Based on the scientific objectives, nearly 60 proposals for rover instrumentation were evaluated and, on 31 July 2014, NASA announced seven scientific instruments that would make up the payload for the rover.

Planetary Instrument for X-Ray Lithochemistry (PIXL), an X-ray fluorescence spectrometer to determine the fine scale elemental composition of Martian surface materials.

Radar Imager for Mars' subsurface experiment (RIMFAX), a ground-penetrating radar to image different ground densities, structural layers, buried rocks, meteorites, and detect underground water ice and salty brine at 10 metres (33 ft) depth.
The RIMFAX is being provided by the Norwegian Defence Research Establishment (FFI).

Mars Environmental Dynamics Analyzer (MEDA), a set of sensors that measure temperature, wind speed and direction, pressure, relative humidity, radiation, and dust particle size and shape.
It will be provided by Spain's Centro de Astrobiología.

Mars Oxygen ISRU Experiment (MOXIE), an exploration technology investigation that will produce a small amount of oxygen (O
2) from Martian atmospheric carbon dioxide (CO
2).
This technology could be scaled up in the future for human life support or to make the rocket fuel for return missions.

SuperCam, an instrument suite that can provide imaging, chemical composition analysis, and mineralogy in rocks and regolith from a distance.
It is an upgraded version of the ChemCam on the Curiosity rover but with two lasers and four spectrometers that will allow it to remotely identify biosignatures and assess the past habitability.
Los Alamos National Laboratory, the Research Institute in Astrophysics and Planetology (IRAP) in France, the French Space Agency (CNES), the University of Hawaii, and the University of Valladolid in Spain cooperated in the SuperCam's development and manufacture.

Mastcam-Z, a stereoscopic imaging system with the ability to zoom.

Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC), an ultraviolet Raman spectrometer that uses fine-scale imaging and an ultraviolet (UV) laser to determine fine-scale mineralogy and detect organic compounds.

There are also a number of cameras, and for the first time on a Mars probe, two audio microphones will be used during the landing event, while driving, and when collecting samples.
