Chapter 1658 [The greatest effect of bringing French and Italian goods]
However, this is a case of good luck. Whether you can find signs of life in the stratum where the Mars landing site is located still requires a certain amount of luck.
However, Fang Hong is not in a hurry. As long as it is confirmed that there is life on Mars, he can always find ironclad evidence. If he didn't find it this time, he will find it next time. It just takes time.
Moreover, the relative distance between Mars and the Earth is close, not as far away as Saturn.
With a launch window of more than two years, it can be reached in half a year's journey, and the time cost of traveling to Mars is several times less than that of Saturn.
Fang Hong will also spare no effort to spend money to support a series of follow-up plans for the Mars exploration project, proving the importance of the existence of extraterrestrial life to the value of building a "community with a shared future for mankind". Needless to say.
…
Fang Hong stayed here for about half a day before leaving, and gained an intuitive understanding of the progress of the entire project.
On the way home, on the private plane.
Yu Qiu, who is the housekeeper of Jingxinju Villa and is responsible for the Natural Science Foundation, said with doubts in his heart: "I still don't understand why the Mars exploration project needs to cooperate with the French and Italians. As far as I know,
, the French people are more of a burden in this project, even if they are just soy sauce, they will not be eliminated..."
That's right, this time the "Mars Express" plan also brought along Ouzhou Xiaofa and Itali, because these two guys have the attribute of a loudspeaker, and it is precisely because of this attribute that they brought these two soy sauce characters.
.
When Fang Hong heard her words, he immediately laughed and said: "It's not just a soy sauce role. I brought these two guys with me without expecting them to make much technical contribution. As long as they don't cause any trouble, that's all."
Yu Qiu became even more confused after hearing this, and she thought that bringing Xiaofa along with her was adding to the trouble.
Fang Hong immediately tilted his head and looked at him: "Just imagine, if we really discover life on this Mars mission, the Grasshoppers and Italians will definitely be more excited than us, and they will be eager to blast a loudspeaker to
The whole world has announced this explosive news, and the biggest role of bringing them to make soy sauce is to serve as witnesses, so as not to say that we are talking nonsense."
As soon as these words came out, Yu Qiu couldn't help but asked curiously: "What do you mean by this? You seem to be very sure that there will be alien life on Mars?"
Fang Hong's smile remained the same: "My intuition tells me that there will be!"
Yu Qiu said angrily: "I've been making trouble for a long time and I'm still fooling..."
Fang Hong laughed and said, "Otherwise? I can't fly directly to Mars, but don't believe my intuition. It's always very accurate. How about we make a bet?"
Hearing this, Yu Qiu rolled her eyes at him, but the next second, she turned to smile and said: "I think I have a good chance of winning, so I took the gamble!"
Fang Hong said calmly: "Then if you lose, come here and get a shot. It will happen sooner or later anyway."
Therefore, this shot was realized in advance.
…
The process for the Mars exploration mission formulated seven or eight years ago is a three-step strategy. The first step is to launch the "Tianwen-1" probe to complete the mission that the earlier "Yinghuo-1" failed to complete.
Then there is the second step of the probe landing on Mars, that is, the "Tianwen-2" probe is sent to Mars and lands on the surface of Mars. "Tianwen-2" will carry a Mars rover "Zhurong-1". Among its tasks
A key indicator is to excavate the soil near the landing site. The "Zhurong-1" Mars rover prepared 52 sample tubes. These tubes are machine-made from special alloys and are all assembled in a clean room.
According to this plan, "Zhurong 1" has the ability to collect samples, but it does not have the ability to directly study and analyze these samples on Mars. The samples need to be sent back to Earth.
It is not easy to send a probe to the surface of Mars, and it is even more difficult to retrieve samples. The whole process is long and complicated.
After "Zhurong-1" completes the sample collection work, the tubes will be thrown directly on the ground along the way, but each tube is marked, because "Zhurong-1" has other detection tasks, and it costs a lot of money to send it
Coming to Mars is not just about digging dirt, it's just part of its job.
