Ye Han left, but Lin Yi could not leave. He immediately called up the flight data of the spacecraft and the operation data of Mars and began to calculate the new orbit of the spacecraft.
All the data was ready-made. After a while, Lin Yi got the calculation results with the help of the control system.
Lin Yi entered the data into the flight control system and solemnly clicked "Execute". The Yushan's long-dormant engine immediately started, and the spacecraft began to adjust its attitude, switching from normal flight to a deceleration mode with its head facing back and its butt forward.
Most of today's battleship engines adopt the wing-mounted solution of transport aircraft. There is no need to adjust the attitude of the ship body when decelerating. You only need to deflect the engine 180 degrees to enter the deceleration mode.
However, those are all main battleships, and the Yushan is a landing ship. The special mission purpose requires the Yushan to adopt a more traditional layout design. When decelerating, it must be like an old battleship.
Fortunately, the Yushan only has its orbital cabin left, and the ship is short and thick. Turning around would be troublesome for ordinary battleships, but it is very simple for the Yushan.
A few minutes later, the attitude of the spacecraft was adjusted, and a blazing white light suddenly burst out from the main engine. The battleship continued to slow down amidst the explosion of the engine, and soon separated from the Third Fleet.
The speed of the Third Fleet is too fast. If it flies to Mars at this speed, it will just pass by Mars and there will be no chance of orbiting Mars.
The Yushan's deceleration lasted for five days. The originally two-day voyage was extended to five days. When the Yushan arrived at Mars, it cut into orbit from the front, finally reducing its speed to less than five kilometers per second.
The escape velocity of Mars is 5.02 kilometers per second. If the speed is not reduced below this speed, it will be impossible to fly around Mars.
There were still two days before the arrival of the engineering ship. Ye Han was already impatient with waiting. He ran to the bridge and Lin Yi used binoculars to look for the engineering ship. It only took two minutes for the two of them to find a small spot on the side of the sun.
Highlights.
Lin Yi immediately put the image of the engineering ship on the home screen, and the two immediately saw the engine of the engineering ship rushing forward, and the white light in the engine flashed like a landscape light.
Ye Han twitched his lips: "They are slowing down, Lin Yi, what is the distance now?"
"More than 900,000 kilometers, less than one million."
"Give me a communication channel!"
"What are you doing?" Lin Yi asked curiously while obeying the instructions.
Ye Han showed a smile: "Ask a few questions."
The communication system started, Ye Han adjusted the headset and said: "Luzhou, Luzhou, Yushan number is calling, please answer when you receive it!"
The radio was silent for more than ten seconds, and finally received a reply with noise: "Yushan Yushan, this is Luzhou, please speak!"
The two people on the bridge looked at each other and smiled, and Ye Han continued: "Luzhou, our department has been ordered to assist your ship in carrying out the survey mission. How many people are needed for the mission?"
More than ten seconds later: “The more, the merrier!”
"Impossible!" Ye Han replied without thinking, "I have forty or fifty people here, are you sure we need them all?"
The mission of the engineering ship is to survey the situation of the two satellites. Even if both satellites are thoroughly studied, they still have to wait for the super engine in the orbital factory to come off the assembly line. Therefore, the mission of the engineering ship is not urgent, and there is no need to invest so much.
With more manpower, we just need to figure out the situation before the super engine arrives.
"It's quite a lot... about ten people."
"Then fifteen." Ye Han agreed, "If it's not enough, let's talk about it."
"Can."
"What else do you need me to prepare?" Ye Han asked again.
"Nothing is needed... Well, I will give you a piece of orbit data later. You can take advantage of these two days to change the orbit. Also, after the rendezvous, we must hold a meeting to coordinate the work."
"No problem, I'm always waiting for you." Ye Han said.
When the communication ended, Ye Han let out a long breath, and Lin Yi exaggeratedly wiped away the non-existent sweat: "Oh my god, I'm so tired just listening to it."
"You think I'm not tired?" Ye Han glanced sideways at Lin Yi, "Okay, you can continue watching, I'll choose someone."
"Who to pick?" Lin Yi asked instinctively.
Ye Han chuckled: "Of course I am picky!"
"Can I take Gong Lei with me? I'm the only one keeping an eye on him these days. I really can't keep an eye on him anymore."
"Okay!" Ye Han agreed, turned around and floated out the door.
After a while, a dozen marines and Gong Lei came out of hibernation together.
Ye Han waited patiently until everyone recovered, then Ye Han brought the team into the conference room and conveyed the order of the Mars Project.
Before the situation was finished, the conference room was in an uproar.
Ye Han didn't care so much. After ordering everyone to shut up, he continued to read out the order until he finished the last word and said: "The engineering ship will arrive the day after tomorrow. Each one of you, please stop for a moment. Is there anything you don't understand?"
Go read the plan yourself and call it a night!"
The meeting was short and efficient. In the next two days, Lin Yi and Gong Lei were busy correcting the orbit. Because the orbit was in the wrong direction, they even flew away from Mars and circled around to re-enter orbit in the opposite direction.
Ye Han took the soldiers to inspect their equipment to prevent unexpected malfunctions during missions.
On September 19, 2027, the engineering ship Luzhou arrived at Mars and successfully entered orbit to orbit Mars.
Because the distance was too far, Ye Han never saw the appearance of the Luzhou clearly. It was not until the Luzhou entered orbit that he saw the true face of the Luzhou.
Ye Han could tell at a glance that the Luzhou was a modified ship, but the modification was too thorough. The outer shell of the spacecraft was full of engineering machinery with different functions. These mechanical equipment were fixed on the surface of the spacecraft. Many of the equipment could not even be named.
.
Basically all the weapon systems that should have covered the entire ship were cancelled, leaving only a few rapid-fire cannons for dealing with asteroids hidden among the various equipment.
After the Luzhou entered orbit, it immediately established communication with the Yushan. On the one hand, it asked the Yushan to approach, and on the other hand, it invited Ye Han to participate in the video conference.
A few minutes later, the video conference between the two ships was held as scheduled. Ye Han saw a scruffy man in his thirties with a beard wearing a spacesuit on the screen.
Even though he was wearing a clean space suit, he could still feel a sense of sloppiness coming towards him. This man was simply sloppy to the core, and he exuded such a sloppy look from the inside out.
The sloppy man took out a photo of an asteroid very bluntly, pointed at the photo and said: "This is Phobos, our first target. We need to conduct necessary exploration on Phobos to understand the structure of Phobos."
Regarding the geological conditions, we plan to drill wells and take samples here and here... Captain Ye, we have brought all the equipment needed for exploration, but we are short of manpower and need your full assistance."
"No problem, if fifteen are not enough, there will be more than twenty hibernating ones." Ye Han said.
