Crater arrival as an example of the ancient delta
Mars soil samples to be collected and stored

The US Mars exploration rover (mobile exploration robot)’Perseverance’ has successfully landed on Mars and set out on a mission to find traces of life.
According to the Associated Press on the 18th (local time), NASA’s fifth Mars exploration rover Perservation settled in’Jezero Crater’, which is believed to be the ancient delta of Mars.
After launching on July 30 last year, Perseverance flew 475 million kilometers to reach Mars. NASA reported that Perseverance passed through the pale orange Mars atmosphere and passed through the most dangerous missions.
The process of entering, descending, and landing (EDL) in Mars’ atmosphere is called the ‘7 minutes of horror’ because of the most demanding and high-risk flight of Perservance. Due to the long distance between Mars and Earth, the Mars settlement signal sent by Perservance to the NASA control station reached Earth 11 minutes and 30 seconds after landing.
Perseverance will be tasked with finding traces of ancient life that may have existed on Mars and collecting soil and rock samples to bring to Earth. As an example of where Perservance landed, the crater is estimated to be the delta where the river flowed from 3 to 4 billion years ago, and it is expected that traces of organic molecules and other microorganisms can be found.
Equipped with equipment that can find organic matter and analyze rocks and soil components, Perseverance collects soil and rock samples, puts them in dozens of titanium tubes, and stores them in a promised place on Mars.
The samples will be collected by another rover that will be launched later, delivered to another spacecraft, and sent to Earth in 2031. On Earth, samples are analyzed with equipment such as a high-performance microscope to study the existence of life. Along with this, Perservance will be tasked with preparing for a manned expedition to Mars.
