In the 21st century today, the earth human beings are relying on the power of science and technology to conquer the Martian world, people have not yet been on Mars, a number of artificial objects have long arrived at the surface of Mars in advance, although artificial objects have lost contact, but there are still three man-made objects on the surface of Mars that can move freely, they are Perseverance, Zhu Rong and Curiosity.
As we all know, Perseverance, Zhurong and Curiosity are very intelligent Mars rovers, Zhurong is from China, Perseverance, Curiosity is from the United States, although the Perseverance rover came to the Mars world for only a short year, but it traveled 9.36 kilometers on the surface of Mars, to be described as running.
Since its successful landing in the spectacular Mars Jezero Crater on February 19, 2021, the Perseverance rover has been moving almost every Martian day since its successful landing at 4:55 a.m. on February 19, 2021, and in the first few months, the Mars Perseverance has moved slower during the commissioning phase, although the daily speed has increased significantly since the updating of the autopilot program.
The purpose of the Perseverance rover's landing at Jezero Crater was to explore the remains of the delta located in the northwest of Jezero Crater, because Jezero Crater was once a huge lake, and to the west of the delta ruins was a very large river, and the continuous stream of water brought a lot of mud, which was piled up at the entrance to form a "delta".
Delta believes that everyone is no stranger, such as the Pearl River Delta, the Yangtze River Delta and the Yellow River Delta on the mainland, the material in the delta region comes from the vast natural world, is the most mineral-rich area, it is also the favorite place of micro-life, and the same is true of the Mars Jezero Crater Delta.
There is a lot of evidence that wet ancient Mars has a vast ocean, and many scientists have long suspected that there have been oases on Mars, even movable life, and if mars really has life, then the Mars Jezero Crater Delta remnant area is the most likely place where life is probably present.
As of April 17, 2022, the Perseverance rover has spent 411 Martian days in the Mars Jezero Crater, running 9.36 kilometers, which is a very long distance for a rover, and according to the location of perseverance, the Perseverance rover has reached the foot of the Delta ruins.
Now, the Perseverance rover is moving around the foot of the delta ruins while scientists are exploring, and there are photos showing that the drill bit located at the front of the mechanical arm of the perseverance rover drills the Martian rocks from time to time to try to obtain samples, and when the exploration is enough, it will climb above the delta ruins to sample.
On April 16, the Perseverance rover took extraordinary landscape photos showing a corner of the delta ruins, which are tens of meters high, and after sun and wind erosion, there is a clear collapse, which also shows the barren and lonely side of the Martian surface, with brilliant sunlight everywhere, although there are mountains, but there are no trees and flowing water.
It is understood that this landscape photo comes from the Right Mastcam-Z camera of the Mars Perseverance rover, Mastcam-Z is a pair of cameras located high on the Mast of the Mars Rover, and it is also the pair of cameras with the most open field of view on the Perseverance, which has taken countless beautiful views, and this time it has taken extraordinary landscapes.
The Perseverance rover really likes to take pictures, because over the past year, perseverance has used multiple cameras to take pictures of the Martian landscape from multiple angles, with a front camera, a rear camera, a left camera and a right camera, taking a total of 237,000 photos of Mars, many of which look very interesting.
Perseverance's Mars photos seem to take us into a strange Martian world, and as the number of photos continues to increase, the strange Jezero Crater gradually becomes familiar, this is the Martian world we are about to colonize, and what worries us is that there is nothing here, more desolate than the desert of the earth, what do we rely on to survive?
In March 2022, Perseverance also did a special thing, that is, to monitor the sound on Mars, although Mars is very silent, not as lively and noisy as on Earth, there are still sounds, one is the sound of perseverance wheels driving, the other is the sound of whistling wind, do not forget that there is also a thin atmosphere on Mars.
The Martian atmosphere is too thin, and sound travels much more slowly in the atmosphere than on Earth, with sound waves traveling at a rate of about 340 meters per second in the atmosphere, but at a speed of about 240 meters per second in the Martian atmosphere, and the fastest is only 250 meters per second.
