What are the main scientific explorations of the "Perseverance" rover landing on Mars?

The main task of the "persistent rover" landing on Mars is to find signs of ancient life, explore water sources and collect samples of Martian soil and rocks. But he is also in charge of a series of other scientific experiments, including the experiment on the utilization of Mars oxygen field resources (Mo Xie), which uses 95% carbon dioxide in the Martian atmosphere to produce oxygen. In this historic test, the small box electrolyzer carried by the rover produced 5.4 grams of oxygen in one hour, which is equivalent to a normal astronaut needing about 10 minute of oxygen. According to the design goal, the instrument can produce 12g oxygen per hour, or about 288g oxygen per day.

It is said that astronauts on the International Space Station consume an average of 840 grams of oxygen every day. This is an important first step to convert carbon dioxide into oxygen on Mars, which will make the future human task more feasible. Michael Hector, a principal researcher at the Mo Xie Observatory, told the rockets and astronauts that oxygen is very important. In future missions, if four astronauts want to leave the surface of Mars, they need 15000 pounds of rocket fuel and 55000 pounds of oxygen. An astronaut staying on the surface of Mars for one year may inhale 2200 pounds of oxygen.

Installing the rover for one hour can produce 5.4 grams of oxygen, which is almost equivalent to the 10 minute oxygen consumption of astronauts' normal activities. Future astronauts need to perform tasks on Mars and consume one ton of oxygen to meet the needs of one year. The epoch-making oxygen experiment on Mars is of great significance to astronauts' respiratory oxygen consumption and rocket fuel. NASA's Witt unmanned helicopter made its first helicopter flight on the surface of Mars.

The flying time of the Mars helicopter is about 40 seconds, and the flying height is about 3 meters, which is equivalent to flying over the earth about 30,000 meters, which is beyond the reach of helicopters on the earth. Created a new era of human exploration of Mars. The environment of Mars can be compared with the Gobi desert, where the air on the earth is thin, but the environment is worse. Historically, Mars has abundant water resources and a thick atmosphere. Billions of years ago, Mars may be an environment suitable for life. However, even if there are substances that can sustain life on Mars, human migration to Mars is still a big and complicated proposition. Mainly because the environment on Mars is so bad. When you immigrate to Mars, you can only build a small laboratory on Mars at the beginning to create a livable environment for human beings indoors.
