Chapter 550

……

After completing the passenger transport, the "arc hawk 9" mission has ended and began to return to earth. Ren Hong and other eight astronauts or scientists entered Xinggang one after another under the support of Li Xingfeng.

This is the end of the live broadcast. Three hours later, more shocking pictures appeared, but unfortunately, the general public could not see it.

In the middle and lower part of "Tiangong ring orbit star harbor", two huge trusses carrying a large number of space capsule or inflatable capsule and other materials are tied to the truss. At the moment, they are separated from the ring orbit star port. The total length of the two trusses exceeds 800 meters. If extended, the maximum length will exceed km, which is twice the length of a large aircraft carrier Yu, many of them are like retractable airbags tied to the truss, and also like suction cups on Octopus limbs. The "sucker" is wrapped with materials, which is called "beam inflatable capsule". At this moment, it is in contraction state, and no gas is injected, because it is not the time.

In the third part of the truss, two spaceships are fixed, forming a diameter of 145 meters long. They are slowly rotating. The two spaceships are similar to the flat outline of matrix shape. The two spaceships are important vehicles for landing on Mars. Such outer star contour is designed according to the thin atmosphere and gravity of the fire star. Landing on Mars is bound to be a hard landing. At the moment, the two spacecrafts are respectively fixed on the main truss by two slender alloy supports with a length of 30 meters. The resistance in space can be ignored. The alloy bracket looks very thin and long, but the two vehicles for landing on Mars are extremely strong.

At the end of the truss is a centrifugal chamber, which has not been started at the moment. In addition, the central part of the truss is the core module. At present, 11 astronauts or scientists, including Ren Hong and Xiao Keri, as well as several top astronauts including Ning Zebo and Li Xingfeng, are in the core module.

They are all one of 11 people going to Mars.

It's true that this truss object with a length of more than 400 meters is firefly. Although it looks like a straight bachelor, the truss is bound with various kinds of materials. When it reaches the Mars orbit, it will have earth shaking changes, just like a transfiguration King Kong, which turns into a very complicated space station, and "beam inflates" on the truss The "space capsule" will be fully inflated, making the "Bachelor" extremely plump.

At the moment, "firefly" seems to be a straight bachelor with a length of more than 400 meters, while the artificial celestial body composed of another giant truss presents a "t" shape. It also has its own name - "Mars Express".

Ren Hong and his "Yinghuo" want to arrive at Mars without the Mars Express, which acts as the core source of transportation power like a traction locomotive.

When the two trusses are separated from the ring orbit star port, they start synchronous orbit change, and the distance between them becomes larger and larger. At this time, the two trusses start rendezvous and docking, and finally merge into one.

If you are an outsider, you will never understand. After the two trusses become one, the tail of "firefly" is just a centrifugal chamber, and the middle part does not have an engine nozzle of super large diameter like Noah.

There are only a few small engine jets at both ends of the wing, so where is the main engine? It can be seen from their calibre that the small engines can not bear much thrust. It is estimated that they are just to adjust the space station over Mars to maintain stable orbit, and it is impossible to send "firefly" and "Mars Express" to Mars.

Since "Mars Express" acts as a locomotive, it is natural to take "firefly" to Mars. However, there is no main engine propulsion nozzle on this man-made aircraft, which is really incredible.

The secret lies in the "I" shape at the beginning of the "t" shape of Mars Express, which is 260 meters long and 108 meters wide. It is a giant light sail in the shape of leaves made of alloy support. However, this area is only as large as it will be after it is shrunk. When it is fully relaxed, it will appear to be even larger A giant smooth sail in the shape of a leaf.

Three hours later, the centrifugal chamber for gravity was officially put into operation, and Ning Zebo served as the main pilot of the Mars Express. Three and a half hours after the launch of the Mars Express orbiter, the Mars Express was launched into orbit for the first time.

At this moment, Mars is almost the farthest distance from the earth. At this moment, it is estimated that the American "Noah" is about to arrive on Mars. It has been more than seven months since they set out. As far as the distance between the earth and Mars is concerned, it is estimated that it will take 850 days to arrive at Mars at Noah's speed from the earth. A one-way journey is no more than three years away.

However, the fact is that Ren Hong and his team did choose to start at this time point, not only at this time point, but also to complete the goal of sailing over 370 million kilometers and reaching Mars in 100 days.

What is the current rocket propulsion speed of mankind? The speed is about 50000 km / h, and the goal of 370 million km / h can be achieved in 100 days. This is an impossible task in the eyes of outsiders. It takes more than 20 minutes to cross such a distance at the speed of light.Of course, this is only in the eyes of outsiders, just in terms of rocket propulsion, and Mars Express is not rocket propelled.

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

When the Mars Express's giant light sail unfolds, it will be like a boat in the universe. At this time, thousands of lasers around the truss began to operate in the center of the Mars Express truss.

In the field of laser technology, China has long lost the eight streets of the United States, which has been interpreted here again. The Ming axe base has been studying laser technology, and birch is also studying it. Although "justice boy" has not been able to produce light laser attack weapons in science fiction war movies, conventional lasers have been applied here.
