However, although this exploration is mainly to explore the Kuiper belt on the periphery of the solar system, the major planets and their satellites on the way will still be explored in detail, after all, the farthest human spacecraft has gone is the asteroid belt, and it has never walked out of the asteroid belt, so for the other planets in the solar system other than the asteroid, human beings do not know much about the information obtained from various astronomical telescopes and unmanned detectors, so this exploration of these planets must be brought in it.

The main spacecraft used in this exploration are the previous Pioneer and Explorer 1 and Explorer 2.

Of course, in addition to these three spaceships, there are five other space research ships that will also join them, but the volume of the five new space research ships is not very large, and the tonnage is about 100,000 tons, but for a scientific research ship, these spaceships are already relatively large.

However, these five research ships are different from the Pioneer, Explorer 1 and Explorer 2, first of all, the armor of these five research ships is very thick, and the armor at the end of the bow even reaches about five meters thick, and the weakest part of the armor of the entire spacecraft is also one meter thick.

Moreover, the armor of these five spaceships is also the latest armor technology of Zhu Lei and Yongan Group, this kind of armor not only has a very high hardness of about 350, but also the thermal insulation effect of this special metal is also very good, so it is very suitable as the armor of the spacecraft.

And because the power plant of these five space research ships has four ultra-high-power thrusters, there are also two controllable nuclear fusion thrusters, which can make the spacecraft generate strong power, so the fastest speed of these five spacecraft will reach about 10% of the speed of light.

Therefore, the chances of survival of these five space research ships are definitely many times higher than the previous three space research ships.

Although the attack power of these five spaceships is very small, it can even be said that there are none, and all the weapons of the entire spacecraft add up to only two electromagnetic railguns and several missile launchers, but due to the special design of these five space research ships, there is no extra space to install weapons, not to mention that due to the special design of these five space research ships, their spacecraft itself is a very powerful weapon.

The five space research ships looked like a sharp sword without a hilt, and the whole spacecraft looked very neat and tidy, without any protrusions.

It is because of this special design that the entire spacecraft is a powerful weapon in its own right, and thanks to the strong armor, the spacecraft can penetrate an asteroid with a diameter of less than 500 meters when flying at full speed.

It is precisely because of this special design that these five spaceships cannot be equipped with more weapons, but as a space research ship, this is enough, because the most important thing for a space research ship is survivability, not its combat effectiveness.

Three months have passed in a blink of an eye, and at this time, the Mars program discussion on the moon is still continuing, and the five scientific research ships have been completed at this time, and these five scientific research ships are completed according to the original drawings, in addition, these five space research ships are also the first batch of spaceships in the entire Ming Empire to use controllable nuclear fusion technology, but for the sake of safety, these five scientific research ships are also equipped with ordinary nuclear power generation technology, but this technology is only used as the power supply system of the spacecraft, The second is to be used as a backup energy source for the spacecraft's engines.

After all, once these five spaceships set off, then they will be far away from the earth, and because the intensity of sunlight in the place where they are going is very weak, the spacecraft basically relies on the energy they carry to provide power, and there is no other external energy source.

After all, this exploration of the outer periphery of the solar system is not an unmanned probe, but a real manned spacecraft, and there are even famous scholars and scientists of the Ming Empire inside, so it is absolutely foolproof for safety, after all, these people are the most valuable resources of the Ming Empire.

However, compared to these five space research ships, Pioneer and Explorer 1 and 2 are relatively simple, because their main targets are other planets and their moons outside of Mars in the solar system.

After all, compared with these five space research ships, the Pioneer and the Explorer 1 and 2 are much smaller in terms of speed and survivability, and they are still relatively safe as research ships in the solar system, but if they are out of the nine planets of the solar system, then there are many hidden dangers in the safety of these three space research ships. Moreover, Pioneer, as well as Explorer 1 and Explorer 2, were designed as planetary research vessels, so they are perfectly aligned to explore the planets of the solar system.

Although these five space research ships look very similar in appearance, they actually have different functions, some of the most important functions are to detect changes in the magnetic field and space particles in the outer solar system, and some of the most important functions are to detect the distribution of asteroids in the outer solar system.

Although the tonnage of these five space research ships has reached more than 100,000 tons, because of its strong armor, the size of these five space research ships is not large, and the longest part of the entire space research ship is less than 200 meters, and the width is only less than 40 meters, and no one would think that these five space research ships will weigh more than 100,000 tons at first glance.

"How are you prepared, your task this time is very arduous, your mission this time is not only to record the data of various space, magnetic fields, particles, motion laws and so on in the outer solar system, but also to make detailed records of various asteroids, dwarf planets, comets, meteorites, etc. in the outer solar system.

Secondly, you have to record all kinds of data from the Kuiper belt, and send it back to the moon through the spacecraft's quantum communication equipment, of course, in addition to these, you also have to look for asteroids or dwarf planets or comets in the outer periphery of the solar system that can build space alert radar, after all, human beings are quite unsafe now, and it can even be said that there is no force defense. Zhu Lei looked at the eight groups of members standing in front of him, of course, the largest number belonged to the personnel of the Pioneer research ship, and the smallest number belonged to Explorer 1 and Explorer 2.
