There are more than 30 launch sites on the earth, and after the outbreak of the solar crisis, all kinds of commercial, meteorological, surveillance, civilian and other satellite launch plans have been stopped, and all have been replaced by scientific research satellite launch missions. In the past, at least three rockets were launched every day, delivering huge quantities of supplies and a large amount of scientific and technological equipment into space. However, after the discovery of the "reverse fusion layer" on the surface of the sun, and the possibility of a K2-class civilization being speculated, all launch plans were halted. The reason is simple, the top level of the human government is worried that too many space launch programs will cause misunderstanding of super extraterrestrial civilizations, which will bring disaster to the earth.

However, after Zhao Huasheng raised the paradox between those two prerequisites, and the signal emitted by the Xinghe radio telescope did not receive a response for three days, the possibility of the existence of a super extraterrestrial civilization was reduced, and the large-scale space launch program was immediately resumed.

This is the first space launch mission, the largest of the many launch sites.

It took Zhao Huasheng several hours to get from the Vulcan Solar Telescope base to this launch site. Launch Site 1 is located in the subtropics of the previous Earth period, and now it is summer, so it should be quite hot. However, due to the solar crisis, the average temperature here has dropped to about 15 degrees Celsius, and the temperature can even drop to zero degrees at night.

The weather was not very good today, although there were no clouds in the sky, and there was no sign of rain or snow, but the wind was so strong that even the helicopter was a little unstable. After the helicopter landed, Zhao Huasheng put up his collar and left the cabin with Meng Zhuo and the others. Outside, Wang Tang and the others were already waiting there.

After a short greeting, everyone walked to the launch control room. On the way, Wang Tang gave a brief introduction to the launch mission.

"This launch is the most important part of the entire solar exploration program." Wang Tang said, "We have made some improvements to the Mars exploration spacecraft that was previously deployed in orbit around the earth, installed thermal insulation and radiation protection nets for it, increased fuel reserves, increased the power of engines and communication equipment, replaced relevant scientific exploration instruments, and made many other modifications, and finally transformed it into a manned spacecraft that can serve as a solar exploration mission." ”

Before the solar crisis, the human government led the ambitious manned exploration of Mars, but when the spacecraft was finally assembled and the astronauts arrived, the solar crisis broke out, and the plan was put on hold. Now, its purpose has also been changed, and its target is no longer Mars, but the Sun.

There are many differences between a Mars exploration mission and a solar exploration mission. The closest distance between Mars and Earth is only 55 million kilometers -- of course, this is only the shortest distance in theory, and it is almost impossible for humans to get such a good opportunity in an actual Mars exploration mission. In the original orbit plan of the Mars exploration mission, the length of this orbit is 80 million kilometers, and the "Crimson Heart" spacecraft will take 50 days to reach Mars and enter the orbit around Mars, and then release the lander to carry astronauts to the surface of Mars, and after a three-month investigation, it will take about 80 days to return to Earth.

The distance between the Sun and the Earth is much greater, with an average distance of 150 million kilometers, which is a little more than twice that of the Mars mission. This will inevitably require more supplies and fuel reserves, and the space environment close to the Sun is much harsher than Mars, and Crimson Heart can reach Mars, but it can't get close to the Sun.

Therefore, under the leadership of the human government, the Ministry of Scientific Research has made many improvements to the Crimson Heart, and finally allowed it to take on the task of getting close to the sun.

If there is enough time, it is undoubtedly a better choice to rebuild a solar exploration spacecraft, but unfortunately, the solar crisis broke out too violently and too quickly, and it will take at least five years to build a spacecraft that can travel interstellar - this time, including the initial mission planning, that is, the scientific research department will put forward requirements for the performance and functions of the spacecraft, and then the engineering department will combine the scientific research department to make a study on how to achieve these functions, draw drawings and submit them for review. After the review is passed, it will enter the final construction stage.

The construction tasks are dispersed to tens of thousands of factories around the world for individual manufacturing, and after acceptance, the parts are initially assembled, followed by extensive debugging and testing, after which they are launched into orbit around the earth by rockets. A temporary space station will also be set up to take care of the subsequent docking and assembly of these modules, as well as maintenance tasks.

