The ExoMars Kazachok (formerly ExoMars 2020 surface platform) is a planned robotic Mars lander led by the Roscosmos, part of the ExoMars 2020 mission by the Roscosmos and the European Space Agency. Kazachok translates as "Little Cossack", and is also the name of a Russian folk dance.

The plan calls for a Russian Proton-M rocket to launch the Russian-built lander that will deliver the Rosalind Franklin rover to the surface of Mars. Once safely landed, the platform will deploy the rover and will start a one Earth-year mission to investigate the surface environment at the landing site.
The spacecraft was scheduled to launch in 2018 and land on Mars in early 2019, but due to delays in European and Russian industrial activities and deliveries of the scientific payload, it was moved to the launch window in July 2020.
- The Lander Radioscience experiment (LaRa) will study the internal structure of Mars, will help to understand the sublimation/condensation cycle of atmospheric CO2, and will make precise measurements of the rotation and orientation of the planet by monitoring two-way Doppler frequency shifts between the surface platform and Earth. It will also detect variations in angular momentum due to the redistribution of masses, such as the migration of ice from the polar caps to the atmosphere. Developed by Belgium.
- The Habitability, Brine, Irradiation and Temperature (HABIT) package will investigate the amount of water vapour in the atmosphere, daily and seasonal variations in ground and air temperatures, and the UV radiation environment. Developed by Sweden.
- Meteorological package (METEO-M). Developed by Russia. The instrument will incorporate the following sensor packages:
- Pressure and humidity sensors (METEO-P, METEO-H). Developed by Finland. The instrument have extensive heritage from those in the Curiosity rover, Schiaparelli lander and Phoenix lander.
- Radiation and dust sensors (RDM). Developed by Spain.
- Anisotropic magneto-resistance (AMR) sensor to measure magnetic fields. Developed by Spain.
- A magnetometer named MAIGRET, developed by Russia. The instrument will incorporate the Wave Analyser Module (WAM), developed by the Czech Republic.
- A set of cameras to characterise the landing site environment (TSPP). Developed by Russia.
- Instrument interface and memory unit (BIP). Developed by Russia.
- An IR Fourier spectrometer to study the atmosphere (FAST). Developed by Russia.
- Active Detection of Radiation of Nuclei-ExoMars (ADRON-EM). Developed by Russia.
- Multi-channel Diode-Laser Spectrometer for atmospheric investigations (M-DLS). Developed by Russia.
- Radio thermometer for soil temperatures (PAT-M). Developed by Russia.
- Dust particle size, impact, and atmospheric charging instrument suite (Dust Suite). Developed by Russia.
- A seismometer named SEM. Developed by Russia.
- Gas chromatography–mass spectrometry for atmospheric analysis (MGAP). Developed by Russia.
- Power source
The science and communication instruments on the lander platform will be powered by solar panels and rechargeable batteries. The automated voltage power system is being developed and build by ISS Reshetnev.
Russia previously evaluated the option of using a radioisotope thermoelectric generator (RTG) to power the science instruments, and a radioisotope heater unit (RHU) to provide thermal control while on the frozen Martian surface.
Landing site selectionEdit
On 21 October 2015, Oxia Planum was chosen as the preferred landing site for the ExoMars rover assuming a 2018 launch.
Since the launch was postponed to 2020, Aram Dorsum and Mawrth Vallis will also be considered. ESA convened further workshops to re-evaluate the three remaining options and in March 2017 selected two sites to study in detail:
The final selection is scheduled to occur approximately one year before launch.
