Through the high-definition photos of Mars, we can see that Mars is extremely barren, but whether there is life on Mars is not quite certain, and now, three Mars rovers are looking for three suspected areas of life on Mars, which are The Chinese Zhurong, the American Perseverance and the American Curiosity.
Mars not only has three rovers, but also a Mars helicopter, called Witty, which is not a manned helicopter, but a small helicopter like a "children's toy", because it weighs only 1.8 kilograms, and the one-time flight distance is only a few hundred meters, and the flight altitude is only tens of meters.
Mars helicopters can fly on the surface of Mars, which also proves that Mars has an atmosphere, but the atmosphere of Mars is extremely thin and cannot be directly breathed by humans, and there have been previous research reports that the thickness of the Martian atmosphere is only 1% of the Earth's atmosphere.
The atmosphere is so thin, the buoyancy is not very large, far less buoyant than the earth's atmosphere, so the Witty helicopter is not easy to fly, in the past 1 year or so, a total of 26 flights, each flight is only a few minutes, the flight distance is only tens of meters to hundreds of meters, always around the Perseverance Mars rover.
The 26th flight of the Witty Helicopter was on April 19, 2022, when the Witty flew to an altitude of tens of meters, it photographed a broken dish, what is it?
When it comes to saucers, it is easy to think of UFOs, when so many probes and rovers land on Mars, the existence of man-made objects on Mars is not a new thing, this is indeed a broken dish, but not a UFO, but an artificial object.
Recently, NASA showed the disc taken by the Witty, in order not to make people mistakenly think that it is a UFO, specially explained the broken dish, which is actually the back cover when perseverance landed on the surface of Mars.
Perseverance landing on Mars also has to go through "horror 3 minutes", Perseverance flies to the surface of Mars with great speed, and the violent friction of the atmosphere makes the outer surface of Perseverance produce thousands of degrees Celsius of high temperature, especially at the bottom, at this time Perseverance needs a heat shield to protect.
Perseverance's heat shield has two, one is the bottom cover, the other is the back cover, they are all in the shape of a dish, the two together are just like the flying saucer we imagined, the production process of the bottom cover is more demanding, requiring both hardness and heat insulation, and the back cover requirements are not so high.
The final stage of Mars landing on Mars is to use a parachute to slowly descend to the surface of Mars, and at an altitude of several kilometers from the surface of Mars, Perseverance will throw away the back cover and the underbody in order, so the back cover and the bottom cover will fall directly to the surface of Mars, so that the high drop will definitely smash into pieces.
I don't know if you have found that there is a parachute on the ground near the perseverance back cover, which is the parachute abandoned after the successful landing of the perseverance, which once again confirms that the disc in the photo taken by the Wit is determined to be the perseverance back cover, and there is nothing worth doubting.
For more than a year, the Wit helicopter has always flown near the Perseverance, is it that the Wit helicopter cannot fly independently? It is true that the Witty helicopter does not have the ability to fly independently, and if it is too far away from perseverance, it will lose contact.
It should be known that the Witty helicopter weighs only 1.8 kg, so it is impossible to carry a high-power communication instrument, communicate directly with the Mars Orbiter, and can only communicate with the Perseverance rover through a smaller power communication instrument, so its distance from perseverance cannot be too far, and the farthest distance cannot exceed 1 km.
In addition, the Martian air is so thin, the stability is poor, it may be thicker here, and it should be thinner there, so that the Witty helicopter flight is not so smooth, and it is not good to turn over, at this time it needs perseverance to help, to know that perseverance has two mechanical arms, a large mechanical arm, and another small mechanical arm.
There is no way, Perseverance can only take the small Wit to find life, anyway, Wit can also play a complementary role in Perseverance's exploration of Mars.
Now, the Perseverance rover has traveled nearly 11 kilometers, has come to the foot of the delta area, and walked around the foot for a week, and is expected to board the delta in the near future to look for possible life in the delta, which will take a while.
