Chapter 519 Why do they do this?
After noticing this change, Xu You immediately notified the staff at the control center and informed the two astronauts of the order.
Then, the two astronauts in the picture stopped moving forward and began to wander around.
"The concentration of lunar dust in this area is really too high. If we stay in this area for a long time, it will pose certain potential dangers to our astronauts," said Xu You.
Even though our space suits are very safe, Xu You doesn't want them to take the risk.
Unlike dust on Earth, lunar dust is a very dangerous substance.
They are small in size, like powder, but very hard. If they accidentally enter the inside of the space suit, they will cause serious impact on the astronaut's body.
When the concentration of lunar dust is too high, its danger factor may exceed the critical value of the space suit and cause a certain degree of penetration into the space suit.
"Sure enough, there are some unexpected risks on the moon. What Sam Space Agency told me was not all alarmist," said Xu You.
However, Xu You felt that this might not have a direct relationship with whether or not one was on the back of the moon.
According to existing data, the back of the moon is an area where there is almost no electromagnetic interference from the earth and has a large amount of efficient and pollution-free energy.
If we can make full use of the resources on the moon, humans will not have to worry about resource issues for tens of thousands of years.
After inspection, the two astronauts bypassed the area with excessive concentration of lunar dust and continued to move forward.
The host just learned the news and explained it to the audience.
"Our astronauts just encountered an area with a high concentration of lunar dust, so they changed their direction. Compared with the dust on Earth, lunar dust is much more harmful and may cause diseases such as 'lunar hay fever'. If we want to build a home on the moon in the future, the lunar dust problem must be solved. "
After bypassing an area of high dust concentration, the two astronauts began measuring the gravitational acceleration on the moon.
"As we all know, the gravity on the moon is very low, only about one-sixth of that on Earth. Every ordinary person will become an athlete after arriving on the moon."
At this time, Sui Shihuan bent his knees and jumped high, jumping several meters high, which amazed the audience.
After intuitively feeling the low gravity on the moon, the two astronauts took out the experimental equipment and began to conduct rigorous scientific experiments.
"After rigorous measurements, the gravitational acceleration here is 1.618m/s^2. If you have the opportunity to weigh yourself on the moon, you will weigh the lightest you have ever weighed. However, your mass will not change at all, only the gravity will change."
Except for a few minor dangers, the astronauts completed all their tasks in a very safe manner.
Even so, the two astronauts ultimately decided not to venture to the back side of the moon, an area full of unknowns.
"Old Xu, why do you think the Sam people suddenly warn us not to go to the back of the moon at this time?"
Taking advantage of the break at work, Hu Shucheng found Xu You and asked him questions.
"On the one hand, there are indeed many dangers. In addition to the lunar dust that astronauts have already experienced, there are also moonquakes, meteorites, electromagnetic radiation, etc. The level of particle radiation on the back of the moon is hundreds of times that of the front, and there is no protection mechanism like the ozone layer. Even though our space suits have taken this into account, we should try not to take this risk easily."
"What about the other side?" Hu Shucheng continued to ask.
"On the other hand, there are things they don't want us to know. On the back of the moon, there may be many substances that don't exist on Earth, as well as some excellent resources. With their moon landing plan being hindered, they definitely want us to discover these secrets as late as possible."
"So, we really give up exploring these secrets?"
"No, it is their reminder that makes me want to learn these secrets faster. When the next moon landing, I will definitely discover these secrets."
Xu You did not explain his detailed plan, but just from the expression on his face, Hu Shucheng knew that Xu You was very confident about this matter.
…
A few days later, the two astronauts completed this stage of lunar exploration and prepared to return.
This time, the astronauts not only erected a red flag on the moon , but also completed a number of scientific experiments and collected hundreds of kilograms of geological samples.
These valuable resources will be of great help to our lunar exploration.
With the return flight approaching, the live broadcast of the moon landing project has reached a new high.
"This time our two astronauts have completed their exploration of the moon, but the entire mission is not over yet. Next, the most important thing is that the three astronauts can return to Earth safely and bring back precious lunar samples."
In addition to the attention paid to the moon landing project itself, the safety of the astronauts is also a matter of concern to everyone.
In addition, even though we have obtained some samples from the moon, research on the moon is still in its very early stages.
The several hundred kilograms of lunar samples collected this time will bring a qualitative leap to our research work.
After everything was ready, Sui Shihuan pressed the return button of the lunar module.
Immediately afterwards, the lunar module took off and was about to reunite with Starry Sky 1.
Xu You and others had previously carried out rigorous calculations on all orbital kinematic constraint issues, as well as various orbital changes and docking details.
Once the lunar module and Starry Sky 1 successfully dock, they can return to Earth together.
The most challenging process here is the docking of the lunar module with Starry Sky 1.
The technologies involved are very complex and the requirements for calculation accuracy are also very detailed.
It is no exaggeration to say that the accuracy of spacecraft docking needs to reach the millimeter level to ensure the safety of docking.
Even the slightest error may lead to the failure of docking.
Before we knew it, the lunar module had entered the lunar orbit and was gradually closing the distance with Starry Sky 1.
"From the footage, the lunar module and Starry Sky 1 appear to be stationary, but in fact, their speed relative to the moon is as high as one kilometer per second. It is very difficult to maintain such a close distance when running at such a high speed, not to mention that they are approaching each other at a very slow speed."
