When it comes to deep space exploration networks, the moon is naturally part of it.

The Queqiao relay satellite currently operating in lunar orbit and the lander on the lunar surface can be counted as a detection node.

The Explorer robot has been exploring a large area since it landed on the surface of the moon on May 11.

Because the Queqiao relay satellite is large enough and has a strong broadcast capacity, the landing process that day was broadcast live, although it is a 720P video, but the bit rate is very high, and the picture is clear and smooth.

If it is the original design of the Magpie Bridge, it is likely that due to insufficient bandwidth, in order to leave enough information channel for the operator, the picture will be abnormally blurry and stuck.

Although the Chang'e-3 mission has landed in front of it, Chang'e-4 is still very popular, because everyone is very concerned about the lunar rover with a different style: the Explorer Big Spider.

After all, although there are not no strange-looking detectors in the past, it is really the first time to see a spider-shaped one, including a large number of foreigners watching it on the Internet.

When the cratered surface of the moon appeared under the camera, Lin Ju's first reaction at that time was desolate, too desolate.

A lander hovering in a low lunar orbit in preparation for landing quickly skimmed over the lunar surface and then slowed down at the right time.

The process does not have a change in data that does not discern anything for the average person, but does not prevent them from being surprised.

Many people's impression of the landing is that the lunar surface in the picture is getting bigger, the crater quickly changes from a small circle to a huge peak and then disappears out of the picture, and the lunar soil is magnified in front of the eyes and is similar to looking down in the near-moon orbit, but the picture suddenly stops because the lander has stopped.

That's when people reacted: Oh, it turns out that the dust that just flew up was rushed up by the air current.

At least in the live broadcast, the process of landing on the lunar surface is very deceptive, so you can see that Armstrong is still very technical to manually operate the lander landing in the case of a computer crash.

The camera switches from below to above the lander, and then the lander lowers two folded alloy hollow plates to form a ramp, in which a lunar rover identical to Yutu-1 slowly appears, and then drives down the ramp at a speed that makes it doubtful whether it is slow-moving, leaving its own mark on the lunar surface with a roller.

The 150-kilogram Yutu-2 actually generates only 25 kilograms of downforce under low gravity, which is almost like a shopping cart with a lot of stuff.

There was applause in the command center and in front of the television, but not as eagerly as expected.

Because they're waiting for the second probe to come down.

It's just that Yutu 2 has already started its own walking, and the explorer robot has not appeared for a long time, which makes people wonder if something is wrong.

And in the command center of Chang'e-4, such a scene is happening:

"Hurry up, farther away, or what if you pounce?"

"Can't you walk down? What are the two ramps for, you have spent so much effort on electronic control and it is not for the sake of good looks, you can't do this. ”

The two sides of the dispute were the control group of the two rovers of Yutu-2 and Explorer, and while the two sides were talking to each other, Yutu-2 walked five meters, and then began to slowly turn and prepare to shoot each other.

All the viewers who watched the live broadcast were a little confused at this time, and did not understand why the explorer robot did not move, and when they were focusing their attention on Jade Rabbit 2, a gray figure flashed from above the camera.

The Explorer Robot uses its eight spider legs to make a strong effort and jumps straight off the lander!

In the live broadcast screen, I saw a monster that was one circle larger than Yutu No. 2 suddenly falling from the sky, and then fell heavily on the traces of Yutu No. 2, completely destroying the maiden line of Yutu No. 2.

When the Queqiao relay satellite transmitted back the amphibious transmission footage taken by Yutu, people saw the explorer flying in the sky.

The timing was just right, it was captured at the highest point of the explorer's jump, and the explorer in the air spread his eight claws like an alien monster.

When Explorer 1 landed with the potential energy accumulated from a high place, the eight spider legs that had been accurately timed were lowered in turn, and the explorer was firmly stopped.

Then, like a real spider, the mechanical spider uses its flexible eight legs to turn its direction in place, and the integrated photoelectric detector on the front end is connected to the main body by a micro-robotic arm, which is as stable as a chicken's head.

From the lander's camera, the Explorer's flattened photodetector makes it look more like a crab than a spider.

Controlled from the ground, the explorer cocks one of its forefeet and gently swings it towards the camera.

This movement is much more flexible than in the ground test, and the explorer, who is difficult to move freely on the surface, has turned into a little elf on the moon, revealing agility everywhere, which is in strong contrast to the stunned Jade Rabbit 2.

However, the latter did not just look at it blankly, in front of the lunar rover, the flag that was originally in an upside-down and folded state suddenly stood up like rabbit ears, which indicated their identity as visitors to the earth.

Explorer-1 did not have a flag available, but pointed the photoelectric detector at Yutu-2 and transmitted back the impact of flags in both directions at the same time.

Everyone in the command center of the Chang'e-4 mission applauded enthusiastically, but Xinyuan's engineers were very regretful.

Originally, the idea was to take a large flag, like the Star-Spangled Banner of the Apollo program, and then use the Explorer robot to drill a hole into the ground, which was completely possible.

However, the space agency disagreed with this in every possible way, and finally simply fooled the past on the grounds that "this matter is left to the manned landing".

After all, it was the first flag, and the space agency certainly didn't want it to be planted by a private company, in which case the project leader would have to write a review.

So let's get a mini flag for Moon Rabbit II. It would be nice to have a symbolic meaning.

In the live broadcast screen, the host's introduction to Explorer 1 is also a little cold, and it is completely businesslike, but this can't resist people's enthusiasm.

Although the name "Explorer" sounds a bit different from the traditional Jade Rabbit and Chang'e for the Chinese people, the explorer full of science and technology is much more interesting than the dull Jade Rabbit 2.

It's a pity that the live broadcast source is uniformly organized and broadcast by Queqiao, and there is also a prior process planning, otherwise if the explorer's picture is independent, the ratings may be higher.

However, the live broadcast was very short, and it ended after the two rovers completed the two cameras shooting each other, but before the end, the explorer specially adjusted the angle and let the lander send back a clear photo of the machine.

The explorer stretched out a spider foot on the side and gently placed it in front of the solar panel of Yutu-2, looking like two friends hooking shoulders on their backs.

After leaving a great shock to the audience and the world's astronauts, the explorer disappeared like a ghost, and only a few photos were occasionally sent back by Yutu-2.

But in reality, Explorer 1 was quite busy.
