"The landing site of the Chelome probe is 95 kilometers southwest of Kunlun Station. I have sent you the specific longitude and latitude. The probe consists of two parts, a lander and a rover. I have already contacted the landing site

We have made contact with the transmitter, but the patrol device is currently out of contact... The Chelome is currently in a semi-sleep state, its power is very low, and it sends me a signal every five minutes."

"OK, thank you for your assistance, Miss Maidong." Old Cat opened the garage door, "Please continue to track and pay attention to the Chelome."

Tang Yue and Lao Mao stood in the garage. In front of them was the tall front of the Mars Stray Dog. The polygonal cab protruded forward and was inlaid with dark glass.

The distance between the Chelome probe and the Kunlun Station is nearly 100 kilometers. There is no doubt that it is impossible to walk such a long distance. They can only drive a Mars rover to find the probe.

"The average Martian stray dog ​​can run up to thirty kilometers a day. It charges during the day and drives at night. So it should take three to four days to run 95 kilometers, and it will take six to eight days to go back and forth." Tang Yue leaned against the wall of the garage.

, looking up and down the body of the rover, while calculating the time, "In six to eight days, Mingguang Kai's life support system alone will definitely not be able to carry it, so we have to move the OGS system up. In this case, we will have to transform it."

Mars rover…”

Tang Yue thought about it in his mind. It is quite complicated to move the OGS cabinet into the car. After all, it is not an air conditioner. It is not as simple as just moving it to another place... The experimental cabin of Mars Stray Dogs is airtight.

It saved a lot of trouble, otherwise how to seal the cabin would have been a big problem. He couldn't wrap the entire car tightly with tape.

"In six to eight days, we have to carry at least ten days' worth of food and fresh water. This weight also has to be considered. The space in the experimental cabin is limited and it will definitely not fit. We have to pack them and put them on the roof of the car."

"There is also the issue of power supply. We must bring solar panels, and we must carry enough solar panels to meet the needs of stray dogs." Tang Yue leaned on the car door and turned to look at the battery farm in the distance.

Neatly arranged panels reflect the sunlight.

Usually the Mars stray dog ​​is parked in the garage, and the battery farm will provide it with energy. The battery is usually fully charged, but if you want to drive this electric car a hundred kilometers away, you need to bring the battery panel with you -

- On Mars, solar panels are not an efficient power source. They are capable of supporting scientific research instruments, but they are difficult to use to drive cars, so the charging process is as slow as a turtle crawling.

There are two battery panels on the roof of the Mars Stray Dog, but those two batteries are not used to power the engine, but to power the experimental cabin.

"The maximum power of the Mars Stray Dog is 30 kilowatts. If all the power-consuming instruments in the experimental cabin are removed, an OGS cabinet is installed, and an RTG can be used as the heat source. This thing does not consume electricity, then the power of a solar panel is 200 kilowatts.

Watts, we have to carry a total of..." Tang Yue began to calculate how many batteries he needed to bring.

"No need." Old Mao shook his head and interrupted Tang Yue.

Tang Yue was startled.

"We don't need an OGS system, we don't need an RTG, and we don't need to modify the Mars stray dog." The old cat knocked on the wheels of the Mars rover. These huge wheels are not filled with air, but with a fine metal mesh.

"Without OGS?" Tang Yue turned around, "What about oxygen?"

The old cat looked at him with burning eyes and said word by word: "You don't need oxygen."

Tang Yue was shocked. He suddenly realized what the old cat meant... Yes, they don't need to modify the Martian stray dog, they don't need to install an OGS cabinet, and they don't need to carry RTG and supplies, and all life support

The system doesn't need it, because Tang Yue doesn't need to participate in this operation at all.

The old cat never thought about asking Tang Yue to go with him from the beginning. It would be fine as a cat. It does not need oxygen, heat, or life support system. It only needs a car and a bunch of batteries.

.

This is the simplest way. It’s too much work to modify the Mars Stray Dog, it’s too troublesome to move the OGS cabinet, the food and fresh water are too heavy and take up space, and it’s hundreds of kilometers away, with no village in front and no store in the back.

An accident happened on the road, and the consequences were disastrous.

"Are you going alone?"

The old cat nodded, "I will go alone. I will only drive the Mars Stray Dog, unload all unnecessary things, take away half of the battery, and don't need anything else. This is the fastest, easiest, safest and most secure. You

Stay at Kunlun Station and I will try my best to come back within seven days."

"Mr. Cat, go by yourself?" Maidong asked, "Will there be any problems?"

"If even I can have problems, then it will be a dead end for Tang Yue to follow me." Old Mao shook his head.

"But one more person will take care of you." Maidong said.

Old Mao glanced at Tang Yue, "What kind of care is he? He's just a burden."

Lao Mao and Tang Yue started to work, unhooking the hinges, unloading the geological experiment cabin, and replacing the cart. The cart is just a bed board with two wheels, no power and no suspension. This is the simplest and lightest Mars stray dog.

The state of - tractor form.

What Old Cat has to do is to tow the Chelome back, so it only needs a tractor.

A stray dog ​​in tractor form can reach top speeds, surpassing a Feige bicycle.

During this period, Tang Yue returned to Kunlun Station to have something to eat. Lao Mao drove the stray dog ​​out of the garage, and then the two began to pack up the solar panels.

"On an average Martian day, the effective charging time is eight to nine hours, no more than ten hours..." Lao Mao folded up the solar panel and placed it on Tang Yue's trolley, "I can only charge during the day.

, from 6 am to 6 pm, and then travel at night.”

"How many battery panels do you need to bring?" Tang Yue asked.

"First ensure the normal operation of Kunlun Station, and I will take away all the rest." Old Mao put the battery panels on the cart and folded them, "How much electricity do you use at Kunlun Station?"

"I can turn off most of the functions in Kunlun Station and only keep the life support system and communication system. The temperature can still be maintained in a short period of time with the RTG." Tang Yue calculated in his heart, "Thirty battery panels are enough.

Already."

"Okay, I'll take the remaining ten solar panels with me." Old Cat nodded, "Ten panels, each with 200 watts, which is 20 kilowatt-hours in ten hours, should be able to run thirty kilometers in one day.

Then it will take three days to set off from Kunlun Station and arrive at the landing site of the Chelome...if everything goes well."

Tang Yue and Lao Mao piled ten battery panels onto the cart and tied them tightly with cables.

"You won't fall off in the bumps, will you?"

Tang Yue pushed the stacked battery panels hard, and they seemed to be tied tightly.

"Won't."

The old cat found a large piece of plastic sheet and covered the battery panel to prevent wind and sand. He carefully tucked in all the corners. After all, the battery panel is the lifeblood of Kunlun Station.

By the time everything was sorted out, the sun had already set.

Tang Yue walked around the Martian stray dog ​​several times, checking and thinking at the same time. He was like a traveler before leaving. Even though he had packed his luggage, he couldn't stop checking it again and again for fear of leaving something behind.

"Can you come back within seven days?"

"I'll try my best." Old Mao patted Tang Yue on the shoulder and asked him to squat down, "Don't be a monster when you stay in Kunlun Station. Don't eat or drink randomly. Don't mess with electrical appliances. Don't dismantle OGS and RTG.

, don’t cultivate to achieve righteousness, be sure to pay attention to safety.”

Tang Yue nodded.

"Wait until I come back." The old cat touched Tang Yue's mask with his forehead, "Good Luck."

The old cat turned around and climbed into the Martian Stray Dog's cab, started the car, and the Stray Dog started slowly with vibrations. The front of the car twisted, dragging the cart and battery panels towards the boundless desert.
