The rise of nanometers

When Ye Yadong saw that the microwave heating was completed, he opened the special plastic bag of the fast food package. Inside was mutton pilaf, which was specially made from mutton chops, yellow radish, onions, and green peas, and a part of the fat was specially reduced.

He quickly eliminated the pilaf, ate another sliced ​​apple, and drank the nutrient solution. Every time he ate something, he had to follow the operating procedures and store all food packaging and napkins in special garbage bags. .

These garbage bags will be vacuumed, stored in special garbage storage cabinets, and finally destroyed with Blue Star.

Of course, if there is an emergency, these garbage and garbage bags can also be used as emergency materials.

For example, if the indoor heat dissipation system cannot work, you can put these things into a temperature difference heating furnace to absorb indoor heat into the temperature difference heating furnace. Finally, these high-temperature garbage will be sent to the main engine combustion chamber, where it will be incinerated and ejected into ions.

It not only achieves the purpose of heat dissipation, but also can be used as the injection working fluid of the engine. At the same time, it reduces the mass of the spacecraft. It can be said that it kills three birds with one stone.

However, under normal circumstances, this special emergency plan will not be activated.

After Ye Yadong had breakfast, he went to replace Zhang Feng, and finally the captain Yang Liming.

at the same time.

At the space airport of the Eagle Space Base, after intensive testing, the Golden Wing Dapeng installed another Chang 11 launch vehicle on its back.

The spacecraft carried by this launch vehicle is the Queqiao-2 spacecraft, including the orbital spacecraft (weighing 34 tons) and the main cabin of the Guanghan Palace Base (56 tons).

At that time, Queqiao 2 will join Queqiao 2 in lunar orbit to form the Changong Space Station, and then launch the core module of the Guanghan Palace Base to the lunar surface to achieve manned lunar landing and construction of a lunar surface base.

July 4th, 12 noon.

The Golden Winged Roc once again spewed violent light red flames, rushing upward diagonally towards the top of the stratosphere.

The familiar crew completed acceleration, angle adjustment, separation and landing in one go.

This launch vehicle also successfully entered low-Earth orbit. Like yesterday's launch vehicle, it docked at the Tiangong Space Station. Two astronauts, Nie Changfeng and Shi Keji, entered the spacecraft according to the original plan.

However, they did not immediately start to leave the Tiangong Space Station, but quietly waited for news from the Queqiao.

The purpose of this is mainly to avoid interference with the Queqiao. After all, the two spacecrafts entered the lunar orbit at about the same time, which may cause the ground command center to be confused.

Therefore, the plan for Queqiao-2 is to start its mission to the moon only after Queqiao successfully enters the lunar orbit and completes the orbit determination of the Changong Space Station.

At this moment, Station Commander Li Gaoxuan received an emergency notification from the ground command center. His eyes changed, and he hurriedly activated the high-power laser communicator and sent an emergency notification to the Queqiao.

Inside the Queqiao, they had just had lunch. At this time, about 8 hours had passed since they entered the first orbit.

At this time, their position was on an orbit of 45,200 kilometers, and they were only about 5,800 kilometers away from the apogee of 51,000 kilometers.

Suddenly, three emergency notifications popped up in their communication system.

[Queqiao, be careful to avoid space junk numbered K23671. This space junk is in your forward orbit. The following is detailed space junk data... Please reply after receiving it. ]

[Queqiao, be careful to avoid space junk numbered K23671...]

Yang Liming took action instantly: "Yadong, Ah Feng, be ready to start the engine and maneuver to evade at any time."

After he finished speaking, he sent a message to the space station and the ground command center, saying that he had received the notification and was preparing to avoid it.

Ye Yadong activated the active lidar, imported the specific information of the space debris, and quickly locked the specific location and flight trajectory of the space debris.

This is an abandoned solar panel from an abandoned geostationary satellite from the 1980s.

Judging from the analysis results of the flight trajectory, the probability of this piece of space junk colliding with the Queqiao is only about one in 730.

But none of the three took it lightly, because these space junks often "drag their families with their families".

Many space junks with a diameter less than one centimeter are difficult to accurately monitor. After decades of space roaming, this solar cell has most likely separated into very small fragments.

For a spacecraft, even a screw-sized fragment is no less powerful than a high-speed armor-piercing bullet in space. The outer protective layer of the spacecraft is difficult to resist such kinetic energy impact.

Currently, the distance between the solar panels and the spacecraft is about 1,736 kilometers, and the two sides are in cross orbits.

Yang Liming was not reckless and risked the Queqiao ship worth more than one billion. That was a crime and a joke with his own life.

He ordered without hesitation: "Start the main engine and auxiliary engine, and first raise it 15 degrees."

"receive."

Ye Yadong and Zhang Feng also operated the engine in an orderly manner and began to change the flight direction of the Queqiao.

Since the fuel carried by the Queqiao itself is enough for the spacecraft to complete a round trip to the Blue Star moon, the Queqiao has no plans to return to the Blue Star, so there is a lot of surplus fuel.

These fuels give the Queqiao a large operating space.

It is more than enough to avoid derailment.

Eleven minutes later, the calm Yang Liming continued to give instructions: "Restore the flight angle and continue circling."

