Oh, upon hearing Yu Chengwu’s introduction, everyone at the scene couldn’t help but smile.
After traveling 2,500 kilometers back and forth, victory is now in sight. For everyone, one can imagine how they feel at this moment.
Especially being able to see the end point is undoubtedly a huge incentive for everyone.
"Okay, now that our golden meteorite cores are about to be transported back to the Zhihai Lunar Surface Scientific Research Station, when will our first returnable lunar experimental spacecraft be launched?" Zou Xiaodong asked curiously.
He has been busy outside and doesn't know much about this aspect. After seeing that the golden meteorite core was about to be transported back to the Zhihai Lunar Science Research Station, he was not prepared to undertake the return mission of transporting the golden meteorite core.
People are full of curiosity as to when the lunar experiment spacecraft will be launched.
Hearing this question, everyone else present also looked at Yu Chengwu and Zhou Xiangming, obviously they were also curious about this question.
You must know that transporting the golden meteorite core back to the Zhihai Lunar Surface Scientific Research Station is only the first step. Next, it needs to be transported back to the earth. Only this "treasure mission" can be considered truly completed.
.
Otherwise, this golden meteorite core was just transported from one place on the moon to another, which would not make much sense.
Hearing this, Yu Chengwu said with a smile: "At present, our returnable lunar experimental spacecraft, including the Jianmu-9 carrier rocket responsible for this transportation mission, has completed relevant testing work before leaving the factory, and will soon be transported to the Nanhai Space Launch Site by ship.
Vertical assembly is carried out over there, waiting for the optimal launch window to arrive.
According to our current planned launch window, the entire launch time is probably between the end of October and the beginning of November. Of course, arrangements must be made based on the weather conditions at this time, including related tasks.
If the weather conditions do not allow it, or the previous task is delayed, then we can only postpone it to a later date.
You can't just let people come down from the launch tower and then let us launch first. This is definitely not possible."
"That won't be long." After hearing Yu Chengwu's words, everyone couldn't help but react.
"How are the relevant preparations going?" Wu Hao asked.
Compared with rockets and spaceships, Wu Hao is actually more concerned about other preparations. Spaceships and rockets are the key points, and they will definitely not be ignored. What is often overlooked are some things that are not taken seriously by people, but
part of the work that also plays an important role.
Hearing Wu Hao's inquiry, Yu Chengwu nodded slightly and said: "Currently, all preparations are being carried out in an orderly manner. In order to ensure the smoothness and stability of the signal during this mission, this time we applied for a global measurement and control site for the aerospace system.
With the help of three international measurement and control stations, two measurement ships, and domestic measurement and control stations, they will all undertake the measurement and control work of this mission.
The aerospace department also attached great importance to our mission and sent a professional technical team to assist us in our work, so the progress was relatively smooth.
In addition to the ground measurement and control stations and measurement ships, this time we also activated several relay satellites to ensure communication and ensure that a line of communication can be kept open under any circumstances."
"Why is it so complicated this time?" Zhang Jun couldn't help but asked after hearing this. He didn't expect that this mission was so complicated. This was something that had never happened before.
Hearing this question, many people present looked at Yu Chengwu and Zhou Xiangming because they also had the same question.
Facing everyone's gaze, Yu Chengwu smiled and explained: "Actually, all these preparations are made so that this mission can be successfully completed.
All of this ensures the safety of this mission.
Although an important task or purpose of this mission is to transport the golden meteorite core, this is only one of the tasks.
In other words, it is not worth the effort and preparation.
Ours is a returnable lunar experimental spacecraft. An important mission of its launch is to verify the process of the spacecraft landing on the moon and then returning to the earth.
In fact, to put it bluntly, it is to prepare for our future manned spaceflight.
Therefore, the preparations for this mission were all carried out in accordance with manned standards, which is why we attach so much importance to it."
After hearing Yu Chengwu's explanation, everyone finally understood. Indeed, the main mission of this returnable experimental spacecraft is to verify the spacecraft's return technology. They have launched several lunar spacecraft before, and combined many lunar rovers and
Dozens of tons of materials and equipment were transported to the moon.
But so far, they have not carried out an experimental mission of a lunar return spacecraft, which is a key technology for their future manned lunar landings.
You can't just send people to the moon and just ignore it. You have to bring them back to the earth. This is a complete moon landing process.
Seeing everyone nodding, Yu Chengwu continued to introduce.
"In addition, we also conducted focused drills on the final landing and recovery mission to ensure that the landing and recovery mission could be completed smoothly and safely.
Because this time it is said to be a high-speed landing mission, the role of the deceleration parachute is limited, so the shelf carrying the golden meteorite core, including the small return capsule, will land at a faster speed.
Therefore, the original manned spacecraft landing site can no longer meet the mission requirements. For safety, we set the landing site for this mission in the Cold Lake area of the plateau. It is a large uninhabited area and is inaccessible, so it is more in line with landing requirements.
.
In this way, even if the golden meteorite core has an accident during the landing process, even if it falls freely and hits this area, there will be no major problems that will affect the natural environment on the ground."
"On the other hand, this is also for ecological safety. Although the chance of this is very small, no one can guarantee whether this golden meteorite core species that I don't know where it came from will contain some deadly elements that are harmful to humans.
Bacteria, viruses, etc.
Therefore, for safety reasons, this landing mission was chosen in this uninhabited area.
In this way, even if the wrapping layer is damaged during the landing process and the gold meteorite core is exposed, it will not cause a major ecological disaster and endanger the safety of humans and nature."
"Furthermore, because the gold meteorite star core is relatively heavy and there is a lack of attitude control during the descent, its landing accuracy is lacking.
And because the descent speed is too fast, the prediction and reaction time are relatively short. Therefore, for safety reasons, we will choose the wider uninhabited area on the other side of Cold Lake.
In this way, even if there is a large deviation in the landing point, there will be no surprises.
Here, whether it is this golden meteorite star core or the small return capsule carrying the lunar soil samples we have collected in the past. In fact, the landing search will not be as urgent as the manned return capsule, so even if it is placed in Cold Lake
This uninhabited and uninhabited area won’t be a big problem, it’ll just take more time to search.”
