Spectroscopy (LIBS), Time-Resolved Raman and Luminescence (TRR/L), Visible and Infrared Spectroscopy (VISIR), together with sound recording (MIC) and high-magnification
imaging techniques (RMI). They provide information on the mineralogy, geochemistry and
mineral context around the Perseverance Rover.
The calibration of this complex suite is a major challenge. Not only does each technique
require its own standards or references, their combination also introduces new requirements
to obtain optimal scientific output. Elemental composition, molecular vibrational features,
fluorescence, morphology and texture provide a full picture of the sample with spectral
information that needs to be co-aligned, correlated, and individually calibrated.
The resulting hardware includes different kinds of targets, each one covering different
needs of the instrument. Standards for imaging calibration, geological samples for mineral
identification and chemometric calculations or spectral references to calibrate and evaluate the health of the instrument, are all included in the SuperCam Calibration Target
(SCCT). The system also includes a specifically designed assembly in which the samples
are mounted. This hardware allows the targets to survive the harsh environmental conditions of the launch, cruise, landing and operation on Mars during the whole mission. Here
we summarize the design, development, integration, verification and functional testing of
the SCCT. This work includes some key results obtained to verify the scientific outcome of
the SuperCam system.

1 Introduction
The Mars 2020 mission and its Rover, Perseverance, will continue NASA’s efforts in the
exploration of Mars and the search for life on that planet (Mustard et al. 2013). Three of
the four main objectives of the mission are related to the search of biosignatures on Mars:
to study the geology of the planet and its habitability, to look for potential biomarkers or
reservoirs where they could be preserved, and to collect documented samples for a future
Mars Sample Return Mission (Farley et al. 2020, this issue). Perseverance leverages the
architecture of the Curiosity rover (Mustard et al. 2013), and its heritage is extended to part
of the payload, with SuperCam being an example (Wiens et al. 2020; Maurice et al. 2020,
this issue).

SuperCam is a standoff instrument, designed to be a multianalytical suite of five coaligned techniques: Laser-Induced Breakdown Spectroscopy (LIBS), Time-Resolved Raman and Luminescence (TRR/L), Visible (VIS) and Infrared (IR) Spectroscopy (VISIR),
Remote Micro-Imaging (RMI) and sound recording (MIC). For detailed descriptions of
these techniques, see Maurice et al. (2020, this issue) and Wiens et al. (2020, this issue).
This suite, with the synergistic use of all of its techniques, makes SuperCam a cornerstone
tool for operational decisions regarding the rover’s actions and traverse, as it extends scientific exploration far beyond the range of action of the robotic arm.
The instrument is composed of three main subsystems: the Body Unit is located inside
the body of the rover and contains the three spectrometers used for LIBS, Raman and luminescence, and the VIS range of passive spectroscopy (Wiens et al. 2020, this issue). The
Mast Unit is located at the top of the mast, above Mastcam-Z and Navcams, and includes the
laser, focusing and collection optics, the microphone, the imager, and (...truncated)
