The old cat stared at the computer, on the screen the Eagle spacecraft is just a shapeless particle, it gradually rises along a preset trajectory, two Raptor 3C rocket engines can accelerate the ascent of the lander to the orbiting speed of Mars, that is, about 3.5 kilometers per second, this speed is half lower than the first cosmic velocity of the Earth, so it is easier to launch a spacecraft on Mars than on Earth.

At present, the surface wind speed is basically maintained at about 30 meters per second, and the Eagle spacecraft can maintain a relatively stable connection with the Kunlun station, and the wind speed may be greater in higher places, but the air in higher places is thinner, so the higher it rises, the better the environmental conditions, and the less impact the sandstorm will have on the lander.

The old cat's expression was solemn, and he didn't dare to be careless.

The launch of the Eagle spacecraft is only the first step in a long journey, and there are still thousands of hurdles to overcome.

Even if the launch is successful, they still only have a 9.44% docking success rate, which is less than a tenth of the chance, which is all the vitality of Mai Dong.

The tiny cursor flashes at a frequency of once a second, moving pixel by pixel on the screen, it represents the Eagle spacecraft, and every second the lander calls the Kunlun station, which then responds to locate itself, and so far, the lander is still ascending vertically.

The front of the lander on the computer screen is marked with a dotted line, which is the old cat's predetermined flight path, and the dotted line will soon turn from a vertical ascent to an inclined arc, which means that it will not take long for the Eagle spacecraft to change its attitude.

Whether on Earth or Mars, although the spacecraft are launched vertically, they will quickly turn to an inclined direction after liftoff, which is usually about 60 seconds, in order to enter orbit as soon as possible. The old cat sat in a chair with a pen in his paw and spun around restlessly.

The cursor moved slowly, flashing again and again, and it looked like a turtle crawling.

But in practice, the Eagle spacecraft has tripled its hypersonic speed, with two powerful Raptor 3C engines providing the lander with an acceleration of 17.5 m/s² and placing it into orbit two hundred seconds later.

At this stage, the old cat can only sit and watch, praying in his heart that nothing will go wrong...... A large metal lump weighing tens of tons rampages at a high speed of thousands of kilometers per second, and God can't save it if something goes wrong, and the old cat only hopes that the two engines are obedient enough, and the system computer of the Eagle spacecraft does not have a convulsion.

As long as everything goes according to its plan, then there is hope.

One in ten probability, for its old cat, is enough.

The timer in the lower left corner of the computer screen was beating minute by minute, and the lander had been launched for 50 seconds, and at the moment the lander was at an altitude of more than 20 kilometers above their heads.

In ten seconds, the Eagle will begin to change its pitch angle, from vertical to inclined.

The old cat clenched the pen in his hand.

The acceleration of eighteen meters per second is not a difficult overload to bear, it is less than two Gs, and the overload of fighters ejected from aircraft carriers is more than three Gs, this acceleration is only pediatric for spacecraft, but the old cat still can't help but worry...... After all, this spaceship is too important to be sloppy.

Tang Yue leaned against the porthole, he could no longer see the fire of the lander engine, the moment the Raptor 3C rocket started, it was radiant, but as the lander gradually left the ground, the fire of the engine gradually disappeared in the dark storm.

For some reason, Tang Yue's heart was empty, as if he had just said goodbye to an old friend, and he hadn't even seen the last of this old friend...... When the storm subsided and he went to the Eagle again, he must have seen nothing but a blackened descendant.

The only spaceship in his hand that had the ability to leave Mars was also gone, and from now on, Tang Yue was completely trapped and died on this planet.

Although Tang Yue had never thought of leaving here on the Eagle spaceship, this fact still made him a little panicked.

It's probably a feeling of being cut off.

Tang Yue turned around and walked over to the old cat and sat down on the chair.

"Is this kid okay?"

The old cat nodded slowly, "So far, the little one has been safe all the way...... It has essentially left the atmosphere of Mars, and the sandstorm has completely failed to affect it. ”

The old cat stretched out his paw and poked a small green dot in the upper right corner of the screen, which was flashing regularly.

"This is the Eagle spacecraft is reporting safety, and it will take the initiative to contact the Kunlun station every second to report its speed, altitude, attitude and other status to me, and then the Kunlun station will provide corrections." The old cat said, "It's changing its posture." ”

Tang Yue's gaze fell on the computer screen, and the small cursor of the Eagle spaceship began to turn along the dotted path.

The pitch and angle of attack data displayed on the other side of the screen changes dramatically.

"Very good...... Very good...... Take your time, hold steady, hold steady ......" The old cat chattered, staring intently, it watched the central axis of the Eagle spaceship gradually coincide with the dotted line, and then clapped its hands excitedly, "Beautiful! ”

One-third of the working time of the Raptor 3C engine has passed, and the speed of the lander has increased to 1,200 meters per second, and the old cat does not know when he will lose contact with the Eagle spacecraft, and it hopes to stabilize the lander as much as possible.

"Our delivery van has been successfully turned! What an obedient and good boy! The old cat said, "Next it will go straight to the mooring track!" ”

The Eagle spacecraft is in an elliptical orbit with a perigee of 150 kilometers and an apogee of 350 kilometers, and it will first enter this orbit and then look for opportunities to change orbit and rendezvous with the United Space Station.

The anemometer suddenly gave a warning.

Tang Yue and the old cat were taken aback.

The wind speed began to rise again, rising to 35 meters per second within a few seconds, and the system's computer also gave a prediction, with a striking red line rising like a ferocious cobra and breaking through the 40-meter mark again in 10 minutes.

Now it seems that the gap between the reduced wind speed is indeed only a few minutes, the low pressure area of the cyclone has passed, and the Kunlun station has re-entered the storm-ravaged area.

"Damn it!" The old cat glanced at the numbers on the anemometer and then at the speed of the Eagle spacecraft on the monitoring system, both of which were increasing dramatically.

It didn't expect the wind to pick up so quickly.

The old cat stared at the state of the anemometer and the Eagle spacecraft at the same time, it was very anxious but it couldn't do anything, the weather was force majeure, and the speed of the Eagle spacecraft could not be rushed. If the wind speed continues on this trend, the signals from the Eagle spacecraft will soon be interfered with, and the communication between them will be broken. The old cat only hopes that this moment can be postponed as much as possible.

"Run, boy...... Run......" The old cat stared at the lander on the screen, "run faster!" ”

Tang Yue grabbed its shoulders tightly.

The old cat and the Eagle spacecraft are both in a race against time, the fierce cobra on the anemometer has already caught up, and it is actually the Kunlun Station on the ground that the storm has affected, but Tang Yue and the old cat are both urging the Eagle spacecraft to run fast...... It was as if the snake would catch up and swallow the Eagle ship in one gulp.

A man and a cat shouted while jumping on their feet in Kunlun Station like a nervous disorder:

"Run! Come on! Run a little faster! ”

"Kitty Hawk Run! Come on! Hurry up ......"

In the next second, Tang Yue and the old cat's shouts stopped abruptly, and a pop-up window popped up on the computer screen, with eye-catching scarlet words:

“WARNING:NO SIGNAL！”

The signal was interrupted.
