, engineering and science data, and documentation for virtual mission replay.

     

    MSL Release 4 includes new raw and derived data acquired on sols 270 through 359, along with revised versions of some previously released data.

     

    The MSL Analyst's Notebook is available through the Geosciences Node at http://an.rsl.wustl.edu/msl.

  6. The third release of data from the GRAIL lunar mission is now online at the PDS Geosciences Node.

     

    This release includes derived lunar gravitational field data (LGRS RDRs), along with SPICE geometry and navigation kernels created by the GRAIL Science Data System (SDS).  The data were acquired during the primary mission phase, from 2012-03-01 through 2012-05-29.

  7. The NASA Planetary Data System announces the third release of the Analyst's Notebook for Mars Science Laboratory (MSL). The Analyst's Notebook combines sequence information, engineering and science data, and documentation for virtual mission replay.

     

    MSL Release 3 includes new raw and derived data acquired on sols 180 through 269, along with revised versions of some previously released data products from sols 0 through 89.

     

    The MSL Analyst's Notebook is available through the Geosciences Node at http://an.rsl.wustl.edu/msl.

  8. Here is some updated MSL traverse information from MSL Deputy Project Scientist Joy Crisp:

     

    (1) Approximate location maps are posted here - these will be updated more frequently, now that the rover has started its trek to Mount Sharp http://mars.jpl.nasa.gov/msl/mission/whereistherovernow/

     

    (2) The validated SPICE data archived in the Planetary Data System provides the rover location information based on telemetry (archived in 90-sol batches ~ 6 months after receipt of data on the Earth). These data are included in the MSL SPICE archive available in the NAIF node holdings:

    http://naif.jpl.nasa.gov/naif/data_archived.html

     

    To figure out how to use these data, you would have to copy the whole or a subset of the archive to your computer and study the archive documentation and the general information (tutorials, lessons) on the NAIF web site http://naif.jpl.nasa.gov

     

    (3) Unvalidated operations SPICE data files, providing up to the current Sol information, can be found here:

    http://naif.jpl.nasa.gov/pub/naif/MSL/kernels/

     

    Note however that the data in (2) and (3) can be off by a few meters or even few tens of meters from the actual position, which can be determined by careful manual examination of images from the rover and comparison to orbital images.

  9. The second release of data from the GRAIL lunar mission is now online at the PDS Geosciences Node.

     

    This release includes LGRS EDR, LGRS CDR, and RSS EDR data acquired during the extended mission phase, from 2012-08-30 through 2012-12-12 and RSS EDR data acquired during the decommissioning mission phase, from 2012-12-12 through 2012-12-18.

     

    The third release, which will include higher level derived products, is scheduled for October 11, 2013.

  10. The NASA Planetary Data System announces the second release of the Analyst's Notebook for Mars Science Laboratory (MSL). The Analyst's Notebook combines sequence information, engineering and science data, and documentation for virtual mission replay.

     

    MSL Release 2 includes new raw and derived data acquired on sols 90 through 179, along with revised versions of most previously released data products from sols 0 through 89.

     

    The MSL Analyst's Notebook is available through the Geosciences Node at http://an.rsl.wustl.edu/msl.