Each rocket launch can only carry a portion of the spacecraft into space. The assembly of the entire spacecraft required many launches. The Crimson Heart spacecraft carried out more than 100 rocket launches in succession before it was finally assembled in space. In this process, the launch, return, life safety, material support, and coordination and command of the astronauts responsible for assembling the spacecraft are all huge projects.

Among the more than 100 rocket launch missions, there were three failures, because of these three failures, four excellent astronauts died, and three batches of valuable precision instruments were destroyed.

A total of more than one million outstanding scientists, engineers, workers, managers, and logistics support personnel participated in this huge project. It took five years for human civilization to finally pour this great spaceship with its own sweat and blood. But at this last moment, its target was changed from Mars to the Sun, which has to be said to be somewhat dramatic.

"A total of thirty-seven rocket launches were carried out in the later transformation missions. The Crimson Heart spacecraft is excellent, and converting it into a solar probe saves a lot of time and resources than building a new one. Now that everything is ready, Crimson Heart is ready to go to the Sun and make field observations of it. Wang Tang said, "Of course, before that, we need to send these five excellent astronauts to the spacecraft first." ”

Zhao Huasheng stopped and set his gaze on the distance, towering straight upright, like a huge rocket pointing at the sky.

This is the Hercules heavy launch vehicle. With a height of 70 meters and a total weight of 3,500 tons, it can carry 130 tons of payload into space per launch. This is a miracle in the history of human engineering, and it is the largest rocket ever built by mankind.

The Hercules rocket was more than 2,000 meters away from Zhao Huasheng. At such a distance, the magnificence of the Hercules rocket still blows in the face. Anyone who sees this rocket will be amazed at its sheer size and power.

Zhao Huasheng looked at it attentively, not knowing what he was thinking.

Wang Tang walked behind Zhao Huasheng and said in a low voice: "Among the one hundred and thirty tons of payload launched this time, in addition to the five astronauts of three men and two women, there is also a material storage warehouse, as well as supplies stored in the storage warehouse. It has some power, and after the Hercules rocket sends them into space, the astronauts will operate the supply storage bin to dock with the Crimson Heart spacecraft and become part of the spacecraft. The astronauts would then enter the operation module and fly the Crimson Heart spacecraft out of Earth's orbit and toward the Sun. ”

"After all, robots are not as good as humans, and there are many operations that only humans can do. Therefore, scientists have set this mission as a manned spaceflight, and they hope that the instruments on board the Crimson Heart spacecraft and the five astronauts can figure out what the "reverse fusion layer" is all about, and whether it is possible to break the reverse fusion layer. ”

Zhao Huasheng nodded, took his eyes off the Hercules heavy launch vehicle, and followed Wang Tang into the operation room.

More than 100 staff members are busy in the operation room, monitoring all aspects of the data of the Hercules launch vehicle and the material storage warehouse at any time.

"I'm the commander in chief of the Crimson Heart spacecraft launch." Wang Tang said to Zhao Huasheng, "Now is the final stage of preparation, the astronauts have completed the last physical examination and are rushing here by car." The launch window is between 2 p.m. and 4 p.m., and depending on weather data, the Hercules rocket will be launched at the right time. ”

Zhao Huasheng nodded, and sat down with Li Wei and Meng Zhuo in front of the viewing table.

Perhaps it was the solemn atmosphere in the operation hall that infected Li Wei, and after sitting down, Li Wei held Zhao Huasheng's hand and whispered: "Watson, I'm a little nervous. ”

Zhao Huasheng squeezed Li Wei's hand, and also said in a low voice: "Don't be nervous, the Hercules carrier rocket is known for its high safety, and this launch will definitely be fine." ”

After placing Zhao Huasheng and the others, Wang Tang re-entered the intense work. A large amount of data needs to be analyzed by Wang Tang, and a large number of decisions need to be made by Wang Tang, so Wang Tang can't delay too long with Zhao Huasheng.

After waiting in the operation hall for more than an hour, the door of the operation hall opened again, and five astronauts wearing sky-blue spacesuits walked in in a line.

Seeing the three men, two women and five astronauts coming in, all the staff in the operation hall put down their work and stood up, and there was warm applause in the operation hall.

Wang Tang stepped forward, hugged the five astronauts one by one, and then stood aside and scanned the entire operation hall with an extremely serious expression.

"These are the five astronauts who are about to undertake our mission to explore the sun," Wang said.
