Kazachok Lander: Scientific Instruments and Payload Capabilities
The Kazachok lander project, led by Roscosmos, was designed as a sophisticated scientific outpost on the Martian surface. To achieve its mission goals, the lander was planned to carry a diverse scientific payload weighing approximately 45 kg. This suite of instruments represented a collaborative international effort, combining Russian leadership with critical contributions from European partners to analyze the planet's internal structure, atmosphere, and habitability.
Key Facts
- Lead Agency: Roscosmos (Russia).
- Total Payload Mass: Approximately 45 kg.
- International Collaboration: Contributions from Belgium, Sweden, Finland, Spain, the Czech Republic, Bulgaria, Italy, and France.
- Primary Goals: Studying Martian internal structure, atmospheric composition, and surface environment.
- Power Systems: Solar panels and rechargeable batteries, with previous evaluations for RTG and RHU options.
Atmospheric and Environmental Monitoring
A significant portion of the Kazachok payload was dedicated to understanding the Martian atmosphere and the radiation environment. The HABIT (Habitability, Brine, Irradiation and Temperature) package, developed by Sweden, was designed to measure UV radiation, water vapor, and temperature fluctuations in both the air and ground.
Complementing this was the Meteorological package (MTK), led by Russia. This comprehensive suite included pressure and humidity sensors from Finland—utilizing heritage from the Curiosity, Schiaparelli, and Phoenix missions—as well as a meteorological boom featuring wind sensors and solar irradiance and dust sensors developed by Spain.
Further atmospheric analysis would have been conducted via the FAST (IR Fourier spectrometer) and the M-DLS (Multi-channel Diode-Laser Spectrometer), both developed by Russia. Additionally, the MGAK (Gas chromatography–mass spectrometry) unit was intended for detailed atmospheric chemical analysis.

To peer beneath the surface, the lander would have employed the Lander Radioscience experiment (LaRa). Developed by Belgium, LaRa aimed to study Mars' internal structure and the sublimation and condensation cycle of atmospheric CO2. By monitoring two-way Doppler frequency shifts between Earth and the lander, it could measure the planet's rotation and detect mass redistributions, such as ice migrating from polar caps to the atmosphere.
Other geophysical tools included the MAIGRET (MArtIan GRound Electromagnetic Tool) magnetometer package, which featured a Wave Analyser Module from the Czech Republic, and a Russian-developed seismometer (SEM) to detect tectonic or impact activity.
Surface and Radiation Sensing
The lander's ability to characterize its immediate surroundings relied on the TSPP, a set of four Russian cameras. For radiation study, the ADRON-EM (Active Detection of Radiation of Nuclei-ExoMars) included a pulsed neutron generator and a radiation dosimeter provided by Bulgaria.
Additional surface instruments included the RAT-M radio thermometer for soil temperature and the PK suite for dust particle analysis, which incorporated contributions from Italy (MicroMED) and France (electrical conductivity sensor). Finally, Italy provided the INRRI (Instrument for landing/Roving laser Retroreflector Investigations).
[ไม่มีภาพประกอบ]Power and Technical Infrastructure
The operational capacity of these instruments depended on a robust power system. The lander was designed to be powered by solar panels and rechargeable batteries, with the automated voltage power system developed by ISS Reshetnev.
During the planning phases, Russia evaluated the use of a Radioisotope Thermoelectric Generator (RTG) for power and a Radioisotope Heater Unit (RHU) to maintain thermal control against the extreme cold of the Martian surface.
