Great Country Academician

When the Xinghai glided from the runway to the sky with swaying red and purple tail flames, CTV's broadcast truck also captured the stunning scenery in the live broadcast room.

In the darkness of the night, the splendid scenery, like a divine phoenix flying through the nine heavens, made countless viewers in the live broadcast room marvel and marvel at it.

【so beautiful! 】

[Is this the legendary electric propulsion engine? The colors of the tail flames are so charming. 】

[The phoenix emerges from Nirvana, its wings are like a rainbow, and it spreads its wings! 】

【What a poem! However, I am uneducated and can travel all over the world with just one word! 】

[Follow one sentence: Damn it! 】

【Me too! 】

[True scientists are the only gods of mankind! Whoever can build this kind of electric propulsion system is awesome! 】

[Kawagami: Well, you can praise me openly, there is no need to beat around the bush. 】

As the Xinghai took off, Sun Yutong, who was presiding over the broadcast at the space base, also recovered from the shock.

Although I have seen the launch process of Xinghai from news reports and videos before, this is the first time I have experienced it all from such a close distance.

Especially in this quiet night, the red-purple flames trailing on the tail of the space shuttle are extremely bright and brilliant, which is shocking.

Looking at the Xinghai that had disappeared in the sky, Sun Yutong took a deep breath and said quickly with an excited and rosy face: "Dear viewers, the Xinghai has successfully set sail, and its end point will be the moon we look up to. Let us Let’s pray for the astronauts and hope they have a safe journey.”

As soon as he finished speaking, a large area of ​​flowers and candles filled the live broadcast room.

After three seconds of silence, Sun Yutong continued the live broadcast: "The launch of the Xinghai was a complete success. The subsequent live broadcast will be transferred to the live broadcast equipment on the Xinghai as planned. Let us follow in the footsteps of the Xinghai. Climb into that starry sky.”

Now that we are ready to broadcast the entire process, the footage of the Xinghai's flight will naturally be broadcast live as well.

This is not difficult for Xinghai Research Institute. The space shuttle itself has a shooting device, which can directly intercept part of the picture and put it into the live broadcast room.

In addition, in order to allow the audience in the live broadcast room to enjoy the beautiful starry sky, Xu Chuan also specially added a shooting device to set the corresponding exposure parameters to shoot the starry sky.

This is different from the camera methods used in conventional aerospace activities. In conventional aerospace photography, whether it is the American Apollo 11 or the Chinese Shenzhou 14, when the astronauts are active, the starry sky background is pitch black. All the stars in the vast starry sky disappeared.

What causes this phenomenon is not the "bizarre disappearance" of these stars, but the "selection" of the camera's exposure parameters.

To put it simply, in the universe, stars are relatively dark subjects; while space stations and astronauts illuminated by sunlight will become very bright.

But the camera cannot 'see' both bright objects and particularly dark objects clearly at the same time.

How to choose in this case?

Obviously, during extravehicular activities, capturing the details of astronauts, space station modules, and the Earth is the first priority. That is, setting corresponding camera exposure parameters based on bright objects as the standard.

This has led to the fact that almost all the images captured in previous space activities have a dark cosmic background.

As for the live broadcast, it must be as beautiful as it is beautiful, so Xu Chuan arranged for a camera to shoot stars, using long exposure to shoot the star sea in the universe when the Xinghai was sailing between the earth and the moon.

After all, the voyage takes a relatively long time, so we can’t always show a dark background.

On the other side, the main control center of the space base.

Unlike the relaxed mentality of netizens watching the live broadcast of the moon landing, the staff in the main control room were busy at their jobs in an orderly manner.

Looking at the picture transmitted back by the Xinghai, Xu Chuan stood in front of the main monitoring screen, pinched the headset, and said clearly and calmly: "Call the Xinghai, this is the ground command center, please report your situation."

After a brief silence, the astronaut's voice quickly came back to the headset.

"This is the Xinghai. The current altitude is 6,000 meters. The current flight speed is 2735.45KM/H. The fusion reactor output power is 9.65%. The aerospace engine output power is 26.77%. The feedback from all parts of the Xinghai equipment is in good condition!"

"The ground center received it, please Xinghai act according to the established plan and maintain stable contact!"

"Xinghai received it!"

Compared with traditional chemical fuel rockets, Xinghai takes longer to send itself to low-Earth orbit, and its acceleration is relatively smaller. In the atmosphere, although the flight angle is always upward, the astronauts are not under great pressure and can even move normally.

In front of the console, Xu Chuan also breathed a sigh of relief after receiving the answer from the Xinghai.

Landing on the moon is a long journey. No one can guarantee whether China's footprints will be imprinted on that moon palace.

But at least, they have taken the first step and it is going smoothly.

The rest is up to God.

