Tang Yue wore Mingguang armor, opened the hatch of the airlock room, and stood the antenna on the ground against the strong wind.

"The antenna is deployed." Tang Yue reported in a deep voice.

"Start retrieving signals." The old cat's voice sounded immediately, it sat in front of the workbench, all the computer screens in front of it were lit, the Kunlun station at the moment is like a monitoring center, the system computer here is the latest HP workstation, Mars mission special edition, powerful, is a good hand at processing data.

The Eagle spacecraft lost contact one minute after launch, apparently due to the weather, and the radio waves were barely able to break through the interference when the Kunlun station was in the low-pressure area of the storm, but when the sand and dust carrying a huge amount of charge re-covered the research station, the communication power of the Eagle spacecraft was not enough to suppress the ambient noise.

The vertical take-off phase of the lander has ended, and the vertical lift-off can break through the troposphere, the densest part of the atmosphere, at an altitude of about 20 kilometers, beyond which the Eagle spacecraft will begin to change direction.

The old cat forces himself to keep his composure, but at this time anyone can get nervous.

In the space launch mission, the loss of contact is the most frightening thing, tens of millions of kilometers away, electromagnetic waves at the speed of light also have to run for several minutes, in the vast and boundless dark deep space, if you don't take the initiative to send a signal, then no one can find you at all, the invisible and intangible, extremely fragile communication channel, is the only kite line between the spacecraft and the ground, so sometimes the loss of contact, is equivalent to a complete disappearance.

The long silence in the communication channel is like death, in the past nearly 100 years of human space history, such silence has appeared many times, everyone in front of the communication system has a tight heartstrings, but not every silence will be followed by "I am out of the cabin, feeling good".

The Kunlun station is still retrieving signals.

Tang Yue acted as the human servo mechanism of the antenna, and he slowly adjusted the direction of the antenna.

Minutes and seconds passed.

The second minute after the launch of the lander is about to pass, and according to the prediction of the Kunlun station system, if nothing goes wrong, the speed of the lander has increased to two kilometers per second, which is equivalent to six times the hypersonic speed, and the altitude should also reach one hundred and thirty kilometers.

But hell, the old cat can't contact the lander at all.

Without Kunlun standing down and watching, God knows what the bear child of the Eagle spaceship would have done.

In case the computer of the Eagle spacecraft smoked and felt that it was too boring to take off according to the preset orbit and not reflect its strong power, it decided to make a 360-degree turn for three and a half weeks......

The consequences are unimaginable.

Signal ...... Signal ...... Signal! The old cat gritted his teeth, damn it, give me some signal! The real-time measurement data on the computer was still a minute ago, and these parameters had not been updated for a minute.

"Old cat, is there any news?" Tang Yue asked.

"Nope."

Tang Yue sighed, "Sure enough, children are like this, they left the house when they were raised, and when they reached a distant place where their parents couldn't go, they didn't reply to a letter for a long time." ”

The old cat was stunned, listening to Tang Yue's tone, it made him seem as if he had raised a child, and there was an inexplicable faint melancholy in his voice.

"Take me, for example."

The old cat was stunned, and then realized that Tang Yue was talking about himself.

"I was watching the Eagle launch and it gave me this feeling...... The so-called father-daughter-mother-son game just means that your fate with it is to constantly watch its back drift away in this life and this life. Tang Yue began to change Long Yingtai's sentence, "I stood in front of the door of Kunlun Station, watching it gradually disappear to the top of the atmosphere, and it silently told me with its back: There is no need to chase. ”

"Chasing? Can you catch up? The old cat shook his head, "If you have the ability, you can chase one for me to see." ”

Since learning that the earth has disappeared, Tang Yue has become more and more melancholy poetic, and he has nothing to do with a few puzzling sentences, which makes the old cat very worried that this person will go to a rail or something if he can't think about it one day.

"Old cat, you've been on Mars for so many years and haven't been back to Earth, haven't you ever felt homesick?" Tang Yue then asked, "For example, like "Homesickness" in the afterglow...... When I grow up, nostalgia is a small spaceship, I am on this side, and the earth is on that side......"

"Homesickness? What am I missing? Miss the assembly line in the factory? ”

Sometimes the old cat still admires Tang Yue very much.

Although Tang Yue seems to have a little sad temperament, in fact, he is not the kind of person who is really delicate and sensitive, a real poet will probably choose to commit suicide the moment the earth disappears, and be martyred for hundreds of millions of living beings, and a little more performance art may fill the Kunlun Station with pure oxygen, and then set a fire and raise his head and shout: "I am the king of kings!" Meritorious deeds of the world, dare to convince the gods! ”

But Tang Yue didn't have the slightest idea of this, he should eat and sleep, and he wouldn't shout Shelley's poems to see Marx, the nerves of this thing are far beyond the imagination of the old cat, the old cat glanced at the anemometer, and now the wind speed outside is thirty-eight meters per second, and even the roof can fly off the roof on the earth.

But Tang Yue was talking to it about what the child would not come back when he grew up and the nostalgia in the afterglow.

What do you think is emotional delicacy?

Or is there something wrong with the brain?

The one hundred and fifty seconds after the launch of the lander.

The old cat still can't get in touch with the Eagle ship.

According to the normal launch procedure, the lander will enter the parking orbit two hundred seconds after launch, and at the same time abandon the first stage of the rocket, which is the first step into orbit, from launch to rendezvous and docking, the Eagle spacecraft needs to go through three steps, the first of which is to enter the parking orbit.

The perigee of the moored orbit is 150 km, and the apogee is 350 km, which is a slightly flattened ellipse.

The Eagle spacecraft will orbit in a grounded orbit for the right moment, and when the time comes, it will make its first acceleration when it reaches apogee, leaving the grounded orbit and entering a parabolic transfer orbit.

If the situation is worse, the orbit altitude is too low, and the lander may even re-enter the atmosphere and burn up.

The old cat looked at the timer.

One hundred and sixty seconds after the launch of the lander, it was at an altitude of two hundred and twenty kilometers above the ground.

There are still forty seconds left before the first stage of the rocket burns out and disengages.

"Turn the antenna to the east! About 30 degrees! The old cat shouted.

"Adjusting!" Tang Yue slowly turned the antenna, "How's the situation with that kid?" ”

"I don't know what the situation is...... replied the old cat, "you better pray that it will make it into orbit, or your child will probably die outside!" ”

One hundred and seventy seconds after the launch of the lander, it was at an altitude of two hundred and fifty kilometers above the ground.

There are thirty seconds left before the first-stage rocket detaches.
