Vol 2 Chapter 1740: Deep space probe

Is it possible for this'Oasis 2'inflatable inflatable space experiment module to dock with our space station while it is in orbit? Zou Huanyi, who has been looking at the model of the inflatable and inflatable space experiment module of the "Oasis II", came up with such an idea.

　　 Hearing this thought, everyone was stunned for a moment, and then began to discuss. But while discussing, everyone looked at Qin Xinghe.

　　 Everyone knows that the biggest problem with this idea lies in the space authorities. As for Wu Hao, if they had such a good opportunity, they would definitely not refuse.

　　 For Wu Hao, docking with the space station is what they have always hoped for, but there has been no response from the space authority, which also caused this plan to fall into disarray.

　　 Originally, he had no hope, but he didn't expect to be mentioned again by Zou Huanyi.

　　 Hearing Zou Huanyi suddenly put forward such an idea, and felt the eyes of everyone. Qin Xinghe smiled bitterly, then shook his head.

"Any spacecraft docking in orbit is at risk, not to mention the experimental'Oasis II' inflatable inflatable space experiment module. Many new technologies are used on it. The docking includes docking. Will it affect our space station in the future, or even bring danger? No one of us knows this now.

　　 Regarding this idea, in fact, Xiao Wu and the others have also applied to us several times, but at present, there are quite large differences in opinions on this idea in the bureau, and it is difficult to establish a unified consensus at present.

　　 I think it’s better to let Xiao Wu do it themselves first, and it’s not too late when the technology is really mature. "

　　Although Qin Xinghe said that, everyone knows the implication in his words. This is obviously a tactful rejection. Although Qin Xinghe's words have some truth, everyone still feels sorry for the death of such a good idea.

　　 Zou Huanyi sighed and said nothing. This idea was originally inspired, and since both parties have contacted before and have reached a conclusion, then he should not insist on it. Especially in the presence of so many people, if you speak up again, you will be too incapable of being a human being.

　　 Actually, it doesn't matter, there will be more opportunities for cooperation in the future. Besides, the effect of docking with our manned spacecraft is the same. Wu Hao smiled and solved Qin Xinghe's siege, and then changed the topic: "Please, everyone here, this one shown here is a deep space probe designed by ourselves."

　　 Oh, after hearing Wu Hao's introduction, everyone gathered around the platform, looking at the strange model of the deep space probe hanging above the platform.

　　 This model of the deep space probe has a rather peculiar shape. It is not the same as the umbrella-shaped shape of the solar edge deep space probes released by our country earlier, and those border probes in film and television dramas.

　　 As for the deep space probe suspended in mid-air above the booth, it also comes out of two parts, with a long truss support rod connected in the middle.

　　 At the front end of the truss, it is mainly its energy system, navigation control system, and various detection equipment and instruments.

　　 First is the energy system, which is the most important part of the deep space probe. Because the flight distance is relatively long, the sunlight received is relatively weak, so the efficiency of solar panels alone must be somewhat low. At present, most of the deep-space detectors that have been launched in the world are driven by nuclear batteries. To put it bluntly, they are powered by radioisotope thermoelectric batteries. The low temperature in the universe and the high temperature of radioisotopes are used to form the difference between high and low temperatures. Generate electricity.

　　 This kind of nuclear battery has one advantage, that is, it is relatively stable and has a longer working time. The disadvantage is that it is technically difficult, costly, and has radiation. But in the universe, this point of radiation is nothing. As for the high cost, such a large project, this point of cost is nothing. The prosecution of countries is really stuck in this area of ​​technology. At present, the cutting-edge technology in this area is mastered by Lao Mi, and it is strictly blocked and controlled. Although our country has already conquered this area of ​​technology, it just started late, and there must be a certain gap compared to Laomi.

Although Wu Hao and the others are also equipped with isotope thermoelectric batteries on the'Wangshu' intelligent lunar patrol rover, the main technology comes from scientific research institutes in the aerospace system, although Wu Hao and others have improved on the original technology. . However, the performance improvement brought by such an improvement is still relatively limited.

　　The isotope temperature difference battery on the "Wangshu" intelligent lunar patrol rover is not directly used to start and supply the operation of the entire vehicle, but to serve as a backup power source and emergency electricity. In addition, the continuous heating of the radioisotope battery can also keep the instruments and equipment on the "Wangshu" intelligent lunar patrol rover through the long moon night.

　　 So trying to drive such a deep space probe directly, according to their current technology, is still slightly difficult.

　　 But in the face of the complex cosmic environment, a stable and long-term power supply system must be available. UU Reading www.uukanshu. com isotope thermoelectric battery is the best choice. Therefore, at the top of this deep space probe, two isotopic thermoelectric batteries were designed and installed.

Similar to the function of the isotope thermoelectric battery on the "Wangshu" intelligent lunar patrol rover, the main function of the two thermoelectric batteries is to provide long-term stable power output to ensure that the detector will It can also rely on these two isotope thermoelectric batteries to maintain normal operation.

　　 In order to make up for the insufficient performance of the two isotope thermoelectric batteries, researchers equipped this deep space probe with a huge solar sail.

　　 The technology of solar sails is actually not new, because this technology was proposed as early as the 1970s.

　　Solar sail, as the name suggests, is similar to the sail of a sailboat. It uses the sun to power the solar sail and then propel the entire probe forward.

　　 Of course, here is the light pressure generated by sunlight. It's just that the light pressure generated by the sunlight exerts a small thrust on the spacecraft and the existence of air resistance prevents the spacecraft from taking off from the ground.

　　 But in space where there is no air resistance, this small thrust can still provide an acceleration of about 10e-5 to 10e-3g for a solar sail with sufficient sail area.

　　 The solar sail designed by the researchers for their deep space probe is very huge, fully unfolding to nearly 800 square meters, which is considered a giant in space. What kind of concept is this? After unfolding, it will be about the size of two basketball courts.
