SAM (Sample Analysis at Mars)
August 19, 2021.
Missing QMS products have been added to the SAM RDR
data set. See
errata.txt for more information.
August 3, 2021. SAM EDR data for sols
2935-3068 have been added to the
SAM EDR safed data set.
August 2, 2021.
MSL Release 27 includes new SAM derived (RDR) data
from sols 2935-3068, November 7, 2020 -
March 24, 2021.
The Sample Analysis at Mars (SAM) instrument suite
includes a mass spectrometer, a gas chromatograph, and a
tunable laser spectrometer. The mass spectrometer will
separate elements and compounds by mass for
identification and measurement. The gas chromatograph
will heat soil and rock samples until they vaporize, and
will then separate the resulting gases into various
components for analysis. The laser spectrometer will
measure the abundance of various isotopes of carbon,
hydrogen, and oxygen in atmospheric gases such as
methane, water vapor, and carbon dioxide. SAM data sets
are produced by the SAM Team at Goddard Space Flight

Raw Data Products
SAM raw (EDR) products are
safed, but not formally archived in PDS. They
have not been peer-reviewed and are not considered
Certified Data by PDS.
Users considering the
SAM EDR data set are recommended to use the
lowest-level RDR data set instead. This RDR product
contains the same data as the EDR but with
non-science-related telemetry removed.
SAM EDR safed data set is
made available here.
