On March 11, the U.S. Mars Reconnaissance Orbiter (MRO) captured images of China's Zhurong as it flew 288 kilometers over the utopian plains, and it looked so clear that both wheel prints could be distinguished, and the resolution was significantly less than 0.3 meters.
It is clearer than the Zhurong photo taken by the mainland Tianwen-1 orbiter in recent days, which is nothing, the United States is the country with the strongest aerospace science and technology in the world, and it is more powerful than the mainland's aerospace science and technology, which is normal, after all, in the field of aerospace, the mainland started late.
Now, when the U.S. Mars Reconnaissance Orbiter flew over Jezero Crater, it captured 28G images of Mars in 6 seconds, showing the American Perseverance rover located northwest of Jezero Crater, and also showing a helicopter.
This helicopter is the first human helicopter to take off from Mars, named Witty, it and perseverance rover came to Mars, a total weight of about 1.8 kg, a total of four propellers, a diameter of 1.2 meters, up to 2400 revolutions per minute.
The Quichi helicopter flew for about 2 minutes in a single flight, with a flight speed of 3.85 meters, a flight altitude of about 10 meters, a maximum flight distance of about 400 meters, and a maximum stay in the air for about 129.2 seconds.
As of April 2022, the Witty Helicopter has completed its 23rd flight, with a cumulative flight time of more than 42 minutes, and now it is located 200 meters west of the Perseverance rover.
In March, the Perseverance rover completed the exploration of the first Mars mission site, collected seven Martian samples, and now Perseverance is driving around an old crater about 1100 meters in diameter to the second Mars mission site.
As of now, perseverance has traveled 7.07 kilometers, if you travel another 1.3 kilometers, you can reach the second Mars mission point, recently, perseverance updated the driving software, the daily travel distance has suddenly more than doubled, previously, a Mars day travel distance of no more than 200 meters, can now reach 400 meters.
The second Mars mission site is the remains of a delta located west of Jezero Crater, a raised plain about 15 square kilometers.
Hundreds of millions of years ago, Jezero Crater was once a circular lake up to 40 kilometers in diameter, with at least two large rivers flowing into the lake and an outflowing river, and the remains of the western delta were formed by the sediment carried by flowing water.
Therefore, the delta ruins are the most abundant area of material elements on Mars, if there has ever been life on Mars, then the delta ruins will be a paradise for life, perseverance to explore here, may be able to find traces of life.
