Die on Mars - Chapter 242

c240 Day 336 (1) Old Cat Stroller

“Come on—! Get ready!”

“One! Two! Three——! Harder! Harder——!”

Tang Yue and Lao Mao pushed the Martian stray dog ​​with one shoulder and exerted force at the same time. Each of them gritted their teeth and made a sound of constipation, and their four hind limbs slipped on the ground.

“Try harder—!” Tang Yue roared, “Try harder! There’s still a little bit to go! There’s still a little bit to go!”

The rover was finally pushed forward, and the wheels stuck in the pit slowly climbed out.

“It’s still a little bit close…” Tang Yue’s face turned red from holding back, and he was sweating profusely. He poured all his strength into this last effort, “It’s about to come out! It’s coming out!”

“Did you pull it out?”

Tang Yue lost all his energy and almost fell to the ground. He could no longer hold up the heavy car body. The Martian stray dog ​​slowly retreated, but failed at the last moment and the wheels rolled back to the bottom of the pit.

“Will you die if you don’t say dirty things?”

Tang Yue sat down and gasped for air, leaning on the stray dog’s wheel, and glared at the old cat fiercely.

He was quite annoyed.

They had been hindered by a small trap for more than an hour. Old Cat tried his best to avoid complex terrain when driving the Martian Stray Dog, but it was inevitable that a few sand traps would slip through the trap.

The Stray Dog is really not a good off-road vehicle. The grip of the wheels and the torque of the engine are extremely low. When the old cat stepped on the accelerator to the bottom, he could only hear the wheels idling at the bottom of the pit.

“This is not a rude comment. I am just expressing my deep concern for you. I have been suffering from a long-term imbalance in work and rest and eating irregularly. I wonder if your digestive system and gastrointestinal function are normal.” The old cat also sat down and greeted Tang Yue’s family. He said in a tone of voice, “Does Brother Shit go out on time every day?”

“They meet me on time every day! Don’t worry about it!” Tang Yue replied angrily.

As a normal natural person, Tang Yue’s normal physiological needs are to eat, drink, poop, and sleep.

The most difficult of them all is pulling and scattering.

Spraying is actually relatively convenient. There is a urine collector integrated into the Mingguang Armor. It is divided into men’s and women’s styles and is removable with a total capacity of 1.5 liters. Everyone’s urine on Mars will be recycled and reused. After leaving Kunlun Station, Tang Yue’s There is no need to recycle urine, the urine stored in the collector is cleaned every day.

Along the way, all Tang Yue had to do was suddenly ask Old Cat to stop, then climb down and stand motionless on the ground for half a minute…Old Cat would know that Tang Yue was done.

Although the urine collector is designed to prevent leakage in various postures, users do not trust it, so they can stand instead of sitting.

It would be much more troublesome to pull.

Tang Yue couldn’t stand still for half a minute, and he also had to defecate. Mingguang Armor didn’t have a feces collector, so he would have to poop his pants, and Mingguang Armor wouldn’t be able to wear it.

When we were at Kunlun Station, there was a toilet in the station. The toilet in Kunlun Station could provide one-stop service of suction, cleaning, dehydration, drying, disinfection and packaging, but Mars Stray Dogs did not have this function… So Tang Yue’s savior was an empty can.

This is a rather complicated process: First, Tang Yue had to enter the experimental cabin and seal the hatch to ensure it was airtight. Then he took off his Mingguang armor and put on an oxygen mask. He prepared empty cans and plastic bags and placed them firmly in the On the floor of the experimental cabin, Tang Yue had to be careful during the elimination process to avoid accidentally knocking over the jar – if he did, everything would be over.

In the end, Tang Yue completely sealed the jar full of dark residue and banished it to the deserted Martian desert forever.

“How far have we come?”

“Seventy-nine kilometers.”

“There are still two hundred kilometers.” Tang Yue looked down at the control terminal on the back of the extravehicular suit’s hand, reached out and poked it. The air pressure and temperature data were normal. “The road is long and long.”

“You carry the load, and I hold the horse, welcoming the sunrise and seeing off the sunset…” The old cat hummed and sang a tune that Tang Yue had never heard before. It circled the wheel, looked around, and picked up Stones line the pit.

Today is the third day.

The trip went smoothly in the past three days. The Martian stray dog ​​completed its mission on time every day without any mistakes. As an old dog with a disabled body and a strong will, it can be said that it has dedicated itself to death, and it has carried forward the example of its predecessors such as Opportunity. Their tenacious spirit.

The solar panels are also in good condition.

“Old cat, is there any way to make stray dogs go further?”

“What’s the meaning?”

“Stray dogs can only walk thirty kilometers a day, twenty-four hours a day, and most of that time is wasted by us. Can we find a way to make it walk forty kilometers or even longer a day? In this way, we can The time is significantly reduced.”

“Why are you asking me this question?” The old cat squatted beside the wheel. “You are the engineer. No one knows this dog better than you.”

Tang Yue bit the water supply hose and slowly sucked fresh water from the water bag.

“Because I can’t think of any way. What limits the stray dog’s daily journey is the battery. The battery capacity cannot be increased, and the power of the engine cannot be changed.”

“You already know it very well, why are you still asking me?” said the old cat, “I can’t help you tamper with the law of conservation of energy. I suggested to you before setting off that you should also move the battery from Kunlun Station to the car. This will help you Increase the rover’s daily travel distance, but you refused.”

“The problem is that they don’t match each other at all.” Tang Yue spread his hands, “The parameters are all different.”

“I believe this is a small problem that you can easily solve.”

“If we move the Kunlun Station’s battery onto the car, then all the life support systems in Kunlun Station will be destroyed.” Tang Yue said, “There is already enough life on this planet.”

“But we took away all the solar panels.” Lao Mao said. “The batteries at Kunlun Station lack power replenishment, and the life support system is still unsustainable.”

“Isn’t there an RTG?” Tang Yue smiled, “The meager power of the isotope thermoelectric generator is completely insufficient to maintain human survival, but it is still barely enough to take care of tomatoes. I have calculated it. , if my calculation is correct, the tomatoes should be able to die peacefully…even if the plants cannot survive in the end, there are still microorganisms.”

The old cat glanced at him. Tang Yue’s tone was calm, neither salty nor bland, with the attitude that the funeral had been arranged. He buried human history, closed the Kunlun Station, adjusted the life support system, and settled all the plants. Even careful calculations have been made to allow them to operate on their own without human intervention as much as possible.

Then he can hit the road without worries.

“Have you rested enough?” The old cat put enough gravel into the pit and patted his paws. “After you have rested, come over and push the cart. This time we will push it out in one go.”

“good.”

Tang Yue climbed up and stood beside Lao Mao. He pressed his shoulders and palms against the car and looked at each other.

“preparation–!”

“One! Two! Three—! Try harder! Try harder!”

“It’s coming out! It’s coming out! It’s finally coming out——!”

“Did you pull it out?”

“Holy crap! Will you die if you don’t say dirty things, old cat?”
