Perseverance is a rover developed by NASA as part of the Mars 2020 mission and landed on the Red Planet on February 18, 2021. The main objective of the rover is to search for astrobiological signs of life on the Martian surface, analyze regions that may have hosted life in the past, collect data on Mars' geology and climate, and prepare for future human missions. Perseverance was designed based on the experiences gained from NASA's previous Mars missions.

Technical Specifications
Dimensions and Structure
Perseverance shares a similar chassis with NASA’s previous rover, Curiosity, but was developed with some structural differences. The rover is approximately 3 meters long, 2.7 meters wide, and 2.2 meters tall. It weighs about 1,025 kilograms.
Power System
Perseverance meets its energy needs using a radioisotope thermoelectric generator (MMRTG). This system converts the heat produced by the natural decay of plutonium-238 into electrical energy. MMRTG is essential for long-term operation in the harsh conditions of Mars and offers a more stable energy source compared to solar power.
Mobility
The rover has six wheels, each of which can move independently. This structure provides high maneuverability on rough terrain. Its suspension system is of the "rocker-bogie" type, which helps maintain stability on the Martian surface.

Scientific Payload and Instruments
SuperCam
Composed of a high-resolution camera, laser, and spectrometer systems, SuperCam analyzes the composition of rocks and soil samples. It enables microscopic-scale examination of surfaces using laser pulses.
SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals)
This system detects organic compounds and minerals using an ultraviolet laser. It also scans for biologically important molecules that could indicate potential signs of life.
PIXL (Planetary Instrument for X-ray Lithochemistry)
PIXL is an X-ray fluorescence spectrometer used to determine the chemical composition of surface rocks. It has the capability to conduct analyses at sub-millimeter levels.
MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment)
MOXIE is a technology demonstration device that attempts to produce oxygen from the carbon dioxide in Mars' atmosphere. It represents an important step in supporting life and fuel production for future human missions.
RIMFAX (Radar Imager for Mars' Subsurface Experiment)
RIMFAX, a ground-penetrating radar system, enables mapping of subsurface structures. It provides information about features up to 10 meters deep.
Mission and Objectives
Astrobiological Investigation
One of Perseverance’s main goals is to search for signs of past life on Mars. For this purpose, Jezero Crater was chosen, as it hosts an ancient river delta and contains geomorphological evidence indicating the past presence of water.
Sample Collection and Storage
The rover collects rock and soil samples and stores them in special capsules. These samples are planned to be brought back to Earth by a future mission (Mars Sample Return program).

Preparation for Future Human Missions
Systems like MOXIE serve as tests for establishing life support systems on Mars. Additionally, Perseverance's landing system and overall operations allow for testing technologies that will be used in human missions.
Ingenuity Helicopter
Ingenuity, a small helicopter sent to Mars along with Perseverance, became the first vehicle to achieve controlled flight on another planet. This technology demonstration proved that aviation applications are possible in the Martian atmosphere. The helicopter plays a supporting role in Perseverance’s environmental exploration missions.

Scientific Contributions and Initial Findings
In surface scans conducted in Jezero Crater, Perseverance confirmed the presence of sedimentary rocks and provided evidence supporting the long-term presence of water in this area. Organic molecules have been detected in some rocks, though it is not yet determined whether these molecules are of biological origin.

Additionally, thanks to the MOXIE system, oxygen has been successfully extracted from the Martian atmosphere. This development demonstrates the feasibility of the in-situ resource utilization concept on Mars.
Perseverance is one of the most significant tools in the history of Mars exploration. With its technologically advanced equipment and multi-purpose scientific objectives, it provides new and detailed data about Mars. It is an important experimental platform for astrobiology, geology, atmospheric science, and engineering. The data it collects is critically important for understanding the evolution of Mars and planning future human missions.
