After transporting its passengers, Arc Eagle Nine's mission is over and it's time to return to Earth. Ren Hong and other eight astronauts or scientists entered the Star Port one after another under the support of Li Xingfeng.

The live broadcast ended here. Three hours later, an even more shocking picture appeared, but it was a pity that ordinary people could not see it.

In the middle and lower parts of the "Tiangong Circum-orbit Star Port" that presents the shape of "Yu", two huge trusses carry a large number of space capsules or inflatable space capsules and other materials tied to the trusses. The total length of the two trusses exceeds 800 meters. If extended, the maximum length will exceed a kilometer, which is more than twice the length of a large aircraft carrier. Many of the trusses are tied to the trusses like shrinkable airbags. Like the suction cups on the limbs of an octopus, the "suction cups" are wrapped with materials, which is the "beam inflatable space capsule". At this moment, it is in a contracted state, and no gas is injected, because it is not yet the time.

On one-third of the truss, two spaceships are fixed, forming a diameter of 145 meters long, rotating slowly. The two spaceships are similar to the outline of a matrix-shaped flat style. The two spaceships are landing An important vehicle for Mars. Such an alien outline is designed according to the thin atmosphere and gravity of Mars. Landing on Mars must be a hard landing. At this moment, the two spaceships are respectively fixed on the main truss by two slender alloy brackets with a length of 30 meters. The resistance in space is negligible. The tool is extremely strong.

The end of the truss is a centrifuge cabin, which is not activated at the moment. In addition, the central part of the truss is the core cabin. At present, 11 astronauts or scientists including Ren Hong are already located in the core cabin. Except for Ren Hong and Shockeri, Several top astronauts including Ning Zebo and Li Xingfeng are also among them.

They are all part of 11 people who are going to Mars.

That's right, this truss object with a length of more than 400 meters is "Firefly". Although it looks like a straight stick, the truss is bundled with various materials, and when it reaches Mars orbit After that, there will be earth-shaking changes, just like Transformers, it will become an extremely complex space station, and the "beam inflatable space capsule" "packed" on the truss will be fully inflated, making this "bachelor" become Very full.

At this moment, the "Firefly" seems to be a straight stick more than 400 meters long, and another artificial celestial body formed by a huge long and large truss presents a "T" shape. It also has its own name-"Mars Express" No".

If Ren Hong and others and their "Yinghuo" want to reach Mars, they cannot do without the "Mars Express". Like a locomotive, it acts as the core source of transportation power.

When the two trusses are separated from the orbital star port,

The synchronous orbit change began, and the distance between the starport and the star port became larger and larger. At this time, the two trusses began to meet and dock, and finally merged into one.

If an outsider sees it, they will definitely not understand. After the two trusses are combined into one, the tail of the "Firefly" is just a centrifugal cabin, and the middle part does not have a large-diameter engine nozzle like the "Noah".

There are only a few small engine nozzles at the ends of the wings, so where is the main engine? Those small engines, just by looking at their calibers, we can see that they can't bear much thrust. It is estimated that they are only used to regulate the space station above Mars to maintain a stable orbit. It is impossible to put the "Firefly" and "Mars Express " to Mars.

Since the "Mars Express" is acting as a locomotive, it is natural to take the "Firefly" to Mars, but this man-made aircraft does not have any main engine propulsion nozzles, which is really incredible.

The secret lies in the "one" shape at the head of the "T" shape of the "Mars Express", which is 260 meters long and 108 meters wide at its widest point. It is a leaf-shaped giant space light made of alloy brackets. The sail, but this area is only as big as it is when it is contracted. When it is fully expanded, it will show a larger leaf-shaped giant light sail.

Three hours later, the centrifuge cabin that produces gravity was officially in operation, and Ning Zebo served as the main pilot of the "Mars Express". Three and a half hours later, the "Mars Express" took the "Firefly" space station for the first acceleration and officially left Earth orbit.

At this moment, Mars is almost the farthest distance from the current Earth, and at this moment it is estimated that the American "Noah" is about to arrive at Mars, and it has been more than seven months since they set off. As far as the current distance between the Earth and Mars is concerned, it is estimated that it will take 850 days to reach Mars after departing from the Earth at the speed of Noah, and it will take nearly three years for a one-way journey.

But the fact is that Ren Hong and the others did choose to start at this time period, not only at this time point, but also to complete the goal of traveling a distance of more than 370 million kilometers and reaching Mars within 100 days.

What is the current speed of human rocket propulsion? The speed is about 50,000 kilometers per hour, and the goal of completing 370 million kilometers within 100 days is a fantasy to outsiders. It is an impossible task. It takes more than 20 minutes to travel such a distance at the speed of light. time.

Of course, this is only in the eyes of outsiders, only in terms of rocket propulsion, and the "Mars Express" is not propelled by rockets.

At 4 hours and 37 minutes, the giant sail of the "Mars Express" far away from the earth was officially launched in space. This "leaf" gradually stretched from the longest length of less than 300 meters, and finally reached an incredible 16.8 kilometers. The length, such an exaggerated length of the giant light sail has three layers, and the distance between each layer of light sail is only 48 meters, which looks like one layer from a distance.

When the giant light sail of "Mars Express" is unfolded, it looks like a flat boat in the universe. At this time, the thousands of sets of lasers surrounding the truss in the center of the truss of the "Mars Express" began to operate, and the amethyst with high energy reserves inside the aircraft provided stable energy output for these thousands of sets of lasers.

In the field of laser technology, China has already left the Americans eight streets, and it is interpreted here again. The Dark Ax Base has been researching laser technology, and Bai Hua is also researching. Although "Justice Boy" failed to create the light laser in the sci-fi war movie Assault weapons, but here, conventional lasers have been used.
