It has been three years since the introduction of the robotic vehicle. Perseverance traveled to explore Mars with the Ingenuity helicopter, which made its 72nd and final flight over the surface of Mars on January 18. Perseverance successfully completed the journey. It is about the size of a car and equipped with seven scientific instruments, including the RIMFAX radar, which uses radar signals every 10 centimeters on the planet's surface and is now providing valuable data for mapping reflected vibrations from a depth of about 10 centimetres. 20 meters below the surface of Jericho Crater on Mars.
Radar maps revealed the presence of deposits that were suspected in previous studies of Mars. But this has not been confirmed before. The presence of sediments indicates that the Jezero Basin was once flooded and a giant lake formed. Sediments move along rivers and form large deltas similar to those found on Earth. Before sediment accumulated and was later eroded by erosion in two different periods. Discovery of ancient lake sediments beneath the Perseverance site A robotic rover could potentially scrape up microbial fossils. But this must be proven in order for the samples to be returned to Earth.
However, life on Earth depends on water to survive. If there is evidence that water actually existed on Mars, this could be important evidence that the Red Planet was once inhabited by life. Or perhaps organisms still exist.
