Tang Yue was stunned for a few seconds, and his nose couldn't help but feel a little sour.

This is the last Eagle spaceship, the earth has disappeared, every part of the spacecraft will become a unique product in the universe, a relic of human civilization, the sentence "Welcome to Eagle Lander" on the screen is the blessings and greetings of those old people and friends who disappeared to him, Tang Yue never thought that that farewell at that time could become a permanent secret.

Tang Yue sat down on the commander's chair, he had always wanted to sit on this chair, but the captain Wang didn't allow it every time, and the king of sassy words took his broken chair very seriously.

Now Tang Yue can sit as much as he wants, and no one has come forward to stop him, and the entire Orion No. 1 spaceship and the scientific expedition team have disappeared.

The indicator light on the main console in front of him is flashing, dense code rolls through the screen, the computer of the Eagle spacecraft is booting self-check, the computer on the Eagle spacecraft is a very powerful thing, Lao Wang said that it can even be used to play red alert and Warcraft, it is not easy for the computer of aerospace engineering application level to do this, the main frequency of the computer on the Apollo spacecraft was only 2M Hz, plus a 2KB RAM and a 36KB ROM, not even a song can be saved.

The lander's take-off, landing, rendezvous and docking can all be done automatically, and the engineers on Earth have already set the route for it, and these tens of thousands of codes are stored in the computer of the Eagle spacecraft, and the crew only needs to move their fingers, press a few buttons, and then shout "Go, you-", and the Eagle spacecraft can take them away from Mars.

But just in case, the designers still left a spare manual control system for the lander, in case Tang Yue and they were really unlucky to the point of farting and smashing their heels, and the automatic docking system unfortunately failed, then the commander stepped forward and showed his ability and skills as an elite astronaut, manually controlling the lander to dock with the United Space Station.

In the past nearly 100 years, the pioneers of aerospace in human history have done this, and when the ability of computers is not enough to control everything and grasp the overall situation, the astronauts of the United States and Mao Zi are dancing on the wire and the tip of the knife with their own eyes and fingers, relying on excellent psychological quality and technology.

But Tang Yue will not use this system, and there are only two people in the expedition team who can use the manual docking system.

One is to command the Elder King.

Lao Wang was born as a test pilot of the Chinese Air Force, with the rank of colonel, flew thousands of hours of fighter planes, and then was selected to enter the astronaut center, as the commander of this Mars mission, he is the most senior and experienced astronaut in the team, and he is awesome and coaxing.

The other is old soup.

Old Soup is an American, his full name is Howard Thompson.

Lao Tang, the team's second professional astronaut, spent more than 320 days on the International Space Station, often taking care of the Soyuz-Progress spacecraft's docking missions, and he also uses this manual docking system.

Tang Yue's identity is a mechanical and electrical engineer, and his mission is to be responsible for the maintenance of Kunlun Station and the Mars rover, and Mai Dong's identity is a botanist, who came with a lot of scientific research tasks, and they have never touched the control stick of an aircraft in their lives.

The screen on the main console slowly dimmed, and after a few seconds, it lit up again.

The NASA logo flashed out, a bit like a Windows boot screen.

The self-test is complete.

Tang Yue took out the maintenance manual as thick as an Oxford dictionary from his bag, it was indeed a hassle to check the Eagle spaceship, and there were more than 13,000 items from beginning to end.

"Old cat, you have to read all the rules and regulations on this?" Tang Yue lowered his head and shouted at the hatch under his feet.

"That's right!" The old cat's voice came from below, "I have to check everything!" ”

"I'm ...... Do you know how much content there is? ”

"Six major departments, eighteen small departments, a total of thirteen thousand four hundred and sixteen articles, and eleven appendices." The old cat replied, "It's the third day, we need to launch the Eagle spacecraft as soon as possible, you better hurry!" ”

"You want me to do it all?" Tang Yue glared, "This is impossible." ”

"Who was it at that time?" The old cat snorted, "If you can't handle it, then I have no opinion, but that little girl on the space station is dead." ”

"You ......" Tang Yue choked, "Okay, count you ruthless." ”

The old cat stood in the cargo hold with an ultrasonic flaw detector in his paws.

