Ye Han left, but Lin Yi couldn't go, 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 were ready-made, and it didn't take long for Lin Yi to get the calculation results with the assistance of the control system.

Lin Yi entered the data into the flight control system, solemnly clicked to execute, the engine of the Yushan that had been silent for a long time immediately started, and the spacecraft began to adjust its attitude, changing from normal flight to a deceleration mode with its head facing backwards and its buttocks forward.

Most of today's warship engines use the wing-mounted scheme of transport aircraft, and there is no need to adjust the hull attitude when decelerating, as long as the engine is deflected 180 degrees, it can enter the deceleration mode.

However, those are the main warships, and the Yushan is a landing ship, and the special mission purpose makes the Yushan adopt a more traditional layout design, and when slowing down, it must be the same as the old warship.

Fortunately, the Yushan now only has the orbital cabin, the ship is short and thick, and it is more troublesome for ordinary warships to turn around, but it is very simple for the Yushan.

A few minutes later, the ship's attitude was adjusted, and a blazing white light suddenly burst out from the main engine, and the battleship continued to slow down in the explosion of the engine, and soon broke away from the Third Fleet.

The speed of the Third Fleet is too fast, and if you fly to Mars at this speed, you will only pass near Mars, and there will be no chance to fly around Mars at all.

The deceleration of Yushan lasted for five days, and the voyage of the original two-day voyage was extended to five days, and when Yushan arrived at Mars, it cut into orbit from the front and finally reduced its speed to less than five kilometers per second.

Mars has an escape velocity of 5.02 kilometers per second, and it is impossible to orbit Mars without reducing its velocity below this speed.

There were still two days before the arrival of the engineering ship, Ye Han had already waited impatiently, ran to the bridge and Lin Yi used binoculars to look for the engineering ship everywhere, and it only took two minutes for the two of them to find a small bright spot on the side of the sun.

Lin Yi immediately put the image of the engineering ship on the main screen, and the two of them immediately saw the engine of the engineering ship rushing forward, and the white light in the engine was constantly flickering like a landscape light.

Ye Han tugged at the corners of his mouth: "Are they slowing down, Lin Yi, what is the distance now?" ”

"More than 900,000 kilometers, less than a million."

"Give me a communication channel!"

"What for?" Lin Yi asked curiously as he complied.

Ye Han showed a smile: "Ask a few questions." ”

The communication system was activated, Ye Han adjusted the headset and said: "Luzhou Luzhou, Yushan calls, please answer if you receive it!" ”

There was silence on the radio for more than ten seconds, and finally received a reply with a murmur: "Yushan Yushan, I am Luzhou, please speak!" ”

The two people on the bridge looked at each other and smiled, and Ye Han continued: "Luzhou, our department is 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 you need them?" ”

The task of the engineering ship is to survey the situation of the two satellites, even if the two satellites are thoroughly studied, they have to wait for the super engine in the orbital factory to come off the assembly line, so the task of the engineering ship is not tight, there is no need to invest so much manpower at all, as long as the situation is thoroughly understood before the super engine arrives.

"It's a bit much...... About a dozen people. ”

"Fifteen, then." Ye Han clapped, "It's not enough to say more." ”

"Yes."

"What else do I need to prepare?" Ye Han asked again.

"Nothing is needed...... Well, I'll give you a copy of the orbit data, you just took advantage of the two days to change the orbit, and you have to have a meeting to coordinate the work after the convergence. ”

"No problem, always waiting." Ye Han said.

At the end of the communication, Ye Han let out a sigh of relief, and Lin Yi exaggeratedly wiped a handful of non-existent sweat: "My mother, I'm tired and panicked when I hear it." ”

"You're not tired when I'm tired?" Ye Han glanced at Lin Yi, "Okay, you continue to watch, I'll pick someone." ”

"Pick whom?" Lin Yi instinctively asked.

Ye Han smiled: "Of course it's pleasing to the eye!" ”

"Will you bring Gong Lei with you? I've been staring at it alone for the past few days, and I can't keep an eye on it. ”

"Okay!" Ye Han agreed, turned around and floated out the door.

After a while, more than a dozen marines and Gong Lei lifted their hibernation together.

Ye Han waited patiently, and only after everyone recovered did Ye Han bring the team into the conference room and convey the orders of the Mars plan.

Before the situation was finished, there was an uproar in the conference room.

Ye Han didn't care so much, after ordering everyone to shut up, he continued to read the order until he spit out the last word: "The day after tomorrow, the engineering ship arrives, one of you counts one, give me a stop, if you don't understand anything, read the plan yourself, and break the meeting!" ”

The meeting was short and efficient, and in the next two days, Lin Yi and Gong Lei were busy correcting their orbits, because they entered the orbit in the wrong direction, and flew away from Mars and circled around to re-enter the orbit from the opposite direction.

Ye Han led the soldiers to overhaul the equipment to prevent unexpected failures during the mission.

On September 19, 2027, the engineering ship Luzhou arrived on Mars and successfully entered orbit to orbit Mars.

Before, because the distance was too far, Ye Han never saw the appearance of the Luzhou clearly, and it was not until the Luzhou entered orbit that he saw the true face of the Luzhou Mountain.

Ye Han could see at a glance that the Luzhou was a modified ship, but the modification was too thorough, and the outer shell of the spaceship was full of construction machinery with different functions, and these mechanical equipment were fixed on the surface of the spaceship, and many of the equipment could not even be named.

The weapons systems that were supposed to cover the entire ship were basically eliminated, and only a few rapid-fire guns against asteroids were left hidden among the equipment of the forest.

After Luzhou entered orbit, it immediately established communication with Yushan, on the one hand, asking Yushan to approach, and on the other hand, inviting Ye Han to participate in a video conference.

A few minutes later, the video conference between the two ships was held as scheduled, and Ye Han saw a sloppy man in a spacesuit, about thirty years old, with a beard on the screen.

is obviously wearing a clean spacesuit, but it can make people feel a sloppy place coming towards him, this person is simply sloppy to the bones, revealing such a sloppy energy from the inside out.

The sloppy man took out a photo of an asteroid very bluntly, pointed to the photo and said: "This is Phobos, our first target, we need to carry out the necessary exploration on Phobos, figure out the geology of Phobos, and plan to drill wells and samples here, 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, fifteen is not enough and there are more than twenty hibernating." Ye Han said.
