Because the map data was too huge to be transmitted, Tang Yue simply started to find the target by himself - he found the location of the Kunlun station and the Chelome probe on the map, and then drew a simulated travel route of the old cat, searching for locations in this corridor that might cause the Martian stray dog to capsize and overturn.

Tang Yue drove the Martian stray dog by himself, and he knew the performance of the Mars rover very well.

Lao Zheng's map is amazingly detailed, it is made up of three layers of images, with the Martian earth level as the reference zero point, accurately marking the altitude of each landmark in the plain, the price to pay to achieve this accuracy is huge, looking at Tang Yue began to wonder if anyone was preparing to use this area for military purposes, and Lao Zheng, a middle-aged bald man who seemed to be a lewd man, was actually on a secret mission and was an agent of a military intelligence department.

But after thinking about it, Tang Yue overturned this nonsensical speculation again, the remote sensing images of the Martian surface are completely public on the earth, and the world doesn't know how many students are counting on this thing to write a thesis and graduate, the Mars landing plan has been carried out for so many years, and every inch of land on the surface of Mars should be buried with a graduation thesis soaked in the blood and sweat of students.

Tang Yue is not clear or unpredictable whether the Mars program will have any other purposes in the future, but so far, the Mars program is still a huge scientific research and exploration project, and the main force is scientific research experts, engineers and professional astronauts, which is a commendable worldwide cooperation project. But as far as the urine of some people is concerned, they will definitely not invest money without a good return, and the Mars program is very expensive, and the sources of funds are huge, and there may be a shadow of the CIA.

But there is no future.

Without this map, Tang Yue and Mai Dong's work would have been difficult to carry out, and Tang Yue found problems at 22 kilometers, 41 kilometers, and 43 kilometers from the Chelome probe.

The first is a cliff, the exact location is 22.83 kilometers away from the landing site of the Chelome probe, its direction is almost perpendicular to the line between the probe and the Kunlun station, just on the way to the old cat, with a length of 1.2 kilometers.

The reason for the cliff is the unequal altitude on both sides, with the level of the Martian earth as the zero point of elevation, the altitude of the plain at the bottom of the cliff is 0.22 meters, and the altitude on the cliff is 3.37 meters.

"Hmm...... There is a drop of 3.15 meters, and if the old cat accidentally flips off it, such a high drop may break the rover antenna. ”

"Possibly." Mai Dong nodded, "The position on the Cherome's side is high, and the position on the Kunlun station side is low, so when you go, Mr. Cat can see the cliff, and it can go around, but when you come back, because the position of the Martian stray dog's cockpit is too high, and the view is not good, it may fall." ”

The second is a deep trench, the exact location of which is 41.46 kilometers from the Chelome probe.

"Mai Dong, you see, this ditch is more than six meters wide at the widest and more than four meters deep at the deepest, and it is also very suspicious." Tang Yue groaned, "Maybe the old cat will overturn in the gutter." ”

"Isn't Mr. Cat an old driver?" Mai Dong asked, "I heard that it is...... What mountain is the god of the car? ”

"Akinayama?"

"Yes, yes, it's the mountain." Mai Dong remembered, "Autumn Famous Mountain Racing God, Tang Yue, is Autumn Famous Mountain also a very famous racing track?" ”

"Yes, the Akinayama Stroller Global Rally Championship, a quadrennial event, the crown jewel of the world racing world." Tang Yue shrugged, "The old cat is the champion. ”

The girl only heard one champion clearly, and couldn't help but exclaim, "Wow——! ”

The third place is a steep slope on flat land, 43.69 kilometers away from the Chelome probe, it is more like a low mountain range than a steep slope, stretching for several kilometers, and the highest peak is tens of meters high - although the altitude is not high, the slope is extremely steep, the slope of sixty to seventy degrees is like a wall, only slightly better than the vertical up and down cliffs, no need to think about Tang Yue knows that this is far beyond the climbing ability of Martian stray dogs.

