"We need to adjust the speed of the centrifuge." Wen Feng squatted down, and the unique coolness of the soil came from his fingertips. "To simulate 75% of the Earth's gravity, the stirring frequency must be reduced to 12 revolutions per minute." As he spoke, the LCD screen on the side of the cultivation box reflected the figure of observer Luo Zhi - this expert sent by the Academy of Agricultural Sciences was recording the reaction data of the lunar soil modification reagent. The gray-white lunar dust in the test tube gradually showed brown spots under the catalysis of the enzyme.
When the dome skylight switched to noon mode, Wen Feng had already changed into an extravehicular suit with magnetic boots.
At the solar array installation site, twenty "moon bunnies" were hopping forward in low gravity. He saw Engineer Zhao from the industrial team, wearing panoramic goggles, directing the automated paving robotic arms like he was conducting a symphony.
The moment each hexagonal photovoltaic panel lands on the ground, lunar dust rises and slowly settles, like a sandstorm in slow motion.
"Hold on to the support in Area B!" The communication channel was filled with the rough roar of the engineering team leader.
Wen Feng pressed the buckle of the safety rope around his waist, and the magnet on the sole of his boot made a slight clicking sound when it came into contact with the lunar surface.
Above his head, the earth was hovering in the sky at the junction of Cancer and Leo, and the blue and white halo gave the silver-gray solar panels a dreamy rainbow.
When installing the third piece, he suddenly found tiny cracks at the seams - this was the masterpiece of the 3D metal printer. The 300-degree temperature difference between day and night on the moon was testing the durability of the material.
It was 4 p.m. Earth time when we returned to the airlock. When Wenfeng removed his helmet, sweat dripped down his brow into the recovery tank. This salty liquid would enter the water recycling system that night and become drinking water for tomorrow's breakfast.
The electronic screen in the locker room shows the base's energy reserves: the helium-3 fusion reactor supplies 82% of the electricity, the newly installed solar array contributes 15%, and the remaining 3% comes from the sports power generation device in the gym.
At dinner, the surprise brought by the planting team made the cafeteria bustle with excitement.
The first batch of water spinach from the soilless cultivation chamber was stir-fried with garlic and still exuded fragrance even when packed in a special anti-spill lunch box.
Wenfeng watched Director Zhang from the medical team carefully pick up a vegetable leaf and chew it for a full twenty times. He suddenly remembered that every cell in these vegetables had experienced the test of a radiation shielding cabin.
When Luo Zhi announced that the soybeans grown in black soil had successfully formed pods, someone knocked on the titanium alloy plate with a spoon, and the impromptu percussion music created sound waves with the aroma of vegetables under the dome.
During the last inspection before nightfall, Wenfeng floated into the soilless cultivation cabin alone.
After turning off the main light, under the purple fluorescence of the crop growth lamp, the leaves of the bok choy are stretching at a speed visible to the naked eye.
He placed his palm on the observation window and suddenly heard a slight crackling sound coming from the black soil cabin next door - that was the soybean pods simulating the circulation system of the northeast night wind.
On Earth, in the Beijing Aerospace Command Hall, Xiao Zhen goes to the command hall every day to observe various work monitoring screens on the moon during the day.
This way he could feel at ease when he saw the staff at the lunar base eating the qualified vegetables they grew for the first time.
Excited applause also rang out in the Earth's command hall and did not stop for a long time.
Xiao Zhen really wanted to eat something grown on the moon, but that would take two years.
When he returned to his home at No. 95 Nanluoguxiang, Zhenxi and Niu Yuesheng were already waiting for him in the study.
"You guys are making quite a fuss, aren't you?" Xiao Zhen said with a smile as he put down his bag.
"Dad, did we make a lot of money this time?" Zhenxi asked
"Is it a lot? Not much. You must always remember what has happened since 1840... It's just a little bit of interest!" Xiao Zhen patted the two on the shoulders and said indifferently.
