New processing algorithms have allowed inclusion of many observations that were previously rejected, and improved data fitting methods provide a significant improvement in data quality and a reduction in noise. The updated data products allow researchers to more accurately detect and measure the amount of water ice, carbon dioxide ice, and hydrated minerals in the first half meter below the surface of Mars. 2025-04-01 1.0 Initial version, alongside Release 91 MARS Odyssey Mission urn:nasa:pds:context:investigation:mission.2001_mars_odyssey document_to_investigation 2001 MARS ODYSSEY Host urn:nasa:pds:context:instrument_host:spacecraft.ody is_instrument_host NEUTRON SPECTROMETER Instrument urn:nasa:pds:context:instrument:ody.ns is_instrument Mars Planet urn:nasa:pds:context:target:planet.mars document_to_target 2021-04-01 Improved calibration and discrimination of neutron spectroscopy from 2001 Mars Odyssey PDF English 1 mons2_pds_final.pdf PDF
