The Magpie Bridge has just had lunch, and it has been about an hour since they entered the first orbit.
At this time, their position is 4.52 million kilometers, and the orbit is 510 thousand kilometers away from the apogee, leaving about 50 thousand kilometers
Suddenly three urgent notices popped up in their communication system.
[Queqiao, pay attention to avoid the number K23671. It’s too garbage. It’s too garbage in your track. It’s detailed too garbage data … Please reply when you receive it]
[Queqiao, pay attention to avoid the number K23671, which is too rubbish …]
Yang Li instantly took action. "Yadong and Afeng are ready to start engine maneuvering evasion at any time."
After that, he sent a message to the ground command center, indicating that he had received the notice and was preparing to evade it.
Ye Yadong started the active lidar, imported the specific information of the waste, and quickly locked the specific position and flight path of the waste.
This is an abandoned solar panel from an abandoned synchronous satellite in the 1910 s
From the results of flight trajectory analysis, the probability of collision between this piece of junk and Queqiao is only about 730: 1.
However, all three people have not taken it lightly because these rubbish are often "married with children"
A lot of garbage with a diameter less than one centimeter is difficult to be accurately monitored, and after decades of roaming, this solar pool is likely to have separated very small fragments.
For a spacecraft, even a fragment the size of a screw is no less than a high-speed projectile. It is difficult for the outer protective layer of the spacecraft to resist this kinetic energy impact.
At present, the distance between the solar panel and the spacecraft is about 1736 kilometers, and the two sides show a cross track.
Yang Li didn’t recklessly risk the Magpie Bridge worth more than one billion dollars, which was a crime and a joke on his life.
Without hesitation, he ordered, "Start the main engine and auxiliary engine to rise 15 degrees first."
"Roger that"
Ye Yadong and Feng Zhang also methodically operated the engine to change the flight direction of the Queqiao.
Because Queqiao carried enough fuel for the spacecraft to complete the round trip to the Blue Star Moon, but Queqiao did not plan to return to Blue Star, so there was a lot of fuel left.
These fuels have brought great manoeuvres to the Magpie Bridge.
It’s more than enough to evade the orbit change.
After 11 minutes, calm Yang Li continued to order "resume the flight angle and continue to cruise around"
"good"
Queqiao quickly adjusted its flight path to avoid the solar pool board, which was too rubbish for the two sides to meet at close range, and the nearest distance reached ~9 kilometers.
This distance has been relatively safe.
Yang Li looked at the fuel gauge and told two teammates not to be careless. He continued to stare at the garbage.
This kind of super-high rail is too rubbish, which is very rare. It is estimated that they are lucky to encounter it this time.
However, it is also said from the side that the orbit of the blue star is full of too much garbage, especially in the near-earth orbit.
During the first cold war in the last century, Chile and the United States launched various spacecraft and experiments, many of which were left behind in the outer Pacific.
For example, NASA has launched a rocket to scatter hundreds of millions of tiny copper sheets in low-earth orbit, and some of these tiny copper sheets still remain in low-earth orbit today.
And red Lucia sent the nuclear warhead to Taitai, and there might be a nuclear warhead surface in those old military satellites.
God knows how many things they sent in those days.
The outer space seminar just concluded in June will gradually remove these old satellites which are too rubbish and pose serious risks.
The laser defense system made in China will be initially put into the project, and it is planned to spend 5~1 years to clean up 0 ~9% of the large pieces of waste in the orbit of Blue Star Department.
If the remaining garbage is less than 1 cm in diameter, it can be cleaned up again after the technology is more advanced.
The laser cannon cleaning up these wastes is mainly beneficial to the laser cannon light pressure boosting and high-temperature evaporation, which will blow the wastes out or completely evaporate them into free particles.
However, the emergence of the laser satellite defense system has also made many forces interested in developing space technology feel uncomfortable.
For their opinions, the country will naturally not listen. After all, the name of the laser satellite defense system is to defend the blue star and ensure that the orbit of the blue star can be unblocked
And his influence can’t help it. After all, the world ultimately depends on the size of the fist to decide the words.
Rich, skilled and overwhelming, why not do this?
The attitude of dealing with these barbarians is to stick and add candied dates. These guys don’t play for a long time.
With the increasing number of laser satellites, the whole blue star near-earth orbit, surface and atmosphere will cover the range of laser cannons.
The dense satellite laser cannon and the laser cannon arranged on the ground lock up most aircraft, surface ships, ground vehicles and personnel.
Including Noah’s Club, other forces are shivering. After all, these laser satellites have conducted confrontation exercises before.
Even hypersonic missiles can hardly escape laser fire. After all, this is the fastest attack of light speed weapons at present.
Cleaning up too much garbage is just a passing thing.
Of course, considering the large-scale entry into the outer space in the future, it is natural to clean up the obstacles in low-earth orbit as much as possible.
These high-speed flights are too rubbish, and there is no energy. Before shield technology, ordinary materials are hard to resist their impact, and even the material technology, spherical top flow, can’t make the spacecraft shell hard to resist these rubbish.
Of course, if high-strength materials with a thickness of tens of centimeters can be combined to build spacecraft armor, it can still resist a small piece of debris.
The problem is that it is obviously not worth the loss.
Composite armor with a thickness of tens of centimeters will bring more than ten times the dead weight to the spacecraft. For spacecraft with severe quality restrictions, a large number of effective payload protective armor will be discarded.
Usually, the thickness of spacecraft shell is usually a few centimeters to more than ten centimeters. For example, the shell of Apollo spacecraft lunar module is only 3 mm thick, and the aluminum alloy layer can be called thin skin and big stuffing.
Even if it has a thickness of more than ten centimeters, the thickness is about one or two centimeters. Its thickness is mainly filled with radiation protection layer, heat dissipation layer, heat insulation layer and insulation layer.
It is better to prepare more fuel so as to have enough power to avoid orbit change if we expect the spacecraft to resist too much garbage.
This is the unique place in today’s space field.
After avoiding the piece of rubbish, the Magpie Bridge finally circled for an hour and then returned to the perigee.
Near perigee, Yang Li carefully directed the spacecraft to maneuver again.
This time, they will orbit a larger elliptical orbit and are expected to reach an apogee of 120,000 kilometers in 46-4 hours.
After the successful orbit change, the spacecraft started the autopilot again to fly around the cruise.
