What to do after you do it.

Mu Mu stayed in the station to continue debugging communications, while Shi Teng and Liu Peijia prepared to check the landing site of Cassini Station.

They didn't know what kind of spaceship the Buran was, what kind of shuttle or lander it would be equipped with, the lander that could enter the atmosphere was a bit technical, and the lander that could return to the ferocious atmosphere of the Titan was even more top-of-the-line, and the top-of-the-line cargo had to be equipped with a high-level parking field...... Regarding the landing standards for spacecraft landers, there is a set of "universal shutdown standards" in the world, from level 1 to 4, the higher the level means that the harsher the environmental conditions and the greater the difficulty of safe landing, and the parking stand of Cassini station is at level 5.

Senior.

The Buran's Aquarius shuttle, the world's most advanced lander, was specially designed to fly safely in Titan's dense atmosphere, locking firmly on the ground during shutdown to avoid being blown down by strong side winds.

Stong was a little worried about whether the Buran's lander would be as strong as an Aquarius, and if the shuttle crashed during the landing, it would be doomed.

It's certainly impossible for their stockpiles to last until Mars sends a second round of rescue.

"After all these years, will the tarmac still work?" Liu Peijia and Shi Teng checked each other's condition face to face, and he pushed Shi Teng's shoulder armor hard, and tightened the straps on his waist and abdomen to confirm that it fit perfectly on each other's bodies.

"Who knows?" Shi Teng tilted his head to check Liu Peijia's life support system, "We didn't use the tarmac when we landed. ”

"What if the tarmac doesn't work?" Liu Peijia asked.

Shi Teng's eyelids rolled, glanced at him, and then then pulled the strap on Liu Peiji's body hard.

"Damn...... You tap it. ”

"If the tarmac is unusable, then we have to find a suitable place for them to land." Stong replied, "Then guide them to land, or you think I want to go out at this time?" Isn't it comfortable to hide in the station...... OK, no problem. ”

Shi Teng patted Liu Peijia on the shoulder.

"Brother Shi, eggplant, you must pay attention to safety!" Dai Yue leaned out of the laboratory and waved, and Zhuo Zhi and Ge Zi poked out two heads from under his armpits.

The two stood in the hallway, nodding at them.

"Don't worry, it's about three hours, and I'll be back in three hours!" Stong made an OK gesture, closed the mask with a "click", and turned to unscrew the door of the airlock chamber vigorously.

The hatch opened, and behind it was a pitch-black airlock, and Ston lit the headlamp of the Iron Float.

Liu Peijia followed him and got in.

"Where's the tarmac?" Liu Peijia bent over, bowed down and followed behind Shi Teng, pressing the bulkhead above his head with one hand, and holding the bulkhead on his side with the other, and slowly moved forward, "Old Shi, do you know the way?" ”

"Just follow the safety rope." Sten said, "The yellow safety rope can be followed to the shutdown ......."

He unscrewed open the second hatch, and the wind rushed in with a blizzard, filling the entire airlock chamber in an instant, like a beer that had been shaken abruptly open, and the droplets were almost ejected. Both of them were caught off guard and forced to take a step back, and Shi Teng wiped the snowflakes on his mask and looked at Liu Peijia, who fell to the ground and was covered up.

"Damn, this is a ......" Liu Peijia scolded and got up, shaking off the snow on his body vigorously, "Can you get out?" ”

The light outside the cabin was pitch black, and nothing could be seen.

Stong leaned against the hatch and reached out, and in less than a few seconds, a thick layer of snow had accumulated on his hands.

"It's snowy." Steng shook his hands, the snowflakes in the pillar of the head of the Iron Float were like thousands of moths, and he looked down again, the bracket under Cassini Station had been buried in the snow, and it was conservatively estimated that the snow was at least half a meter deep, and he could not reach his waist when he stepped into it.

Liu Peijia also climbed over to look, looked down with the probe, and then looked forward, although the visibility was extremely low, it was not difficult to imagine that the planet was covered with thick snow at this moment.

"With this rate of snow, it won't take a few days for Cassini Station to be completely buried." Liu Peijia said.

"Have you ever been in Siberia?" Sten said, "Or the Great Khing'an Mountains? ”

"No, what?"

"There is also such a big snow in the winter in Siberia." "The snow can be two meters thick overnight, and when you wake up, the snow can bury the door of your house, and you have to dig a hole to go out." ”

"You've lived in Siberia?" Liu Peijia was a little curious, "Your ancestor was once sent by Stalin to dig potatoes?" ”

"Nope." Stern shook his head, "I saw it in the book." ”

"What book?"

"My Days of Developing Servers for Ubisoft in Siberia"

Stong cautiously climbed out, stepping on the ladder and going down step by step, "Don't come down yet, I'll go down and find out what's going on." ”

Originally, the main building of Cassini Station was erected and suspended, with a one-meter-high elastic seismic support at the base, and a ladder descending from the exit of the airlock chamber, while only a small part of the ladder currently exposed to the snow was buried.

Stong slowly sank into the snow.

He still underestimated the thickness of the snow, which was a meter deep, and when Steng's feet touched the ground, he found that only his chest was exposed.

At first glance, it looks like he was buried alive.

Fortunately, the snow was fluffy, and the gravity on Titan was low, so the snow was not compacted at this depth of a meter, and Sten's movement was not hindered much.

Liu Peijia also followed.

"These are alkanes, methane, ethane, all kinds of alkanes." Stone pointed around, "Now that the temperature has dropped to minus 190 degrees Celsius, the alkanes of the entire Titan will quickly solidify and settle, and only nitrogen will be left in the atmosphere." ”

"That's a bit like a chemistry class you've taken before." Liu Peijia said.

Shi Teng was stunned for a moment, and immediately understood what Liu Peijia meant—the process he described was similar to the cryogenic method of separating mixed gases in chemistry courses, and precipitating different components in the air at different temperatures. When you think of it this way, Titan looks like a giant fractionation tower, with the gas in the tower stratifying, with alkanes settling to the bottom and nitrogen rising to the top.

It's a layered world.

Stong imagined himself walking through a giant fractionation tower—even the bottom of a glass beaker or a test tube.

Since the snowflakes are not compacted, the walking of the two can stir up huge amounts of snow dust.

"Old Shi, are you sure we can find the tarmac this way?" Liu Peijia felt like a groundhog or a native grandson burrowing in the ground, and the two broke through the snow and moved forward little by little.

"I don't think we'll be able to come back!" Liu Peijia then shouted.

In the night when I couldn't see my fingers, I walked hard in the deep snow, and I didn't know the southeast and northwest after taking two steps.

Stong stopped, and he gave up.

In this situation, it is impossible to reach the tarmac on foot.

"Turn around!" Shi Teng pushed Liu Peijia, "Go home!" ”

"What? Not going? ”

"Go, of course." "We just can't go on foot, let's find out if there are any other means of transportation!" ”
