Die on Mars

Since the map data was too huge and inconvenient to transmit, Tang Yue simply started to find the target himself - he found the locations of the Kunlun Station and the Chelome detector on the map, and then drew the simulated route of the old cat. Search this corridor for locations that might cause the Martian Stray Dog to tip over.

Tang Yue drove the Mars Stray Dog himself, and he knew the performance of that Mars rover very well.

Lao Zheng's map is astonishingly detailed. It is made up of three layers of overlapping images. It uses the ground level of Mars as the reference zero point and accurately marks the altitude of every landmark in the plain. The price to pay for achieving this kind of accuracy It was huge. Looking at it, Tang Yue began to wonder if someone was planning to use this area for military purposes. Lao Zheng, a middle-aged bald man who looked like a wretched man, was actually on a secret mission and was a military officer. Agents of the intelligence services.

But on second thought, Tang Yue overturned this nonsensical speculation. Remote sensing images of the surface of Mars are completely public on Earth. Countless students around the world relied on this to write their thesis and graduate, and the Mars landing plan was launched. After so many years, there should be a graduation thesis soaked in the blood and sweat of students buried under every inch of the Martian surface.

Tang Yue doesn't know whether the Mars project will have any other purposes in the future, and he can't predict it. But so far, the Mars project is still a huge scientific research and exploration project. The main force is scientific research experts, engineers and professional astronauts. It is worth Praise for collaborative projects around the world. But for some people, they will definitely not invest money without a huge return. The Mars project costs a lot of money and has a variety of funding sources, including the CIA.

But there is no future.

Without this map, the work of Tang Yue and Maidong would be very difficult. Tang Yue discovered problems at 22 kilometers, 41 kilometers and 43 kilometers away from the Chelome probe.

The first one 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 connection between the probe and the Kunlun Station, and it just blocks the path of the old cat, with a length of 1.2 kilometers.

The reason for the formation of the cliff is that the altitude on both sides is different. Taking the ground level of Mars as the zero point of altitude, the altitude of the plain at the bottom of the cliff is 0.22 meters, while the altitude on the cliff is 3.37 meters.

"Well... there is a drop of 3.15 meters. If the old cat accidentally rolls over, such a high drop may break the rover antenna."

"It's possible." Maidong nodded, "The location of the Chelome ship is high, and the location of the Kunlun station is low, so Mr. Cat can see the cliff when he goes there, and he can go around it, but when he comes back, due to The cockpit of the Mars Stray Dog is too high and the view is not good, so it may fall."

The second place is a deep trench, the exact location is 41.46 kilometers away from the Chelome detector.

"Look at Ophiopogon japonicus, this ditch is more than six meters wide at its widest and more than four meters deep at its deepest point. There is a lot of suspicion." Tang Yue pondered, "Maybe the old cat overturned his car in the ditch."

"Isn't Mr. Cat an experienced driver?" Maidong asked, "I heard that he is... the god of cars in some mountain?"

"Qiu Mingshan?"

"Yes, it's this mountain." Maidong remembered, "Qiu Mingshan, the racing god, Tang Yue, is Qiu Mingshan also a very famous racing track?"

"Yes, the Qiu Mingshan Stroller Global Rally Championship is held every four years and is the crown jewel of the world's racing world." Tang Yue shrugged, "Old Cat is the champion."

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

The third point is a steep slope on the flat land, 43.69 kilometers away from the Chelome probe. It is a steep slope rather than a low mountain range, stretching for several kilometers. The highest peak is tens of meters high - although the altitude is not high. It is high, but the slope is extremely steep. The slope of 60 to 70 degrees is like a wall, only slightly better than a vertical cliff. Tang Yue doesn't need to think about it to know that this is far beyond the climbing ability of a stray dog ​​on Mars.

As long as there is nothing wrong with the old cat's brain, it will not challenge such a steep slope. The correct choice should be to go around - but under normal circumstances, the old cat will not lose contact.

The most ridiculous thing has appeared, and Tang Yue can only speculate along the nonsense.

Tang Yue handed over the three coordinates to Ophiopogon japonicus.

The next time the Joint Space Station passes over Kunlun Station, Maidong will only take precise photos of these three locations. This workload is much smaller and can be completed in one pass.

Maidong entered the coordinates into the computer. She would definitely not be able to find the exact location on the surface of Mars with her naked eyes.

Viewed from an orbit of 400 kilometers, not to mention the Chelome probe and the Kunlun Station, even the entire Ixi plain is only as big as a fingernail.

The last time Kunlun Station encountered a storm, Maidong didn't notice it because the movement was too small in her eyes.

In the system computer of the space station, there is a complete set of geographical coordinates of Mars - similar to the Earth, Mars also had its own coordinate system a long time ago.

As early as the first half of the 19th century, astronomers tried to make a map of the surface of Mars. The prime meridian of Mars was artificially defined as a circular curve passing through the Meridian Bay Airy-0 crater.

However, the east longitude and west longitude of Mars are very different from those of the Earth - the earth's coordinate system has both east longitude and west longitude, and the maximum is 180 degrees each.

The Martian geographical system uses either east longitude or west longitude, which starts at zero degrees longitude and extends east or west to 360 degrees respectively.

The computer will find their locations on the map in the database based on the coordinates input by Ophiopogon japonicus, and then guide the girl to point the optical tracking system to the target area.

This process sounds simple, but it requires skills and patience to operate. Although he is observing a huge celestial body like Mars, Maidong feels like he is observing a paramecium with a microscope. When the lens shakes, he can no longer find it. Target.

The girl's eyes were once again close to the eyepiece. With a large field of view and low magnification, she turned the knob to adjust the direction of the lens. There were clear cross divisions and parameters on the eyepiece, like an advanced sniper scope in the movie or a fighter jet. HUD in an old-school cockpit.

The green numbers are beating, and the United Space Station is flying over the target.

Maidong took a deep breath and turned on the camera.

Three hours later.

Both Tang Yue and Maidong fell silent. Tang Yue sat in the hall, looking at the images on the computer screen, puzzled... How could this be possible? How the hell is this possible? Did that cat evaporate? Such a big cat and such a long dog, how could they just disappear?

After careful searching, Maidong and Tang Yue finally confirmed that the old cat had not overturned under the cliff, in the ditch, or at the bottom of the slope. Tang Yue could not wait to search every pixel of the photo three times. But unfortunately, there was no trace of the old cat under the cliff, and there were no traces of foreign objects in the deep ditch and steep slope. Tang Yue's excitement and enthusiasm turned into cold disappointment.

If even the old cat crossed the cliff and ditch safely, why did it lose contact for no reason? Did it really overturn on the ground?

When did the Martian stray dog ​​gain the attribute of falling on flat ground?

"Tang Yue... maybe Mr. Cat has a problem in other places. Maybe there are still missing places. Should we continue to look for them in other places?" Maidong asked.

Tang Yue didn't say anything. He tore off a piece of blank draft paper, folded it in half and flattened it, and then took out his pen.

"what do you want to do?"

"I want to make a memorial tablet." Tang Yue unscrewed the pen cap.

"What tablet?"

"The tablets of gods and Buddhas."

"Didn't you say that praying to God and praying to Buddha doesn't work? God is dead, and we can only rely on ourselves." Maidong said, "Why do we still need to make memorial tablets?"

"The memorial tablet does not have to be used for worship." Tang Yue wrote a few big words on the white paper, "God damn it."

Then he put the white paper on the table and shouted angrily: "Go to hell, you thief! See you again!" Then he slapped it hard on the floor and stepped on it hard. .

As expected, tablets do not necessarily have to be used for worship.

It can also be used to whip corpses.
