Phobos is so small, it's an irregular celestial body 27×22×18 kilometers away, its gravitational pull is pitifully small, and even if you stand on Phobos and jump hard, you can fly out of its gravitational pull into space!

Its gravitational pull was of little use to the engineering boats, and the two engineering boats swaggered towards the Phobos, and the engines used only a small amount of power to stabilize their attitude, and then the two boats split into two ways and fell to the sides of the Phobos.

The engineering boat did not land on the surface of Phobos, but flew flat at low speed on the ground of Phobos, and various instruments on the boat continuously collected data along the way and recorded them in the equipment one by one.

Ye Han probed his brain curiously, staring curiously at Xu Moliang and the driver.

Xu Moliang inadvertently turned around, and happened to see Ye Han with his neck crooked, and couldn't help but be stunned: "Captain Ye? You're ......"

Ye Han straightened his head and smiled generously: "I'm a little curious, I want to see how you do the survey." He had learned a lot about astronomy, but this was the first time he had encountered an extraterrestrial object.

Xu Moliang suddenly realized: "Hey, I said, it's actually nothing, it's just to use remote sensing technology to find out, first take a preliminary situation and delineate a few key areas, and then go to the ground to investigate." ”

"Oh!" Ye Han seemed to be stunned, but in fact, he still didn't understand much.

The survey continued, and the two engineering boats spent a perfect time, sweeping the surface of Phobos back and forth, even the most remote corners, until they got the three-dimensional model of Phobos to complete the preliminary survey.

Xu Moliang called up the 3D model from the system and carefully studied the data of Phobos.

Ye Han also floated over curiously, staring at the excitement with wide eyes.

I don't know if I don't know it, but I'm shocked when I see it, the geological situation of the small Phobos is quite complicated, and you can see solid rocks, scattered water ice and loose gravel from the model.

Xu Moliang was engrossed in drawing an arc in the corner of the model as a marker, and then added another one after the arc.

In this way, Xu Moliangdong stroked west, and it didn't take long for a good model to make him draw messily, with crooked lines everywhere, like being scratched by a cat.

Ye Han couldn't understand it, and couldn't help asking, "XCMG, what is this for?" ”

"I'll be exploring along these lines for a while...... Wow, why are you so close to me! Xu Moliang leaned back in disgust and kept a safe distance from Ye Han.

Ye Han almost sprayed a mouthful of old blood on the screen: "What kind of expression do you have?" "He said in his heart that Lao Tzu didn't think you were sloppy, you are a wicked person who sues first!

Xu Moliang looked serious: "I'm a straight man!" ”

Ye Han was angry: "I'm not bent!" ”

"Then why are you so close, keep a safe distance!" Xu Moliang crossed his arms, indicating that he was forbidden to approach.

Ye Han's whole person was not good, so he simply retreated neatly, and said in his heart, who sent the second goods? God sent me to play with this, right?

The soldiers who saw this scene snickered.

Xu Moliang devoted himself to drawing the line again, and after a while, he finished the last stroke, and let out a sigh: "Captain Ye! ”

"What for?" Ye Han didn't mean to move forward at all.

"This!" Xu Moliang pointed to the three-dimensional model of Phobos, "I have drawn lines on the model, and each point is marked, and I will trouble you and your troops for a while...... Uh, punch sampling in order! ”

"What about you?" Ye Han asked in surprise.

"Deimos, of course." Xu Moliang said as a matter of course.

"Wait a minute, what the hell is going on with these lines?" Ye Han pointed to the three-dimensional model and asked.

"This one, it's easy!" Xu Moliang also pointed to the model, "See, there's a hill here." ”

Ye Han nodded: "See, then what?" "The hill on the model has three lines drawn halfway up to cut off the peak.

"Now we only know what's going on on the surface, but I need to know what's going on deep underground." Saying that, Xu Moliang pointed to the first line, "This mountain is particularly suitable for blasting, if the ground is full of stones, then make holes and blast in this line; If it's gravel or water ice, blast it on the second line; No matter which line is blown up, there are one million tons of hills intercepted, and this quality is the most convenient to smash Europa. ”

Only then did Ye Han understand Xu Moliang's intention of drawing so many lines, and if he looked carefully, all the protrusions on Huobos had been marked by Xu Moliang, and they were all three lines.

But he suddenly saw a circle drawn in the crater in the middle of Phobos: "What's going on with this?" ”

Xu Moliang saw the place Ye Han pointed at clearly, and then said unhurriedly: "There is very likely to be a meteorite here, according to the area of the crater, if the meteorite is still at the bottom of the pit, it must be in this circle!" ”

Is that okay too? Ye Han couldn't believe his ears.

Xu Moliang waved his hand impatiently: "Okay, you don't need to know why, you just need to know what to do, and take samples according to the marks drawn on the map." ”

"Okay, you say!" Ye Han had a constipated expression on his face.

It's not that he has a small belly, but Xu Moliang's attitude is really angry, why didn't he find out that he was such a person when they first met?

But it's not too late to know now, Ye Han immediately asked, "What do I use to hit my eyes?" ”

"There is a drill bit drilling rig behind the engineering boat, so you don't need to dig too deep, just take a sample at twenty or thirty meters." Xu Moliang said.

"Okay, got it." Ye Han agreed, immediately took over the No. 1 boat, and flew to the nearest line.

Ye Han didn't know the situation of Phobos, and he didn't know where the lines on the model were, but fortunately, the pilot was more familiar with the situation, and soon flew the engineering boat to a desolate hill.

The engineering boat slowly approached the hill, and it was leaning over, and a few ropes were suddenly drawn around the boat, and the steel anchor on the cable head was inserted deep into the ground, and then the engineering boat tightened the cable, pulling the engineering boat towards the hill, and soon fixed the engineering boat on the side of the hill, almost vertical on the mountain wall.

The driver started the rig, and the rig placed behind the boat was automatically erected, and the drill bit was pressed against the ground, then spun rapidly, and it didn't take long for it to drill into the ground.

Ye Han didn't feel anything, Xu Moliang's brows furrowed deeply: "No, the drill speed is too fast!" ”

Ye Han was very puzzled: "Isn't it fast?" ”

"Of course it's not good, the faster you drill, the lower the density, do you understand?"

"I understand it now...... What is the density now? Ye Han saw that the drill bit had gone seven or eight meters deep into the ground.

"It's very low, it's basically water ice." Xu Moliang's eyes were stagnant, and his voice was also very low, "This kind of density can't be used at all...... Forget it, it's all hit, go ahead, drill deeper for me, and take a few more samples! ”
