How did the Mars Gate photographed by Curiosity form?

The Mars Gate photographed by Curiosity really gives people a lot of imagination. It seems that its first thought is that this seems to have been seen there. Later, it suddenly occurred to me that there was such a hole when Xia Zi first met the Supreme Treasure. Later, Xia Zi waved three words to the door of this cave, which was called "Pansi Cave". Boy, I wonder if there is a sad love story behind this Mars Gate?

Aside from the bold imagination of netizens, there are two theories in the scientific community about the cause of this Mars Gate.

1. Caused by the earthquake

Earthquakes are frequent on Mars, and we have recorded them many times. The latest earthquake we know at present happened on May 4th this year. The collapse of surrounding rock caused by earthquake may produce many famous landforms or external shapes on the surface.

2. The result of natural corrosion

For the first statement, the second explanation feels more reliable. Because this structure that looks like a "door" is a gap in the rock, Neil Hodgson, a British geologist who studies the geology of Mars, said that the rock layer may have been deposited under the sedimentary conditions of 4 billion years ago, or it may be in a river or a sand dune blown by the wind. After these rock formations are exposed to the surface, they are eroded by the Martian wind, and even some traces of erosion can be seen in the "door" in the photo. In addition, some natural vertical faults can be seen in the photo, which may be related to the unique fracture mode formed by weathering of Martian rocks, and this "gate" seems to be formed at the intersection of vertical faults and strata.

After listening to the experts, do we feel a little discouraged? Are the good sites for alien civilization and extraterrestrial bases gone like this? In fact, our alien detection instrument has brought us more surprises than this. We are familiar with it three times:

In 1977, NASA's Viking 1 spacecraft took a picture that looked like a human face. At that time, it was speculated that Martians had built a monument similar to the Sphinx. But what about the result? 1 1 years later, NASA took an image that was 10 times clearer than the original photo, and found that this so-called "face" was just an ordinary rock, and the original facial features were actually caused by shadows.

On February 28th, 2009, at 65438, the high-resolution imaging science experiment (HiRISE) camera on NASA's Mars reconnaissance orbiter captured this photo. At first glance, it looks like rows of trees rising from the sand dunes in waves, much like the farmland we see in the countryside. However, this is only an optical illusion. In fact, they are horizontal organizations composed of basaltic sand, which seem to have changed in business, but under the action of sunlight, we feel more stereoscopic.

At the end of 20021,the "Yutu II" lunar rover photographed a "mysterious cabin" on the surface of the moon. Under the deep sky, an abrupt cube appears on the skyline on the north side of the photo. Because of the distance, netizens speculated that this "mysterious hut" might be created by aliens. This photo once attracted widespread attention, but the vast number of China netizens took their imagination to the extreme, such as Guanghan Palace, Alien Base, Jade Rabbit Nest and so on. Later, with the continuous advancement of the lunar rover, the distance from this "mysterious cabin" has been narrowing. In June this year, it was finally confirmed that it was just a stone. The seemingly perfect geometry in the distance is just a trick of angle and light and shadow.

So, why are humans so keen to explore Mars? Mainly for the following two reasons:

1. Mars may be the most reliable home for human beings to want interstellar migration.

Because the atmosphere of Mars is very thin, only equivalent to 1% of that of the earth, its ultraviolet radiation is also extremely intense. This also leads to a huge temperature difference between day and night on Mars. In the equatorial region where the temperature changes the least, it can be 20 degrees Celsius during the day and 70 degrees below zero at night. However, this change is the closest to the earth among the terrestrial planets. In addition, the rotation period of Mars is 24 hours and 39 minutes, which is similar to human biological clock, and Mars has four seasons, which is one of the reasons why Mars has become the first choice for immigrants.

And after so many years of continuous exploration of Mars, it is found that there are oceans and very rich water resources on Mars. In 20 18, NASA discovered that there was liquid water under the Antarctic cover of Mars. If there was a volcanic eruption on Mars, it can be proved that there was a thick atmosphere on this planet, which is also a necessary factor for the formation of life.

Second, human civilization may have originated from Mars.

In the 1990s, meteorites from Mars were discovered at the South Pole of the Earth. Through careful study by scientists, there are bacterial fossils on the surface of these Martian meteorites. 20 13 Steven Benner, a professor at Harvard University, studied these fossils and concluded that life on earth probably came from Mars. The scientist believes that boron and molybdenum, which produce DNA and RNA, are not found in nature on earth, but there are many such substances on Mars, which means that life on earth may have migrated from Mars.

Human exploration of space will continue to develop in a deeper and wider direction. It is conceivable that at some point in the future, mankind will be able to uncover two mysteries that have puzzled us for thousands of years. Where do we come from? Where are you going again? But there is no need for human steps to stop. The universe is too big, life is endless, and exploration is endless!