Although there are frequent sandstorms on Mars, the Martian atmosphere is thin, so it won't be a big problem to just throw the sample tubes on the ground and leave them alone. And with 52 tubes prepared, it's impossible not to find any of them.
After the sample collection work is completed, the Earth side will prepare for the launch of the sample recovery lander, which will be launched from the Earth and arrive at Mars in about half a year through the Earth Fire Transfer Orbit.
The lander is equipped with two very important devices. One is the "Zhurong-2" Mars rover responsible for sampling. Its mission is to find the sample tubes collected by "Zhurong-1" and then recover these tubes and send them to the lander.
.
Another device is the launcher sent to the surface of Mars through the lander. It is a small rocket that can meet the escape velocity of Mars and enter the space orbit. There is a container inside to store the samples.
After the samples are loaded, the small rocket cannot return directly to the earth because the fuel of the small rocket is only enough to send the samples to the high altitude of Mars orbit. There is no additional fuel to support it to directly send the samples back to the earth, so a dedicated launch mission is required.
Go pick it up.
After the sample return lander arrives in Mars orbit and is ready, the small rocket that has been waiting on the surface of Mars for a long time can be ignited and lifted off, sending the sample into space orbit, and the sample container will be thrown out.
The long-prepared return lander in orbit is grabbed by an external robotic arm and sent into the cabin. There is also a robotic arm in the cabin that will place the sample container into the lander and finally close the hatch.
After this whole process is completed, the sample return lander can embark on the journey back to the earth. After more than half a year of Homann transfer orbit flight, it will be parked in the earth's gravity range. The lander will finally be parked in the atmosphere and land in the northern Inner Mongolia area.
to the surface.
This was the original plan. The entire Mars exploration mission cycle would take nine years to obtain samples. However, over the years, the pace of technological development and progress at Tokyo University exceeded the expectations of scientists at the time.
This chapter is not over yet, please click on the next page to continue reading! Kyushu Blue Arrow’s rocket technology has developed rapidly, as well as the Orbital Reef Space Station, etc., the development speed is astonishing, and a series of advanced technological breakthroughs have been applied.
The sponsor's father was also very anxious, and he was willing to spend money. He would rather fail and try again immediately.
Therefore, the general outline of the entire task remains unchanged, but the details have also been adjusted to take advantage of the situation and local conditions.
Because of the breakthrough in Jiuzhou Blue Arrow's heavy rocket technology and the substantial increase in payload, including the advancement of the Orbital Reef Space Station, the "Tianwen-1" of this Mars exploration mission directly took away the "Zhurong", so that
This directly eliminates a launch window period to send the "Zhurong" Mars rover separately.
According to the adjusted new process, the "Tianwen-1" flying to Mars this time will directly complete the three-in-one mission of "orbiting, landing, and patrolling" at once, that is, completing the three major missions of "replacement, landing, and patrolling" of Mars.
Mission objectives.
This feat is also the first of its kind in the world. If the mission is successful, the Eastern country will become the first country in the world to explore Mars and complete a soft landing mission. When the entire mission plan is completed, it will also become the first country in the world to bring a sudden sample of Mars back to Earth.
country.
The "Zhurong" Mars rover that has successfully landed will collect soil samples from the Martian strata. The plan for returning the samples to the lander and back to Earth remains unchanged, but there will be slight adjustments at the end.
That is to say, after the return lander enters Earth orbit, it will not directly enter the atmosphere, but first enter the orbiting reef space station. At that time, the orbiting reef space station has already begun operation, and as a permanent space station, it is operating while
Expansion expands the size of the space station.
After the samples are sent to the space station, astronauts will take out part of them and store them on the space station, and the other part will be returned to the surface of the earth later.
The purpose of doing this is not only for future research directly on the Orbital Reef Space Station, but also as a guarantee plan. If something unexpected happens when returning to the atmosphere and the sample is destroyed on the last journey, the success will be undone.
In this way, even if the worst-case scenario occurs, there is still a sample stored on the space station.