"OK."

Queqiao quickly adjusted its flight trajectory to avoid the solar panel space junk. The two sides would not meet at close range, and the closest distance reached 80 to 90 kilometers.

This distance is already relatively safe.

Yang Liming looked at the fuel gauge and told his two teammates not to be careless. He continued to keep an eye on the space debris.

This kind of space junk in ultra-high orbit is actually very rare. They must have been lucky to encounter it this time.

However, this also shows from the side that the internal orbit of Blue Star is filled with a lot of space junk, especially in the low-Earth orbit, there are countless.

During the first Cold War era of the last century, Lucia and the United States launched various spacecraft and experimental products, many of which were left in outer space.

For example, NASA has launched launch vehicles and scattered hundreds of millions of tiny copper pieces into low-Earth orbit. Some of these tiny copper pieces still remain in low-Earth orbit.

And Chi Lucia even sent nuclear warheads into outer space. There might be nuclear warheads on those old military satellites.

Who knows how many things they sent up there back then.

At the just-concluded Outer Space Symposium in June, these space junk, as well as old satellites that pose serious risks, will be gradually removed.

The domestically built laser defense system will initially be put into this project, and it is planned to take 5 to 10 years to clean up 80 to 90% of the large space debris in the Blue Star's internal orbit.

As for the remaining space junk with a diameter of less than 1 centimeter, we can only wait for the technology to become more advanced before cleaning it up again.

Using laser cannons to clean up these space junks mainly uses the laser cannon's light pressure boost and high-temperature evaporation to drop the space junk into outer space, or completely evaporate it into free particles.

However, the emergence of laser satellite defense systems has also made it difficult for forces interested in developing aerospace technology to sleep well and eat.

Naturally, the country will not listen to their opinions. After all, the laser satellite defense system is nominally to protect the Blue Star and ensure that the Blue Star's internal orbit can be unimpeded.

As for other forces, there is nothing they can do. After all, in this world, the size of the fist ultimately determines the right to speak.

We have money, technology, and overwhelming combat power. Why can't we do this?

In dealing with these barbarians, Huang Xiuyuan's attitude is to add a big stick and candied dates. These guys will not remember long if they don't fight.

As the number of laser satellites becomes increasingly dense, the entire Blue Star's low-Earth orbit, surface, and atmosphere will be within the range of laser cannons.

The dense satellite laser cannons, coupled with the laser cannons deployed on the ground, are enough to lock down most aircraft, surface ships, ground vehicles and personnel.

Other forces, including the Noah Society, felt trembling. After all, these laser satellites had conducted confrontation exercises before.

Even supersonic missiles cannot escape the concentrated fire of laser cannons. After all, this is the speed of light weapon, currently the fastest attack.

Cleaning up space junk is just incidental.

Of course, considering the large-scale entry into outer space in the future, it is natural to clear the obstacles in low earth orbit as much as possible.

Before the advent of technology such as energy shields, it was difficult for ordinary materials to resist the impact of these high-speed space junks. Even the Suiren system, which has the world's top material technology, could not make the outer shell of the spacecraft resist these impacts. Space junk.

Of course, if you can combine high-strength materials with a thickness of tens of centimeters to build spacecraft armor, you can still resist small fragments.

The problem is that doing so obviously does more harm than good.

Composite armor with a thickness of tens of centimeters will bring more than ten times the dead weight to the spacecraft. For spacecraft with strict mass restrictions, using a large amount of payload on protective armor is clearly a waste of time.

Usually the thickness of the shell of a spacecraft is generally about a few centimeters to more than ten centimeters. For example, the ascent shell of the Apollo spacecraft lunar module is an aluminum alloy layer only 3 millimeters thick, which can be called a thin skin but a big stuffing.

Even if it is more than ten centimeters thick, the truly protective thickness is only about one or two centimeters. The other thicknesses are mainly used to fill radiation protection layers, heat dissipation layers, heat insulation layers, and thermal insulation layers.

If we expect the spacecraft to resist space debris, it is better to prepare more fuel so that it has enough power to avoid orbit changes.

This is the helplessness of today's aerospace field.

After avoiding the piece of space junk, Queqiao finally returned to perigee after orbiting for 18 hours.

Near the perigee, Yang Liming very carefully directed the spacecraft to perform another maneuvering orbit change.

This time they will circle a larger elliptical orbit and are expected to reach apogee at 128,000 kilometers in 46 to 48 hours.

After the orbit change was successful, the spacecraft started the autopilot system again and began cruising around.

Inside Blue Star, they are also extremely concerned about the situation of the Queqiao this time, because this is the moon landing plan that humans have launched again after decades.

What's more, the scale of the Guanghan Palace Project is much larger and more ambitious than the Apollo Project. This may be the first step for mankind to enter interstellar civilization.

On the entire Internet, discussions about the future interstellar era are becoming increasingly noisy.

Today's various signs have made more and more people realize that the future of mankind may be a very bloody and cruel world.

Super technology will give birth to super overlords, which will lead to great changes in society. This technological gap between the rich and the poor is widening day by day.

And this is a trend that is difficult to reverse. Many insightful people from small and medium-sized forces have begun to wake up.
