Returned Sample Science
April 12, 2022. The
Returned Sample Science (RSS) archive consists
of sample dossiers, collections of
science and engineering data relevant to each
sample acquisition, along with associated
documentation. Dossiers for the first four samples are currently
in preparation for peer review and delivery to PDS.
The dossiers will have links to the relevant data
products--images and other instrument
observations--that already exist elsewhere in the
While the archives are in
preparation, the Mars 2020 Project has released the
Initial Reports for samples 1
through 4, below.
The Returned Sample Science
(RSS) Archive contains information related to remote sensing and
contact science observations of targets that
are drilled and for which samples are cached
on the surface. The archive provides
scientific context for the samples, and documents what was done during drilling,
including the exact location, appearance of
the target before and after drilling, and
measurements of currents and other
engineering parameters associated with
drilling. The archive also documents the
locations and physical characteristics of
cache points for future retrieval.
The Initial Reports are near-real-time
records of activities surrounding sample
acquisition, analogous to field notes. They
are preliminary, and the interpretations and
even some of the underlying measurements
will be revised and described more fully in
detailed follow-on publications.
The Initial Reports are provided here as
soon as they are made available by the Mars
2020 Project. They will ultimately be
incorporated into the PDS sample dossier
archives, which are currently being
assembled and reviewed.