Although as a scientist he is not superstitious, but after he has tried his best to do his best, facing the vast sea of ​​stars, all he can do is pray.

"By the way, where is the Artemis lunar landing ship in the United States now? How long until they land on the moon?"

In front of the console, Xu Chuan suddenly remembered something and turned to Academician Chang Huaxiang standing next to him and asked.

In recent days, he has been preparing for the launch of Xinghai, and he really hasn't paid attention to NASA's detailed planning.

Hearing this question, Academician Chang Huaxiang also frowned. After thinking for a while, he shook his head and replied: "I really don't know much about this. I really don't pay much attention to the situation over there."

Like Xu Chuan, as the person in charge of the planning of the manned moon landing project, he was also very tight on time and did not pay much attention to this aspect.

Xu Chuan nodded and was about to say something when Wu Yuankang, director of the space agency, smiled and spoke.

"I know this. The Artemis lunar lander was launched on time at 1:30 pm on the 17th. It stayed in low-Earth orbit for 42 hours for inspections and two orbit adjustments. It was launched in the early morning of the 19th. Entering the Earth-Moon orbit at 7:30 and heading to the moon.”

"Judging from the latest information collected so far, the Artemis lunar landing spacecraft is between the orbits of the earth and the moon, and it will take about forty-five hours to approach the 100-kilometer orbit around the moon."

"This is the data updated in real time by NASA. Of course, I only remembered it roughly. If Academician Xu needs accurate data, I will check it out right now."

"Need not."

Listening to Wu Yuankang's words, Xu Chuan shook his head and silently calculated in his mind. From the time he set off at 1:30 pm on the 17th, it was already 0:30 am on the 21st, which is about 103 hours.

If it takes close to forty-five hours to reach the 100-kilometer orbit around the moon, then it will take NASA at least 150 hours, or even longer, to land on the moon.

This data, compared to Apollo 11 decades ago, took almost twice as long. He remembered that the Apollo 11 moon landing seemed to have taken about 75 hours.

Of course, this does not mean that the United States' strength in the aerospace field has declined.

On the one hand, the steps designed to land on the moon are quite cumbersome. It can be said that Apollo 11 was able to reach the moon in about 75 hours. It can be said that it was achieved by gathering the strength of the entire United States.

Moreover, the only record of 75 hours of landing on the moon was Apollo 11. The subsequent 12th to 17th took much longer than the 11th.

On the other hand, there is actually not much time left for NASA to prepare this time.

Being able to successfully send the Artemis lunar lander to the moon is already quite impressive despite being in a hurry and even exceeding the project schedule significantly ahead of schedule.

But there seems to be some problem with this time?

In his mind, Xu Chuan thought carefully. It was not that there was something wrong with the Artemis lunar landing craft, but that he felt something was wrong.

seem

Staring at the surveillance screen in front of him and the Xinghai above, Xu Chuan fell into deep thought.

On the side, Academician Chang Huaxiang glanced at him in surprise, but did not disturb his thinking.

After a long pause, Xu Chuan suddenly shouted in surprise: "I know!"

Chang Huaxiang looked over curiously and asked, "Huh? What's wrong? What do you know?"

Xu Chuan quickly replied: "Time! It's time!"

"Based on Director Wu's data, it will take about forty-five hours for the Artemis lunar landing craft to reach the 100-kilometer lunar orbit, and it will switch from a 100-kilometer lunar orbit to a near-lunar orbit of about 15 kilometers. Theoretically, it takes three to five hours, and including the time for launching the lunar module and landing on the moon, it may reach 60 hours."

"If they move slower, theoretically speaking, it is possible for our Xinghai to complete the launch of the 'lunar lander' before them and land on the moon first!"

Hearing Xu Chuan's words, Academician Chang Huaxiang couldn't help blurting out: "Last come first?"

"Is this okay?" Wu Yuankang from the space agency asked quickly.

Xu Chuan nodded, took a deep breath and said quickly: "Xinghai is going to the moon. It only takes more than two days to reach the lunar orbit. According to previous calculations, we should arrive at the moon at noon the day after tomorrow, which is almost sixty hours. .”

"I didn't expect that NASA's moon landing would take longer than usual this time, a full 150 or 60 hours, almost six and a half days."

On the side, Chang Huaxiang made a quick calculation, and his eyes suddenly brightened a lot: "According to the speed of Xinghai, it is really possible for us to be the first to land on the moon."

Xu Chuan nodded and said: "The key now is how long it will take for them to adjust their orbit around the moon! If it takes more than four hours, we have a great chance!"

"I'm going to collect a more accurate time right away!"

After hearing these words, Wu Yuankang quickly walked out of the control center without saying anything. He originally thought that it was impossible to be the first to land on the moon and was blocked by the United States. Unexpectedly, after all the twists and turns, they still had hope.