As long as the old cat has no problem with its brain, it will not challenge such a steep slope, and the correct choice should be to go around - but under normal circumstances, the old cat will not lose contact.

The most thing has already appeared, and Tang Yue can only speculate along the lines.

Tang Yue handed over the three coordinates to Mai Dong.

The next time the Joint Space Station passes over Kunlun, Mai Dong will only take precise photographs of these three positions, which is a much smaller task and can be done in one pass.

Mai Dong entered the coordinates into the computer, and she would definitely not be able to find the exact location on the surface of Mars with the naked eye.

Looking at the orbit at an altitude of 400 kilometers, the Cheromet probe and the Kunlun station, even the entire Ihidi Plain are only the size of a fingernail.

The last time Kunlun Station was hit by a storm, Mai Dong didn't notice it, because in her eyes the movement was too small.

In the space station's system computer, there is a whole set of geographical coordinates of Mars - similar to Earth, Mars has had its own coordinate system for a long time.

As early as the first half of the nineteenth century, astronomers tried to make a map of the surface of Mars, and the prime meridian of Mars was artificially defined as a circumferential curve passing through the Airy-0 crater in Meridian Bay.

However, the east and west longitudes of Mars are very different from those of the Earth - the Earth's coordinate system exists at the same time as east and west longitudes, with a maximum of 180 degrees each.

The Martian geographic system, on the other hand, uses either east or west longitude, which starts at zero degrees of longitude and extends east or west to 360 degrees, respectively.

The computer will find their location on the map in the database according to the coordinates entered by Mai Dong, and then guide the girl to point the optical tracking system at the target area.

The process sounds simple, but it takes a lot of skill and patience to operate, and despite observing a celestial object as large as Mars, Mai Dong feels like he is looking at paramecium with a microscope, and with a flick of the camera, he can no longer find his target.

The girl's eyes were close to the eyepiece again, and in the state of large field of view and low magnification, she turned the knob to adjust the direction of the lens, and the eyepiece had clear cross divisions and parameters, like an advanced sniper rifle scope in the movie, and like a heads-up display in the old cockpit of a fighter jet.

The numbers are jumping in green, and the Joint Space Station is flying over the target.

Mai Dong took a deep breath and turned on the camera.

Three hours later.

Tang Yue and Mai Dong both fell silent, Tang Yue sat in the hall, looking at the images on the computer screen, puzzled...... How is this possible? How the fuck is this possible? Did that cat evaporate from the world? Such a big cat, such a long dog, how can you say that if you don't see it, you're gone?

After careful searching, Mai Dong and Tang Yue finally confirmed that the old cat did not overturn under the cliff, did not overturn in the ditch, and did not overturn at the bottom of the slope, Tang Yue was eager to turn every pixel of the photo over and over again to find it three times, but unfortunately, there was no trace of the old cat under the cliff, and there was no trace of foreign object activity in the deep ditch and steep slope - Tang Yue's excitement and enthusiasm turned into cold disappointment.

If even the old cat of the cliff and ditch crossed it unharmed, then why did it lose contact for no reason? Could it really be that it was flattened and overturned?

When did the Martian stray dog have more attributes of flat falls?

Tang Yue...... Maybe Mr. Cat has a problem somewhere else, or maybe there's something missing, and we'll continue to look elsewhere? Mai Dong asked.

Tang Yue didn't speak, he tore off a blank piece of scratch paper, folded it in half, and then pulled out his pen.

"What do you want to do?"

"I'm going to make a tablet." Tang Yue unscrewed the cap.

"What tablet?"

"The tablet of the gods and Buddhas."

"Didn't you say that praying to God and worshipping Buddha doesn't work? God is dead, and we are on our own. Mai Dong said, "Why do you still need to make tablets? ”

"The tablet doesn't have to be for worship." Tang Yue wrote a few big words on the white paper, "Thief God".

Then he put the white paper on the table and shouted angrily: "Die, thief! See you again! Then he slammed it on the floor and stomped on it twice.

The tablet does not necessarily have to be used for worship.

It can also be used to whip corpses.
