But just think that after the acceleration ends, 15 decelerations will also be performed in the next time, so that when the spacecraft reaches the range of Mars' gravitational field, the speed will drop to the value range when it departs from the earth.
This is another 15 times of torture. When I think about 15 more times, no one can cheer when I think about it.
Li Linfei was bored thinking about this kind of thing that he spent money to make himself suffer, he seemed like a masochist.
Having said that, although there are 30 tortures, it is not without rewards. The spacecraft Li Linfei and the others are in can also continue to slightly accelerate for a long time like the "Noah".
But the corresponding price is that nearly two hundred days were wasted on the voyage that could not be done.
However, if Li Linfei and the others travel to Mars in the same way as the "Noah" based on the relative distance between the Earth and Mars before departure, it will mean that it will take more than 200 days to reach Mars.
30 times of torture can be exchanged for more than 100 days of precious time, which is worth it no matter what.
The old Americans don't even have the chance to be tortured.
45 minutes later, the front engine on the "Mars Express" started, thousands of lasers and hundreds of thousands of laser beams irradiated on the light sail, and the slowly decelerating spacecraft accelerated again.
The reason why the spacecraft decelerates slightly at this moment is due to the solar wind. The "Mars Express" did not retract the light sails, and the front engines stopped the energy output.
The solar wind will naturally force the spacecraft to slow down with the help of the huge light sail. During this period of time, the third layer of the light sail should be used to obtain energy from the sun, so the multi-layer structure of the light sail cannot be put away.
After the front engine is in operation, part of the thrust generated counteracts the resistance from the solar wind and begins to accelerate forward

2023年10月11日，火星高空轨道，“诺亚号”船上时间：15：36分。“9……8……7……”
A crew member reads the countdown while controlling the "Noah", and the "Orion" spacecraft at the bow of the spacecraft, Skovo and Jackson, are getting ready.
"... 2... 1 Hull separation!" On Wan Lai's silent Mars parking orbit, the "Orion" spacecraft was officially separated from the "Noah", and the "Orion" spacecraft carrying two crew members who landed on the surface of the planet began Cut towards the Martian atmosphere.
The spacecraft entered the Martian atmosphere at a speed of 93 kilometers per hour, and the exterior of the hull quickly became hot and deformed. This is a normal phenomenon, but it is not as serious as the earth.
Because the atmosphere of Mars is thin and the gravity of the planet is not as good as that of the earth, the "Orion" spacecraft enters the atmosphere of Mars at super high speed.
Due to atmospheric friction, the temperature on the outside of the heat shield outside the hull is almost the same as the surface temperature of the sun, reaching more than 1450 degrees Celsius. Fortunately, with the protection of the heat shield, the temperature inside the spacecraft is only about 20 degrees Celsius of normal temperature.
Over time, the velocity of the first stage of the Orion spacecraft dropped thousands of kilometers per hour.
The spacecraft continued to descend, and the height difference became smaller and smaller. At this time, a huge parachute was opened, and the spacecraft further decelerated.At this moment, the reverse thrust nozzle of the "Orion" spacecraft has adjusted its angle, but the speed of the spacecraft's descent is still very fast.
If it hit the surface of the planet, it would also be the result of the shipwreck, and the height difference is getting smaller and smaller, and it has dropped to a three-digit height.
Just when the spacecraft was about to hit the surface of Mars, the three groups of nozzles spurted out tongues of fire in an instant, creating a sky full of dust in the Pezos highlands in an instant, and the reverse thrust continued to offset the speed of the spacecraft.
In the end, the "Orion" spacecraft was only tens of centimeters away from the surface of Mars, and the flames from the three sets of engine nozzles disappeared instantly. Once the engines were turned off, the spacecraft that had lost thrust was pulled by gravity on the spot, and it collided heavily with the surface of Mars. I was motionless.
The two astronauts in the spacecraft felt a relatively strong vibration and then returned to stability.
"Here?" Skovo said suspiciously.
But his teammates did not respond, and he replied: "It should be here!"
