Eight Hundred and Sixty-Seven Samples

Phobos is really too small, it is an irregular celestial body of 27×22×18 kilometers, its gravitational force is pitifully small, even standing on Phobos and jumping vigorously, it can escape its gravity and fly into space!

Its gravity is basically useless to the engineering boats. The two engineering boats swaggered towards Phobos. The engines stabilized their posture with only a small power. Then the two boats split into two ways and landed on Phobos respectively. on both sides.

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

Ye Han poked his head curiously, staring at Xu Morliang and the driver curiously.

Xu Morliang inadvertently turned his head and saw Ye Han with his neck tilted. He couldn't help being stunned: "Captain Ye? You are..."

Ye Han straightened his head, smiled openly and said, "I'm a little curious, and I want to see how you do surveying." He has learned a lot about astronomy, but this is the first time he has encountered extraterrestrial celestial bodies.

Xu Moliang suddenly realized: "Hey, I said, it's actually nothing, just use remote sensing technology to find out the bottom line, first use the preliminary situation to draw a few key areas, and then conduct a detailed investigation."

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

The survey continued. It took the two engineering boats a time to scan the surface of Phobos back and forth, even the most remote corners. They did not complete the preliminary survey until they got the 3D model of Phobos.

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

Ye Han also floated over curiously, watching the excitement with his eyes wide open.

I don’t know if I don’t see it, but I was shocked when I saw it. The geological situation of the small Phobos is quite complicated. From the model, we can see solid rock, scattered water ice and loose gravel.

Concentrating on it, Xu Morliang drew an arc at the corner of the model as a mark, and then added another one behind the arc.

In this way, Xu Moliang made one stroke after another, and the good model was quickly messed up by him, with crooked lines everywhere, as if being scratched by a cat.

Ye Han couldn't understand, and couldn't help asking: "Xu Gong, what is this for?"

"I'll be doing surveys based on these lines in a while... Hey, why are you so close to me!" Xu Morian leaned back in disgust, keeping a safe distance from Ye Han.

Ye Han almost spat blood on the screen: "What's your expression?" He said in his heart that I don't think you're sloppy yet, you, his grandma, is a villain and sue first!

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

Ye Han was furious: "I'm not a fucking crook either!"

"Then why are you so close, keep a safe distance!" Xu Moliang crossed his arms, expressing that no approaching is allowed.

Ye Han's whole body is not well, and he simply backed away neatly, thinking to himself who sent this second-hand product? This is God sent to play with me, right?

The soldiers who saw this scene snickered.

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

"What are you doing?" Ye Han had no intention of moving forward at all.

"This!" Xu Moliang pointed to the 3D model of Phobos, "I drew lines on the model, and each point has a label. I will trouble you and your troops later... Uh, drill holes in order!"

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

"Of course it's to see Deimos." Xu Morliang said naturally.

"Wait a minute, what are these lines?" Ye Han asked, pointing at the 3D model.

"This one, it's simple!" Xu Morliang also pointed to the model, "Did you see, there is a hill here."

Ye Han nodded: "I see, then what?" Three lines were drawn on the halfway of the hill on the model, enough to cut off the peak.

"Now we only know the situation on the surface, but I need to know the situation deep in the ground." Xu Moliang pointed to the first line, "This mountain is especially suitable for blasting. If the ground is full of stones, then this line Hole blasting; if it is gravel or water ice,

Then blast on the second line; no matter how bad it is, start the last line of blasting. No matter which line is blasted, the top of the mountain that will be cut off will have a million tons. "

It was only then that Ye Han understood Xu Moliang's intention of drawing so many lines. Looking carefully, all the protrusions on Phobos 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 here?"

Xu Morliang saw clearly what Ye Han was pointing at, and then said unhurriedly: "There is probably a meteorite here. According to the area of ​​the crater, if the meteorite is still at the bottom of the crater, it must be in this circle!"

Is that all right? Ye Han couldn't believe his ears.

Xu Morian 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 picture."

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

It's not that he has a small stomach, but that Xu Morliang's attitude is really annoying. Why didn't you realize that he was such a person when we first met?

But it's not too late to know now, Ye Han immediately asked: "What do I use to make holes?"

"There is a drill rig behind the engineering boat, so you don't need to dig too deep, just take a sample at 20 or 30 meters." Xu Moliang said.

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

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

The engineering boat approached the hill slowly, leaning over it at a slant. Suddenly, several ropes were pulled out around the boat, and the steel anchors on the rope heads were deeply inserted into the ground. Then the engineering boat tightened the cables and pulled the engineering boat towards the hill. Just fix the engineering boat on the side of the hill, almost vertical on the mountain wall.

The driver started the drilling rig, and the drilling rig placed behind the boat stood up automatically. The drill bit first pressed to the ground, then rotated rapidly, and drilled into the ground in a short while.

Ye Han didn't think much, Xu Morliang frowned deeply: "No, the drill speed is too fast!"

Ye Han was very puzzled: "Is it getting better soon?"

"Of course not. The faster you drill, the lower the density. Do you understand?"

"I understand now... what is the density now?" Ye Han saw that the drill bit had penetrated seven or eight meters underground.

"It's very low, it's basically water ice." Xu Morliang's eyes froze, and his voice was very low, "This kind of density can't be used at all...Forget it, I've beaten it, go ahead, drill me deeper , take a few more samples!"