Ultrasonic flaw detector is a fairly commonly used detection equipment in engineering, ultrasonic waves can penetrate deep into the workpiece, to check the invisible cracks, looseness, porosity, once the ultrasonic contact with the damage section, then it will be reflected back, showing abnormal waveforms on the oscilloscope.

The old cat holds the display terminal in one hand and the probe in the other, it holds the probe close to the inner wall of the spaceship, and its eyes are staring at the display on the terminal, and the waveform folds very regularly, like someone's heartbeat.

The cargo hold of the Eagle spacecraft is a cylinder, more than a meter high, made of a large complete sheet of aluminum alloy rolled up, which can carry up to three tons of cargo.

It stands to reason that there should be no problems with the main structure of the lander, as early as before the launch, the people on the earth have carried out a very thorough inspection of it to ensure that it is foolproof, but the old cat is still not at ease, even if the lander has been checked on the earth, it was more than a year ago, the environmental conditions in space and Mars are harsh, the temperature difference between day and night is large, and the re-entry into the atmosphere has undergone high temperature scorching and large overload reversal, these extreme environments are a great test for any material.

Metal fatigue is inevitable somewhere, or a rubber seal freezes and shatters, and these scars, which are barely visible to the naked eye, can quickly develop and spread under conditions of high acceleration and high overload, and eventually cause fatal structural damage.

The Eagle spacecraft would most likely have to repeat the mistakes of the Challenger space shuttle and turn into an oversized Sky Monkey, turning all the supplies and Tang Yue's hopes into ashes over Mars with a bang.

The interior lining of the cargo compartment is a layer of smooth and hard polyimide material, and the white inner wall is printed with the blue logo of Boeing.

The cargo compartment of the Eagle spacecraft is manufactured by Boeing, and the control system of the lander is the product of the old rival Lockheed Martin, and the different parts of the spacecraft are from different companies and manufacturers.

Boeing, Lockheed Martin, Northrop Grumman, NASA, CNSA, China Aerospace Science and Technology Corporation, China Aerospace Science and Industry Corporation, Apple, SAMSUNG, Central Institute of Fluidics, ESA, Rolls-Royce Group, JPL, etc., these world-famous institutions and enterprises are usually competitors who do not look at each other, but on the Eagle spacecraft, their logos coexist side by side.

The Mars landing program is the largest space project in the history of mankind, and its scale far exceeds that of the Apollo moon landing of that year, and the old space powers such as China, the United States, Russia, Britain, France, Japan, and Germany have worked together to cooperate, because the difficulty and cost are no longer affordable by any single country, and the US imperialists cannot afford it with such wealth.

Chinese representative: Whoever has money will invest more, don't you have any opinion?

Russian representative: yes! Let me first say that my family is poor, only technology, not money! (AK47 under the table and looking around) Anyone who has an opinion can put it forward.

British representative: I will vote as much as France.

French representative: I will vote as much as Germany.

German representative: I will vote as much as the UK will vote.

Representative of Japan: That...... That's not enough money.

China Representative: Who is the richest? First of all, I solemnly declare that China is a developing country and is in the initial stage of socialism and will remain so for a long time......

British, French, and German European representatives: (whispered bb) US imperialism.

Russian representative (loud bb): US imperialism!

The representative of the US imperialist slapped the table angrily: still let me invest money? Can I build my aircraft carrier?

From the Orion spacecraft to the lander to the Kunlun station, every step is the product of the cooperation of all human beings, and is the crystallization of true human wisdom.

The global human race has taken this step together, leaving a shallow footprint on this planet of more than 60 million kilometers.