The two looked at each other in blank dismay for more than ten seconds, and the next moment they burst out laughing excitedly.
Chapter 180 Nine Martian Creatures
"Here! Here we are!"
"We landed on Mars?"
"Yes, yes! Jackson, we made it to Mars alive! We are the new legends!"
"Haha!!" A burst of excitement passed, and the two astronauts quickly sent the news back to the "Noah" in high-altitude orbit. The entire "Noah" cheered again, and immediately sent it to the earth A text message.
In the "Orion" spacecraft, the two landing astronauts have left the driver's seat and checked the space suits repeatedly to confirm that there is no problem before preparing to leave the cabin.
Scovo Alderaan, who was walking in the forefront, was about to open the hatch, suddenly stopped and turned to look at his partner, asking: "Jackson, will everything I say next be recorded in the history books?" ?”
"Uh...it should be, I think." The partner adjusted a camera in his hand, and when he was about to aim at Skovo, the latter quickly covered it: "Wait a minute, oh damn, where's the line?"
"What line?" Jackson asked suspiciously.
"Nonsense, of course it's a line that will go down in history. No one told me the line and how should I say it?"
Scovo was in a hurry: "God! Did they forget to prepare their lines? Contact the 'Noah' immediately."
"Oh..." Jackson hastily sent out a message, and after a while, he shook his head and said, "No!"
"What? No? Are you sure?"
"I'm sure, and old man, we are consuming oxygen every minute and every second, so don't waste time, play on the spot and say something casually, it will be recorded in the history books anyway, of course, the most important thing What's more, I don't need to take the blame for your stupid words, hehe."
"Oh no, God bless, or that old guy Charles will kill me when I go back."
Jackson shook his head helplessly, then pointed the camera at his partner. Skovo took a deep breath, and finally opened the hatch.
At this moment, it is daytime on the Pezos Heights, and the face of Mars is immediately in sight.
This is a world of iron oxide, where the earth is red. In the video, Skovo carefully walks down the 7 steps step by step while holding the outer bar.
When he stepped on the penultimate rung of the ladder.With a light jump, the whole person jumped on the red ground. Jackson carried the camera and recorded this historic moment with his jerky shooting techniques. When Skovo Alderaan took the first step At that time, a footprint with historical significance appeared.
Finally, the camera pointed at Skovo Alderaan, who planted an American flag on the ground, and then looked directly at the camera lens: "This is Mars, here we are. I will be the first Man who left footprints on Mars, first man who planted a flag on Mars, first man who touched the air of Mars."
"The first to walk, run, sit, and eat on Mars...no matter what I do next, it will be No.1 in history. Armstrong, I officially declare that I surpass you. To all human beings, the pioneers and travels are legends!"
Against the backdrop of Mars, Scovo stared straight into the camera and freezes as Jackson puts away the camera and returns to the spacecraft for backup in what will go down as one of the most significant footage in human history.
Scovo, who stood on the land of Mars for the first time, looked around for a week, his eyes wandering over the skyline of Mars and the entire land.
Walking around the spaceship, the view of the Pezos Heights comes into view. The front left is a small highland with a slope angle of more than 30 degrees.
He quickly saw several large caves on the slope, with different diameters, but they were all very large. He knew that there was originally a volcano in the Pezos Highlands, but the Pezos volcano had stopped 2 million years ago. activity.
Those caves should be the former magma tunnel, so he guessed in his heart.
"This is 'Noah', call 'Orion'!"
"I'm Skovo, received."
"The first batch of materials will be released in 40 minutes, about 11 kilometers away from the landing point, the approximate coordinates..."
"Got it, Jackson, I'm going to get the Mars rover off the spaceship, and I'm busy next time."
As Scovo said, he walked towards the spaceship, and within a few steps, something kicked him suddenly and stopped him. He looked down at his left foot slightly, and swept the red dust with his foot.
A snow-white smooth object appeared in the field of vision, which was very eye-catching on the monotonous red soil.
