As long as there is enough energy, oxygen will not be a problem.

On the contrary, the biggest problem is the water and food that can be carried.

This time the command center did not fail to answer.

"After four hours, the sun will have six hours of direct exposure. You can take advantage of these four hours to drive the lunar rover around the crater.

While looking for valuable rock specimens, try to find a way out of the crater. "

"clear".

Using a hammerhead, he helped Jim knock down a few rubbles on the orange ground and put them in a special bag.

The two began to set up scientific research equipment. After more than an hour, Li Changheng got on the lunar rover and waved to Jim.

"Henry, really don't need me to accompany you to explore the terrain?"

"This is just a crater, and the terrain is flat, there is no danger."

Li Changheng wouldn't let Jim follow. In addition to both of them having their own tasks, he also had a lingering doubt in his heart ever since he decided to land in this crater.

When the lunar module flew over this crater, he had a vision that was several times better than that of ordinary people. With the sun's aftermath, he saw that the crater should be flat.

Still on the edge of the ring pit, an object that looked like a dark metal glow was vaguely seen.

When viewed from the air, this thing is estimated to be 3 to 6 meters in size.

Once Jim got close, he would definitely find it.

It would be okay if it were just rocks containing iron-titanium alloys, but other things would definitely cause huge panic around the world.

As soon as the all-terrain vehicle started to move, a cloud of dust was thrown up on the four wheels.

But unlike the earth, the dust only drifted about half a meter high, and then quickly fell to the surface.

If Li Changheng had not read the information of the Aviation Center, he would still be suspicious.

Even if there is no wind on the moon, the dust will not fall so fast like iron sand.

But after reading enough information, he understood.

The first is that there is no wind and air, and the temperature is extremely low. It cannot form the upward lift of the heated water vapor, so the dust will definitely not rise.

It will only fall directly to the ground in a parabolic shape.

The second is that all lunar dust is produced by meteorite impacts.

If you observe with a microscope, you will see that these dusts are all sharp-shaped crystal structures.

It is not because of wind or friction on the earth that it takes a round, oval or other regular shape.

When objects of this form collide with each other, not only will they not collide with each other, but on the contrary, it is easier to cancel the kinetic energy, and it is easier to be attracted by gravity and fall back to the ground.

Moreover, this can also explain why the stable shape of the footprint appears after the shoe is stepped on in the absence of water.

Because once the lens is squeezed, the sharp parts will join together to form a tighter shape.

Therefore, the denser places with deep footprints can easily maintain a stable form.

He drove the terrain vehicle to the edge of the crater, but he didn't go directly to the suspected problem area.

Because the terrain vehicle is also equipped with live broadcast equipment, there is also a camera equipment controlled by Houston, which will continue to take pictures.

Then, the same as the principle of satellite photography, the signal is transmitted back to the earth via radio waves and displayed directly on the equipment in Houston.

So, he has to try to get Houston to turn off the live broadcast.

Moreover, Li Changheng, who already knew how much electricity the ATV had and how far it could travel, was actually racing on the moon under the gaze of Jim with the live broadcast equipment.

Then countless racing enthusiasts on the earth watched TV with sour and envy. A home in an astronaut suit drove the all-terrain vehicle for more than 30 meters and then drove back.

He even played moon drifting around Jim.

While the people in the aviation center that I watched were frightened, the people in charge of Boeing, who built this all-terrain vehicle, were worried and ecstatic at the same time.

This is a real super invincible advertisement.

And don’t look at it as an all-terrain vehicle weighing only 140 kilograms.

In addition to vehicle-related technologies, it also involves communications, batteries, and lighter materials that are more critical, as well as advanced technologies related to the future.

Li Changheng played for a few minutes and stopped when he saw that the vehicle had only 80% of its electricity left.

Then I stood by the car and explained to the camera why the footprints were clear without water, and why the dust would fall back to the surface soon after being raised.

He even took out the flag of the United States and pushed the flagpole into the ground.

Asking Jim to zoom in on the camera, more than 200 million people on the planet soon saw that the metal-like flagpole was constantly shaking in the air.

Then he explained with a smile that when the flagpole vibrates in a vacuum state, the energy will only be absorbed by the surface, so it will vibrate for a longer time because there is no air.

Then he unfolded the folded flag, which was different from the flag on the earth.

This flag not only has a flagpole inserted into the ground, but there is also a metal rod at the top of the flagpole, which forms a 90-degree right angle with the flagpole to prop up the flag together.

Therefore, the audience can intuitively see that the two metal rods are shaking, driving the flag to form a unique fluttering feeling in the air that is blown by the wind.

Then, before he finished, he talked about why the sky looked all black in the photo, instead of stars.

When it was finally concluded, Li Changheng suddenly smiled.

Thumbs up to the camera, and then said, "I think no one in the aviation center will come out to explain the reason, and it is definitely not that I don't want to explain.

But this is the greatest and most economical advertisement in human history. "

Now let alone more than 200 million viewers, even Jim and most people in the Aviation Center were surprised.

Then stared at the screen curiously, waiting for Li Changheng to explain.

"It's very simple. The more people questioned, the more people mentioned the moon landing.

Even if it is ten or fifty years later, as long as someone is still questioning this matter, the moon landing will never be forgotten, and it will always be the hottest news.

Then, those of us who actually landed on the moon will hide from the side, smiling while watching you mention us from time to time.

So, UU reading www.uukānshu.com guys, you should thank me, and please remember that my name is Henry Lee.

A man who advertised himself on the moon. "

FKU.

The shot returned to Earth.

Among the countless people, only a few people really thank him.

Then the others scolded him shamelessly in their hearts.

Having said so much, it turned out to be to increase his popularity in the end.

However, Li Chang-hyung, who has experienced the information explosion, knows that swearing is often easier to turn into profit than good reputation.

Because gratitude may only exist for a few months or a few years and then disappear.

But after scolding or hating someone, it is very likely that you will remember him for the rest of your life.

Of course, this scolding and hate must not be true hate, it cannot be against the moral bottom line and illegal, otherwise the probability of being cool will be even greater.
